The\ndelegates certified to have been elected as such, in the manner provided\nin this chapter, shall be conclusively entitled to their seats, rights\nand votes as delegates to such convention. When a duly elected delegate\ndoes not attend the convention, his place shall be taken by one of the\nalternates, if any, to be substituted in his place, in the order of the\nvote received by each such alternate as such vote appears upon the\ncertified list and if an equal number of votes were cast for two or more\nsuch alternates; the order in which such alternates shall be substituted\nshall be determined by lot forthwith upon the convening of the\nconvention. If there shall have been no contested election for\nalternate, substitution shall be in the order in which the name of such\nalternate appears upon the certified list, and if no alternates shall\nhave been elected or if no alternates appear at such convention, then\nthe delegates present from the same district shall elect a person to\nfill the vacancy.\n
