If once such a right has accrued to the returned candidate or any other party to the petition, can that right be affected by the petitioner seeking to withdraw or abandon that part of his claim, viz., a claim for a further declaration that he himself or any other candidate has been duly elected ? If it were permissible for him to withdraw or abandon a part of his claim on the analogy of 0. 23, r. 1, of the Code of Civil Procedure, 79 620 he would make a virtue of necessity and withdraw or abandon that part of his claim so as to avoid any investigation in the Election Petition itself in regard to himself or any other candidate sponsored by him on any of the grounds mentioned in section 100(1) including corrupt practices within the meaning of section 123 which if proved would entail a disqualification for standing as a candidate or even for voting for a period of 6 years under sections 140 and 141(b).
