To obtain rescission of a default judgment under Order 9 Rule 63(1) of the High Court Civil Rules, 1971, an applicant must establish good and sufficient cause, which requires: (a) a reasonable and acceptable explanation for the default; and (b) a bona fide defence which prima facie carries some prospects of success. A consent order is not a default judgment but a final order by its nature, and to set aside such an order, fraud must ordinarily be proved. Litigants must come to court with clean hands and observe standards of truthfulness and honesty when seeking relief. Applications characterized by material non-disclosures, mala fides, or dishonesty will be dismissed, and courts may make adverse or punitive cost orders as a mark of disapproval of such conduct.
