Rawlings Rough Draft, Family Rights Article 8/25/09, Page 1 Child Protective Services and Fundamental Familial Rights ROUGH DRAFT OF MATERIALS STUDENTS Justice Leah Ward Sears Class UGA Law School Introduction: The Right to Family Integrity and Privacy The law is clear and settled that there is a fundamental right to family integrity and privacy older than the Constitution itself,1 a “private realm of family life which the state cannot enter.”2 There is also no doubt that this fundamental freedom protects families from unwarranted intrusion by government child protective service agencies.3 Indeed, as the Supreme Court held in Troxel v. Granville:4 “[S]o long as a parent adequately cares for his or her children (i.e., is fit), there will normally be no reason for the State to inject itself into the private realm of the family to further question the ability of that parent to make the best decisions concerning the rearing of that parent's children.” Failure to observe that “zone of privacy” exposes the state to a claim that it has violated the family’s Fourth,5 Fifth,6 and Fourteenth7 amendment rights under the Constitution. Troxel and its precedental ancestors and progeny make clear that the state cannot forcibly separate parent and child for any significant period of time without a court hearing,8 clear and convincing evidence of parental unfitness,9 and provision of counsel to the parent.10 But, as many lower courts have held, none of these protections prohibits the state from pursuing its responsibility to protect children from abuse and neglect, and “[t]he right to familial integrity . . . does not include a right to remain free from child abuse investigations.”11 So while the “so long” part of the Troxel formula is clear, the question not answered by that or other Supreme Court decisions is what happens when the claim is made that the parent is not fit. The following questions often arise: Under what conditions may the state intervene to investigate whether the parent is unfit, and what actions may it take during that investigation? 1 Griswold v.

Rawlings Rough Draft, Family Rights Article 8/25/09, Page 2 What evidence is necessary to justify state intervention in the family short of separating parent and child? What is the threshold level of state intervention at which the protections of Troxel, Stanley, et al. kick in? These questions are especially pressing for child protective service agencies as well as welfare attorneys and judges. Increasingly, child protective practice nationwide emphasizes less reliance on foster care and expanded use of alternative response systems, family preservation programs and voluntary “safety plans” and “safety resources.” These practices are intended to be less intrusive and emphasize cooperation between the agency and the family. But because the agency’s intervention is backed by the power of the government, some have expressed concern that these more “family-centered” practices can improperly intrude on family rights without extending to families the due process protections and court oversight they would otherwise have if the agency took the additional step of placing the child in foster care.12 Examining current social work and child protective service practices within the state of Georgia, this article attempts to determine when child protective agency intervention reaches a level at which procedural due process protections apply and how one might properly balance the state’s interest in protecting children against the family’s interest in freedom from government interference. Current Child Protective Services Policy and Practice The “traditional” model of child protective services practice suggests that when the agency receives a report of abuse or neglect, it investigates and, if it believes intervention is warranted, the juvenile or family court is called and a petition alleging deprivation or dependency is filed. While the case decisions are somewhat inconsistent, the general rule is that the state may not separate a child from his or her family without a court order or reasonable evidence showing the child is in imminent danger or harm or abuse.13 In reliance on that model, states and the federal government have enacted numerous protections for parents and children subjected to interventions by government child protective service agencies. In Georgia, the juvenile court is the court of “exclusive jurisdiction” for children alleged to be without a fit parent or guardian.14 If a child is removed due to allegations that he or she is deprived, the court must hold a preliminary hearing on the issue within 72 hours.15 The parties in court have the right to attorneys, See, e.g., Sinden, “Won't Mom Cooperate?: A Critique of Informality in Child Welfare Proceedings,” 11 Yale J.L & Feminism 339 (1998); Pearson, “Cooperate Or We'll Take Your Child: The Parents' Fictional Voluntary Separation Decision And A Proposal For Change,” 65 Tenn. L. Rev. 835 (1998). 13 See, e.g., Tenenbaum v. Williams, , 193 F.3d 581, 594 (2d Cir. 1999). 14 OCGA § 15-11-28(a)(1). 