Why should Andrew Jackson have been impeached?

The only thing he did that he could have been impeached for is the forced removal of the Cherokee Indians from their native lands, known as the "Trial of Tears", which went against the Supreme Court's decision.

The US Supreme Court never banned the government from removing Native Americans from their land. Chief Justice John Marshall opposed the idea and expressed his personal opinion on the subject several times; however, the United States was never party to a suit that would allow Marshall to make a legal ruling on the matter.

Two cases, Worcester v. Georgia, (1832), and Cherokee Nation v. Georgia, (1831), appear to be the source of much confusion.

The Supreme Court dismissed Cherokee Nation v. Georgia, (1831), for lack of original (trial) jurisdiction over the case; therefore, nothing Marshall wrote was binding on any party.

In Worcester v. Georgia, (1832), the only legal decisions were that the State of Georgia had no right to regulate use of Cherokee land, and that the state had to release some missionaries who were imprisoned for living on Cherokee property without holding a state license to do so. In Worcester, Marshall stated the federal government should protect the Cherokee from Georgia's hostilities, but he lacked jurisdiction to make the opinion part of the legal decision because the United States wasn't party to the case.
