In first half of 19th century Cherokee efforts to retain their tribal lands in Georgia received support from who?

Chief Justice John Marshall, personally, supported the Cherokee efforts to retain their land, but never had an opportunity to write a legal decision supporting his beliefs. Marshall expressed his opinion that the US government owed the Cherokee protection from Georgia in his opinion in Worcester v. Georgia, (1832), but this was not part of the legal ruling because the United States wasn't party to the case.
