No. 12-24-36480 IN THE SUPREME COURT OF CRAWFORD SPRING TERM 2012 VORTEX RECREATIONAL SYSTEMS, Petitioner, v. JENNIFER BATES, Respondent. On Writ of Certiorari to the Crawford Court of Appeals for the Fifth District Wells County BRIEF FOR RESPONDENT Team 18 Counsel for Respondent QUESTIONS PRESENTED I. Whether the Affidavit of Mr. Sullivan, a rafting instructor on the Crawford River and the Materials Testing Report of Mr. Robinson, a student intern at Vortex Recreational Systems hired to test materials used to make the Splash Rower, have unreliable and irrelevant bases such that the trial judge should have never admitted them as expert evidence under Crawford Rule of Evidence 905 and the framework set forth in Daubert. II. Whether the Splash Rower contained manufacturing, design and warning defects when it malfunctioned, when Vortex Recreational Systems knew of an alternative safer design, and when the product’s warning failed to inform Ms. Bates of the foreseeable dangers of using the Splash Rower for recreational purposes. III. Whether Vortex Recreational System’s manufacturing, design and warning defects substantially caused Ms. Bates’ injuries when she kayaked down the Crawford River using her brand new Splash Rower in a reasonably foreseeable manner. i TABLE OF CONTENTS QUESTIONS PRESENTED..................................................................................................i TABLE OF CONTENTS.......................................................................................................ii TABLE OF AUTHORITIES .................................................................................................iii STATEMENT OF THE CASE ..............................................................................................1 SUMMARY OF THE ARGUMENT ....................................................................................5 ARGUMENT .........................................................................................................................6 I.

Vortex Recreational Systems, No. 10-CV-9568 (Craw. Com. Pl. 2010). The decision of the Crawford Court of Appeals for the Fifth District of Wells County appears in Bates v. Vortex Recreational Systems, No. 45-CA-90180 (Craw. Ct. App. 2011). STATEMENT OF CASE I. Statement of Facts Plaintiff, Jennifer Bates, is a twenty-four year old woman who resides in the State of Crawford. (R. at 4.) In 2004, Ms. Bates lost her left forearm in a car collision resulting in her use of a prosthetic arm. (R. at 5.) Vortex Recreational Systems (“Vortex”) manufactures and sells recreational prosthetic attachments, including the Splash Rower. (R. at 2.) The Splash Rower attaches to any standard prosthetic limb and allows an amputee the functionality of a natural limb to grasp a paddle. (R. at 2.) The Splash Rower attachment consists of two interlocking parts. (R. at 3.) Part A latches onto the shaft of the paddle like a clinched fist, and Part B simulates an elbow to allow for full range of motion. (R. at 3.) Part B connects the user’s prosthetic limb to Part A by securing Part A’s pegs into Part B’s peg holes. (R. at 3.) The other end of Part B screws onto any standard prosthetic limb. (R. at 3.) Vortex considered both graphite and iron as materials for its product, but ultimately chose to manufacture the Splash Rower almost entirely out of graphite. (R. at 3.) Also, graphite has greater flexibility and sold for twenty percent less than iron. (R. at 3.) In October of 2009, Vortex worried about the strength of graphite. (R. at. 3.) It hired Michael Robinson, a student intern studying combat engineering at Crawford Tech University, to 1 conduct materials testing on the Splash Rower. (R. at 4.) Dr. Gregory Scott, an engineering professor at Crawford Tech University, supervised Mr. Robinson’s work and met him on four occasions throughout the four-week testing period, where Mr. Robinson worked for a total of sixty hours. (R. at 3.) Mr. Robinson tested sixty Splash Rowers, thirty made of iron and thirty made of graphite, in a motorized lap pool set at the following speeds: three mph, seven mph, and ten mph. (R. at 4.) He tested each Splash Rower for twenty minutes, ten minutes with the water flowing against the paddle and ten minutes with the water flowing behind the paddle. (R. at 4.) At each speed, all thirty iron Splash Rowers remained attached to the paddle with no physical change. (R. at 4.) At the highest speed, two of the thirty graphite Splash Rowers slightly bent. (R. at 4.) None of the attachments snapped during the testing. (R. at 4.) Vortex chose graphite as the material for the Splash Rower based on Mr. Robinson’s testing. (R. at 4.) In December of 2009, Vortex began manufacturing and selling the graphite Splash Rower. (R. at 4.) In June of 2010, Ms. Bates purchased a Vortex Splash Rower to enjoy water sports again. (R. at 5.) Vortex packaged the Splash Rower in camouflage and marketed its product to veterans. (R. at 5.) The attachment came with a brochure and a slip of paper with the words “FOR RECREATIONAL USE ONLY” written in bold red letters. (R. at 5.) After receiving the Splash Rower, Ms. Bates went to a local sporting goods store and bought a new one-person kayak, a double-ended paddle and a life jacket. (R. at 5.) On June 22, 2010, Ms. Bates took her equipment and went on a twenty-mile kayaking trip down the Crawford River. (R. at 5.) Although June had been one of the rainiest months in Crawford, the weather that morning was clear and sunny. (R. at 5.) As Ms. Bates’ kayak approached a narrow passage, the river began to pick up speed and she struggled to maneuver 2 her kayak around the exposed rocks and floating branches. (R. at 5.) She tried to slow her kayak by dunking her paddle deep into the water and alternating from side to side. (R. at. 5.) Suddenly, the Splash Rower snapped and detached, causing Ms. Bates to lose her paddle. (R. at. 5.) Her kayak spun around vigorously and capsized. (R. at 5.) The river pulled Ms. Bates underwater and smashed her against a cluster of rocks. (R. at. 5.) Eventually, her life jacket floated her to the surface, but once above the water, she could not move her legs to swim to safety. (R. at 5.) She floated a mile downstream before a fisherman pulled her from the water and took her to the hospital. (R. at 6.) Ms. Bates suffered a severe spinal injury from the accident causing permanent paralysis from the waist down. (R. at. 6.) II. Procedural History Ms. Bates filed a complaint against Vortex in the Wells County Common Pleas Court. Ms. Bates alleged products liability claims against Vortex for manufacturing, design and warning defects of its Splash Rower. (R. at 6.) On September 28, 2010, the Wells County Common Pleas Court excluded Mr. Robinson’s Materials Testing Report as expert evidence, admitted Mr. Sullivan’s Affidavit as expert testimony, and granted summary judgment in favor of Vortex on Ms. Bates’ manufacturing, design and warning defect claims. (R. at 8, 11.) Ms. Bates filed a timely notice of appeal. (R. at 12). On May 25, 2011, the Crawford Court of Appeals for the Fifth District of Wells County affirmed in part, reversed in part, and remanded the judgment of the Wells County Common Pleas Court. (R. at 12). The Crawford Court of Appeals affirmed the inadmissibility of Mr. Robinson’s Materials Testing Report, reversed the trial court’s decision to admit Mr. Sullivan’s Affidavit, and reversed the trial court’s decision to grant summary judgment in favor of Vortex 3 on Ms. Bates’ manufacturing, design and warning defect claims. (R. at 13-15.) The Supreme Court of Crawford granted Vortex’s petition for writ of certiorari. (R. at 16.) 