Superior Court Judge Larry Paul Fidler advised Spector he had a right to testify in his own defense, but Spector chose not to take the stand. The music producer also refused to take the stand in his first trial, which ended with a deadlocked jury that was leaning toward a conviction by a 10-2 vote.
Spector, a legendary music producer, is charged in the 2003 shooting death of Clarkson in his Alhambra mansion.
His defense maintains she was suicidal and killed herself, and claims that Spector's chauffeur may have been mistaken when he said he saw the music producer emerge from the house and heard him say, "I think I killed somebody."
They have cited the noise of the fountain as well as the air conditioning in the car where the chauffeur had been sitting as sounds that might have obscured his ability to hear what Spector said.
The retrial recessed until Monday.
The judge told jurors that testimony in the trial would conclude sometime next week, followed by closing arguments.
