Some red faces on the other side
Plaintiffs sue Harrisburg, PA, in state court, over its gun restrictions (I assume on preemption grounds). Harrisburg files a removal to Federal District Court (I assume some Federal legal issue was involved, don't know the details). But the removal motion omits one plaintiff, so plaintiffs' attorney Joshua Prince files for default judgment in state court, in the plaintiff's name, since the city never answered the complaint. He reportedly gives notice to Harrisburg (some rules require giving advance notice of an intent to take a default judgment) and the city ignores it. So he takes a default judgment for $20,000 plus.
Now the city wakes up and moves to set aside the default judgment. That's possible, but if the PA rules are like the federal ones, it's a heavy burden of proof. And the first question is going to be "he gave you written notice, well in advance, that he would take a default ... why didn't you object then, or move to add this plaintiff to your removal motion?"
