In the case of Worcester v. Georgia, the Supreme Court ruled that Georgia's laws had no force within Cherokee territory, and that the Cherokee Nation was a "distinct community" with its own laws and rights. However, President Andrew Jackson famously defied the Supreme Court's ruling and refused to enforce it.
In my opinion, Jackson should have followed the Supreme Court's decision and enforced it. The Supreme Court is the highest court in the United States, and its decisions are binding on all other branches of government. By refusing to enforce the Court's ruling, Jackson was essentially undermining the authority of the judicial branch and setting a dangerous precedent for future presidents to ignore Supreme Court decisions they disagree with.
One potential action Jackson could have taken to enforce the Supreme Court decision would have been to use the power of the federal government to protect the Cherokee Nation from Georgia's attempts to assert its authority over them. For example, he could have sent federal troops to protect Cherokee lands and prevent Georgia from encroaching on their territory. Additionally, he could have worked with Congress to pass legislation recognizing the Cherokee Nation's sovereignty and protecting their rights.
Overall, Jackson's failure to enforce the Supreme Court decision in Worcester v. Georgia was a significant blow to the authority of the judiciary and the rule of law, and it set a precedent for future presidents to disregard court decisions they disagreed with.
