Ah, but Messi_10, the picture shows the judge in his formal QC's attire. We've been spared a sight of the knee breeches, stockings, and gilt-buckled shoes that go with it. In court he wears a short wig and what looks like a dressing gown. Not at all prattish ! (?)
Bit surprising how lenient the judge was. I suppose that he was thinking of a fine, which was pointless, and that she hadn't caused the trial to be abandoned.
In the old days, before the challenging of jurors was abolished, jurors were commonly challenged by counsel because the juror looked unlikely to understand, particularly if the juror couldn't read the oath before a case with many documents. No reason had to be given; defence counsel just said "Challenge!"