15 OCGA § 15-11-49(c)(3). 12 © Tom C. Rawlings Rough Draft, Family Rights Article 8/25/09, Page 3 including free attorneys if they are indigent.16 The parties are have the rights to present evidence and cross-examine witnesses17 and rights of the children in such cases include the right to a guardian ad litem.18 Children may not be separated from their parent or guardian for any significant length of time without a court finding, by clear and convincing evidence, that the parent is unfit and that the parent’s lack of fitness is harmful to the child.19 These statutory and judicially-created rights ensure the child and the family are afforded appropriate substantive and procedural due process when the state’s child protective service agency intervenes in their lives. Increasingly, however, children are neither taken into foster care nor are families brought before the court to answer the agency’s charges. In Georgia, for example, foster care rolls dropped by 40% between 2004 and 2009 based in large part on concerted efforts to use alternative response mechanisms and family preservation programs. The agency’s reliance on the juvenile court dropped in response. Between fiscal years 2007 and 2009 in one suburban metropolitan county, dependency case filings dropped by 44%.20 Over half of child maltreatment reports are now handled through an alternative response known as “diversion,” whereby families are referred to outside services.21 Among those family preservation practices are the use of “safety plans” and “safety resources.” A safety plan is a voluntary agreement by the parent to take specific steps to keep the child safe or refrain from doing something that is endangering the child. These plans are sometimes as simple as an agreement to place childproof locks on a cabinet, but they may be as complicated as ensuring that all visitation between a child and parent is supervised by an agency-approved adult. A “safety resource” plan goes even further. In it, the parent agrees to place the child with a friend, neighbor, or relative until a CPS investigation is complete or until the problems that resulted in CPS involvement are resolved. Sometimes the child remains in the home with an approved parent or relative while the parent accused of neglect or abuse moves out. Whether these safety plan and safety resource agreements are truly “voluntary” has been the subject of both scholarly debate22 and extensive litigation.23 This article will 16 OCGA § 15-11-6.

This article, rather, inquires into the conditions under which the government can justifiably request or require a parent or child to engage with the Department’s investigative or service efforts absent a court order. CPS Investigations and Fundamental Rights: Some General Rules The Fourth Amendment protects individuals from unreasonable searches or seizures of their person or property. In the context of the police officer’s interaction with a suspected criminal, the Supreme Court has passed on the facts and law of so many police-citizen interactions that the rules are fairly clear. The Fourth Amendment does not prohibit a police officer from knocking on the front door of a house and asking whether the homeowner would mind answering questions. A police officer’s stop of a vehicle or brief detention, questioning, and search of an individual, however, requires justification: a reasonable, articulable suspicion, based on facts, that the individual has committed or is committing a crime.24 And a police officer cannot enter a person’s home without consent or a warrant unless probable cause, combined with exigent circumstances, justify warrantless entry.25 Exigent circumstances are, generally, limited to situations in which there is imminent threat to a person inside the home or, as one Circuit holds, “.circumstances that would cause a reasonable person to believe that entry was necessary to prevent . . . destruction of relevant evidence, the escape of the suspect, or some other consequence improperly frustrating legitimate law enforcement efforts.”26 While less often the focus of court inquiry, child protective services investigations and actions are often evaluated using language similar to that used in Fourth Amendment analyses.27 Such similarity is to be expected. The Fourth Amendment preserves the right to be free from warrantless searches by the government, without limiting that right to one type of official.28 The Supreme Court has itself described the Fourth and Fifth Amendment as “protection against all governmental invasions `of the sanctity of a man's home and the privacies of life’.”29 Numerous federal cases have questioned whether child protective services investigations were supported by “reasonable suspicion”30 or by “reasonable and articulable evidence giving rise to a reasonable suspicion that a child has been abused or is in imminent danger of abuse.”31 Others have analyzed whether a 24 Terry v. Ohio, 392 U.S. 1. Payton v. New York, 445 U.S. 573, 586 (U.S. 1980). 26 United States v. Brooks, 367 F.3d 1128, 1135 (9th Cir. Cal. 2004). 27 Wooley v.

