The binding legal principles established are: (1) Service of process effected by delivery to a responsible person at the defendant's chosen domicilium citandi et executandi constitutes proper and effective service under Order 5 rule 39(2)(b) of the High Court Rules, 1971, even without personal service on the defendant; (2) A Sheriff's Return of Service constitutes prima facie proof of service which must be rebutted by the party challenging service; (3) For upliftment of automatic bar, an applicant must satisfy all five requirements from Smith N O v Brummer N O, including providing reasonable explanation for delay, demonstrating bona fides, showing no reckless disregard of rules, establishing a case not obviously without foundation, and showing no irremediable prejudice to the other party; (4) Allegations of forgery must be supported by credible evidence such as police reports, admissions by the alleged forger, or expert evidence - bare unsupported allegations are insufficient to discharge the evidentiary burden.
