The Jury

The Jury was introduced in Big Brother 2. The final seven evicted houseguests, not including the Final 2, are members of The Jury. They vote for the winner of Big Brother. Up until Big Brother 4, all the evicted houseguests voted for the winner of Big Brother. The Jury became only the final seven (not including the Final 2) houseguests because in Big Brother 3, Danielle Reyes lost the season because of her Diary Room confessions. Thus, The Jury and the Sequester House were born. In Big Brother 15 and Big Brother 16, it was changed back to a jury of nine.

The Jury House
Each member of the Jury lives the remainder of the Big Brother game in total seclusion, arriving in an undisclosed location, usually a tropical and beautiful house. They have access to movies and games, a pool, and (depending on the location) a private beach. They are not allowed communication with the outside world so that their votes are not tainted by behind-the-scenes information, such as secret alliances or betrayals that they may not be aware of.

The Jury stays privy to house happenings in the form of a DVD brought along with the most recent evicted houseguest, showcasing competitions and other group activities. Secret meetings, Diary Room sessions, and other happenings that do not include the entire group of remaining houseguests are not disclosed.

In Big Brother Canada 1, Big Brother 15, and Big Brother 16, the jury members got a chance to return to the game. Big Brother Canada had a public vote, while Big Brother 15 had a competition. It has not yet been announced how the season 16 jury member will return.

Voting
On finale night, each juror casts a vote for whom they would like to see be the winner of Big Brother. The votes are the names of the Final 2 written on a key, which the juror places in the nomination box. In the same form of a Nomination Ceremony, the keys are removed one at a time, revealing the winner of the season.

Trivia

 * Big Brother 2 would have also had 10 jurors if Justin Sebik had not been expelled.
 * In Big Brother 2, the final two were given the option to nullify two jury votes (one per finalist), making it the first and so far only time in Big Brother history that two jury votes were negated.
