BOSTON - Massachusetts Attorney General Maura Healey announced Friday that she had joined 13 other attorneys general in filing a brief with the U.S. Court of Appeals that seeks to reverse a recent ruling in a case involving Remington Arms and defective firearms.

The amicus curiae, or friend of the court, brief was filed Friday in the 8th Circuit Court of Appeals. It seeks to overturn a ruling from March involving a class action suit filed against Remington Arms that claimed the company sold as many as 7.5 million firearms with defective triggers.

The original suit charged that because of defects, the guns were prone to fire accidentally without the triggering being depressed, and that Remington officials knew this for decades and did nothing about it.

In March, U.S. District Judge Ortrie D. Smith in Kansas City approved a settlement in the case that does not include any financial penalties for Remington but allows owners of guns with faulty triggers to have them replaced by Remington at no cost.

As a result of the ruling, Remington recently launched a recall effort. Owners of certain models may file a repair claim through the company's website.

Models covered in the recall include:

Remington Model 700, Seven, Sportsman 78, 673, 710, 715, 770, 600, 660, XP-100, 721, 722, and 725 firearms containing a Remington trigger mechanism that utilizes a trigger connector.

Also included are Remington Model 700 and Model Seven rifles containing an X-Mark Pro Trigger manufactured between May 1 2006 and April 9 2014 that would not repaired in a previous recall, and

Current and former owners of Remington Model 700 and Model Seven rifles who replaced their rifle's original Walker trigger mechanism with an X-Mark Pro trigger mechanism.

The brief filed by the attorneys general criticizes the settlement for ending legal claims for firearm owners while leaving consumers and the public at risk of death or injury from faulty firearms.

Healey's statement said that of the 7.5 million guns covered under the case, only a small fraction, an estimated 25,000, are expected to be repaired.

A statement issued by her offices reads "Documents show that Remington has been aware of the defect for decades and has declined to fix it, for reasons that include potential exposure to personal injury liability and the cost of alternative trigger designs. In the intervening time period, there have been hundreds of reports of personal injuries, including deaths, as well as of significant property damage."

Joining Massachusetts in calling for an appeal are the attorneys general from the states of California, Hawaii, Illinois, Maine, Maryland, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Vermont, and Washington, and from the District of Columbia.
