The Supreme Court on Monday sided with a member of the Crow tribe who was fined for hunting elk in Wyoming's Bighorn National Forest, giving him a good chance to get a more than $8,000 fine against him overturned.

The case the justices decided 5-4 is a win for Clayvin Herrera and his tribe, which had argued they had hunting rights in the forest.

Herrera's case began in 2014 when he went hunting with family. The group began on the Crow tribe's reservation in southern Montana but crossed into the neighboring Bighorn National Forest in Wyoming, where they killed several elk.

Soon after, a game warden saw photos Herrera posted on a bragging website for hunters, including one of him crouched in the snow behind an elk he shot and another with its antlers balanced on his shoulders. The game warden ultimately identified the area where the photos were taken in the Bighorn National Forrest, and Herrera was cited for killing an elk there during the winter, when it is prohibited.

But Herrera, backed by the federal government, argued that when his tribe gave up land in present-day Montana and Wyoming under an 1868 treaty, the tribe retained the right to hunt on the land, including land that became Wyoming's Bighorn National Forest.

The state of Wyoming had argued that the Crow tribe's hunting rights ceased to exist after Wyoming became a state in 1890 or after Bighorn National Forest was established in 1897. But the Supreme Court disagreed, with Justice Neil Gorsuch joining his four liberal colleagues - justices Ruth Bader Ginsburg, Stephen Breyer, Sonia Sotomayor and Elena Kagan - in ruling for Herrera.

The court's four other justices said they would have ruled that a prior case settled that Crow tribe members like Herrera don't have an unrestricted right to hunt and fish in the Bighorn National Forest and are subject to the game laws of Wyoming.
