¶ 1 This case requires us to determine whether and under what circumstances a child placed in a foster care facility may bring an action based upon 42 U.S.C. § 1983 (2003) against individual state workers for violating the foster child’s substantive due process rights under the United States Constitution. We exercise jurisdiction pursuant to Article VI, Section 5.3 of the Arizona Constitution, Arizona Revised Statutes (A.R.S.) § 12-120.24 (2003), and Rule 23 of the Arizona Rules of Civil Appellate Procedure.
I.
A.
¶2 This case arises out of the alleged sexual assault of twelve-year-old Michael L. by two minors held at the Alice Peterson Shelter (the Shelter), a foster care facility. The assaults reportedly occurred over the course of four months in 1996 and 1997, after Claudette Washington, Michael’s intake social worker, had arranged for Michael’s placement at the Shelter following his removal from his home because of unsanitary conditions. In mid-December 1996, Parthenia Gibson became Michael’s social worker. Shirley Lewis supervised both Washington and Gibson throughout Michael’s placement at the Shelter.
¶3 Cheryl Weatherford, acting as Michael’s guardian ad litem, sued the State of Arizona, Washington, Gibson, and Lewis for negligence and for depriving Michael of his constitutional rights, in violation of § 1983. During summary judgment proceedings, Washington, Gibson, and Lewis did not dispute that, acting in their capacity as social workers, they failed to comply with various agency requirements, including failures to timely complete an initial case plan, to assess Michael’s needs and his compatibility with other Shelter residents, and to visit the Shelter within twenty-four hours of Michael’s placement. In addition, they did not dispute that they made only two of the sixteen required weekly supervised visits to the Shelter between November 14, 1996, and the disclosure of the alleged sexual abuse on March 4,1997.
¶ 4 The superior court nonetheless granted summary judgment in favor of each of the defendants based upon qualified immunity, 42 U.S.C. § 1983, and protective services immunity, A.R.S. § 8-805.A (2001). The court of appeals reversed the order dismissing Weatherford’s negligence and § 1983 claims.
Weatherford v. State,
B.
¶ 5 Section 1983 imposes liability on one who, under color of law, deprives a person of any “rights, privileges, or immunities secured by the Constitution and laws.” 42 U.S.C. § 1983. Government officials performing discretionary functions, however, receive qualified immunity from § 1983 actions unless their conduct violated a clearly established constitutional or federal statutory
¶ 6 To overcome the social workers’ qualified immunity defense, Weatherford bears the initial burden of proving a violation of a clearly established constitutional or statutory right. A right is “clearly established” when “[t]he contours of the right [are] sufficiently clear that a reasonable official would understand that what he is doing violates that right.”
Anderson v. Creighton,
¶ 7 At oral argument, the social workers conceded that a foster child’s substantive due process right to reasonable safety while in foster care was clearly established in 1996.
2
As a result, the issue before this court is whether the social workers’ conduct, viewed in the light most favorable to Weatherford, could subject them to individual liability under § 1983. Determining the appropriate standard by which to measure the challenged conduct presents a question of substantive federal law.
Martinez v. California,
C.
¶ 8 In interpreting substantive federal law, state courts look first to decisions of the United States Supreme Court. Although only a decision of the Supreme Court binds a state court on a substantive federal issue, a number of state supreme courts have elected to follow, as far as reasonably possible, their federal circuits’ decisions on questions of substantive federal law.
See Littlefield v. Dep’t of Human Seros.,
[E]ven though only a decision of the Supreme Court of the United States is the supreme law of the land on a federal issue, nevertheless, in the interests of existing harmonious federal-state relationships, it is a wise policy that a state court of last resort accept, so far as reasonably possible, a decision of its federal circuit court on such a federal question.
.
Littlefield,
¶ 9 We agree that, although state courts are not bound by decisions of federal circuit courts, we may choose to follow substantive decisions of the Ninth Circuit Court of Appeals, recognizing that doing so furthers federal-state court relationships. In addition, consistent decisions among federal and state courts further predictability and stability of the law. Therefore, if the Ninth Circuit has announced a clear rule on an issue of substantive federal statutory law and if the rule appears just, we will look first to the Ninth Circuit rule in interpreting substantive federal statutory law.
II.
¶ 10 The gravamen of Weatherford’s § 1983 complaint is the claim that the social workers violated Michael’s substantive due process rights. In determining the appropriate standard for imposing § 1983 liability, we first acknowledge that standards of state tort law do not apply; rather, the question is whether defendants violated Michael’s federal constitutional rights. “Our Constitution deals with the large concerns of the governors and the governed, but it does not purport to supplant traditional tort law in laying down rules of conduct to regulate liability for injuries that attend living together in society.”
Daniels v. Williams,
¶ 11 The touchstone of substantive due pi’ocess is protection against government power arbitrarily and oppressively exercised.
