Warren Lee Hill is set to be executed Tuesday. In a court filing Friday, Hill's lawyer asks a Butts County Superior Court judge to grant a writ of habeas corpus.
The court denied a similar request in July before Hill's original execution date. The state Supreme Court temporarily stayed the execution then.
As part of the filing Friday, Hill's lawyer submitted statements from the three doctors who originally examined him and testified for the state. All three doctors write that they've changed their opinion and believe Hill is mentally disabled.
Georgia law prohibits the execution of the mentally disabled.
Hill's lawyer is also seeking a new clemency hearing.
