 It's been a busy couple of days at 1 First Street Northeast, Washington, D.C., the mailing address of the Supreme Court of the United States. The court has been handing down its last handful of decisions for the term. One more decision day coming on Monday. Today, though, in addition to that Chevron deference case, the justices also ruled 6-3 that city bans on homeless encampments on streets and sidewalks are not unconstitutional.
