Why did the Supreme Court reject the state of Georgia law for removing the Cherokee their land?

Congress passed the removal bill that May, and by September Jackson had begun negotiating with the Chickasaws, the Choctaws and the remaining Creeks to move west. Within four years they would be under land cession treaties or on the move. Some Seminoles also left in the early 1830s, and others fought the Army in Florida for several years. But Ross refused even to meet with Jackson. Instead, he turned to the U. S. Supreme Court, asking the justices to invalidate Georgia's removal law.

As the court's spring session opened in March 1831, Georgia officials roamed the Capitol to rally states' rights advocates to the idea of stripping the justices of their power to review the acts of state governments. The justices-in an act that historians would say reflected their worry over the talk coming out of Congress-ruled that they lacked jurisdiction over the Cherokees' claims against Georgia. Chief Justice John Marshall offered their only hope when he wrote that "the Indians are acknowledged to have an unquestionable ... right to the lands they occupy."