4 SUMMARY OF ARGUMENT The Wells County Common Pleas Court improperly admitted Mr. Sullivan’s Affidavit as expert evidence because the Affidavit contains his subjective opinions as a rafting guide and likewise, is irrelevant in a case involving a kayaking accident. In contrast, the Wells County Common Pleas Court properly excluded Mr. Robinson’s Materials Testing Report because of its unreliability and irrelevancy based on his lack of experience, inadequate testing, and flawed methodology. Furthermore, Vortex is liable for Ms. Bates’ injuries for the following reasons. Ms. Bates presents sufficient evidence to establish an inference of the Splash Rower’s manufacturing defect. Also, Ms. Bates shows that Vortex had available a safer alternative design to the unreasonably dangerous graphite Splash Rower. Alternatively, Ms. Bates established design defect under a limited two-prong approach that applies a consumer expectation standard to circumstances that give rise to an inference of product defect. Finally, Vortex failed to provide Ms. Bates with adequate warning of the foreseeable dangers posed by the Splash Rower. Additionally, Ms. Bates established an inference of a casual connection between her injuries and the Splash Rower’s manufacturing defect. The Splash Rower’s new condition and Ms. Bates’ normal foreseeable use links the defect to the injury. Vortex defectively designed the Splash Rower because Ms. Bates’ reasonably used it in a foreseeable manner. Lastly, Vortex did not provide an adequate warning label and thus Ms. Bates could not assess the potential risks involved with using the Splash Rower. 5 ARGUMENT I. NEITHER THE AFFIDAVIT NOR THE MATERIALS TESTING REPORT SHOULD BE ADMITTED AS EXPERT EVIDENCE. The Wells County Common Pleas Court should not have admitted the Affidavit as expert evidence. Trial court decisions receive a deferential “abuse of discretion” standard of review for the admission or exclusion of expert opinion testimony challenged under Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579 (1993). See Gen. Elec. Co. v. Joiner, 522 U.S. 136, 141 (1997) (holding abuse of discretion as the appropriate standard to review a district court’s evidentiary rulings). The appellate court gives deference to the trial court’s decision and assesses the trial judge’s special role as the gatekeeper to ensure reliability and relevance of scientific, technical or skill-based expert testimony. Kumho Tire Co. v. Carmichael, 526 U.S. 137, 147 (1999). Under an abuse of discretion standard, a court must review the district court’s reasoning and reverse if the district court erred after weighing the relevant factors in reaching its conclusions. Westberry v. Gislaved Gummi AB, 178 F.3d 257, 261 (4th Cir. 1999) (citing Wilson v. Volkswagen of Am., 561 F.2d 494, 503 (4th Cir. 1977)). In deciding whether a trial court abused its discretion, many appellate courts apply abuse of discretion “with teeth” and closely examine the trial court’s determining factors—“whether it omitted a key factor, improperly applied a factor, or inappropriately balanced the applied factors.” Victor E. Schwartz & Cary Silverman, The Draining of Daubert and the Recidivism of Junk Science in Federal and State Courts, 35 Hofstra L. Rev. 217, 265 (2006). In the present case, the Wells County Common Pleas Court abused its discretion when it improperly assessed the proffered expert evidence before choosing to admit it. 6 A. This Court Should Not Admit the Affidavit and the Materials Testing Report As Admissible Expert Evidence Under Crawford Rule 905 and Daubert Because Both Lacks Reliability and Relevancy. Under Crawford Rule 905 and Daubert, both the Affidavit and the Materials Testing Report are inadmissible expert evidence. The Crawford Rules of Evidence and the framework in Daubert confirm that an expert’s opinions must rest on a relevant and reliable foundation based on factors appropriate to the expert’s particular discipline. Daubert, 509 U.S. at 589; Craw.R.Evid. 905(b). Before a trial court admits expert evidence, Daubert requires the trial judge to act as gatekeeper. Id. Although Joiner reiterated the flexibility that trial courts have as gatekeepers, an expert’s conclusions must reliably connect to the underlying evidence and analytical data used by the expert. Gen. Elec. Co., 522 U.S. at 146. Similarly, Kumho Tire Co. reaffirmed that courts must guarantee that the expert testimony “employs in the courtroom the same level of intellectual rigor that characterizes the practice of an expert in the relevant field.” Kumho Tire Co., 526 U.S. at 152. The trial court, in an initial determination as gatekeeper of proffered testimony, must ensure (1) the reliability of the evidence and that it concerns scientific, technical, or other specialized knowledge and (2) the relevancy of the evidence in order to assist the trier of fact in understanding or resolving a fact at issue. Craw.R.Evid. 905(e). The proponent of the expert testimony bears the burden of showing the reliability and relevancy of the evidence. Lemmermann v. Blue Cross Blue Shield, 713 F. Supp. 2d 791, 797 (E.D. Wis. 2010). 1. Testimony must be reliable and rise above a subjective opinion. Under the first prong, expert evidence must be reliable. Regardless of whether the proffered testimony concerns scientific, technical, or other specialized knowledge, it must have a reliable basis in the knowledge and experience of the appropriate discipline. Daubert, 509 U.S. at 7 592. See Kumho Tire Co., 526 U.S. at 149; see also Walker v. Soo Line R.R., 208 F.3d 581, 586 (7th Cir. 2000). Also, evidence becomes reliable only when it rises above subjective belief or unsupported speculation. Daubert, 509 U.S. at 590. Additionally, Daubert provided a nonexhaustive list of “guideposts” for the court to consider when analyzing the reliability of proffered testimony: (1) whether the scientific theory can be or has been tested; (2) whether the theory has been subjected to peer review and publication; (3) whether the theory has a known potential error rate; and (4) whether the theory has been generally accepted in the relevant scientific, technical, or professional community. Id. at 593-94. For scientific testimony, a court will find expert testimony unreliable when an expert draws conclusions from data based on flawed methodologies. Loeffel Steel Prods. v. Delta Brands, Inc., 387 F. Supp. 2d 794, 817 (N.D. Ill. 2005). Likewise, a court will find non-scientific expert testimony unreliable when the trial court applies the Daubert factors and, in reaching its decision, finds no reliable basis for the proffered testimony. Kumho Tire Co., 526 U.S. at 152. 2. Testimony must be relevant in order to assist the trier of fact in understanding or resolving a fact at issue. The second prong requires that the expert testimony is relevant. A court will find evidence relevant when it has “any tendency to make the existence of any fact that is of consequence to the determination of the action more probable or less probable than it would be without the evidence.” Daubert, 509 U.S. at 587; Craw.R.Evid. 602. Expert evidence must have a significant relationship to the issues in the case with a reliable foundation as its basis or else the trial judge should deem it as irrelevant and exclude it. Id. at 590. Based on these guiding principles, the Wells County Common Pleas Court abused its discretion by admitting Mr. Sullivan’s Affidavit. The Court should have found Mr. Sullivan’s Affidavit unreliable because it contains his subjective opinions as a rafting guide and likewise, is 8 irrelevant in a case involving a kayaking accident. In contrast, the Wells County Common Pleas Court properly excluded Mr. Robinson’s Materials Testing Report because of its unreliability and irrelevancy based on his lack of experience, inadequate testing, and flawed methodology. Accordingly, this Court should affirm the Appellate Court’s decision regarding the inadmissibility of Vortex’s proffered expert evidence. B. Mr. Sullivan’s Affidavit Does Not Qualify as Expert Evidence Because His Subjective Opinions Make It Unreliable and His Experiences as a Rafting Guide Are Irrelevant. The Wells County Common Pleas Court abused its discretion for two reasons when it improperly admitted Mr. Sullivan’s Affidavit as expert evidence. First, Mr. Sullivan’s subjective opinions make his Affidavit unreliable. Second, the Wells County Common Pleas Court did not even consider the second prong of admissible expert evidence—the irrelevancy of Mr. Sullivan’s Affidavit. Mr. Sullivan’s observations as a rafting guide on the Crawford River do not translate into relevant evidence for an accident involving a kayaker. 