In March, the Connecticut Supreme Court put the gun industry on notice: If you advertise your weapons as alluring tools for mass slaughter, you will face consequences—at least in this state.

By a 4–3 vote, the court revived a lawsuit by the families of Sandy Hook victims alleging that Remington recklessly marketed its Bushmaster AR-15–style weapon for “illegal, offensive purposes,” contributing to Adam Lanza’s murder of 26 people at their elementary school. The majority ruled that a federal law does not shield Remington from liability for wrongful advertising, permitting a jury to determine whether Remington can be held liable. Its decision is a stunning blow to the firearms industry, which has long claimed near-absolute immunity from such lawsuits. And it allows the plaintiffs to uncover private, potentially damning communications that will reveal how Remington peddles its lethal products to the public.

That case was appealed to the U.S. Supreme Court.

Today, SCOTUS decided NOT to review the case, in essence letting the case go forward.
