Council of Three

From Tardis Wiki, the free Doctor Who reference

The Council of Three was the ruling body of the Kulan. The Council was made up of a member from each discipline with the third a priest from the Kulan religious order. The council present in 2001 for the invasion of Earth was relatively new because the old leaders had died with half the invasion fleet on a failed attack on a Chelonian colony.
