The Zamfara debacle, and what the Electoral Act says

Section 140 of the Electoral Act, 2010 ( as amended):

140. (1) Subject to subsection (2) of this section, if the Tribunal or the Court as the case may be, determines that a candidate who was returned as elected was not validly elected on any ground, the Tribunal or the Court shall nullify the election.
(2) Where an election tribunal or court nullifies an election on the ground that the person who obtained the highest votes at the election was not qualified to contest the election, the election tribunal or court shall not declare the person with the second highest votes as elected, but shall order a fresh election.
(3) If the Tribunal or the Court determines that a candidate who was returned as elected was not validly elected on the ground that he did not score the majority of valid votes cast at the election, the Election Tribunal or the Court, as the case may be, shall declare as elected the candidate who scored the highest number of valid votes cast at the election and satisfied the requirements of the Constitution and this Act.
