The correct response is: It ignored the fact that Native American lands were sovereign and not technically part of the United States.
The Worcester v. Georgia decision in 1832 ruled that the state of Georgia could not impose its laws within the boundaries of the Cherokee Nation, recognizing the sovereignty of Native American nations. The Indian Removal Act of 1830, however, facilitated the forced removal of Native Americans from their lands, directly contradicting the recognition of their sovereignty established by the Court.
