So to the best I can decipher it, and bearing in mind that trump's lawyers have filed cockamamie nonsense, they filed a notice for an emergency appeal of the PA District Court decision, which they want to be heard right away, and set a short briefing schedule, because of the certification deadline. To do this you file a Notice of Appeal and specify what specifically you're appealing. They earlier said they only wanted to appeal the denial of the opportunity to file a Second Amended Complaint, seeking to change what they were alleging before the trial court, and did not want to appeal the rest of it, including the dismissal of the existing complaint. They basically wanted a do over on the entire litigation before Judge Brann.
Today, they said, no, actually we also want to appeal the dismissal of the First Amended Complaint. We think that was also a viable complaint and should not be dismissed. And because of the timing issues, we only want until 4 pm today to file our papers, and to give the Commonwealth 24 hours to respond.
The Commonwealth is saying WTF. What is being appealed? We have 24 hours to write these papers, and we don't even know what trump is appealing or arguing.
Also, typically, when you file a Notice of Appeal, you have to state everything you are appealing. You can't file a Notice of Appeal, and amend it later on to add new things you thought the trial court got wrong. But trump's lawyers are trying to do just that, and the other side, is saying WTF, but worded more legalese sounding.
