The correct position of the law has repeatedly been stated by this court that it is straining the rule on proof of service to say that a defendant who filed a defence to the statement of claim was not served the writ of summons because there was no bailiff’s endorsement on the writ. See: Okesuyi v. Lawal (1991) 1 NWLR (Pt.176) 661, per Olatawura, JSC (of blessed memory).
