Coalition pacts must adhere to rules on formation of alliances

Article 10 of Political Parties Act (PPA) provides that, two or more political parties may form a coalition before or after an election and shall deposit the coalition agreement with the Registrar of Political Parties.

Although according to this article, a coalition agreement entered into before an election shall be deposited with the Registrar at least three months before that election; it is implied that that agreement can be amended with addenda where necessary.