1. The Affidavit is unreliable expert evidence. Mr. Sullivan’s Affidavit contains unreliable information. Reliable expert testimony must rise above a subjective opinion. Id. at 589-90. In order to discover the subjectivity of an opinion, Daubert provided the four guideposts for reliable expert testimony. Id. at 59394. Applying the Daubert factors to Mr. Sullivan’s Affidavit, this Court should find that the Wells County Common Pleas Court abused its discretion when it admitted Mr. Sullivan’s Affidavit as expert evidence. In the present case, besides his own conclusions, no other evidence exists to support Mr. Sullivan’s Affidavit. In other words, no relevant publications or peer review articles exist on Mr. Sullivan’s theories about how the Crawford River’s conditions—its speed, challenges, and 9 physical health requirements—would affect kayaking on the Crawford River. Thus, this Court should not reasonably view Mr. Sullivan’s conclusions as anything more than his own subjective opinions. For example, one conclusion in his Affidavit stated he would “strongly discourage any rafter with a health problem or in a limited physical condition from attempting to raft in the Crawford River.” (R. at 21.) Yet, under the Daubert factors this conclusion contains subjective opinions making it unreliable. Nothing indicates Mr. Sullivan has any scientific expertise or knowledge to assert the appropriate physical strength or physical condition necessary to raft the Crawford River. For Mr. Sullivan, as a rafter, the mutually supportive group structure of rafting makes the physical condition of a fellow rafter important. Jeff Bennett, The Complete Whitewater Rafter 178 (Jonathan Eaton et al. eds., 1996). However, for Ms. Bates, she kayaked alone and relied solely on her own physical condition. In actuality, “the freedom” offered by kayaking can downplay “the barriers presented by disabilities.” Janet A. Zeller, Canoeing and Kayaking for People With Disabilities 2 (Laurie Guillion et al. eds., 2d ed. 2009). While Mr. Sullivan does have thirty years of experience rafting on the Crawford River, fifteen as a rafting guide, rafting experience does not translate into kayaking experience. The amount of time that Mr. Sullivan spent on the Crawford River as a rafter does not then create reliable expert testimony in this case involving a kayak. Therefore, the Wells County Common Pleas Court should not have admitted the unreliable Affidavit. 10 2. The Affidavit is irrelevant expert evidence. Similarly, Mr. Sullivan’s Affidavit includes irrelevant content not related to this case. The Wells County Common Pleas Court erred when it never assessed the relevancy of the Affidavit and failed to properly act as gatekeeper for proffered expert evidence. The Affidavit’s irrelevancy resides in the following reasons. First, as seen above, the Affidavit does not have a reliable foundation as its basis under Daubert because of Mr. Sullivan’s deficiencies in the appropriate field of kayaking—he is a rafting instructor, not a kayaker. Second, the Affidavit does not make it more probable or less probable that the Splash Rower had manufacturing, design or warning defects or substantially caused Ms. Bates’ injuries because of the numerous differences between rafting and kayaking listed below. For example, Mr. Sullivan most likely did not travel through the same narrow passageway where Ms. Bates lost control of her kayak. Compared to the wide design of a raft, the slender design of a kayak allows it to easily travel through narrow passageways. Jeff Bennett, The Complete Whitewater Rafter 178 (Jonathan Eaton et al. eds., 1996). Some people even use kayaks as a safety procedure to investigate rapids and signal the safest route for the rafts. Ralf Buckley, Adventure Tourism 45 (2006). Second, usually only one or two people ride in a kayak compared to a group of people that ride in a raft. Jeff C. Young, Running the Rapids: White-Water Rafting, Canoeing, and Kayaking 13 (Megan M. Gunderson et al. eds., 2011). An increase in body weight changes the speed of a raft, which may affect how fast a rafter thinks the river flows. Rafts also have different buoyancy than kayaks. Jeff Bennett, The Complete Whitewater Rafter 172 (Jonathan Eaton et al. eds., 1996). Third, a river’s speed can change every day due to an increase in rain and obstacles, like rocks and branches that create eddies, or swirling of water. Jeff Bennett, The Complete Whitewater Rafter 60-61 (Jonathan Eaton et al. 11 eds., 1996). Finally, hydraulics, or holes in the riverbed, can grab hold of a kayaker and cause them to lose control, whereas the weight of the raft may allow it to punch straight through the same hydraulic. Jeff Bennett, The Complete Whitewater Rafter 96 (Jonathan Eaton et al. eds., 1996). Due to these differences between kayaks and rafts, Mr. Sullivan’s Affidavit does not make it more probable or less probable that the Splash Rower caused Ms. Bates’ injuries. Therefore, the Wells County Common Pleas Court improperly admitted the Affidavit as relevant expert evidence. In conclusion, the Wells County Common Pleas Court abused its discretion for two reasons when it incorrectly ruled the Affidavit as admissible expert evidence. Mr. Sullivan’s Affidavit became unreliable when he asserted his own subjective opinions. Concomitantly, Mr. Sullivan’s rafting experience is irrelevant in a case involving a kayaker. Vortex fails to meet its burden of proving the relevancy and reliability of Mr. Sullivan’s Affidavit. C. Michael Robinson’s Materials Testing Report Does Not Qualify as Expert Evidence Because He Lacks Experience with Materials Testing, He Used Flawed Methodology and He Performed Inadequate Testing Procedures. Moreover, the Wells County Common Pleas Court properly excluded Mr. Robinson’s Materials Testing Report as expert evidence. The Report is both unreliable and irrelevant because of his lack of experience with materials testing, flawed methodology and inadequate testing procedures. 1. The Materials Testing Report is unreliable expert evidence. Mr. Robinson’s lack of knowledge and experience in the field of materials testing makes his Materials Testing Report unreliable. Mr. Robinson did not yet earn his undergraduate college degree in combat engineering when Vortex hired him to test materials for the Splash Rower. (R. at 4.) Under the Daubert factors for reliability, nothing in the record indicates that an engineer 12 tested Mr. Robinson’s theory of appropriate materials for the Splash Rower. Also, no relevant publications or peer review articles were written about Mr. Robinson’s Report, and no one in the field of materials testing generally accepted his findings. Similarly, Mr. Robinson’s inadequate testing procedure and methodology also makes his Materials Testing Report unreliable. For scientific testimony, like a Materials Testing Report, unreliable conclusions derive from flawed methodologies. Loeffel Steel Prods., 387 F. Supp. 2d at 817. A judge must consider the scientific validation of a methodology and determine if the methodology applies appropriately to the facts of the case. Id. In this case, Mr. Robinson wrote his Materials Testing Report based on unreliable, flawed methodology. Mr. Robinson initially concluded that in addition to graphite, Vortex could also produce the Splash Rower from iron. (R. at 3.) However, based on Mr. Robinson’s testing and the cheaper cost of graphite, Vortex chose graphite as a more suitable material to use. (R. at 3.) Additionally, Mr. Robinson based his Report on inadequate testing procedures. First, Mr. Robinson spent only twenty-five out of his sixty work hours actually testing the materials. (R. at 4.) He tested sixty Splash Rowers—thirty made of iron and thirty made of graphite—for twenty minutes each. (R. at 4.) Second, Mr. Robinson only tested how the Splash Rower would perform in a maximum ten mph current. Third, he also never tested how heavy rain, narrow areas of a river or obstacles like rocks and logs would affect the Splash Rower. Finally, Mr. Robinson never actually tested the Splash Rower in a real river or with an actual person who used prosthetic recreational devices. Thus, in addition to his lack of experience, Mr. Robinson’s inadequate testing of the Splash Rower makes his Report unreliable. Moreover, Dr. Scott’s supervision does not convert Mr. Robinson’s Materials Testing Report into reliable expert evidence. Mr. Robinson alone generated the conclusions in his 13 Materials Testing Report. Dr. Scott supervised Mr. Robinson’s testing process of materials, but only met with him four times over the four-week period. Similar to the decision of the Loeffel court, this Court should not admit scientific conclusions as expert evidence based on unreliable or speculative information. Here, Dr. Scott specializes in chemical engineering and like Mr. Robinson, also lacks any materials testing experience. (R. at 4.) Dr. Scott provided only cursory supervision of Mr. Robinson during his internship at Vortex. (R. at 4.) Therefore, like in Loeffel, Dr. Scott’s supervision does not make Mr. Robinson’s Materials Testing Report reliable. For the aforementioned reasons, the Wells County Common Pleas Court did not abuse its discretion in excluding the unreliable Materials Testing Report because of Mr. Robinson’s lack of experience in the materials testing field, his flawed methodology and inadequate testing procedures. 