Though the phrase separation of powers appears nowhere in the text of the Constitution, the Supreme Court has recognized separation of powers as a constitutional principle in cases throughout the nation’s history.

Loper Bright Enterprises v. Raimondo and Relentless, Inc. v. Department of Commerce involved whether the National Marine Fisheries Service (NMFS) properly interpreted the Magnuson-Stevens Fishery Conservation and Management Act (MSA). The MSA delegates regulatory authority over fisheries to the Secretary of Commerce, who in turn has delegated authority to NMFS to administer the statute. An MSA provision permits NMFS to require commercial fishing vessels to carry federal observers. The MSA expressly provides for vessels to cover the cost of these observers in three specific circumstances, but does not otherwise provide that vessels will cover the cost of observers. Another MSA provision authorizes any regulations deemed necessary and appropriate for the conservation and management of the fishery. NMFS issued a regulation generally requiring vessels to pay a per diem fee to federal observers where funds have not been appropriated to cover the observers’ costs.
Loper Bright Enterprises v. Raimondo, 603 U.S. ___ (2024), is a landmark decision of the United States Supreme Court in the field of administrative law, the law governing regulatory agencies. Together with its companion case, Relentless, Inc. v. Department of Commerce, it overruled the principle of Chevron deference established in Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc. (1984), which had directed courts to defer to an agency's reasonable interpretation of an ambiguity in a law that the agency enforces.
