The correct interpretation of President Jackson's quote regarding the ruling in Worcester v. Georgia is:
John Marshall cannot force settlers not to settle on Native American lands.
This quote reflects Jackson's disdain for the Supreme Court's decision and highlights his belief that the executive branch, under his leadership, would not enforce the Court's ruling in favor of the rights of Native Americans. Jackson's statement implies that he believed the Supreme Court had no power to enforce its decisions directly, especially when they conflicted with his own policies regarding Native American affairs.
