The U.S. Supreme Court granted a temporary stay of execution for a Georgia inmate whose attorneys argue that the 59-year-old black man’s death sentence was tainted by a juror’s racial bias.

Keith Leroy Tharpe, known as “Bo,” was set to be put to death at 7 p.m. EDT Tuesday at the state prison by injection of the barbiturate pentobarbital. But the hour came and went as the justices considered his case. Just before 11 p.m. EDT, the court announced the temporary stay.
