In Buhari v Obasanjo (2005) 13 NWLR (Part 941) 1, when the case came to the Supreme Court on appeal, the court held that where an allegation of non-compliance with the electoral law is made, the onus lies on the petitioner firstly to establish the non-compliance, and secondly, that it did or could have affected the result of the election. It is after the petitioner has established the foregoing that the onus would shift to the respondent whose election is challenged, to establish that the result was not affected.
MEANING OF NON-COMPLIANCE WITH REGARDS TO ELECTION
Construing the word “non-compliance” in both provisions with regard to an election has created a situation where an election has been conducted in a manner not in accordance with the provisions of the Act and/or the guidelines prescribed therefrom.
