Perhaps these requests have something to do with the Seventh Circuit's cancellation of previously scheduled oral arguments in two gay marriage appeals out of Wisconsin and Indiana. Earlier this month, the appeals were combined and fast-tracked for oral arguments on August 13.
Late last week, however, the Seventh Circuit issued this release (H/T to Equality on Trial):
The court, on its own motion, ORDERS that the oral argument in this appeal, scheduled for Wednesday, August 13, 2014, is VACATED. A new oral argument date will be set by separate court order.
Okay, but why? It might have something to do with requests from the states of Indiana and Wisconsin to proceed directly to an en banc hearing of the case, rather than the typical three-judge panel.
