The appeal will be based on any or all of the many factors in the trial that should have caused it to be declared a mistrial. * Prosecutorial misconduct, particularly in the rebuttal to the closing statements. * Tainting of the jury by media and politician comments before the jury was sequestered * The refusal of the judge to poll the jury as to whether they were effected by the comments made (as is required under that state's legal proceedures) * The dumping of thousands of discovery documents, compiled deliberately in a manner that made them unsearchable and unable to be used until they were printed out and re-sorted. They were dumping something like 500 separate documents on the defence per day.. during the trial. * Others, that I just can't remember off the top of my head right now. There are quite a few legal reasons why the verdict could be appealed. I think the judge did this deliberately as he knew the Chauvin was not guilty, but also knew that if he was the judge that found him not guilty, he would be a dead man. The jury understood this too. This is trial by angry mob and a death blow to the already mortally wounded justice system in the US.
