Got called to jury duty a couple times while living in California.
At some point, depending on how the question is asked or how the subject is broached, I have to inform the court that I reserve the right to exercise Jury Nullification. As a result, I got dismissed by the prosecutors in both cases.
A Kangaroo court is an attempt to deceive. Deception is key to the definition, because if there was no attempt to deceive the penalty on the accused would be applied without delay or deliberation. No sham court would take place.
So your categorization does not apply to the concept of jury nullification because there is no attempt to deceive. Jury nullification simply adds judgement of the law itself to the mix of the factors being deliberated in a case.
Even the government has difficulty being consistent in its application of the law because it rejudges the law constantly and tweeks it and redefines it to suit the case du jour it wishes to prosecute.
