Margaret Trudeau, the ex-wife of former Canadian Prime Minister Pierre Trudeau, had her drunken driving charge thrown out of court by a judge on Tuesday.
Trudeau, whose 1970s escapades with the Rolling Stones and at New York's Studio 54 helped earn her notoriety in Canada and abroad, registered a blood-alcohol level of 107 milligrams of alcohol per 100 milliliters of blood.
The legal limit is 80 milligrams.
But Ontario Court Judge Lise Maisonneuve said police officer Trevor Archibald's testimony was unreliable and that he stopped her arbitrarily on an Ottawa street the night of May 30, 2004.
According to the judge Archibald also denied Trudeau access to her counsel of choice when he neither left a message nor gave her the option to leave a message when he called the first two lawyers she requested at the Ottawa police station.
