Final answer:
In Worcester v. Georgia, the Supreme Court ruled tribal interactions were solely a federal jurisdiction, recognizing tribal sovereignty and limiting state authority.
Step-by-step explanation:
The Supreme Court ruled that only the federal court could deal with tribes in Worcester v. Georgia because the tribes were considered domestic sovereign nations. State laws, like those of Georgia, could not be enforced on Cherokee lands according to the Court's decision.
The case established that only the federal government had the authority to interact and negotiate with Indian tribes, not the states. This principle recognized the distinct political communities and sovereign rights of Native American tribes over their territories.
