Great Ogboru versus Emmanuel Uduaghan
Nov. 9, 2010
A COURT of Appeal sitting in Benin, the Edo State capital, annulled the election of Delta State governor, Dr Emmanuel Uduaghan.

The appellate court subsequently ordered fresh elections in the state within  90 days.
The decision followed the appeal brought by Great Ogboru against Governor Emmanuel Uduaghan, the current governor of the state. The appeal panel earlier dismissed the petition brought by AC candidate, Okocha, where he sought the nullification of Uduaghan’s election because of his exclusion from the 2007 election by INEC.

In its judgment, delivered on July 9, 2009 which formed the basis of the appeal, The Retrial Election Petition Tribunal, Asaba dismissed the petition filed by Great Oghoru. The tribunal however held that INEC had no power to exclude any candidate from contesting an election provided such candidate was validly nominated by his party.

In its unanimous judgment, the tribunal held that “the fact that one has been nominated by his party does not constitute a valid nomination. It is clear that valid nomination by a political party goes beyond nomination of a candidate by a political party. To be validly nominated, a candidate must show that he has complied with all the statutory provisions related to the nomination that qualifies him to become a valid candidate in the election.

It is the contention of the respondent that the petitioner has not proved that he complied with the provision of sections 187 sub-section 1 of the 1997 Constitution.

Oyinlola vs Aregbesola

THE Court of Appeal sitting in Ibadan, the Oyo State capital, sacked the Peoples Democratic Party, PDP, candidate, Governor Olagunsoye Oyinlola and declared the candidate of the Action Congress of Nigeria, Engineer Rauf Aregbesola as winner of the April 14, 2007 elections.

Aregbesola’s prayer was for the court to nullify the governor’s election and declare him (Aregbesola) as the duly elected governor, having scored the majority of the lawful votes cast. Categorically he is calling for the nullification of the results of the governorship election in 10 local government areas of the state.

The local governments are Boripe, Boluwaduro, Ifedayo, Odo Otin, Ayedaade, Isokan, Ife East, Ife South, Atakumosa West and Ife Central.

Aregbeola based his argument on alleged substantial non-compliance with mandatory provisions of the 2006 Electoral Act, malpractices and violence which he claimed substantially affected the validity of the said election.
