Supreme Court keeps ruling that let TSA require masks for COVID-19 pandemic

The Supreme Court allowed a lower court ruling to stand that permitted the Transportation Security Administration to require masks by passengers on airlines and trains during the peak of the COVID-19 pandemic.

The high court's order follows a December ruling by the U.S. Court of Appeals for the D.C. Court that held that the TSA had the authority to enforce such requirements during times of national emergencies.

California lawyer Jonathan Corbett, who brought the case to the Supreme Court, was asking the justices to declare the appeals court decision as moot but ultimately lost on Monday when the high court kept the December ruling in place.
