The Principles of Majority and Proportionality

It is only in connection with electoral law that the terms ‘majority principle’ and ‘proportionality’ are widely used. It seems to us meaningful to apply the two concepts also to the political decision-making process as a whole. In this broadened sense ‘majority principle’ and ‘proportionality’ denote certain models of conflict regulation. The majority model then denotes the regulation of conflict through majority decisions. The proportional model is much more difficult to describe: its basic characteristic is that all groups influence a decision in proportion to their numerical strength. Proportional conflict regulation is easiest to apply when a decision is concerned with several units, all of which are perceived as equivalent to one another. The classical case of this is the parliamentary election, for the parliamentary seats are perceived as equivalent to one another, so that by means of an appropriate electoral law they can relatively easily be distributed on a proportional basis among the different political groups. In Switzerland the election of the government by the parliament gives rise to an analogous situation, in that the seven seats in the Bundesrat (Federal Council) are perceived as equivalent to one another, so that they can likewise be relatively easily distributed on a proportional basis. In most other political systems the application of the rules of proportionality at the level of the government would entail greater difficulties, since the individual governmental posts are perceived as being of different value. The greatest difficulty presents itself when only a single office is to be filled, for example that of President. Here the application of proportional rules is only possible if rotation of office (i.e. proportionality in the temporal dimension) is brought into the reckoning, or if the disadvantage imposed on one group can be compensated by preference given to it in another decision.
