The U.S. Supreme Court has refused to hear an appeal by Wellington polo millionaire John Goodman, who is serving a 16-year sentence for drunken-driving manslaughter in the drowning of a motorist whose Hyundai was shoved into a canal by Goodman’s Bentley.

The high court Monday rejected a petition seeking review of his conviction and sentence. All told, three appellate courts have either rejected his appeals or refused to hear them.
