Section 6-126 - Conventions; rules for holding1. The time and place of meeting of a convention shall be fixed, within the times prescribed herein, by a committee appointed pursuant to the rules of the state committee. The room designated for the meeting place of a convention shall have ample seating capacity for all delegates and alternates. Every convention shall be called to order by the chairman of the committee from which the call originates or by a person designated in writing for that purpose by such chairman, or, if he fails to make such designation, then, by a person designated in such manner as the rules of the party shall prescribe. Such chairman or person designated shall have the custody of the roll of the convention until it shall have been organized. No such convention shall proceed to the election of a temporary chairman or transact any business until the time fixed for the opening thereof nor until a majority of the delegates or respective alternates named in the official roll shall be present. The roll call upon the election of a temporary chairman shall not be delayed more than one hour after the time specified in the call for the opening of the convention, provided a majority of delegates, including alternates sufficient to make up such majority by substitution, are present. The person who calls the convention to order shall exercise no other function than that of calling the official roll of the delegates upon the vote for temporary chairman and declaring the result thereof.2. The temporary chairman shall be chosen upon a call of the official roll. The committees of the convention shall be appointed by the convention, or by the temporary chairman, as the convention may order. Where only one candidate is placed in nomination for any office, the vote may be taken viva voce. When more than one candidate is placed in nomination for an office the roll of the delegates shall be called and each delegate when his name is called shall arise in his place and announce his choice, except that the chairman of a delegation from any unit of representation provided for by party rules, unless a member of such delegation objects, may announce the vote of such delegation. The convention may appoint a committee to nominate candidates to fill vacancies in nominations made by the convention and caused by the death, declination or disqualification of a candidate. The permanent officer shall keep the records of the convention.
