It could also chart a legal road map for the survivors and relatives of victims in other mass shootings as they pursue accountability. "Your job is to make and sell a product to prevent that from happening". It's not American capitalistic business practice as we know it. "And the courtship between Remington and Adam Lanza is at the heart if this case".
The statute, backed by the National Rifle Association, has helped the industry defeat similar cases, with the Sandy Hook suit perhaps the highest-profile example.
The company's lawyer, James Vogts, argued otherwise. They're seeking to reinstate a lawsuit against the manufacturer of the military-style weapon used in the attack.
A week ago, 26 people were fatally shot in a church in Sutherland Springs, Texas, and a month earlier, a gunman sprayed gunfire over a crowd attending an outdoor music festival in Las Vegas, killing 59 people.
Some argue that the recent massacres, serving as a reminder of the toll weapons like the one used in Newtown can have, could lend credence to the lawsuit's claims.
The Sandy Hook case hinges on an exception to the federal immunity law that applies when a seller "negligently entrusts" a weapon to a buyer who is likely to use it in a crime.
But moves to even modestly tighten gun control laws floundered and a lawsuit brought by some families of the victims against the manufacturers of the semi-automatic gun used in the crime was thrown out by a judge past year.

The system requires the president to work with military aides and give orders that must be followed down a chain of command. Mr Kehler admitted: "I don't know". "But you'd have a real constitutional crisis on your hands if that occurred", he said.
Lawyers for the family members asked the court to revive the suit that was dismissed past year by Judge Barbara Bellis in Bridgeport, Connecticut. "This action falls squarely within the broad immunity provided by PLCAA". The families' lawsuit alleges that the company should have known that mass shootings might occur as a result of selling such rifles to civilians.
President Barack Obama cried as he spoke about the youngest victims but he failed to get bipartisan support for gun reforms. Negligent entrustment is specifically excepted from the 2005 gun maker shield laws.
Lawmakers behind the measure cited a need to foil what they described as predatory and politically driven litigation. But defense attorneys contend that the exception is used for gun sellers, not manufacturers.
Lanza, 20, used a Remington AR-15 Bushmaster rifle, a semi-automatic civilian version of the US military's M-16, to kill 20 school children between the ages of 6 and 7, as well as six adult staff members, at Sandy Hook Elementary School in Newtown, Connecticut, on December 14, 2012.
Families of victims in the Sandy Hook school shooting are taking their fight against a major gunmaker to the Connecticut Supreme Court on Tuesday.
United States corporations, argued the plaintiffs, have a duty to look out for public safety.
