Double Tribal Council

A occurs when two tribes attend tribal council in the same episode or two castaways are voted out at the same tribal council.

Formats

 * Two tribes attend tribal council on the same day and each vote a member out.
 * The two castaways who receive the highest vote totals are voted out.
 * The castaways attending tribal vote twice and two tribe members are voted out in separate vote reads (also called the Two Urns twist).
 * After one castaway is voted off, without an immunity challenge, there is another vote.

Appearances

 * There were three Double Tribal Councils in Tocantins, where one of each above format was used except for Two Urns.
 * There were two Double Tribal Councils in Vanuatu, where two tribes went to tribal council before the merge and post-auction there was a tribal with two urns.  The two urns tribal twist returned in Thailand.
 * In Philippines, there was one double tribal where one out of three tribes won immunity and two attended tribal. This made an appearance in All-Stars.
