Now, an affidavit meant for use in Court stands as evidence and must as near as possible conform to oral evidence that is admissible in Court. A deponent to an affidavit is therefore to confine himself to facts and circumstances. See BAMAIYI vs. THE STATE (2001) 4 SC (PT 1) 18 at 29. Often times it is only a thin line that separates facts or circumstances which are permissible for use in an affidavit, from depositions which are legal argument or prayer or conclusion, which are not permissible for use in an affidavit. Happily, the Supreme Court per Uwaifo, JSC in BAMAIYI vs. STATE (supra) at 32-33 laid down the test to be applied as follows: “The test for doing this, in my view, is to examine each of the paragraphs deposed to in the affidavit to ascertain whether it is fit only as submission which counsel ought to urge upon the Court. If it is, then it is likely to be either an objection or legal argument which ought to be pressed in oral argument; or it may be conclusion upon an issue which ought to be left to the discretion of the Court either to make a finding or to reach a 15 decision upon through its process of reasoning. But if it is in the form of evidence which a witness may be entitled to place before the Court in his testimony on oath and it is legally receivable to prove or disprove some fact in dispute, then it qualifies as a statement of facts and circumstances which may be deposed to in an affidavit. It therefore means that prayers, objections and legal arguments are matters that may be pressed by counsel in Court and are not fit for a witness either in oral testimony or in affidavit evidence, while conclusions should not be drawn by witnesses but left for the Court to reach.”
