The U.S. Supreme Court is allowing survivors and relatives of victims of the Sandy Hook Elementary School shooting to pursue their lawsuit against Remington Arms Co., the manufacturer of the rifle used to kill 26 people.

Supreme Court justices debated Monday how much leeway to grant airlines in reporting security threats that are eventually proven false, USA Today reports. The case involves Air Wisconsin Airlines, which argued that it deserves the same immunity from lawsuits as it granted the Transportation Security Administration, the article says. The airline had lost a $1.4 million defamation case after reporting that a pilot, William Hoeper, was “mentally unstable” and could be armed as a passenger on a flight after he failed a simulator test.