Id.
at 331-32,
¶ 12 Neither the Supreme Court nor the Ninth Circuit has clearly defined when executive conduct becomes “arbitrary in the constitutional sense” so as to impose individual § 1983 liability in the foster care context. We gain guidance, however, from standards adopted by the Supreme Court and Ninth Circuit in analogous situations.
See, e.g., Daniels,
¶ 13 Two relatively early Supreme Court decisions established general parameters for imposing § 1983 liability upon executive branch officials.
Youngberg,
An inmate must rely on prison authorities to treat his medical needs; if the authorities fail to do so, those needs will not be met. In the worst cases, such a failure may actually produce physical “torture or a lingering death”.... In less serious cases, denial of medical care may result in pain and suffering which no one suggests would serve any penological purpose.
Id.
at 103,
¶ 14 The Supréme Court extended this analysis beyond the prison setting in
Young-berg.
In that case, the Court considered the appropriate standard for determining whether a patient involuntarily committed to a state mental institution could bring suit against institution officials for the alleged breach of the patient’s substantive due process right to reasonable safety and to freedom from unreasonable restraints.
Youngberg,
¶ 15 Based on this reasoning, the
Young-berg
Court held that § 1983 liability may be imposed for executive decisions that are “such a substantial departure from accepted professional judgment, practice, or standards as to demonstrate that the person responsible actually did not base the decision on such a judgment.”
Id.
at 323,
¶ 16 After
Youngberg
and
Estelle,
the Supreme Court decided two companion cases concerning the degree of official misconduct necessary to give rise to liability under § 1983 for a violation of a prison inmate’s due process rights.
See Daniels,
¶ 17 In
Daniels,
a prison inmate brought a § 1983 claim alleging a prison official deprived him of his due process rights by negligently placing a pillow on a prison stairway, causing the inmate to slip and injure his back and ankle.
¶ 18 Relying upon this guidance from the Supreme Court, the Ninth Circuit initially held that certain types of gross negligence can implicate the Due Process Clause.
See, e.g., Neely v. Feinstein, 50 F.Sd
1502, 1507 (9th Cir.1995) (“conscious indifference amounting to gross negligence”);
Houghton v. South,
¶ 19 In O’Connor, the Ninth Circuit considered the implications of Daniels and Davidson for determining whether a state actor may be held hable, under the professional judgment standard, for violating the rights of an involuntarily committed mental patient. The O’Connor court concluded that Daniels and Davidson did not affect the Youngberg test:
Under Youngberg’s balancing test, the risk of harm and the burden on the state are weighed in examining discretionary management choices for reasonableness. Liability may be imposed on a professional state officer only when his or her decision is so objectively unreasonable as to demonstrate that he or she actually did not base the challenged decision upon professional judgment. We believe that this standard is equivalent to that required in ordinary tort cases for a finding of conscious indifference amounting to gross negligence. Certainly, the Youngberg standard is far more stringent than that required for a finding of negligence, which may be demonstrated by a professional’s mere failure to exercise the level of care expected of other professionals in the same field. We therefore hold that the inquiry relevant under Youngberg has not been affected by the Courts intervening decisions in Daniels and Davidson.
O’Connor,
¶ 20 Similarly, the Ninth Circuit held that police officer conduct amounting to gross negligence or recklessness
4
would constitute a violation of the constitutional right to be free from excessive force and would subject an officer to § 1983 liability.
Fargo,
¶ 21 Recent Ninth Circuit case law, however, rejects the
Fargo
standard and raises a serious question about the continued validity of the professional judgment standard as applied in
O’Connor
and similar decisions.
See Grubbs II,
[I]n order to establish Section 1983 liability in an action against a state official for an injury ... the plaintiff must show that the state official participated in creating a dangerous condition, and acted with deliberate indifference to the known or obvious danger in subjecting the plaintiff to it. ... Deliberate indifference to a known, or so obvious as to imply knowledge of, danger, by a supervisor who participated in creating the danger, is enough. Less is not enough.
Id.
at 900 (emphasis added);
see also McGrath v. Scott,
¶ 22 In redefining and applying the deliberate indifference standard, the
Grubbs II
court also examined the continued validity of the
O’Connor
professional judgment standard. The court reasoned that
Neely,
in which the court had held that “conscious indifference amounting to gross negligence” was enough to impose liability under the professional judgment standard,
Neely,
While Neely can be distinguished on its facts from the present case, its language ... is either incorrect to the extent that it approves the gross negligence standard, or it must be limited to the claims of inmate plaintiffs injured because of a miscarriage of the “professional judgment of a government hospital official” in the context of a captive plaintiff.
Grubbs II,
¶23 Two years after the Ninth Circuit’s
Grubbs II
decision, the Supreme Court reviewed another Ninth Circuit decision in an analogous area of § 1983 liability.
