In some specific cases, the dual voting system for persons belonging to national minorities can reconcile the requirement of providing for a reserved representation of a minority, especially if a State comes from a totalitarian experience, with the necessity of favouring the integration of the minority in the national political life. It is an example of reverse discrimination which may be justified by the history of a country, at least until the effects of the repression and of the totalitarian regime are satisfactorily (even if only partially) cancelled. It may be the only system to ensure, on the one side, that the minority has the guarantee of being represented in public affairs, and, on the other side, that the persons belonging to the national minorities are allowed, on an equal basis, to take part in the national political debate.
