Re: Jury Trial
IANAL but the offence he was charged with is an "either way" offence.
He (and the magistrate) could have elected to have the case tried in Crown Court (i.e. with a Jury), though the Crown Court is able to give stiffer punishment. It's quite possible he was advised against going to Crown Court in order to avoid stiffer penalties.
In case anyone is under the mis-apprehension you ALWAYS get a choice, you don't. In fact even with an "either way" offence, they don't necessarily have to give you the choice.
