Massachusetts Gov. Maura Healey has signed an emergency preamble to the state’s sweeping gun control bill, fast-tracking its implementation and halting an ongoing effort by gun rights activists to delay its effects.
The law, H.4885, was originally scheduled to take effect on Oct. 23, or 90 days after Healey signed the bill in July, but her decision to proceed with signing the emergency preamble means it goes into effect immediately.
Under Massachusetts law, governors have the authority to issue an emergency preamble to expedite legislation when “the immediate preservation of the public peace, health, safety, or convenience” is deemed necessary.
The law’s expedited enactment was praised by gun control groups but sharply criticized by gun rights advocates, who had hoped to gather enough signatures to delay its implementation until a potential 2026 referendum.
H.4885 expands Massachusetts’ already strict gun regulations, in part as a response to the 2022 Supreme Court ruling in New York State Rifle & Pistol Association v. Bruen, which affirmed an individual’s right to carry firearms in public for self-defense.
The expedited law includes provisions banning untraceable “ghost guns,” expanding restrictions on “assault-style” firearms and large-capacity magazines, and tightening the state’s “red flag” rules. It also mandates that firearm license applicants pass a standardized safety exam and complete live-fire training, while also providing mental health information to local licensing authorities.
