The big problem is that the potential prosecution (DOJ) agreed with the defense that no further action should be pursued against the defendant, and that the Jack Smith report should never be released (they went further, asking that it be destroyed, but she hasnt ruled on that
yet).
So with no participating party opposing, there is no one with direct involvement to make an appeal. Instead, what has happened is that the Knight First Amendment Institute, part of the law school at Columbia University (NYC), has made an appeal based on First Amendment grounds. I dont understand the basis for this, but Judge Cannon denied this request, however it gave them something to appeal to the 11th Circuit
which is pending. Certainly the judges there understand how the actions in Cannons court are an attempt to whitewash the whole thing and delete history, and that the current DOJ is serving the defendants interests rather than the peoples interests. It remains to be seen how they will rule.
