In a unanimous decision, the Supreme Court ruled Thursday that three of President Obama‘s recess appointments to the National Labor Relations Board were invalid because they occurred during a “pro forma” session of the Senate.

While rebuking Obama, who had sought a broader power to fill vacancies due to Senate “intransigence,” the court’s majority did not adopt the more restrictive interpretation of the recess appointment power that would have limited its use to vacancies occurring only during the annual break between Senate sessions.
