Worcester v Georgia is an example of Jackson's expansion of presidential power over the authority of the Supreme Court and injustices perpetuated against Native Americans.
Worcester v Georgia was a Supreme Court case in which Chief Justice John Marshall determined that states had no jurisdiction over Native American lands. The state of Georgia forbade any non-Indian from living on Indian lands. Worcester lived in Cherokee territory by permission of the Cherokees, so he sued for the right to continue living on the reservation. John Marshall's opinion was that the Cherokee held their lands from a treaty with the United States, and as non-citizens under treaty they were immune to US laws.
