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.
AFFIDAVIT NOT DENIED OR POSITIVELY CONTROVERTED IS DEEMED ADMITTED
The law is now quite clear on the fact that, an affidavit not denied or positively controverted, is deemed to be admitted by the adverse party. And to deny an affidavit, the adverse party does not have to speak in tongues or in subterfuge, as he is required to deny the averment frontally and positively, leaving the court or any reader of his denial not in doubt of his adverse position to the one advanced or canvassed in the supporting affidavit. See the case of Hon. Maryati Audu Dogan & Ors. vs. A.G. Taraba State, an unreported decision of this court in CA/J/243/2010, delivered on 25/5/2011, pages 35 – 36 thereof. It is settled law that an affidavit evidence constitutes evidence and any deposition not challenged is deemed admitted. H.S. Engineering Ltd. vs. A.S. Yakubu Ltd.
