A U.S. Supreme Court case on police authority under the Fourth Amendment to stop and detain a gun suspect has been resolved by the U.S. Court of Appeals, but not to the benefit of defendant Chunon Bailey.

Bailey had appealed to the Supreme Court after the Second Circuit upheld his convictions for gun possession and drug dealing. He won a measure of victory in 2013 when the Supreme Court said police exceeded their power to detain him for a search when they stopped him a mile from the apartment where other officers, armed with a search warrant, were looking for a gun.
