‘Thus, a respondent who has any application to make in respect of a pending appeal, can without the leave of this court, raise the objection in a Respondents’ notice in his brief of argument, and proffer argument in support of the objection, in his brief of argument, without necessarily filing a Notice of Preliminary objection, formally. The essence of indicating in the respondents’ brief of argument, a notice of Preliminary objection is to enable the appellant to respond to it in a Reply brief of argument, upon the service of the respondents’ brief of argument on the appellant. The supreme court in Charles Chikwendu Odedo v. Independent National Electoral Commission (INEC) (2008) 7 SCNJ 1 at pg.25, provided a guide as to how a preliminary objection can be raised in a brief of argument. It is to be raised under a conspicuous title or heading of “PRELIMINARY OBJECTION” followed by the grounds of the objection and supported with the argument thereon. Further see. Chief Emmanuel Osita Okereke v. Alhaji Umaru Musa Yar’Adua and Ors (2008) 5 SCNJ 1; Ralph Uwazurike v. Attorney General of the Federation (2007) 2 SCNJ 369 at P.380; Ajide v. Kelani (1985) 3 NWLR (Pt. 12) 248. I have perused the Respondents’ briefs of argument dated 14th March, 2011 and at page 3: paragraph 3.00, the NOTICE OF PRELIMINARY OBJECTION was conspicuously given therein; the grounds for the objection were also stated and thereafter the arguments on the preliminary objection were proffered by learned to the respondents. I am therefore satisfied that the notice of preliminary objection, by the respondents, is competent and I shall proceed to consider and determine it.’
