New Jersey Statutes Title 19. Elections 19 § 29-1

a. Malconduct, fraud or corruption on the part of the members of any district board, or of any members of the board of county canvassers, sufficient to challenge the result;

b. When the incumbent was not eligible to the office at the time of the election;

c. When the incumbent had been duly convicted before such election of any crime which would render him incompetent to exercise the right of suffrage, and the incumbent had not been pardoned at the time of the election;

d. When the incumbent had given or offered to any elector or any member of any district board, clerk or canvasser, any bribe or reward, in money, property or thing of value for the purpose of procuring his election;

e. When illegal votes have been received, or legal votes rejected at the polls sufficient to change the result;

f. For any error by any board of canvassers in counting the votes or declaring the result of the election, if such error would change the result;

g. For any other cause which shows that another was the person legally elected;

h. The paying, promise to pay or expenditure of any money or other thing of value or incurring of any liability in excess of the amount permitted by this title for any purpose or in any manner not authorized by this title;

The term “incumbent” means the person whom the canvassers declare elected or the person who is declared elected as a result of a recount; but in the case of a tie vote as a result of the canvass or recount, either party may contest the election, in which case the term “incumbent” means the person having an equal number of votes with the contestant.
