Facts

After officers attempted to arrest Israel Leija, Jr., he fled onto Interstate 27 and led police on an 18-minute, 25-mile chase at 85 to 110 miles per hour. During the chase, Leija twice called the dispatcher, said he had a gun, and threatened to shoot police officers if they did not stop pursuing him; officers also received a report that he might be intoxicated. Officers deployed spike strips at three locations, including beneath the Cemetery Road overpass, where Trooper Mullenix took a position above the highway and decided to shoot at Leija's car to disable it. As Leija approached the overpass with another officer in pursuit and an officer positioned below, Mullenix fired six shots; Leija's car then hit the spike strip, crashed, and Leija died from Mullenix's gunfire.

Issue

Whether Trooper Mullenix was entitled to qualified immunity on respondents' Fourth Amendment excessive-force claim. More specifically, whether existing precedent clearly established that Mullenix's conduct in these particular circumstances violated the Fourth Amendment.

Rule

An officer is entitled to qualified immunity unless existing precedent placed the constitutional question beyond debate such that every reasonable official would understand the particular conduct to be unlawful. Courts may not define clearly established law at a high level of generality; the inquiry must be undertaken in light of the specific context of the case, with special attention to the facts confronting the officer in Fourth Amendment excessive-force cases.

One of 10 multiple-choice questions for this case. Pick an answer to see why.

In rural New Mexico, Deputy Aaron Pike joined a 20-mile nighttime pursuit of Nolan Cruz, who was driving between 90 and 105 miles per hour on Interstate 25. Dispatch relayed that Cruz had called twice during the chase, claimed to have a handgun, and threatened to shoot any deputy who tried to stop him. As Cruz sped toward a roadblock staffed by officers, Pike fired at the SUV from an overpass; Cruz died, and his estate sued under §1983.

Assume no prior precedent squarely addresses an officer shooting at a fleeing driver under these circumstances, but the plaintiff cites general excessive-force cases stating that deadly force requires a serious threat. Is Pike most likely entitled to qualified immunity?

Explanation. Qualified immunity turns on whether existing precedent made the unlawfulness of the officer’s particular conduct clear beyond debate. The majority stressed that courts may not define clearly established law at a high level of generality, especially in Fourth Amendment excessive-force cases. General statements that deadly force requires a sufficient threat do not, by themselves, clearly establish that shooting at a fleeing, armed, threatening, high-speed driver approaching officers is unlawful.
