The BIA's goal to protect domestic and dependent nations, was reaffirmed by the 1831 court case Cherokee Nation v. Georgia. The Supreme Court originally refused to hear the case, because the Cherokee nation was not an independent state and could not litigate in the federal court. It was not until the court case Worcester v. Georgia, when Chief Justice John Marshall allowed Native American tribes to be recognized as "domestic dependent nations." These court cases set precedent for future treaties, as more Native tribes were recognized as domestic and dependent nations.
