Under cross-examination, DW3 admitted that he signed his deposition in the chambers of his counsel. However, there is no evidence before me that DW3 did not present himself before the Commissioner for Oaths to be sworn. The name and signature of the Commissioner for Oaths is on the deposition together with the date it was sworn. There is therefore a presumption of regularity in the statement on oath by virtue of Section 168 of the Evidence Act 2011. See Auta v Olaniyi  4 NWLR (Pt 863) 394.
