I return to section 146(1) of the Electoral Act. The third word in the section is “shall”. It is an obligatory and mandatory word conveying a command and compulsion. It is peremptory in nature and content. It is a word of authority imposing a duty mostly on an unnamed person. Courts of law mostly interpret the word in the above context of authority and command; bereft of discretion. (See Achineku v Ishagba (1988) 4 NWLR (Part 89) 411; UNTHBM v Nnoli (1994) 8 NWLR (Part 363) 376; Lt.-Gen Bamaiyi (Rtd) v Attorney-General of the Federation (2001) 12 NWLR (Part 727) 468; Ogidi v The State (2005) 5 NWLR (Part 918) 286). Although the word could, at times, convey a permissive meaning, like “may” it is my view that it conveys its usual and ordinary meaning of obligation and command in section 146(1).
