I mean, have you recieved a summons (letter) either from your municpality or another in which you’re selected to be a juror. You show up to the courts and assigned a number along with being asked about occupation, status, etc. but is the probability even that high on becoming part of the 12 jurors? Is it a criminal offense for failing to appear?
Jury Nullification has nothing to do with a citizen’s obligation to serve on a Jury. That is related to how a Jury finds someone innocent.
I know what it is, I am saying that judges don’t like people knowing about it and in practice will block you from being on the jury if you make it clear that you do. In that sense it does have to do with the enforceability of an obligation to serve on a jury.
