Background
In Kyle LINDSEY and Zayne Mann, Plaintiffs - Appellants, v. Brandon HYLER, Individually and in His Official Capacity as a Webbers Falls Police Officer; The City of Webbers Falls, Oklahoma; Larry Ruiz, in His Capacity as Chief of Police for the City of Webbers Falls; And Bob Ross, in His Capacity as Mayor of the City of Webbers Falls, Defendants - Appellees, the Tenth Circuit reviewed a civil-rights lawsuit arising from a short police pursuit in Webbers Falls, Oklahoma.
Kyle Lindsey was driving a utility vehicle with Zayne Mann as a passenger. Officer Brandon Hyler attempted to stop the vehicle for what the plaintiffs characterized as a minor traffic infraction. Instead of ending with a routine stop, the encounter turned into a brief pursuit. Lindsey later lost control of the utility vehicle on a gravel road, and both Lindsey and Mann were seriously injured.
Lindsey and Mann sued Officer Hyler, the City of Webbers Falls, the police chief, and the mayor. Their basic claim was that the officer should not have started or continued a pursuit over such a minor matter and that his conduct caused the crash. They sought damages under federal civil-rights law, including constitutional theories tied to the Fourth and Fourteenth Amendments. The district court ruled against them, and they appealed to the Tenth Circuit.
The available source material does not provide every operational detail of the pursuit, such as the exact speed, distance, duration, lighting conditions, or the precise traffic violation Officer Hyler suspected. Those details would need source verification before being used in training or policy review.
Issue Before the Court
The plain-English question was whether a police officer violates the Constitution when he initiates a brief pursuit for a minor traffic matter and the fleeing driver later crashes and seriously injures himself and a passenger.
For police officers, the issue was not simply whether the pursuit was wise, whether it complied with best practices, or whether a supervisor might have preferred a different decision. The constitutional question was narrower: did Officer Hyler’s conduct amount to an unconstitutional seizure under the Fourth Amendment, or did it “shock the conscience” under the Fourteenth Amendment’s substantive due process standard?
The court also had to consider whether the city, police chief, or mayor could be liable if the officer’s conduct did not itself violate the plaintiffs’ federal constitutional rights.
Decision
The Tenth Circuit affirmed the ruling for Officer Hyler and the municipal defendants. The court held that the plaintiffs could not establish a federal constitutional violation based on the pursuit and crash.
On the Fourth Amendment theory, a police pursuit by itself is not automatically a seizure. A seizure generally requires physical force or submission to an officer’s show of authority. When a driver does not submit and instead continues driving, the pursuit alone does not become a Fourth Amendment seizure merely because the driver later crashes. Based on the court’s analysis, the crash was not treated as an intentional seizure by the officer.
On the Fourteenth Amendment theory, the court applied the demanding substantive due process standard used in police pursuit cases. In a rapidly developing pursuit, liability does not arise merely because an officer may have been negligent, made a bad tactical decision, acted recklessly, or pursued for a relatively minor violation. Under the governing rule, conduct in this setting must “shock the conscience,” and in high-pressure pursuit situations that generally requires proof that the officer intended to cause harm for reasons unrelated to a legitimate law-enforcement objective.
The Tenth Circuit concluded that the record did not show that Officer Hyler intended to harm Lindsey or Mann for an improper purpose. The pursuit was connected to a legitimate law-enforcement objective: attempting to stop a vehicle for a suspected traffic violation. Because the plaintiffs could not show the required unconstitutional intent or conscience-shocking conduct, their federal claims failed.
The practical rule from Lindsey v. Hyler, 918 F.3d 1109 (10th Cir. 2019), is that a pursuit-related crash caused by a fleeing driver’s loss of control does not automatically create federal constitutional liability for the pursuing officer. In the Tenth Circuit, when an officer makes quick decisions during a pursuit, a plaintiff generally must prove much more than poor judgment or an unnecessary chase. The plaintiff must show conduct that shocks the conscience, typically meaning an intent to harm unrelated to legitimate police work.
Because the court found no underlying constitutional violation by Officer Hyler, the claims against the City of Webbers Falls, the police chief, and the mayor also failed.
Plain-English Implications for Police Work
Lindsey v. Hyler is important for officers because it separates constitutional liability from policy, training, and tactical judgment. The court did not say every pursuit for a minor infraction is good policing. It said that, under the federal Constitution, a brief pursuit that ends when the fleeing driver loses control is not enough by itself to prove a Fourth or Fourteenth Amendment violation.
For patrol officers, the case reinforces that courts give some constitutional breathing room for fast-moving pursuit decisions. If an officer is trying to make a lawful traffic stop and there is no evidence that the officer intended to harm the occupants for an improper reason, a later crash by the fleeing driver is unlikely to satisfy the Tenth Circuit’s substantive due process standard.
At the same time, officers should not read the case as permission to pursue whenever they want. A pursuit can still violate department policy, state law, training standards, or sound risk management even when it does not violate the federal Constitution. The constitutional rule is a floor, not a best-practices manual. Supervisors and agencies may impose stricter limits than the Constitution requires, especially for minor violations, gravel roads, utility vehicles, passengers, weather, traffic, or other risk factors.
For supervisors, the case is a reminder to distinguish after-action review questions from constitutional questions. The after-action review may ask whether the pursuit was necessary, whether the officer considered the seriousness of the offense, whether the risk to the public outweighed the need to stop the vehicle, and whether termination should have occurred sooner. The constitutional lawsuit asks a narrower question: did the officer’s conduct amount to an unlawful seizure or conscience-shocking abuse of government power?
For students and citizens, the takeaway is that serious injury does not automatically mean a constitutional violation occurred. In pursuit cases, federal courts focus heavily on whether the officer intentionally used force to stop the person or acted with an improper intent to cause harm. Lindsey and Mann suffered serious injuries, but the Tenth Circuit concluded that the facts did not meet the high threshold for federal civil-rights liability.
