Defense lawyers said they will appeal because Arapahoe County District Judge Carlos Samour's schedule does not give them enough time to prepare, the Denver Post reported. Tamara Brady, a member of the defense team, said another appeal -- of Samour's order for a second psychiatric evaluation -- could go to the U.S. Supreme Court.
"That would certainly delay things," she said.
Holmes was arrested after the July 2012 mass shooting during a midnight showing of "The Dark Knight Rises" that left many people in the audience wounded and 12 dead.
Because of the massive publicity surrounding the case, Samour said 6,000 prospective jurors will be summoned initially. Jury selection could take several months.
