(1) The members' or delegates' assembly (party convention, general assembly) is the supreme body of a regional branch. In higher-level regional branches, this assembly is called a "party convention" and, at the lowest level, a "general assembly"; the provisions for the party convention set out below shall also apply to the general assembly. Party conventions shall convene at least once every second calendar year.
(2) Pursuant to the statutes, members of the executive committee and members of other bodies of a regional branch as well as members of the group of people defined in Article 11 (2) may be members of a delegates' assembly, but in this case the number of them eligible to vote must not exceed a fifth of the total number of assembly members.
(3) On the basis of the competence of a regional branch within the party, the party convention shall decide on party programs, statutes, subscriptions, arbitration procedures, the dissolution of the party and mergers with other parties.
(4) The party convention shall elect the chair of the regional branch, his deputies and the other members of the executive committee, the members of any other bodies that may be established and delegates in the bodies of higher-level regional branches unless the present law permits another procedure.
(5) The party convention shall receive a progress report from the executive committee at least every two years and shall pass a resolution on it. Prior to its presentation, the financial part of the report shall be verified by auditors elected by the party convention.
