How did Andrew Jackson failed to enforce John Marshall's crucial decision in Worcester v. Georgia?

The famous court case "Worcester v. Georgia" was brought to the Supreme Court to decide whether it was lawful for Georgia to acquire Native American lands in a push for westward expansion. John Marshall ruled that the federal government had the authority to deal with American Indians in the way it chose, but the state of Georgia had no such right and therefore were being unlawful by invading and taking over the Native lands.
While it is cited that Jackson failed to enforce it, the ruling was much more ceremonial than anything else—an attempt to appease relations with the Native Americans while maintaining the strength and manifest destiny of the federal government.
Jackson did not send federal marshals to aid the cause of the natives, though, and he eventually continued with the removal of the Cherokees.
