 The federal rule promulgating the national oceanic and atmospheric conditions requiring the fishermen to pay $700 a day for an at-sea monitor is out of bounds. The justices in January heard the arguments. Now they rule. The court's decision reels in what's now known as the Chevron Doctrine, a legal theory established in the 1980s that says if a federal regulation is challenged, the court should defer to the agency's interpretation of whether Congress granted them the authority or not.
