The Code of Good Practice in Electoral Matters details the various aspects of equal suffrage, which is one of the principles of the European electoral heritage. Equal suffrage entails inter alia:

“2.1. Equal voting rights: each voter has in principle one vote; where the electoral system provides voters with more than one vote, each voter has the same number of votes (one person – one vote principle in the narrow sense).

2.2. Equal voting power: seats must be evenly distributed between the constituencies.”
