Sacramento v. Lewis, 523 U.S. 833 (1998), was a decision of the Supreme Court of the United States involving police action in a high-speed car chase.

This case concerned a high-speed chase between Sacramento County sheriff's deputies and two men on a motorcycle: Brian Willard driving and Phillip Lewis as a passenger.

The chase wove in and out of moving traffic and reached speeds up to 100 miles an hour, ending when Willard lost control and the bike tipped over.

The question before the Court was: Does a police officer violate substantive due process by causing death through reckless indifference to life in a high-speed chase aimed at apprehending a suspected offender?

Thus the Court held: "High-speed chases with no intent to harm suspects physically or to worsen their legal plight do not give rise to liability under the Fourteenth Amendment" In Kennedy's concurrence, he warned that the "shock the conscience" test should be treated with skepticism due to its subjective nature.
