✦ Synopsis

We give an axiomatization for Qualified Majority Voting Rules where one of the alternative is socially chosen if it obtains the support of 100 • q% of the non-abstaining voters for some q ∈ ]0, 1[. These voting rules do not satisfy Neutrality in general. Instead, we introduce the axiom of Coalition Permanency.
