Erik Moberg ã:
A Theory of Democratic Politics


A parliamentary system depends, as we have seen in part 5.3, for its proper functioning on cohesive, disciplined political parties. Therefore some constitutional elements or constructions, which from a logical point may seem possible are, nevertheless, destructive in real politics.

First, it is important that the proportional technique used for appointing the legislators is of a pure list character, or at least rather close to that. A system without any lists at all such as the Finish system described in part 5.2 is hardly useful in a purely parliamentary setting. The reason, of course, is that it may be difficult for the party leaderships to maintain party discipline within such a system (as explained in part 6.3).

Second, it is important that the popular techniques of primaries, referendums and initiatives are not frequently used. The reason is that these techniques, as explained in part 6.6, are detrimental to party discipline. Still, and in some particular and rare cases, referendums may be used for upholding party discipline, as is also mentioned in part 6.6.
