Supreme Court Justice Neil Gorsuch broke with conservatives and joined four other liberal justices in a 5-4 tribal rights decision Monday.

The Supreme Court upheld a Native American man’s hunting rights under a 150-year-old treaty. Crow tribe member Clayvin Herrera was charged in 2014 for off-season hunting in the Bighorn National Forest in Wyoming but argued that a treaty signed in 1868 between the tribe and Wyoming allowed him to hunt any time of the year.
