Chief Hilary Ezugwu & Anor. v. IGP & 6 ors unreported Suit No. FCT/HC/CV/1168/2010, the ruling of which was delivered on 31 March 2010 per Affen J (now JCA) presents a similar scenario as the instant case. In Chief Hilary Ezugwu & Anor. v. IGP & 6 Ors., a preliminary objection was raised by the defendants on grounds of non-disclosure of reasonable cause of action, and abuse of court process. Although no affidavit in support was filed, a photocopy of the writ of summons, statement of claim and allied court processes of another case, suit No. FCT/ HC/CV/1959/2009, upon which the defendants relied as the basis for alleging abuse of court process, were annexed to the preliminary objection. On the propriety of annexing court processes (or indeed any other document) to a bare notice of preliminary objection, Affen J (now JCA) held thus: “… The law, as I have always understood it, is that a party raising a preliminary point of objection who intends to rely on facts ought to file a supporting affidavit deposing copiously to those facts. It is only where the objection is predicated on grounds of law and reliance is placed on documents already before the court that no need arises for the objector to file a supporting affidavit. Like pleadings, the object of a notice of preliminary objection is to give notice to the opposing side of the case to be made which enables each party to prepare for arguments upon the issues subject matter of the objection and this saves the opposing party from being taken by surprise. See CHIEF WILSON OKOI & ORS v CHIEF IBIANG & ORS [2002] 20 WRN 146 at 155.” It seems to me that there is no hard and fast rule that a preliminary objection need be supported by an affidavit so long as enough material is placed before the trial court on which it can judicially and judiciously pronounce on the preliminary objection. Where the alleged offending writ or petition ex facie contains the relevant information against which an objection is being raised, the necessity to rely on affidavit evidence does not arise.
