The only one who appeals is the one who loses the court case.
The point of the thread was impeaching judges, and people being against that just for ruling against Trump. If these judges are getting appealed on decisions, and the appellate courts continuously overturn the same judges who only judge against Trump, then that would deserve a review and possibly an impeachment. Even if it had been happening against Biden, I would say the same thing.
And yes, if the SCOTUS rules against Trump, that's part of the whole checks and balances, so the admin should abide by the decision and shut up.
