New Jersey has admitted the unconstitutionality of its stun-gun law, based upon the SJC decision in the Caetano case, in which the Supreme Court found the Massachusetts ban unlawful:

“[T]he State agrees with defendant that New Jersey's stun-gun statute, N.J.S.A. 2C:39-3h, is unconstitutional in light of Caetano v. Massachusetts, 136 S.Ct. 1027 (2016), and defendant's conviction under that statute should be vacated in the interests of justice.”

I was proud to have done both amicus briefs (MA Supreme Judicial Court and the Supreme Court) for Commonwealth Second Amendment in that case. I am equally proud to see the validity of our argument accepted elsewhere.
