The oral arguments for McVeigh will be separate from the appeals court's normal schedule of oral arguments. For now, each side will have 15 minutes to present its case, according to the clerk's office. However, the parties might request more time. All briefs in the case have been filed.

The court is expected to announce April 20 the makeup of the panel that will hear the oral arguments.

Typically, the 10th Circuit hears oral arguments and reserves decision until some later date.

McVeigh's lawyers on Feb. 23 filed a document claiming the government overstated the strength of its case in attempting to block a new trial for McVeigh.
