Judge Julie McDonald, 49, of Bloomfield Hills, was caught on video in September apparently during a traffic stop, police said.
According to the video, McDonald failed a road sobriety test after being stopped on suspicion of speeding.
Police said McDonald smelled of alcohol after they stopped her on Woodward Avenue at 10:45 a.m. A blood-alcohol test registered .102, according to authorities.
On Thursday, the Michigan Supreme Court ordered McDonald to take an unpaid 45-day suspension from the bench, according to records.