Pa. 1997) 25 © Tom C. Rawlings Rough Draft, Family Rights Article 8/25/09, Page 5 warrantless intrusion into a home for purposes of a child protective services investigation was justified by “exigent circumstances.”32 As noted above, the propriety of child protective service investigations and interventions are also analyzed pursuant to Fifth and Fourteenth Amendment interests of the family in privacy and familial integrity. Thus, in Gomes v. Wood, the 10th Circuit Court of Appeals emphasized that in ordinary circumstances due process requires the parents receive prior notice and a hearing.33 In determining whether intervention without a court order was warranted, however, that court and others as a general rule fall back on Fourth Amendment concepts of whether the “search” or “seizure” of the child was reasonable and justified by the circumstances. In the following sections we examine how different “levels” of familial intrusion by child protective service agencies are addressed by the Courts. Searches of and Interviews With Children Child protective service agency policies often call for children who are suspected victims of abuse to be interviewed at the first possible opportunity. These policies also often call for children to be undressed and examined for bruises. Such contacts without parental permission raise serious Fourth and Fourteenth Amendment issues. Interviewing a child at a school without parental permission raises both Fourth Amendment and family liberty interests, and the time, place, and manner of the interview can impact its constitutionality. For example, an interview of a child at a private school may violate the Fourth Amendment, while the same interview of a child at a public school may not. In Doe v. Heck, 34 parents sued after child protective services workers, accompanied by police, interviewed their 11 year-old son at his private school after receiving complaints that children there were subjected to excessive corporal punishment. The social workers interviewed the child over the school’s objections about punishments he received at school and at home. The 7th Circuit held that the child’s and family’s Fourth Amendment rights and privacy rights had been violated. To determine whether the interview was inappropriate, the Court looked to the parents’ subjective and objective expectations of privacy for their child while at the school. The Court held: “[W]hile [the child. may not have exhibited a subjective expectation of privacy in [the private school’s] premises, we have held that such a showing is unnecessary when the search or seizure at issue is of a young child,” the Court wrote. And by “entrusting him to the care of the school's 32 Gates v. Tex. Dept. Prot. and Reg. Svcs., 537 F.3d 404 (5th Cir. 2008). Gomes v. Wood, 451 F3d 1122 (2006). 34 327 F3d 492 (7th Cir. 2003) 33 © Tom C. Rawlings Rough Draft, Family Rights Article 8/25/09, Page 6 officials in loco parentis, the [parents] manifested a subjective expectation of privacy in the premises of the school.”35 The 7th Circuit reaffirmed Heck’s holding in the context of physical examinations for bruises in Michael C. v. Gresbach.36 In the public school setting, child protective service workers are likely to have more leeway to interview students and to examine them, as the parents may not have as high an expectation of privacy in a public school setting as in a private. Even in the public school setting, child examinations that are overly intrusive or that are not sufficiently supported by evidence may violate the rights of parent or child. Few cases to date, however, have given clear guidance on how courts reviewing interviews and searches of children in the public school setting should balance the child’s or family’s privacy rights against the state’s obligations to investigate abuse. In Darryl H. v. Coler,37 the appellate court refused to dig into the details of the issue when determining whether a preliminary injunction should issue barring a child protection agency from performing searches of children at school. The Court did, however, caution that intrusive examinations of children that exposed their private areas were suspect, and that while a physical examination of a young or nonverbal child might be considered reasonable, a similar search of an older child who can communicate might not. As the court noted: The test of reasonableness under the Fourth Amendment is not capable of precise definition or mechanical application. In each case it requires a balancing of the need for the particular search against the invasion of personal rights that the search entails. Courts must consider the scope of the particular intrusion, the manner in which it is conducted, the justification for initiating it, and the place in which it is conducted.38 In Coler, the Court refused at that stage of the litigation to impose a probable cause or warrant requirement on interviews with or physical examinations of children in the public school setting. Other courts have taken a harder stance on these issues, especially when the intrusion is more significant. Even where an examination or questioning of the child might occur in a place where there is no family expectation of privacy, there are limits to what the agency can require of the child without parental permission. Thus, the Second Circuit has held a child protection agency violated the rights of parents of a child with a broken leg when it independently ordered the hospital to perform additional x-rays on the 35 Id. at 512; accord Word of Faith Fellowship, Inc. v.

Rawlings Rough Draft, Family Rights Article 8/25/09, Page 7 child to check for prior abusive injuries.39 Likewise, New York officials violated a family’s integrity rights when, without a court order, they took the daughter from school to a gynecologist to be examined for possible sexual abuse.40 In Roe v. Tex. Dep't of Protective & Regulatory Servs.,41 the Fifth Circuit held that a body cavity search of a suspected child victim of sexual abuse is not permissible absent a court order, parental consent, or probable cause. Perhaps the most instructive decision comes not from litigation over a child abuse investigation but from the Supreme Court’s recent opinion in Safford Unified School District #1 v. Redding,42 where the Court reiterated that an examination of a child in a public school be “reasonably related in scope to the circumstances which justified the interference” and “not excessively intrusive in light of the age and sex of the student and the nature of the [investigation]."43 These cases clarify that the state may well violate a family’s privacy interests when it interviews or examines a child without parental permission. Whether the state is justified may depend on the facts. Did the parents send their child to a public school, or did they seek less government scrutiny by choosing a private school? Were officials viewing parts of the child’s body that his or her friends might see or requiring the child to expose private areas? Did the activities occur on a school campus, or did officials take the child elsewhere without telling the parents? Is the child old enough to make his or her own decisions independent of the family, or is the child so young that the only way to determine whether abuse occurred to inspect the child? Entry into Homes The Courts have most strongly supported the right to family privacy and integrity when child protective service workers without a warrant or court order have attempted to enter the family home in their investigation efforts. The recent Fifth Circuit case of Gates v. Texas. Dep't of Protective & Regulatory Services44 presents a prime example. There, social workers accompanied by police insisted on entering the Gates’ home to interview their children as part of a child abuse investigation. The Court began by noting that "physical entry of the home is the chief evil against which the Fourth Amendment is directed . . . . Pursuant to our Fourth Amendment law, warrantless searches of a person's home are presumptively unreasonable unless the person consents, or unless probable cause and exigent circumstances justify the search."45 Finding no consent, the Court also 39 Van Emrik v.

