AFAIK, the judge deciding a verdict can only work this way:
If the jury finds the accused guilty, the Judge can override that and declare them not guilty.
But if a jury finds them not guilty, set, match, game over. That’s the whole point of the jury, so that it’s not some big wig high paid snob deciding cases.
Well, that is even more of an excuse that this jury should have ignored the judge and voted their conscience.
