Final answer:
The United States Supreme Court ruled in the Downes v. Bidwell case that the Constitution does not necessarily apply in full to newly acquired territories.
Step-by-step explanation:
In the Downes v. Bidwell case, the United States Supreme Court ruled in 1901 that the Constitution does not necessarily apply in full to newly acquired territories. The Court held that territories could be governed by Congress with a different set of rights for their inhabitants. This decision was based on the idea that territories were not fully incorporated into the United States and did not have the same rights as states.
