#REDIRECT[[Greatest possible consensus criterion#Unanimous consensus criterion]]
==Definition==
A [[voting system]] that guarantees the [[election]] of an alternative that is [[consented]] to by all voters in the voting population satisfies the [[unanimous consensus criterion]].
An alternative that is consented by all voters is called a [[unanimous consensus winner]]. In a given election with two or more alternatives, there can exist more than one unanimous consensus winner. Voting systems that guarantee the election of a unanimous consensus winner must have a tie-breaking mechanism among multiple winners in order to be decisive.
[[Approval voting]] and [[Llull voting]] satisfy the unanimous consensus criterion. [[Condorcet methods]], [[Plurality voting]], [[IRV]], and the [[Borda count]] do not satisfy this criterion.
