Challenges to the controversial "Waters of the United States" rule should be heard by federal district, rather than appellate, courts, the U.S. Supreme Court said in a unanimous decision.
The decision, issued on Jan. 22, adds a layer of uncertainty to the Obama-era rule, which has been stayed by a federal appeals court since 2015, but could now go into effect before the Trump administration has a chance to rescind and replace it, though that is unlikely.
