A US death row inmate faces a Tuesday afternoon deadline to inform prison officials whether he wants to be executed by lethal injection or electrocution.
David Earl Miller, in prison in the US state of Tennessee, is scheduled to die on December 6 for the 1981 murder of 23-year-old Lee Standifer in Knoxville.
Lethal injection is Tennessee's preferred execution method, but inmates whose crimes were committed before 1999 have the option of choosing the electric chair.
A federal judge last week ruled against Miller in a case that challenged both methods of execution.
On Monday, Miller's lawyers asked the court to reconsider.
In a separate case, the US Supreme Court on Monday declined to consider arguments that Miller had bad lawyers at sentencing who did not retain experts to discuss his abusive childhood.
