Rational choice theories of politics
'If Option 1 is ranked higher than Option 2, then removing Option 3 should not alter the relative rankings of Options 1 and 2', this is the definition of which property of fairness?
Three sets of voters pick between three candidates:

30% prefer A to B to C

40% prefer B to C to A

30% prefer C to A to B

Suppose only the first choice counts, so B wins the election.

However, if C was removed, A would win the election 60% to 40%.

This is an example of violation of which principle?
