In Okpa v. Irek & Anor. [2012] LPELR-8033 (CA) held thus: This court has consistently held that a witness statement on oath is different from affidavit evidence. An affidavit is a statement of fact which the maker or deponent swears to be true to the best of his knowledge. It is a court Process in writing deposing to facts within the knowledge of the deponent. It is documentary evidence which the court can admit in the absence of any unchallenged evidence. Akpokeniovo v. Agas [2004] 10 NWLR (Pt. 881) 394. On the contrary a witness statement is not evidence. It only becomes evidence after the witness is sworn in court and adopts his witness statement. At this stage at best it becomes evidence in chief. It is thereafter subjected to cross examination after which it becomes evidence to be used by the Court. If the opponent fails to cross examine the witness, it is taken as the true situation of facts contained therein.
PARTY IS TO SHOW HOW THE PARAGRAPHS OF AN AFFIDAVIT ARE INCONSISTENT WITH THE EVIDENCE ACT
However, where a party alleges that certain paragraphs offend the provisions of Section 115(2) of the Evidence Act, the responsibility is on that party to explain how the paragraphs of the affidavit are inconsistent with the section of the Evidence Act. It is not enough for a party to allege that certain paragraphs are inconsistent with the provisions of the Evidence Act. Learned counsel for the Respondent has failed to explain how paragraph 8 (c) and (d) constitute argument and conclusion. I therefore discountenance learned senior counsel’s argument on that score.
