The Supreme Court in Omega Bank (Nig) Plc v. O.B.C. Ltd. [2005] 8 NWLR (Part 928) 547 at 587 Paragraphs C – D per Tobi, JSC (as he then was) the Apex Court held inter alia that: “… It is my view that where a document is not signed, it may not be admitted in evidence. Even if it is admitted in evidence, the Court should not attach any probative value to it. This is because a document which is not signed has no origin in terms of its maker….at page 582 Paragraph A, His Lordship, Tobi, JSC of blessed memory further emphasized that:” A document which is not signed does not have any efficacy in law. As held in the cases examined, the document is worthless and a worthless document cannot be efficacious…”
COURT WILL EXPUNGE INADMISSIBLE EXHIBIT RECEIVED IN EVIDENCE
The law is that where a Court has received evidence that is inadmissible, the proper thing is to expunge such evidence from the records; see Zenith bank Plc v. Ekereuwem (2012) 4 NWLR (Pt. 1290) at 213 214. Consequently, I make an Order expunging Exhs. PW1-A1 PW1-A7 from the record of this Court in this case.
