I mean, have you received a summons (letter) from the courts telling you that you’re selected to be a juror. You show up to the courts and assigned a number along with being asked about occupation, status or whether you know anything related to the case in question & etc. but is the probability on becoming part of the 12 jurors that high? Is it also a criminal offense for failing to show up?
You’ll be in a pool of ~200 that gets whittled down to around 30. If you aren’t selected and the reason isn’t universally disqualifying you will go back into the pool for the next trial and so on for 2 years iirc.
Your jury notice(s) will make it explicit the consequences for dereliction of civic duty.
