This joint resolution seeks to block a rule issued by the National Marine Fisheries Service on April 5, 2024, that addresses how the federal government lists endangered and threatened species and designates their critical habitats. The resolution uses the Congressional Review Act, a procedure that allows Congress to disapprove and overturn federal agency rules. If passed, the rule would be invalidated and have no legal effect. The resolution was introduced by a group of Republican senators and was referred to the Senate Committee on Commerce, Science, and Transportation. No specific funding or implementation timeline is mentioned in the resolution itself, as it is solely designed to prevent an existing regulation from taking effect.
