Unanimity

The unanimity principle is a Voting Theory principle. Unanimity means "agreement reached by all people".

Using Voting Theory Relations for $N = 2$ we define Unanimity as:

• if $x \ P_1 \ y$ and $x \ P_2 \ y$ then $x \ P \ y$
• or $x$ is globally preferred to $y$ if both voters vote for $x$

It follows from two principles

If a candidate $a$ is always preferred by the majority to $b$, then we can say that $b$ is dominated by $a$ and never consider $b$ again

Dominance

The same concept in different disciplines is also often called Dominance
