Sykes v. United States, 564 U.S. 1 (2011), was a case in which the Supreme Court of the United States held that felony vehicle flight, as proscribed by Indiana law, is a violent felony for purposes of the residual clause of the Armed Career Criminal Act (ACCA).

[1] Writing for the majority, Justice Kennedy wrote that vehicle flight requires officers to give chase, resulting in more injuries on average than burglary.

[2] Dissenting, Justice Scalia criticized the majority for producing an ad hoc judgment based on vague legislation, suggesting they should declare the residual clause of the law unconstitutionally vague.

[3] The court would follow that advice several years later in Johnson v. United States and declare the residual clause unconstitutionally vague.
