The Massachusetts Supreme Judicial Court has upheld the dismissal of a criminal charge against a New Hampshire resident who was carrying a firearm in Massachusetts without a license. This decision reinforces the state's authority to enforce its stringent gun laws on out-of-state residents who possess firearms legally in their home states. The court's ruling indicates that Massachusetts' current gun licensing laws apply to New Hampshire residents bringing their legally obtained weapons across state lines. The implications of this ruling, particularly in light of previous cases such as Commonwealth v. Marquis, remain to be fully understood as legal experts analyze its potential effects on similar future cases.
