That's not great news.
She was so egregiously biased in favor of trump that the Appellant court overturned virtually every thing she found, ripping her up and down in the process. You'll never read an Appellant court ruling that is a more brutal take down of a garbage judge......than you will the 11th court's take down of her rulings in the Mar-a-lago case.
It is a point by point evisceration of essentially every point that Cannon offered as legal justification for her rulings in Trump's favor. They slaughter Cannon, accusing her of rewriting the rules, radical reordering of caselaw, and inserting herself in the investigation of the case in a way that would violate bedrock separation-of-powers limitations.
And they don't stop with just obliterating Cannon's legal reason. They dismiss the ENTIRE proceeding, throwing Cannon off the case.
Here is hoping she's learned something since then.
