The New Jersey Attorney General’s Office claimed in a court filing Wednesday that a key document filed in court by the plaintiff in a suit over blueprints for making 3-D guns was falsified.

In the recently filed Defense Distributed v. Grewal, the plaintiffs accused the office of Attorney General Gurbir Grewal of violating their constitutional rights by sending a “takedown notice” to Cloudfare, the California company hosting www.codeisfreespeech.com, a website with information about 3-D printing of firearms.
