Trio seek federal injunction to block state stun gun ban

Three Massachusetts residents are asking a federal judge to prevent the state from enforcing its stun gun and Taser ban, arguing that their constitutional rights continue to be violated every day the statute remains on the books.

“The Second Amendment to the United States Constitution protects the right to keep and bear arms including non-lethal arms such as Tasers and stun guns, and Massachusetts’ complete ban on the possession and sale of electrical weapons violates this right,” wrote attorneys for the three Bay Staters — Christopher Martel, Donna Major and Madeleine Bates.

The motion for a preliminary injunction asks U.S. District Court Judge Douglas P. Woodlock to prevent authorities from enforcing its stun gun and Taser ban throughout their ongoing lawsuit against the state. The lawsuit, filed in February in federal court in Boston, argues that the stun gun and Taser law is unconstitutional and should be wiped from the books.

If Woodlock orders that Massachusetts authorities are temporarily banned from enforcing the law, it would be a sign that he sees merit in the case.

The lawsuit was filed on the heels of a U.S. Supreme Court decision last March that showed the law was vulnerable. In that decision, the high court overturned a ruling by the state Supreme Judicial Court that found the Second Amendment does not apply to stun guns.

Although the Supreme Court decision stopped short of invalidating the statute, in a concurring opinion Supreme Court Justice Samuel Alito said the law — as a whole — should be tossed.

“Most all other states permit residents to carry Tasers and stun guns for self-defense,” the motion says. “That fact undermines any effort by Massachusetts to demonstrate exceptional circumstances.”

Attorney General Maura Healey’s office, which is charged with representing the state in the case, will respond to the lawsuit by April 14.
