Washington, D.C. – Taylor is contesting the state's use of a three-stage chemical injection to execute inmates.
The argument has been rejected in lower courts, but the full Eighth U-S Circuit Court of Appeals agreed Wednesday to hear the appeal.
It's not certain when that might happen.
Taylor pleaded guilty in the 1989 abduction, rape and murder of a teen-age Kansas City girl who was grabbed while waiting for a school bus.
