Justices Leave Texas Court Ruling In Place, Allowing Case To Move Forward To Trial The Supreme Court on Monday turned away Boeing’s attempt to stave off a lawsuit over its 737 Max aircraft brought by the Southwest Pilots Association (SWAPA) union. Boeing had argued the lawsuit is preempted by federal law. The SWAPA urged the Supreme Court to turn away the appeal. It stressed the lower ruling was correct but also argued it is a “factually atypical” case that didn’t warrant the justices’ attention. “Whatever preemption question this case may raise-which SWAPA contends is none-it is of no serious interest outside of this proceeding,” the court wrote. “Boeing’s claims about alleged ‘havoc’ flowing from this litigation are not-well-founded.”