Rawlings Rough Draft, Family Rights Article 8/25/09, Page 8 rejected any suggestion that social workers were justified in entering by “exigent circumstances”: “Turning to the facts of this case, we agree with the Gateses that there were no exigent circumstances present at the time of the defendants' initial entry into the Gateses' house that would have permitted the warrantless intrusion. First, . . .the alleged abuser, was not at home, so there was no immediate danger to the children. Also, at that time, TDPRS was not aware of any allegations that Gary had abused any of his children besides Travis, other than his unusual discipline methods. We further note that none of the TDPRS employees treated these interviews as emergencies. . . . . [T]the interviews conducted at the Gateses' home were routine, nonemergency interviews. In fact, the TDPRS employees went to lunch after interviewing [other children in the family] at school without taking any emergency measures. . . . Thus, at the time the individual defendants approached the house, the only evidence of danger to the Gates children was a one-time incident involving only [one child] and the questionable discipline methods. These facts do not give rise to an `immediate danger’ supporting a warrantless entry into the Gateses' house. Indeed, the stated purpose of entering the house was to interview the children, not to guard them against some sort of immediate danger.” Other courts have expressed the view, laid out in Gates, that the need to quickly investigate a case, or general concern over a child’s safety do not constitute “exigent circumstances” under the law.46 The courts are fairly in agreement that, absent an emergency, the Fourth Amendment prohibits warrantless entry into a home even when the purposes of that entry are to determine whether a child has suffered abuse. Safety Plans Current CPS practices often involve encouraging a parent to voluntarily agree pursuant to a “safety plan” to take some action that will reduce the risk of harm to a child pending the agency’s investigation or the institution of appropriate family services. As noted above, some critics complain that these interventions are not truly voluntary. In one noted case, the Court went further and questioned whether, under the circumstances, the agency was even justified by the circumstances in requiring the father to move out of the home temporarily. Croft v. Westmoreland County Children and Youth Services, a Third Circuit case, stemmed from an ultimatum given by a social worker that an accused father move out of 46 Good v. Dauphin County Social Services for Children & Youth, 891 F.2d 1087, 1096 (3d Cir. Pa. 1989); Calabretta v. Floyd, 189 F.3d 808, 817 (9th Cir. Cal. 1999);. [more cites?] © Tom C. Rawlings Rough Draft, Family Rights Article 8/25/09, Page 9 his home pending a child sexual abuse investigation or lose the child to foster care. In Croft, the evidence on which the worker relied was an anonymous tip that the father was sexually abusing the child and that the child “left the house naked at night and went to a neighbor’s house and told the neighbors she was sleeping with mommy and daddy.” When interviewed, the father confirmed only that the child on one occasion walked out of their house at night and went the nanny’s house next door. The child confirmed that event and “gave no indication that she had ever been sexually abused.” While the social worker could not determine that abuse occurred, she believed that some inconsistencies in the statements of the father and mother raised “red flags.” Her agency’s policy was that if the social worker could not determine whether abuse occurred, she must attempt to separate the child and accused pending the investigation. The Court held that an anonymous tip and minor inconsistencies in the parents’ statements did not give the social worker cause to demand that the father leave the home. The agency’s action was unwarranted, the Court held, because the social worker “lacked objectively reasonable grounds to believe the child had been sexually abused or was in imminent danger of sexual abuse.”47 “An anonymous tip may justify investigation but will not provide reasonable grounds for removal of a family member absent independent, articulable criteria of reliability; and certainly not when all evidence is to the contrary,” the Court held.48 Safety plans may also be subject to scrutiny on the basis that they are overly broad. In Ault v. Speicher,49 the district court relied on binding precedent to declare appropriate a safety plan that required a mother to leave her children with the grandparents. It cautioned, however, that the plan -- which she was told would be in place until the Department agreed otherwise and which severely limited her visitation with the children – was suspect because it was not an “efficient” or “properly