Scope: courtwide

In federal courts of appeals, oral argument is allowed unless a three-judge panel unanimously finds one of Rule 34's specified grounds for dispensing with it; the clerk provides the date, time, place, and time allocation.

Evidence excerpt: Oral argument must be allowed in every case unless a panel of three judges who have examined the briefs and record unanimously agrees that oral argument is unnecessary
