A unanimous Supreme Court decision Thursday invalidating President Obama’s recess appointments to the National Labor Relations Board may send more than 1,000 decisions back to go, including several Minnesota cases.

The high court’s ruling in NLRB v. Canning means the NLRB did not have a legal quorum, effectively invalidating labor decisions by illegally appointed panels, on hold since the Supreme Court took up the case.

The resulting backlog of NLRB cases includes 333 published decisions and 725 unpublished decisions spanning January 4, 2012 to Aug. 4, 2013, according to an analysis by former NLRB board member John Raudabaugh.