2. The Materials Testing Report is irrelevant expert evidence. In addition, this Court should not admit the Materials Testing Report as relevant expert evidence because Mr. Robinson did not base his Report on a reliable foundation. As stated above, Mr. Robinson lacked experience in the materials testing field, used flawed methodology and performed inadequate testing on the Splash Rower. Consequently, this Court should only choose to admit the Report to show Vortex’s awareness of a reasonable alternative iron design to the graphite Splash Rower. However, this can be done by admitting the Report as non-expert lay testimony. Like the Wells County Common Pleas Court held, Mr. Robinson’s Report “amounts to no more than a well done student project.” (R. at 7.) As a result, Vortex fails to meet their burden of proving the reliability and the relevancy of its proffered expert evidence. 14 D. In the Alternative, the Probative Value of Including Either the Affidavit or the Materials Testing Report Does Not Substantially Outweigh the Prejudicial Effect. In the alternative, the probative value of the Affidavit or Materials Testing Report does not substantially outweigh the prejudicial effect that the evidence would have on a jury. The difficulty courts have evaluating proffered expert testimony makes expert evidence both powerful and misleading. Daubert, 509 U.S. at 595; Richard T. Stilwell, Kumho Tire: The Battle of the Experts Continues, 19 Rev. Litig. 193, 194 (2000). As a result, a judge must weigh the possible danger of unfair prejudice over the evidence’s probative uses. Daubert, 509 U.S. at 595; see Westberry, 178 F.3d at 261 (reminding the court that the “potential persuasiveness of expert testimony could confuse the jury rather than enlighten them”). If the Court admits either the Affidavit or Materials Testing Report as expert evidence, it will have a prejudicial effect on this case. The prejudicial effect of irrelevant and unreliable evidence certainly outweighs any probative value of either item of evidence. The reason why the trial judge needs to properly act as the gatekeeper and evaluate both reliability and relevancy is because it helps to alleviate the risk of unfair prejudice. Daubert, 509 U.S. at 595. Nonetheless, in the present case, the Wells County Common Pleas Court abused its discretion when it never assessed the relevancy of Mr. Sullivan’s Affidavit before admitting it as expert evidence. Even if this Court chooses to admit either the Affidavit or the Materials Testing Report as expert evidence and believes their probative value is strong enough for the jury to hear, the court should at least reassess Ms. Bates’ claims. In a minimum, her case deserves the opportunity for reconsideration in front of a competent and fair trier of fact. This opportunity would finally determine the validity of the Affidavit and Materials Testing Report under a correct analysis of excluding expert evidence. For these reasons, this Court should affirm the judgment of the court 15 of appeals and reverse the lowest court’s decision to admit the Affidavit and affirm its decision to exclude the Materials Testing Report. II. MS. BATES SET FORTH SUFFICIENT EVIDENCE TO ESTABLISH THAT THE SPLASH ROWER CONTAINED MANUFACTURING, DESIGN AND WARNING DEFECTS. Ms. Bates set forth disputed material facts that preclude summary judgment on her claims for manufacturing, design and warning defects. Courts review summary judgment under a de novo standard of review. Craw. R. Evid. 98. Under de novo, reviewing courts make an original appraisal of all evidence and afford no deference to lower decisions. Bose Corp. v. Consumers Union of U.S., Inc., 466 U.S. 485, 514 n.31 (1984). Courts should grant summary judgment only when no genuine issue of material fact exists, and when the nonmoving party is entitled to judgment as a matter of law. Craw. R. Civ. Proc. 56; Celotex Corp. v. Catrett, 477 U.S. 317, 323 (1986). In deciding summary judgment, a court must not ask whether the evidence unmistakably favors one side, but whether a reasonable jury could find for the plaintiff. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 252 (1986). In the present case, Ms. Bates brought suit under the Crawford Product Liability Act (the “Act”), which follows the Restatement (Third) of Torts: Products Liability (1998) (“Restatement”). (R. at 8.) The Restatement provides three types of product defects that give rise to manufacturer liability: manufacturing, design, and warning. Restatement (Third) of Torts: Prods. Liab. § 2 (1998). Here, Ms. Bates set forth sufficient evidence to warrant an inference that Vortex’s Splash Rower contained a manufacturing defect. Furthermore, Ms. Bates established design defect by proving that Vortex had available a safer alternative Iron Splash Rower when it distributed her unreasonably dangerous graphite product. Alternatively, Ms. Bates established design defect under a risk-utilities balancing test or a consumer expectations 16 standard to circumstances that give rise to an inference of product defect. Lastly, Vortex failed to provide Ms. Bates with adequate warning of the foreseeable dangers posed by the Splash Rower. A. Ms. Bates Raises the Inference of a Manufacturing Defect with Circumstantial Evidence of the Splash Rower’s Malfunction. Ms. Bates presented sufficient circumstantial evidence to warrant an inference that the product contained a manufacturing defect. A product contains a manufacturing defect when it departs from its intended design despite the exercise of reasonable preparation and marketing. Id. (a). Thus, the Restatement imposes strict liability for manufacturing defects. Id. At § 2 cmt. A. Ordinarily, an injured party must prove that a product contained a particular manufacturing defect while in the manufacturer’s control. Id. § 2 cmt. C. However, the Restatement does not require proof of a specific defect where a plaintiff suffers an injury of the kind that typically results from product malfunction, and not the result of other causes. Id. § 3. Likewise, the Crawford Supreme Court permits an inference of a manufacturing defect when supported by sufficient circumstantial evidence, or evidence negating other causes of the product’s failure. Bentley v. Autumn Creek, Inc., 435 Crawford 220 (2009). In fact, common sense dictates that some injuries do not occur absent some product malfunction, and fairness requires an inference of defect. Myrlak v. Port Auth., 723 A.2d 45, 52 (N.J. 1999). Ms. Bates suffered the kind of harm that ordinarily occurs when a prosthetic attachment malfunctions. Vortex designed the Splash Rower to latch onto a paddle like a “clinched fist.” (R.at 3.) While maneuvering the Crawford River, Ms. Bates’ Splash Rower snapped. (R. at 5.) As a result, she lost her paddle and became victim to the river’s current and submerged hazards. (R. at 5.) This incident would not have occurred absent a product malfunction because Vortex designed the Splash Rower to keep an amputee’s prosthetic limb affixed to her paddle. See 17 McCorvey v. Baxter Healthcare Corp., 298 F.3d 1253, 1259 (11th Cir. 2002) (explaining that evidence of a product’s failure to perform a manufacturer’s intended function supports an inference of a manufacturing defect). Additionally, the malfunction occurred during Ms. Bates’ first use of her new Splash Rower. (R. at 5.) New or nearly new products provide strong circumstantial support for an inference of a product defect. See Jarvis v. Ford Motor Co., 283 F.3d 33, 46 (2d Cir. 2002) (finding that a reasonable jury could infer a product defect when a sixday old automobile malfunctioned); and Shaun T. Mian Corp. v. Hewlett-Packard