- On 2013, the tribe that had the Immunity Bracelets would go to Trial, and would have the power to veto the result, and would make that decision before the votes are read. At the merge, the first contestant to win the Immunity Bracelet would be the one to have the power to veto the decision.
- On 2014, the losing tribe will vote to nominate two people to be eliminated, and the tribe that had the Immunity Bracelets would go to Trial, acting as a Jury, deciding who to eliminate. At the merge, the contesstants who were safe would act as the jury.
- On 2015, the Pre-merge Trials work the same way as last season. At the merge, the first contestant to win the Immunity Bracelet would talk to every contestant, and then will have the power to save a contestant, this person will cast the vote before the other votes are cast. Then, the contestants (including the one with the special power) will vote to nominate two people. The decision made by the contestant will be revealed, and if neither of the two nominees were saved, they would go to a tiebreaker, where they will cast out loud their vote to eliminate a contestant.

They will still have their votes, but will also have the chance to veto the result, but only before the votes are read.
- On 2017, only one tribe will win the Immunity Challenge, meaning that two tribes will attend the Trial, before the tribes can vote, both tribes will save someone from the opposing tribe, after that, each tribe will nominate someone from their team.

After the Tribe Dissolve, the safe tribe will send an emissary who will nominate a contestant from the losing tribe, also the losing tribe votes to nominate another participant. If the emissary and the tribe have chosen the same nominee, the nominee will decide the other. Both nominees will compete in a Deathly Duel, where the winner will stay, and the loser will be eliminated.
