Grizzly Bear State Management Act of 2023

This bill mandates the U.S. Secretary of the Interior to reissue a 2017 rule that removed grizzly bears in the Greater Yellowstone Ecosystem from the federal endangered species list, within 180 days of the bill's enactment. It directly affects grizzly bear management in that ecosystem by reinstating state-led management authority previously established under the 2017 rule. The key provision requires the rule's reissuance without any legal challenges, explicitly stating the action "shall not be subject to judicial review."
