The Connecticut Supreme Court ruled that the families of the Sandy Hook shooting victims could sue a gun maker, a decision that could open the floodgates to more lawsuits.

The Connecticut Supreme Court ruled on March 14 that families of the Sandy Hook Elementary mass shooting victims could proceed with a lawsuit against the companies that manufactured and sold the semiautomatic rifle used in the attack.

The ruling, which reversed a lower courtโ€™s decision, has the potential to unleash a flood of claims by gun violence victims against gun manufacturers โ€“ if itโ€™s upheld by the U.S. Supreme Court, that is.

My research on the history of lawsuits against the gun industry has documented the failure of gun violence victims to hold gun manufacturers liable for legal marketing practices that many people consider irresponsible. The latest Sandy Hook decision could pave the way for gunmakers to finally be held responsible for them.

Interpreting โ€˜applicableโ€™

A 2006 law called the Protection of Lawful Commerce in Arms Actgrants gun manufacturers immunity from lawsuits that arise out of the criminal misuse of a weapon.

The Sandy Hook families argued that their lawsuit fell under an exception to this federal immunity. The exception allows gun violence victims to sue a manufacturer who โ€œknowingly violated a state or federal statute applicable to the sale or marketingโ€ of a firearm.

The families claimed that Remington Arms โ€œmarketed, advertised and promoted the Bushmaster XM15-E2S for civilians to use to carry out offensive, military style combat missions against their perceived enemies.โ€ They said that this marketing constituted an unfair trade practice under Connecticut law, which they argued is a state statute โ€œapplicableโ€ to the marketing of a firearm.

The Connecticut high court agreed and, importantly, interpreted the term โ€œapplicableโ€ broadly. That is, the court said that a relevant statute only had to be โ€œcapable of being appliedโ€ to gun sales, not that the law needed be specifically about firearms, as other courts had held.

Whatโ€™s next

It is this interpretation that could potentially unleash a flood of lawsuits across the country.

Since many states have unfair trade practices laws like Connecticutโ€™s, it seems likely that gun violence victims will bring similar claims elsewhere. Victims are thus likely to allege that a gun manufacturerโ€™s aggressive marketing of combat-style weapons violates a state statute โ€“ like an unfair trade practice law โ€“ that is applicable to the sale or marketing of a firearm.

The fate of the Sandy Hook lawsuit and any others that follow will depend on the outcome of an all-but-certain appeal to the U.S. Supreme Court. If the court rejects the Connecticut Supreme Courtโ€™s broad interpretation of the word โ€œapplicableโ€ in the federal statue, that will restore the immunity from suit that gun makers have enjoyed for more than a decade.

However, if the top U.S. court adopts Connecticutโ€™s broad interpretation, then the gun industry can expect to be the target of a great deal more litigation in the years to come.