Co., 237 S.W.3d 851, 867 (Tex. 2007) (reasoning that new, undamaged and non-abused printers do not ordinarily catch fire absent a product defect). Lastly, the Wells County Common Pleas Court improperly concluded that Ms. Bates failed to negate her own misuse as a cause of the Splash Rower’s malfunction. See Rudd v. GMC, 127 F. Supp. 2d 1330, 1346 (M.D. Ala. 2001) (allowing an inference of a manufacturing defect where plaintiff’s own testimony negated misuse); and Barnard v. Saturn Corp., a Barnard v. Saturn Corp., 790 N.E.2d 1023, 1028 (Ind. App. 2003) (explaining that a jury should decide whether a plaintiff’s misuse precludes recovery on a manufacturing defect claim). Moreover, Ms. Bates deserves to have all circumstantial evidence heard by a trier of fact. The Restatement expressly provides that circumstantial evidence “may offer the plaintiff the only fair opportunity to recover” when she cannot directly examine a lost or destroyed product. Restatement (Third) of Torts: Prods. Liab. § 3 cmt. B (1998). Here, Ms. Bates cannot retrieve the portion of her Splash Rower that remained attached to the paddle she lost during her accident on the Crawford River. Consequently, she cannot present direct evidence of a specific manufacturing defect. Her position underscores the very purpose behind Section 3 of the Restatement: “to allow a plaintiff to prove a case by circumstantial evidence when there simply 18 is no direct evidence of precisely how or why the product failed.” David G. Owen, Manufacturing Defects, 53 S.C. L. Rev. 851, 874 (2002). Accordingly, this Court should reverse the Crawford Court of Appeals’ ruling on Ms. Bates’ manufacturing defect claim. B. Ms. Bates Established a Design Defect by Showing that Vortex Had Available an Economically and Technically Feasible Alternative Iron Splash Rower When It Manufactured the Graphite Product that Later Malfunctioned. Ms. Bates also set forth sufficient evidence on her design defect claim to preclude summary judgment. The Restatement provides that a product contains design defects when its foreseeable risks of harm could have been reduced or avoided by the adoption of a reasonable alternative design (“RAD”) and omission of the alternative design renders the product not reasonably safe. Restatement (Third) of Torts: Prods. Liab. § 2 (1998) (b)(b). States generally apply one of three standards for determining a defective design: (1) explicitly requiring proof of a RAD; (2) a risk-utility balancing test that implicitly requires proof of a RAD; or (3) a consumer expectations test that does not require proof of a RAD. (R. at 10.) In addition, injured parties must establish that the product was not reasonably safe. Restatement (Third) of Torts: Prods. Liab. § 2(b). Under the risk-utility analysis, products are unreasonably dangerous if an alternative design would have led to improved safety in an economic and technically feasible manner. Maxwell v. Howmedica Osteonics Corp., 713 F. Supp. 2d 84, 91 (N.D.N.Y. 2010). Here, Ms. Bates proved a RAD. She introduced the Materials Testing Report as relevant non-expert evidence of Vortex’s available alternative Iron Splash Rower, which had economic and technical practicability at the time of distribution. 1. Ms. Bates proved a RAD by introducing the Materials Testing Report. Ms. Bates proved a RAD by introducing the Materials Testing Report as relevant lay testimony of Vortex’s available, safer iron alternative to graphite. Alternatively, Ms. Bates need 19 not establish a RAD if this Court adopts a limited two-prong approach that applies a consumer expectations standard in res ipsa-like circumstances. a. The Materials Testing Report establishes a RAD. Most jurisdictions require proof of a RAD. Restatement (Third) of Torts: Prods. Liab. § 2 (1998), Reporter’s Note, cmt. d. Some states explicitly mandate that plaintiffs prove a RAD as a prerequisite to their design defect claim. Smith v. Louisville Ladder Corp., 237 F.3d 515, 518 (5th Cir. 2001) (applying Texas law); GMC v. Jernigan, 883 So. 2d 646, 662 (Ala. 2003); Voss v. Black & Decker Mfg., 450 N.E.2d 204, 208 (N.Y. 1983). Others employ a general riskutility analysis that implicitly requires proof of a RAD. Dart v. Wiebe Mfg., 709 P.2d 876, 879 (Ariz. 1985). Lastly, some states apply a modified consumer expectations test that incorporates risk-utility factors into the determination of a design defect. Potter v. Chi. Pneumatic Tool Co., 694 A.2d 1319, 1333 (Conn. 1997). Under the modified approach, courts typically require injured parties to prove a RAD. Aaron D. Twerski & James A. Henderson, Jr., Manufacturer’s Liability for Defective Product Designs: The Triumph of Risk-Utility, 74 Brook. L. Rev. 1061, 1100 (2009). In light of its controversy, the Restatement provides that an injured party typically relies on expert testimony to prove a RAD. Restatement (Third) of Torts: Prods. Liab. § 2 cmt. f. This burden generated considerable controversy among scholars. Philip H. Corboy, The Not-SoQuiet Revolution: Rebuilding Barriers to Jury Trial in the Proposed Restatement (Third) of Torts: Products Liability, 61 Tenn. L. Rev. 1043, 1095 (1994); see generally Note, Just What You’d Expect: Professor Henderson’s Redesign of Products Liability, 111 Harv. L. Rev. 2366, 2373 (1998) (providing that a RAD requirement “presents ‘a potentially insurmountable stumbling block’” to persons injured by defectively designed products). However, the 20 Restatement also makes clear that the RAD requirement, “like any factual element in a case,” remains an initial matter for the courts. Restatement (Third) of Torts: Prods. Liab. § 2 cmt. f. In other words: Sufficient evidence must be presented so that reasonable persons could conclude that a reasonable alternative could have been practically adopted. Assuming that a court concludes that sufficient evidence on this issue has been presented, the issue is then for the trier of fact. Id. In this case, the Crawford Court of Appeals properly determined that Ms. Bates presented sufficient evidence of a RAD when she introduced the Materials Testing Report, and this Court should affirm. Similar to Ms. Bates, injured parties routinely advance competing designs as evidence of a RAD. For instance, the court in Uniroyal Goodrich Tire Co. v. Martinez, 977 S.W.2d 328, 337 (Tex. 1998), found that injured mechanics proved a RAD by showing that competing manufacturers used safer single-strand tire beads, rather than the double-strands that exploded. The mechanics supported their showing with evidence that the defendant-manufacturer eventually adopted the single-strand model. Id. Furthermore, the Supreme Court of South Carolina determined in Branham v. Ford Motor Co., 701 S.E.2d 5, 13-14 (S.C. 2010), that an injured passenger proved a RAD by showing that an automaker had available a competing suspension system less prone to rollovers. In addition, the decision of Green v. Gen. Motors Corp., 709 A.2d 205, 214 (N.J. 1998), which involved a crash victim proved a RAD by showing that the automaker originally designed a safer roof for earlier models of the vehicle at issue. In particular, the court in Green emphasized that the manufacturer’s own testing confirmed the safety of the alternative roof. Id. at 213. Comparable to the cases with competing designs, the Materials Testing Report sufficiently establishes a RAD. The “Objective” of the Materials Testing Report illustrates that 21 Vortex knew of a stronger material before it sold Ms. Bates her graphite Splash Rower. (R. at 18.) Also, the “Test Materials” included “30 iron Splash Rowers.” (R. at 18.) Thus, Vortex designed, produced and tested an iron alternative before distribution. (R. at18-20.) Effectively, Vortex created a tangible competing design. Moreover, Vortex’s own testing showed that twenty-percent of the graphite Splash Rowers bent when subjected to alternating currents at ten mph. (R. at 19.) The iron alternatives remained straight. (R. at 19.) Based on these results, a reasonable person could conclude that Vortex had available a safer, practical RAD at the time of distribution. b. Alternatively, Ms. Bates established a design defect under a two-prong approach that applies a consumer expectations standard in circumstances that warrant an inference of a product defect. If this Court adopts a two-prong approach that applies a consumer expectations