Under what circumstances will the court grant me a new trial?
You will be granted a new trial under very rare circumstances where the original trial's verdict was not supported by law. Sometimes a new trial will be granted in rare circumstances when new evidence comes up, but that's up to an appeals court to grant. You will also be issued a new trial if evidence came up that there was serious prosecutorial misconduct in the original trial, termed to be "harmless" or "not harmless" error. And in most cases, if something is omitted in the original trial, or sometimes a question is asked, they term it harmless error; it has to be a very high standard for it to be an error that is not harmless and warrant a new trial.
