In Castle Rock v. Gonzales, 545 U.S. 748 (2005), the U.S. Supreme Court ruled 7–2 that a person holding a restraining order has no constitutional right to have the police enforce it. Jessica Gonzales could not sue the Castle Rock, Colorado police department under the Fourteenth Amendment after officers failed to arrest her estranged husband for violating a protective order, even though he went on to murder their three daughters. The Court held that a Colorado statute directing officers to arrest violators of protective orders did not create a personal entitlement protected by the Due Process Clause.
What Happened
In May 1999, during divorce proceedings, Jessica Gonzales obtained a restraining order requiring her estranged husband, Simon Gonzales, to stay at least 100 yards from the family home and away from her and their three daughters, Rebecca (10), Katheryn (9), and Leslie (7). Limited pre-arranged visits were permitted.
At about 5:30 p.m. on June 22, 1999, Simon took the three girls from outside the family home without any prior arrangement. Jessica called the Castle Rock Police Department and reported the violation. Officers came to the house and told her to wait to see if the children came back.
Over the next several hours, Jessica called the police repeatedly. She reached Simon on his cell phone, learned he had taken the children to a Denver amusement park, and passed that information to the department. Officers told her to wait until 10:00 p.m., then until midnight. She went to the station in person around 12:40 a.m. and was told to wait for an officer who never came. She called again around 1:00 a.m., and an officer took a report but did nothing further.
At approximately 3:20 a.m., Simon drove to the Castle Rock police station and opened fire with a semiautomatic handgun he had purchased earlier that evening. Officers returned fire and killed him. The bodies of all three daughters, whom he had already murdered, were found inside his pickup truck.
The Colorado Mandatory Arrest Law
The case turned on a Colorado statute directing that a peace officer “shall use every reasonable means to enforce a protection order” and “shall arrest” a person who violates one, provided the officer had probable cause and the violator had been properly served. In legal drafting, “shall” typically signals a mandatory duty.
The restraining order itself carried a notice to law enforcement on the back, stating that officers “shall arrest, or, if an arrest would be impractical under the circumstances, seek a warrant” when they had probable cause of a violation. Jessica Gonzales argued that this language stripped officers of any discretion once they had probable cause to believe Simon had violated the order.
How the Case Reached the Supreme Court
Gonzales sued the Town of Castle Rock and individual officers under 42 U.S.C. § 1983, the federal statute allowing suits against local governments for civil rights violations. She argued the department violated the Fourteenth Amendment’s Due Process Clause by ignoring her calls.
The federal district court dismissed the case. The full Tenth Circuit, sitting en banc, reversed on the town’s liability, finding a viable procedural due process claim, though it held the individual officers protected by qualified immunity. The Supreme Court granted review and reversed the Tenth Circuit.
What the Supreme Court Decided
Justice Antonin Scalia wrote the majority opinion, joined by Chief Justice Rehnquist and Justices O’Connor, Kennedy, Souter, Thomas, and Breyer. The decision turned on two connected questions: whether the Colorado statute created a personal entitlement to police enforcement, and whether any such entitlement counted as “property” under the Fourteenth Amendment.
Police Discretion Survived the Word “Shall”
The majority acknowledged the statute’s mandatory language but concluded that “shall arrest” did not actually eliminate police discretion. Scalia pointed to a long tradition of officers exercising judgment even under statutes that appear to command specific action. An officer still had to assess probable cause, evaluate the situation, and judge whether an arrest was practical. The statute itself allowed officers to seek a warrant instead of making an arrest when arrest “would be impractical.”
Mandatory arrest statutes, the Court reasoned, are better understood as instructions guiding police priorities than as ironclad guarantees to individual people. That reading preserved what the majority described as a deeply rooted feature of American policing: discretion over how and when to act.
No Protected Property Interest
Even if the statute created some form of entitlement, the Court held it would not qualify as “property” under the Fourteenth Amendment. A protected property interest requires “a legitimate claim of entitlement” to the benefit, not merely an expectation.
