In a mistrial it is as if the trial had never happened. The case can be retried before another jury. There may be a problem here since the verdict was announced. The question is that since jeopardy had attached and the verdict of acquittal was announced, would a retrial constitute double jeopardy?

Whether the judge has to accept or approve the verdict may be a question also.

There can be no double jeopardy if the first trial never happened.
