A default judgment obtained without proper compliance with the barring procedure under Order 12 Rule 81 of the High Court Rules is erroneously granted and constitutes a nullity. Specifically, where no certificate of service is filed with the Registrar and the notice of intention to bar is not properly endorsed and filed as required by Rule 81, the defendant is not properly barred and default judgment should not be granted. For rescission under Rule 449, once the three requirements are satisfied (judgment erroneously sought or granted, judgment granted in absence of applicant, and applicant's rights affected), the applicant is entitled to succeed without the court inquiring into the merits to find good cause. While there is no specific time limit for applications under Rule 449, they must be brought within a reasonable time without undue delay, which is a question of fact determined by the explanation for delay and the circumstances of each case.
