Manuela Espinosa TOPIC: Amending Parties after the Limitations Period CASE NAME: Krupski v. Costa Crociere S.P.A. ISSUE: Whether relation back under Rule 15(c) depends on the amending party’s knowledge or timeliness. HOLDING: No. Rule 15(c) of the Federal Rules of Civil Procedure allows an amended pleading to relate back to the date of the original pleading if: (1) the claim against the new defendant involves the same conduct, transaction, or occurrence set forth in the original complaint; (2) the new defendant received notice of the lawsuit such that it would not be prejudiced by being named; and (3) the new defendant knew or should have known that it would have been sued but for the plaintiff’s mistake about its identity. RULE: Relation back under Rule 15(c) does not depend on the amending party’s knowledge or timeliness. FACTS: On February 21, 2007, Wanda Krupski (plaintiff) was injured while on board a cruise ship operated by Costa Crociere S.p.A. (Costa Crociere) (defendant). Krupski’s ticket listed Costa Cruise on the front of the ticket but identified Costa Crociere as the carrier on the back of the ticket. On February 1, 2008, Krupski brought a suit in negligence against Costa Cruise. The statute of limitations expired three weeks later. After the expiration of the statute of limitations, Costa Cruise alerted Krupski to Costa Crociere’s identity as the proper defendant on several different occasions. Costa Cruise ultimately moved for summary judgment on grounds that it was not the proper defendant. Krupski cross-moved to amend her complaint to add Costa Crociere. The Federal District Court for the Southern District of Florida (District Court) denied Costa Cruise’s motion for summary judgment and granted Krupski’s motion for leave to amend. Krupski and Costa Cruise then stipulated to dismiss Costa Cruise from the action. Krupski filed an amended complaint against Costa Crociere on July 11, 2008. Costa Crociere thereafter filed a motion to dismiss, arguing that Krupski’s amended complaint did not relate back to the date of her original complaint and that, therefore, Krupski’s suit was Manuela Espinosa outside the statute of limitations. The District Court granted the motion to dismiss. The Court of Appeals for the Eleventh Circuit affirmed. REASONING: Here, the Court of Appeals refused to allow relation back in part because Krupski knew or should have known of Costa Crociere’s identity and thus, her decision to sue Costa Cruises was deliberate and not a mistake. However, the proper inquiry is what the new defendant knew or should have known, not what the plaintiff knew or should have known. Specifically, the question is whether Costa Crociere knew or should have known that, but for a mistake, it would have been named in the lawsuit. Costa Crociere argues that because Krupski was aware of Costa Crociere’s existence, Krupski’s decision to name Costa Cruises was not a mistake. However, simply being aware of two parties does not necessarily mean that a plaintiff cannot make a mistake in naming the wrong party. For instance, a plaintiff could be aware of the two different parties but still be mistaken as to the specific roles played by each party. The Court of Appeals also based its decision to deny relation back on Krupski’s considerable delay in moving to amend. However, Rule 15(c) does not provide for undue delay as a basis for denying relation back and, in fact, mandates relation back once its requirements are met. Here, Krupski’s complaint demonstrates confusion as to which company owned and operated the cruise ship Krupski was injured on. Costa Crociere, which had constructive notice of Krupski’s complaint, should have known that this confusion on Krupski’s part had resulted in Krupski’s mistakenly naming Costa Cruises as the defendant. These facts demonstrate that Costa Crociere knew or should have known that, but for Krupski’s mistake, it would have been named in the suit. Therefore, relation back is mandated. The judgment of the Court of Appeals is reversed and the case is remanded for further proceedings.
