A change which might appear as fundamental concerns the suppression of coalitions as allowed by the former version of the Code (apparentements: the coalition is considered as a single list in the first allocation of seats). It is unlikely that it will lead to changes in the allocation of a large number of seats. However, in a tight electoral competition, such changes could be decisive for the obtention of the majority of seats in Parliament. The requirement of special majorities for the revision of certain pieces of legislation, including the electoral law, (Article 81(1) of the Constitution) and, of course, for constitutional revision (Article 177(3)) has to be taken into consideration too. It has to be noted that, in 2017, the rule on coalitions was not applied following a consensual political agreement, so in practice no real change would take place vis-à-vis the last parliamentary elections.
