 The Wisconsin Supreme Court in State v. Sanapaw held that the treaty rights were terminated by Congress . In analyzing the case , the Wisconsin Supreme Court first had to determine whether the tribe had hunting and fishing rights under treaties with the United States . It found that although the Wolf River Treaty did not specifically mention hunting and fishing rights , the term " to be held as Indian lands are held " was clear . Indians have always been able to hunt and fish on their own land , and if a term in a treaty with Indians is ambiguous , the Wisconsin Supreme Court found that it must be resolved in favor of the tribe . Since the tribe originally had hunting and fishing rights under the treaty , the Wisconsin Supreme Court then looked to determine whether Congress had removed those rights by enacting the Menominee Termination Act . The Wisconsin Supreme Court held that Congress had used its plenary power to abrogate those rights .
