Sorry, but if a law goes against the clear meaning of the Constituion, either federal or state, I am in no way obligated to adhere to it if I am on a jury. Otherwise, why have juries? Let judges do the determination of guilty or now.
Simply remove the “nullifier” from the prospective pool or challenge them for cause. Jury nullification nuts like marijuana addicts cannot be reasoned with. Just what we need in our country is some individual nut who believes he can privately determine what is or is not constitutional. The social agreement, in general terms, dictates we surrender our private judgement in return for legislation by an authorized body. I would not have a nullifier on any jury hearing my case. Jurors decide facts the legislature and judges give the law.
