From Prude v. Clarke (7th Cir. Mar. 27, 2012):
We order the defendants to show cause within 14 days of the date of this order why they should not be sanctioned for contumacious conduct in this court. If they ignore this order to show cause like the last one, they will find themselves in deep trouble.
The contumacious conduct was that, “In addition to stonewalling the plaintiff and the district judge, the defendants” — county jail officials — failed to file a brief in this court and failed to respond to our order to show cause why they hadn’t filed a brief.” Thanks to How Appealing for the pointer.
