Hi,
It's not usual for a legal advisor to read out a judgement, but provided it is obvious that the magistrates have formulated it, they don't have to read it. ( For example, if the magistrate has lost their voice.)In some cases, reasons are sent by post, to save the parties from staying. It is usual that the judgement is given verbally first, though.
For your second question, you can appeal any decision you feel has been reached without merit. If you feel that a magistrate has not considered the evidence because they were asleep, you could make an appeal. You can, as Boom says also write to the advisory committee.