standard to circumstances that warrant an inference of product defect, then Ms. Bates establishes her defective design claim without proving a RAD. See Twerski & Henderson, supra at 1101 (providing that the Restatement complies with “two-prong states” that apply a consumer expectations standard to “res ipsa-like” failures). For example, California limited its consumer expectations prong to circumstances that permit an inference that a product failed to perform as safely as it should. Soule v. Gen. Motors Corp., 882 P.2d 298, 308 (Cal. 1994); see also McCabe v. Am. Honda Motor Co., 100 Cal. App. 4th 1111, 1125, 123 Cal. Rptr. 2d 303, 314 (2002) (reversing summary judgment because, “at a minimum,” triable issues remained as to whether the consumer expectations test applied to an airbag that failed to deploy during a headon collision). In this case, the circumstances surrounding Ms. Bates’ accident permit a jury to conclude that the Splash Rower failed to perform as safely as it should. Ordinary consumers understand that a non-mechanical, single-material product like a Splash Rower should meet 22 minimum safety standards of withstanding natural river currents. Alternatively, this Court should remand Ms. Bates’ matter with instruction to proceed under a limited two-prong approach. 2. Vortex’s failure to implement the safer iron alternative makes the Splash Rower not reasonably safe because the risks of death and great bodily harm outweigh the cost of redesigning the product. If required, Ms. Bates establishes that the safer iron alternative avoids the risk of catastrophic harm at a reasonable cost. Having shown a RAD, injured parties must also prove that the alternative design reduces or avoids the risks of harm posed by the product at issue, and that the omission of the alternative design renders that product not reasonably safe. Restatement (Third) of Torts: Prods. Liab. § 2(b) cmt. d. The Restatement adopts a risk-utility balancing test as the standard for determining whether omission of a RAD rendered the product not reasonably safe. Id. The relevant factors considered under the risk-utilities balancing test include: [T]he magnitude and probability of the foreseeable risks of harm, the instructions and warnings accompanying the product, and the nature and strength of consumer expectations regarding the product, including expectations arising from product portrayal and marketing. Id. § 2(b) cmt. F. See generally John W. Wade, On the Nature of Strict Tort Liability for Products, 44 Miss. L.J. 825, 837-38 (1973). Sufficient factors weigh heavily for Ms. Bates. As a threshold matter, the Materials Testing Report establishes the availability of a technically feasible and practical iron alternative, as Vortex actually produced thirty iron Splash Rowers for safety testing. (R. at 18.) Also, Vortex packaged the Splash Rower in camouflage and marketed its product to veterans, individuals typically portrayed as athletic, adventurous and daring. (R. at 5.) Such marketing supports a consumer expectation that the Splash Rower could withstand extreme recreational activities, let alone amateur kayaking. Lastly, Vortex sold its Splash Rower for $750. (R. at 4.) 23 Even if Vortex received standard rates for its graphite, the iron alternative costs only $187.50 more per unit. Where the foreseeable risks of product harm include drowning, hypothermia, severe trauma and exposure, a reasonable jury could conclude that avoiding these dangers justifies a higher cost. Although certain factors may lean in Vortex’s favor, such as the social utility of a recreational rowing attachment, Ms. Bates raises disputes of material fact by showing that a reasonable jury could balance a number of considerations on her side. See Camacho v. Honda Motor Co., 741 P.2d 1240, 1249 (Colo. 1987) (en banc). If this Court requires Ms. Bates to prove a RAD, she raised sufficient factual disputes under the risk-utilities balancing test to preclude summary judgment on her design defect claim. C. Vortex Failed to Provide Ms. Bates with Adequate Warnings and Instructions Regarding the Splash Rower’s Limitations, and the Risks Associated with Kayaking the Crawford River Are Nonobvious and Not Generally Known by Amputees Like Ms. Bates. Ms. Bates set forth sufficient evidence on her claim for warning defect to preclude summary judgment. A product contains defective warnings or instructions when reasonable information could have reduced or avoided the foreseeable risks of harm posed by the product, and the omission of such information renders the product not reasonably safe. Restatement (Third) of Torts: Prods. Liab. § 2(c). Inadequate instructions fail to inform users how to use a product safely, and inadequate warnings fail to alert users to the product’s risks. Id. § 2 cmt. i. Foreseeable users prove warning or instruction defects under a reasonableness standard, and multiple factors bear on the inadequacy of the information. Id. Injured parties may prove inadequacy by showing that manufacturers failed to warn of “nonobvious and not generally known risks that unavoidably inhere in using or consuming the product.” Id. However, the Restatement provides that obvious or generally known risks preclude recovery on a claim for 24 warning defect. Id. § 2 cmt. j. Here, Vortex’s warning, “FOR RECREATIONAL USE ONLY,” inadequately instructed users on safe operation and failed to warn users of the Splash Rower’s risks. Moreover, the risks associated with kayaking the Crawford River are nonobvious and not generally known by amputees like Ms. Bates. 1. Vortex provided inadequate warnings and instructions. The Splash Rower contained a warning or instruction defect because Vortex failed to inform foreseeable users of the product’s limitations. Particularly, Vortex should have known that the Splash Rower could not perform at conditions similar to the Crawford River because the Materials Testing Report indicated that graphite began to bend at currents of ten mph. See Dunne v. Wal-Mart Stores, 679 So. 2d 1034, 1038 (La. Ct. App. 1996) (finding that a manufacturer failed to warn consumers of the weight limit for a stationary exercise bike, making the product unreasonable dangerous because individuals exceeding that limit were foreseeable users). In addition, the language, “FOR RECREATIONAL USE ONLY,” fails to provide foreseeable users with any particular instruction for safe use. In contrast, a recreational trampoline provided the following: Paralysis or death can result, even if you land in the middle of the trampoline mat (bed). To reduce the chance of landing on your head or neck, do not do somersaults (flips). Only one person at a time on trampoline. Multiple jumpers increase the chances of loss of control, collision, and falling off. This can result in broken head, neck, back, or leg. This trampoline is not recommended for children under 6 years of age. Parish v. Jumpking, Inc., 719 N.W.2d 540, 546 (Iowa 2006). Accordingly, this Court should affirm the Crawford Court of Appeals’ decision to preclude summary judgment on Ms. Bates’ claim for warning or instruction defect. 