The U.S. Supreme Court is about to take up Noel Canning v. National Labor Relations Board, perhaps better known as "that case about recess appointments". The issue is the interpretation of Article 2, Section 2, Clause 3 of the U.S. Constitution,
The President shall have Power to fill up all Vacancies that may happen during the Recess of the Senate, by granting Commissions which shall expire at the End of their next Session.
This case is rich in linguistic issues: The scope of of the prepositional phrase "during the recess of the Senate"; what "the recess" means; what "happen" means, and so on. There's some earlier LL discussion in "What 'the' means", 1/28/2013; no doubt there will be more to say after the oral arguments in this case, and especially when the decision is announced.
