In a death row appeal soon to come before the US Supreme Court, Robert McCoy will ask whether it is unconstitutional for defence counsel to tell a jury that his client is guilty, in defiance of the accused’s express instructions that he is innocent. McCoy’s lawyer did this in his 2011 murder trial in Louisiana, in a misguided attempt to get his client life imprisonment instead of the death penalty. The lawyer had rejected the opinions of psychiatrists who had found McCoy fit for trial, believing that he was insane and delusional, and that the only way to save his life was to tell the jury he had committed the three murders with which he was charged, in the hope of leniency. The jury promptly convicted McCoy of first-degree murder, and he was sentenced to death.