25 2. The risks of kayaking were nonobvious and not generally known to amputees like Ms. Bates. The risks of kayaking down the Crawford River are nonobvious and not generally known. As a practical matter, the objective amputee does not generally know of the inherent risks of kayaking because her disability would prohibit the activity. See Sauder Custom Fabrication v. Boyd, 967 S.W.2d 349, 351 (Tex. 1998) (explaining that a manufacturer has a duty to warn of the risks for which an ordinary user is unaware). Moreover, the risks of recreational kayaking do not rise to the level of everyday knowledge that generally supports an open and obvious defense. See McMahon v. Bunn-O-Matic Corp., 150 F.3d 651, 656-57 (7th Cir. 1998) (denying the plaintiff’s failure to warn claim because the risk of spilling coffee while driving is obvious). Thus, Ms. Bates survives summary judgment on her claim for warning defect because a jury could conclude that the objective, foreseeable Splash Rower user does not generally know of the risks inherent to kayaking. For the aforementioned reasons, this Court should affirm the Crawford Court of Appeals ruling on Ms. Bates defect claims. III. MS. BATES SET FORTH SUFFICIENT EVIDENCE TO ESTABLISH THAT THE SPLASH ROWER’S MANUFACTURING, DESIGN AND WARNING DEFECTS CAUSED HER INJURIES. The Splash Rower’s manufacturing, design and warning defects substantially caused Ms. Bates’ injuries therefore making summary judgment inappropriate. This Court must also review the causation of Ms. Bates’ injuries under a de novo standard of review. According to the Restatement, the same general rules and principles that govern causation in tort matters apply in products liability cases. Restatement (Third) of Torts: Prods. Liab. § 15. First, actual cause shows “but for” the defect, the harm would not have occurred. Whitmire v. Terex Telelect, Inc., 390 F. Supp. 2d 540, 554 (E.D. Tex. 2005). Second, proximate 26 cause demonstrates that the risk of harm is the natural, foreseeable, and probable consequence of the defect. Rife v. Hitachi Constr. Mach. Co., 363 S.C. 209, 216 (Ct. App. 2005). Furthermore, a court may consider an intervening act, such as misuse, as a superseding cause and choose to relieve the defendant from liability. Perez v. VAS S.p.A., 188 Cal. App. 4th 658, 680 (2010). However, the superseding independent act must break the chain of causation and produce enough harm that it would be unfair to hold the defendant responsible. Id.; Restatement (Third) of Torts: Prods. Liab. § 15 cmt b.; Jason A. Henderson, Jr. & Aaron D. Twerski, Achieving Consensus on Defective Product Design, 83 Cornell L. Rev. 867, 877 (1998) (the “imposition of tort liability achieves corrective justice between the parties”). Nevertheless, foreseeable misuse only diminishes plaintiffs recovery if they negligently misused a product and that misuse combined with the product defect brought about their harm. Restatement (Third) of Torts: Prods. Liab. § 17 cmt. c. Sometimes misuse is so unforeseeable that, as a matter of law, there is no proximate cause. Id. § 15 (1998), Reporter's Note; Hernandez v. Tokai Corp., 2 S.W.3d 251 (Tex. 1999). Generally, causation and misuse are questions of fact for the jury. Restatement (Third) of Torts: Prods. Liab. § 15, Reporter's Note; Cardinal Health 301, Inc. v. Tyco Elec. Corp., 169 Cal. App. 4th 116, 146 (2008). Moreover, a court grants summary judgment on the issue of causation only when the defendant shows the actions were the "sole" cause of the injury sufficient to break the chain of causation, and not simply a substantial contributing factor. Derienzo v. Trek Bicycle Corp., 376 F. Supp. 2d 537, 561 (S.D.N.Y. 2005); Speller v. Sears, Roebuck & Co., 790 N.E.2d 252, 256 (N.Y. 2003). In addition, circumstantial evidence allows an inference of a product defect. Bentley, 435 Crawford at 220. Both the State of Crawford and the Restatement finds that an inference exists 27 when the harm is not "solely the result of causes other than product defect existing at the time of sale or distribution.” R. at 9; Restatement (Third) of Torts: Prods. Liab. § 3(b). Juries use circumstantial evidence in simple defect cases that do not require the use of expert evidence. Atkins v. GMC, 132 Ohio App. 3d 556, 564 (1999). Rather than negate all other possible causes of harm, a plaintiff merely needs to show the reduced likelihood of other possible causes so that a jury could reasonably determine by a preponderance of the evidence that the defendant is liable for the cause of the malfunction. Shaun T. Mian Corp., 237 S.W.3d at 863. Further, factors such as the age of the product, alteration, and misuse by the plaintiff or third parties may defeat a causal inference. Restatement (Third) of Torts: Prods. Liab. § 3 cmt. d. Here, Ms. Bates set forth sufficient evidence establish an inference of a causal connection between her injuries and the Splash Rower’s manufacturing defect because the new condition of the Splash Rower shows that the defect existed at the time it left Vortex’s control. Also, Ms. Bates raised triable issues of fact to establish that the Splash Rower’s design defect caused her injuries because Ms. Bates’ use of the Splash Rower was foreseeable. Finally, Ms. Bates established the causal connection between her injuries and the Splash Rower’s warning defect because Vortex did not provide an adequate warning for Ms. Bates to assess the potential risks involved with using the Splash Rower. A. The Splash Rower's Manufacturing and Design Defects Substantially Caused Ms. Bates’ Injuries. Ms. Bates sufficiently established a causal connection to link her injuries to both the manufacturing and design defects. A new product shows more probably than not that an inference of a manufacturing defect existed at the time the product left the manufacturer’s control. Shaun T. Mian Corp., 237 S.W.3d at 867 (a reasonable jury could infer that the new, unaltered printer which caused a fire possessed a defect at the time it left the manufacturer’s 28 hands). Likewise, normal use also enhances an inference of a manufacturing defect. McCorvey, 298 F.3d at 1258 (stating that even if the common misuse of a catheter becomes standard practice and differs from the manufacturers intended use, a casual inference of a manufacturing defect still exists). For design defects, the court in Richetta v. Stanley Fastening Systems, L.P., found that if a RAD could have prevented the injury and the plaintiff had not behaved in a manner constituting unforeseeable misuse, then the design defect claim could withstand summary judgment. Richetta v. Stanley Fastening Sys., L.P., 661 F. Supp. 2d 500, 512 (E.D. Pa. 2009). The Richetta court held that a jury could conclude that a reasonable construction worker often does not disconnect a nail gun from its air compressor when he intends to continue using it. Id. at 508. Specifically, the court noted that if the nail gun had been equipped with a RAD like a safety latch, it would have prevented the nail gun from misfiring. Id. at 512. Thus, the question of causation rested with the jury. Id. Alternatively, an old product reduces the likelihood of an inference of a manufacturing defect. Ford Motor Co. v. Ridgway, 135 S.W.3d 598, 601 (Tex. 2004). In Ford, the plaintiff’s manufacturing defect claims amounted to no more than conclusory allegations. The plaintiff sustained severe injuries when his pre-owned two-year-old truck caught fire. Id. The court concluded no causal link existed between the malfunction and the expert’s testimony which suggested that the electrical system in the truck caused the fire. Id. Furthermore, there was no proof that established a defect existed at the time it left the manufacturer. Id. Thus, the plaintiff failed to raise an issue of fact to withstand summary judgment. Id. at 602. Likewise, unforeseeable misuse breaks the chain of causation. Perez, 188 Cal. App. 4th at 685. The court in Perez found that the plaintiff misused the paper machine in two ways. First, 29 he threaded plastic through it, contrary to the manual and the machine's warnings, which stated that the machine was designed to process paper material only. Second, he failed to avoid the machine while it operated and actually used a knife to cut plastic rolls inside the machine, also contrary to the manual. Id. Thus, the plaintiff's extreme misuse broke the chain of causation. Id. However, in the present case, Ms. Bates sufficiently established a causal connection between her injuries and the defective manufacturing and design of the Splash Rower to withstand summary judgment. Furthermore, Ms. Bates' did not misuse the Splash Rower. Vortex developed the Splash Rower to “provide amputees the opportunity to participate in recreational activities." (R. at 23.) According to Crawford Regulation § 895.52, “recreational activity” means “any outdoor activity undertaken for the purpose of exercise, relaxation or pleasure” and broadly includes “water sports.” (R. at 23.) This Regulation defines the scope of what constitutes normal foreseeable use of the Splash Rower because kayaking is both a water sport and a recreational activity. A reasonable jury could also come to the same conclusion. Also, Ms. Bates never abused the Splash Rower. Rather than attempt to kayak in a fast and dangerous manner, she slowed the kayak down by dunking her paddle deep into the water. (R. at 5). If a kayaker starts to struggle with their kayak, they will commonly try to maneuver it in a way that allows them to regain control. Similar to the common misuse reasoning in McCorvey, even if Vortex argues that