In a separate decision, the Supreme Court invalidated more than 500 cases adjudicated by the National Labor Relations Board in recent years. In a five-to-four ruling, the Supreme Court said the decisions are invalid because the five-person panel only had two sitting members. NLRB nominees have been stalled in recent years by congressional in-fighting. Kimberly Freeman Brown of the group American Rights at Work said, “Hundreds of decisions in cases already decided will have to be re-opened, needlessly delaying finality for workers who were led to believe they already had it.”
