It is a fact that the effects of the non-existence of limitations for the re-election of a member of parliament are widely softened by the activities of the opposition parties in parliament, as well as by the increased transparency and publicity that the democratic parliaments demonstrate through their activities. Perhaps these two conclusions identify the main reason why most constitutions foresee an unlimited possibility for re-election of members of parliament. Consecutively, we may draw the same conclusion vis-à-vis the re-election of ministers in coalition governments, contrary to homogeneous ones.
