I think he'll be found guilty but with a lot of mitigation found.
I bet we don't get the terse "I find the case proved" or "...not proved" which is usual. We'll get some reasoned verdict, like a High Court or County Court one. That will be to reduce options for appeal if it's a conviction; the magistrate won't want a case for appeal to the High Court on a point of law, which both sides can pursue; and will want to explain the decision on the facts for the media. If convicted, Terry's appeal is to the Crown Court. That would be a complete rehearing before a Crown Court Judge and two magistrates. What fun; the whole thing all over again, unless the CPS abandon the case on appeal.
