The Jury

The Jury consists of a group of eliminated castaways (typically past the merge portion of the competition) that return to witness the remaining castaways' actions at Tribal Council. The information they take in from these visits is supposed to help them decide who to vote for to win the title of Sole Survivor. They are usually forbidden to speak, with the exception of the Final Tribal Council, where they are allowed to address the finalists and ask them questions. The Jury is typically comprised of seven to nine members, but this can vary.

Jury Tiebreakers
In the case of a tie in a Final Two, the last pre-jury member sends in a tiebreaker vote. In the event of a tie in a Final Three, the finalist with the least votes along with anyone who voted for them would break it between the tother two finalists. However, in a Final Three if the vote is deadlocked (3-3-3) then there would be a competition between the final three to eliminate a juror. Then the finalist who loses a vote along with their two voters revote.
