Final answer:
The Boldt case upheld Washington State tribes' treaty rights to fish in traditional ways and retain half the catch, reinforcing tribal sovereignty.
Step-by-step explanation:
The Boldt case, formally known as United States v. Washington, upheld the tribal treaty rights of Washington State tribes. These rights included the ability to fish in their usual and accustomed ways and the right to half of the available catch in the state of Washington. This critical court decision recognized the sovereignty and rights promised to tribes in their respective treaties with the U.S., which had been frequently overlooked or violated throughout history.
While there were significant struggles for indigenous communities to have their treaty rights recognized, cases like the Boldt decision have been pivotal in affirming tribal rights and setting precedents for future negotiations over land, fishing, and the exercise of sovereignty.