tailored” means to the government’s justified end of protecting the children. Other Courts have held that given sufficient evidence it is appropriate to ask a parent to vacate the home pending an investigation. An exemplar here is Gottlieb v. County of Orange50, a Second Circuit case in which the agency asked the parent accused of child sexual abuse to remove himself from the home pending a 90-day investigation rather than requiring the agency to seek a Court order. The Court had no problem validating this arrangement despite the father’s argument that the agency was required first to seek a Court order. It held: “When the agency takes the child into its own custody, causing a complete uprooting, it must promptly seek court approval. There are sound policy reasons for not imposing such a requirement automatically when, in preference to having the child removed, the parent has temporarily agreed to leave the home.” 47 Croft, 103 F.3d at 1127 Cite. 49 2009 U.S. Dist. LEXIS 23495 (S.D. Ill. 2009) 50 84 F.3d 511, 522 (2d Cir. N.Y. 1996) 48 © Tom C. Rawlings Rough Draft, Family Rights Article 8/25/09, Page 10 Such reasons, the Court added, include the benefits of allowing the parties to work together and take the time to resolve the matter themselves before going to Court.51 Otherwise, the requirement that a hearing be held in three days might, in essence, “gum up the works” for all parties involved. Such a policy of allowing the parents and the agency “wiggle room” to determine how best to proceed appears to have been the basis for the Seventh Circuit decision in Dupuy v. Samuels,52 in which the Court rejected an outright ban on the use of safety plans. Taken together, these cases suggest that an agency with reasonable cause to believe a child is at risk may strongly encourage a parent to agree voluntarily to temporarily place the children elsewhere, for one parent to leave the home, or to take measures that will ensure the child is not subjected to harm. However, a safety plan must be justified by reasonable evidence, and it must be narrowly tailored so as to accomplish the state’s appropriate purposes without overly burdening the family’s liberty interests. When Are Family Rights Infringed? Although child protective services investigations are intrusive, not every imposition on a family’s integrity amounts to a violation of these fundamental rights. As the Court noted in Croft,53 “[t]he right to familial integrity . . . does not include a right to remain free from child abuse investigations.” Where a social worker wrongly told a noncustodial father he could not visit with his child pending an abuse investigation, and the only “loss” to the father during that time was one day’s visit, the court in Terry v. Richardson54 suggested the violation insufficient to be actionable. “It is enough to say that the deprivation is minor compared with the state's substantial interest in protecting children . . . from sexual abuse,” the Court wrote. “This disparity affects what process is due. Where the loss is small, due process does not require elaborate procedures in advance.”55 Other courts have similarly held that child protection agencies have more “leeway” in imposing on parental visitation rights than when they seek to remove a child from the parent’s custody.56 The Balancing Test Perhaps no better summation can be given of the rules governing child protective services intervention than that described by the Court in Doe v. Heck:57 51 Id. Supra n. ___ 53 Supra n. 11. 54 346 F.3d 781, 787 (7th Cir. Ill. 2003) 55 346 F.3d at 787. 56 Brittain v. Hansen, 451 F.3d 982, 989-990 (9th Cir. Cal. 2006). 57 Supra, 327 F.3d at 520 (internal citations and punctuation omitted). 52 © Tom C. Rawlings Rough Draft, Family Rights Article 8/25/09, Page 11 Therefore, when analyzing a familial relations claim, a balance must be reached between the fundamental right to the family unit and the state's interest in protecting children from abuse.In weighing these competing interests, we do so under the same reasonableness test used to evaluate Fourth Amendment claims, under which we are required to consider: (1) the nature of the privacy interest upon which the action taken by the State intrudes; (2) the character of the intrusion that is complained of; (3) the nature and immediacy of the governmental concern at issue; and (4) the efficacy of the means employed by the government for meeting this concern. This analytical framework allows courts to determine whether the governmental action taken was justified at its inception, and reasonably related in scope to the circumstances which allegedly justified the interference in the first place. Thus, although child welfare caseworkers may investigate allegations of child abuse without violating parents' constitutional right to familial relations, they may not do so arbitrarily.”
