This is why the Venice Commission rapporteurs had recommended enshrining in the Constitution only the main principles of the electoral system, in order to ensure the necessary flexibility in the future development of that system. Many details have thus been removed from Article 89. Yet, the possibility of a second round between the two most voted parties of alliances is mentioned, which gives a binding framework for the adoption of a certain type of proportional electoral system. In reality, the electoral system is thus enshrined to a large extent in the Constitution. Paragraph 4 of Article 89 should be removed; the possibility of a second round should be regulated in the Electoral Code.
