WASHINGTON — Police do not have unlimited authority to enter a home without a warrant when pursuing a person suspected of a minor crime, the U.S. Supreme Court ruled on Wednesday in a case involving a California motorist chased home by an officer for honking his horn while listening to music.
By declining to endorse a broad interpretation of police power, the justices handed a victory to the driver, Arthur Lange, who is challenging his conviction of driving under the influence after the California Highway Patrol officer entered his garage without a warrant and performed a sobriety test.
The court, in a 9-0 decision authored by liberal Justice Elena Kagan, sent the case back to the California Court of Appeals. The justices rejected the lower court’s finding that warrants are not required in any situation in which police are in pursuit, even if the suspected crime is minor.
