> It's kind of like Jury Nullification, where Juries do not strictly need to vote on the merits of whether a person is guilty or innocent, but can vote against the law and know the law can't punish jurors for a "wrong judgement". Judges hate that loophole but know it's a necessary part of democracy.

Juries are not a thing in most countries that are generally considered democracies, so jury nullification can't be all that neccesary.
