@mjg59 I had jury duty a few months ago, where I was not immediately dismissed at the counter. I waited an hour in the waiting room and was informed that everyone in the room was to be screened for one of two trials; mine was for trial B, which was expected to take a week. Watched the orientation video and waited for another few hours while the A jurors shuffled out into a courtroom for screening.
Then the judge comes in and says something like "Sorry, you're all dismissed due to the parties settling. Sometimes all it takes is for them to see that there are jurors ready to start the trial and this is a real thing, for them to admit they should settle." I later learned "sometimes" is greatly understated.
@mjg59 There’s a similar idea in US federal procedure, which has occasionally bitten IP trolls who refuse a settlement offer.
