The binding legal principles established are: (1) The proviso to Rule 238(2a) of the High Court Rules does not alter the immutable rule that a respondent represented by a legal practitioner must file heads of argument within 10 days of being served with the applicant's heads - the proviso only applies to specific scenarios such as where applicant's heads are served near the hearing date, where a previously unrepresented respondent obtains representation, or where an unrepresented litigant chooses to file heads. (2) In applications for upliftment of automatic bar under Rule 238(2b), where a party blames their legal practitioners or law officers for the default, supporting affidavits from those practitioners/officers must be filed, otherwise the application will be dismissed. (3) Mere assertion that a default was not wilful is insufficient without full disclosure of all relevant facts including dates, names, and circumstances. (4) When respondents remain barred, the application proceeds as unopposed in terms of Rule 238(2b).
