Log: Jury duty?

Apparently I must attend something called Jury Duty. From what I understand, this is a court trial, however I don't believe I've ever heard of a Jury. From what my father told me, court trials consist of proving whether or not someone committed a crime. A judge, usually the king or a trusted ally, presides over the trial. The convicted pleads his case, the evidence presented, then the final judgement takes place. I never wanted to, but I knew, when I became king, I'd have to do this. Fortunately, Altea was always peaceful and we rarely had trials. But what is a jury? I've never heard of anything like that.

And now I'm placed on a Head Seat? I'm so royally confused. So I must preside over something which I know nothing about? Forcefully? I do despise this termination business.
