The US Supreme Court on Monday upheld California's "catch-all" jury instruction for death penalty cases, ruling that the instructions provide adequate opportunity for jurors to weigh evidence that favors the defendant. In a 5-4 decision in Ayers v. Belamontes, the Court reinstated Belamontes' conviction for first degree murder in the killing of a 19 year old woman during a burglary. Belamontes had appealed his death penalty sentence, arguing that the jury instructions did not require the jury to consider all mitigating factors, including his probable future conduct in prison. The US Court of Appeals for the Ninth Circuit vacated the sentence and California prosecutors appealed to have his sentence reinstated.
