The chairman and secretary of the caucus shall, at said time and place, recount said ballots and determine the questions raised. Each candidate affected may be present during such recount, or may be represented by an agent appointed by him in writing. If it shall appear upon a recount that persons were nominated or elected other than those declared to have been nominated or elected, certificates of such change shall be made in the manner provided in section five as to an original certificate.
Any presiding officer, secretary or clerk of a caucus who wilfully neglects or refuses to comply with the provisions of this section shall be punished by a fine of not more than five hundred dollars or by imprisonment for not more than six months.