Sacramento,
¶ 24 Reversing the Ninth Circuit, the Supreme Court emphasized the relatively narrow scope of constitutionally-based § 1983 actions. The Court noted that the conduct of the officer fell within the middle range of culpability, somewhere between negligence, which is “categorically beneath the threshold of constitutional due process,” and “conduct intended to injure in some way unjustifiable by any government interest.”
Sacramento,
¶25 The Court emphasized again that “only the most egregious official conduct can be said to be ‘arbitrary in the constitutional sense,’ ”
id.
at 846,
¶26 The Court also recognized, however, that due process guarantees cannot be mechanically applied.
Id.
at 850,
¶ 27 Both Grubbs II and Sacramento held that, as to the situations considered, nothing less than deliberate indifference to a known or obvious danger on the part of a public official involves behavior that rises to a constitutionally conscience-shocking level. Neither decision, of course, considered the behavior sufficient to rise to such a level when the state places or monitors a foster child. We consider, then, whether deliberate indifference or some other level of behavior gives rise to liability in the foster care context.
III.
¶28 The
Grubbs II
standard, applied to the foster care context, would require that state workers responsible for placing and supervising a child in foster care could not be held liable under § 1983 unless they exhibited deliberate indifference to a known or obvious danger to the child. Weatherford argues that applying that standard will encourage those responsible for the well-being of foster children to deliberately overlook information that could place them on notice of dangerous conditions. Officials should not be less likely to incur liability, she argues, if they fail to consider available information. We agree that a child’s right to reasonable safety while in foster care demands more from state workers than attention to known or obvious dangers. We hold, therefore, that a foster child can establish § 1983 liability against a state official by showing that the official, without justification, acted with deliberate indifference by placing a child in foster care or by maintaining a placement when the official knew that the placement exposed the child to danger or would have known of the danger but for the official’s deliberate indifference. If a state worker, with time to consider the placement for a foster child, acts with such deliberate indifference as to ignore information indicating that the placement will result in danger to the child or refuses to obtain information that, if considered, would reveal a danger to the child, the official’s indifference is suffi
ciently
¶29 This standard reflects the Supreme Court’s admonition that executive behavior violates § 1983 only if it involves an element of using the state’s power in an oppressive manner.
Daniels,
¶ 30 The standard also incorporates the Ninth Circuit’s admonition that anything less than deliberate indifference is not sufficient to establish § 1983 liability. The standard reflects the principle, however, that the state, once it undertakes to make a person dependent upon its care, also undertakes an affirmative duty to assume responsibility for that person’s safety and general well-being.
DeShaney,
¶31 The standard we articulate today is also similar to the standard of conduct required by other circuit courts of appeals, whether denominated a “deliberate indifference” or “professional judgment” standard, in the foster care context.
See Yvonne L. v. N.M. Dep’t of Human Servs.,
¶ 32 In
Yvonne L.,
for example, the plaintiffs asserted the right “not to be placed in a foster care environment involving a known or reasonably suspected risk of harm by a third party.”
¶33 As
Doe
and
Yvonne L.
demonstrate, when applied to the unique facts of the foster care context, not much difference exists between the “deliberate indifference” and “professional judgment” standards.
Yvonne L.,
¶ 34 Applying this standard to the facts of this case, we reverse the trial court’s grant of summary judgment. On remand, the court must consider whether, under the standard articulated today, undisputed material facts permit the court to conclude, as a matter of law, that defendant social workers acted with deliberate indifference sufficient to impose responsibility either for'the decision to place
IV.
¶ 35 For the reasons described above, we vacate that part of the court of appeals’ opinion set out in paragraphs twenty-two through thirty and approve the remainder of the opinion, reverse the trial court’s grant of summary judgment to these defendants with regard to the § 1983 claim, and remand for further proceedings consistent with this opinion.
Notes
. The court of appeals decided a number of other issues affecting defendants’ liability. We granted review only of the question pertaining to § 1983 liability.
. In
DeShaney v. Winnebago County Department of Social Services,
Had the State by the affirmative exercise of its power removed Joshua from free society and placed him in a foster home operated by its agents, we might have a situation sufficiently analogous to incarceration or institutionalization to give rise to an affirmative duty to protect. Indeed, several Courts of Appeals have held, by analogy to Estelle and Youngberg, that the State may be held liable under the Due Process Clause for failing to protect children in foster homes from mistreatment at the hands of their foster parents.

. While acknowledging that "it is a
constitution
we are expounding,"
M’Culloch v. Maryland,
. Defining terms such as negligence, gross negligence, and recklessness is, at best, inexact. As between negligence and gross negligence, negligence suggests "a failure to measure up to the conduct of a reasonable person."