Police enforcement of a restraining order, the majority found, does not resemble traditional property. It has no monetary value, cannot be transferred, and does not belong to the holder the way a welfare check, a professional license, or a piece of land does. The Court characterized the benefit of having someone arrested as an indirect byproduct of the criminal justice system, not a personal asset. Expanding property to cover every mandatory-sounding statute, the majority warned, would convert routine government operations into constitutionally enforceable individual rights.
The Dissent
Justice Stevens dissented, joined by Justice Ginsburg. The dissent argued the majority ignored what the Colorado legislature had clearly set out to do. Stevens pointed to legislative history, including statements from the bill’s sponsor, emphasizing that police must enforce domestic restraining orders without exercising discretion. Colorado, in the dissent’s view, had specifically eliminated the traditional presumption of police discretion for domestic violence protective orders.
Stevens read the restraining order as creating a genuine individual benefit with real value to its holder, even if not measurable in dollars. When a state passes a law designed to make police action mandatory and prints enforcement instructions on the back of the order itself, the dissent argued, it has created the kind of legitimate entitlement the Due Process Clause protects. Otherwise, mandatory arrest statutes are hollow promises, and victims who rely on protective orders have no constitutional remedy when the system fails them.
The DeShaney Backdrop
The ruling built on DeShaney v. Winnebago County Department of Social Services (1989), where the Court held that a state’s failure to protect a child from his abusive father did not violate the Due Process Clause. The Clause, the Court said in DeShaney, “is phrased as a limitation on the State’s power to act, not as a guarantee of certain minimal levels of safety and security.” The only exception was where the state itself restricts a person’s ability to protect themselves, such as through imprisonment or involuntary commitment.
DeShaney set the baseline: no general constitutional duty to protect against private violence. Castle Rock answered the narrower question of whether a specific statute commanding police to arrest could create an enforceable right. The Court’s answer was no.
What the Ruling Means for Restraining Order Holders
The practical takeaway is sobering. A protective order gives law enforcement the authority to arrest a violator and can serve as powerful evidence in criminal proceedings, but under Castle Rock it does not create a federally enforceable right to police action. Even a state statute using “shall arrest” language will not, on its own, support a federal civil rights suit when officers fail to respond.
That does not make protective orders worthless. They still authorize arrest, document the danger for future proceedings, and can support state-law remedies where those exist. But holders should not assume that a mandatory arrest statute guarantees a police response, and they should not assume that a failed response creates a federal claim under § 1983.
Since the decision, many states have revisited domestic violence enforcement protocols, adjusting training requirements and accountability mechanisms for officers who fail to respond to reported violations. The ruling also drew attention to gaps in national databases tracking restraining orders and domestic violence convictions, since one longstanding barrier to enforcement is officers not knowing whether a valid order exists.
The Human Rights Commission Follow-Up
After exhausting her options in U.S. courts, Jessica Gonzales, who had changed her legal name to Jessica Lenahan, petitioned the Inter-American Commission on Human Rights. In August 2011, in Case No. 12.626, the Commission found that the United States had violated the American Declaration of the Rights and Duties of Man.
The Commission concluded that the failures to protect Lenahan and her daughters amounted to a form of discrimination, occurring “in a context where there has been a historical problem with the enforcement of protection orders; a problem that has disproportionately affected women since they constitute the majority of the restraining order holders.” It also found that the United States failed to adequately investigate both Jessica’s earlier complaints and the circumstances of her daughters’ deaths.
The Commission recommended that the United States investigate the systemic failures around enforcement of Lenahan’s order, provide full reparations to the family, adopt federal and state legislation making enforcement of protection orders mandatory with effective implementation mechanisms, and train law enforcement on domestic violence response. IACHR rulings are not legally binding on the United States, but the decision remains a reference point in human rights advocacy on domestic violence.
