Montana v. United States (1990)

Montana v. United States (1990) was a Supreme Court case that addressed whether states could regulate hunting and fishing on private lands granted to them by the federal government. The Court ruled that when the federal government grants land with specific "reserved rights," such as hunting, the state cannot impose additional regulations that interfere with those rights. In this case, Montana's attempt to regulate hunting on federal land granted to Native American tribes was limited by the terms of the federal land grant, which protected the tribes’ rights. The decision clarified the relationship between federal land grants and state regulatory authority.
