(1) That the essential formalities were not observed at the election;
(2) That the person returned did not receive the majority of legal votes at such election;
(3) That he was not qualified to be elected as such mayor or councillor, as the case may be;
(4) That he was guilty of corrupt practices prohibited by this act, either personally, or by an agent, with or without his authority, knowledge or sanction.
