General requirements for mergers
Registered political parties may merge with each other subject to the following rules:
a) There must be a merger pact singed jointly by the representatives of the political parties involved. This pact must be approved by the highest-ranking governing body of each of them and should have the support of an absolute majority of all members.
b) Once the merger has been agreed, the chairman of each of the higher executive committees of the parties involved therein shall jointly request the head of the Electoral Registry in writing to register the merger pact, which should be annexed thereto duly registered. This registration shall be granted subject to verification of the legal requirements.
c) Mergers can be concluded between parties of different levels and scope, at the national level, in one or more provinces and in one or more cantons, provided that the requirements relating to the formation, registration and functioning of political parties are complied with according to the level in question.