Ms. Bates' conduct constitutes misuse, the manner which Ms. Bates tried to regain control of her kayak is so common that Ms. Bates' behavior actually amounts to normal use. On grounds of fairness, a court should hold Vortex accountable for Ms. Bates’ injuries because she used the Splash Rower in a normal and foreseeable manner. Moreover, Ms. Bates proved a causal inference of a defect because the Splash Rower would not have malfunctioned “but for” a defect. Like the printer in Shaun T. Mian Corp., the 30 Splash Rower was a new product that Ms. Bates first used on June 22, 2010. (R. at 5). Thus, the Splash Rower was in the same basic condition as when it left Vortex’s control. The manufacturing defect more likely than not caused her injuries. Unlike the proof presented in Ford Motor Co., the evidence here does more than simply raise the possibility that the manufacturing defect could have caused her injuries. Rather, the evidence establishes that the manufacturing defect substantially caused Ms. Bates’ ejection from her kayak, causing her to smash into a cluster of rocks. Further, Ms. Bates’ injuries are the natural and probable cause of the defect. It is reasonably foreseeable that the risk of harm created when the Splash Rower suddenly snapped during kayaking would substantially affect an amputee like Ms. Bates. At a minimum, Ms. Bates sufficiently raised a triable issue of fact regarding an inference of a causal connection to preclude summary judgment. Ms. Bates also proved a causal link between the design defect and her injuries. First, the Splash Rower’s RAD is stronger than the graphite design. A jury could reasonably find that the use of graphite instead of iron made the Splash Rower unreasonably dangerous and that “but for” the design defect, Ms. Bates would not have been harmed. Second, her injuries are also the natural and probable consequence of the design defect. It is reasonably foreseeable that the risk of harm is great created when the Splash Rower suddenly snapped is substantial to a kayaking amputee. Thus, summary judgment is inappropriate. B. The Splash Rower's Warning Defect Substantially Caused Ms. Bates’ Injuries. The Splash Rower’s warning defect substantially caused Ms. Bates’ injuries because the warning label did not contain adequate information to caution Ms. Bates of the risks. A failure to warn claim asserts that had a warning been given, the injuries would not have occurred. Stringer v. Nat'l Football League, 749 F. Supp. 2d 680, 690 (S.D. Ohio 2009). Thus, 31 a court requires plaintiffs to allege that they would have acted differently had the manufacturer provided adequate warnings. Id. at 691. A manufacturer must be liable for injuries caused by their failure to warn against reasonably foreseeable unintended use or misuse of the product. Derienzo, 376 F. Supp. 2d at 567. Generally, the adequacy of a warning is a question of fact for the jury. Id. At the summary judgment stage, the plaintiff does not have the burden to establish that an adequate warning would have prevented the injuries. Id. The court in Derienzo, 376 F. Supp. 2d at 570, found that the plaintiff's failure to warn claim against a mountain bike manufacturer withstood summary judgment. In that case, the plaintiff alleged that his injury from attempting to land a jump on his bike was caused by the defendant's failure to warn against such use. The court found that jumping was not a misuse of the bike because jumping was an "entirely foreseeable" and "expected use of a mountain bike” and even the defendant’s catalogue marketed pictures of an airborne biker. Id at 569. In addition, the fact that the plaintiff conceded that he had not read the warning did not defeat his claim. The court reasoned that a jury could find that the "realities of society" might have resulted in the plaintiff's friends informing him not to jump had an adequate warning against jumping been included with the bike. Id. at 570. Therefore, summary judgment for the defendant was denied. Id. Alternatively, the court in Colon v. BIC USA, Inc., 199 F. Supp. 2d 53, 95 (S.D.N.Y. 2001), found that the plaintiff had failed to establish that the warning defect proximately caused her son’s injuries. In that case, the plaintiff sued the defendant after her child severely injured himself when he ignited his shirt with a butane cigarette lighter. The plaintiff alleged that the non-permanent warning label "Keep Away from Children" had been removed and that this constituted a warning defect. Id. at 92. The plaintiff failed to establish a causal link between the 32 defect and her son’s injuries. Id. at 95. Based on her testimony, she specifically warned her child against using the lighter. As a result, the court determined that the alleged defect did not substantially cause the injuries because the plaintiff’s conduct would have remained unchanged regardless of the existence of a warning defect. Id. at 92-93. Thus, the court dismissed the plaintiff's failure to warn claim. Id. at 95. In the present case, Ms. Bates sufficiently established that the Splash Rower’s warning defect substantially caused her injuries. The only warning that accompanied the Splash Rower was a slip of paper with the words, "FOR RECREATIONAL USE ONLY" written in bold red letters. (R. at 5). However, this warning failed to specifically articulate predictive information. At best, the warning is ambiguous and fails to define "recreational use" or to distinguish between "recreational use" and "professional use." According to the Crawford legislature's definition of "recreational," this term includes all "water sports." (R. at 23). This broad definition shows that kayaking is a reasonably foreseeable use of the Splash Rower and that the Splash Rower substantially caused Ms. Bates’ injuries. Vortex had a duty to warn against the risks associated with any foreseeable use of the Splash Rower. It also demonstrates that kayaking is a normal foreseeable use of the Splash Rower and not a misuse that would break the chain of causation. The record is silent as to any proof that Ms. Bates maneuvered the Splash Rower beyond its normal use of kayaking. In fact, Ms. Bates slowed the kayak down and carefully maneuvered around rocks and branches until the Splash Rower suddenly snapped. (R. at 5). Therefore, for fairness purposes, because Ms. Bates used the Splash Rower in a normal foreseeable use and did not misuse it, liability rests with Vortex. In addition, had an adequate warning been provided, Ms. Bates' would have at least understood the risks associated with kayaking. The Splash Rower’s warning “FOR 33 RECREATIONAL USE ONLY” never warned Ms. Bates not to kayak. Consequently, her kayaking trip on June 22, 2010 was not a misuse. Unlike the plaintiff in Colon ex rel. Molina, an adequate warning would have most likely changed her behavior. “But for” this warning defect, Ms. Bates would not have been injured. Ms. Bates' injuries are also a natural and probable consequence of the warning defect. Thus, Ms. Bates has raised an issue of triable fact that could lead a jury to conclude that the warning defect substantially caused her injuries. Summary judgment is therefore not appropriate. In conclusion, Ms. Bates set forth sufficient evidence to establish an causal inference between her injuries and the manufacturing defect because the new condition of the Splash Rower shows that the defect existed at the time it left Vortex’s control. Second, Ms. Bates established that the Splash Rower’s design defect substantially caused her injuries because Ms. Bates’ use of the Splash Rower was normal and foreseeable. Ms. Bates never abused the Splash Rower when she used it. Finally, Ms. Bates established the causal connection between her injuries and the Splash Rower’s warning defect because Vortex did not provide an adequate warning for Ms. Bates to assess the potential risks involved with using the Splash Rower. Therefore, Ms. Bates has raised issues of triable fact that a jury could assess and appropriately conclude that the manufacturing, design and warning defects of the Splash Rower substantially caused Ms. Bates’ injuries. This Court should thus affirm the decision of the Crawford Court of Appeals. CONCLUSION Wherefore, Respondent respectfully moves this Court to affirm the judgment of the Crawford Court of Appeals for the Fifth District of Wells County. 34
