1. Under Rule 63(3) of the High Court Rules, a party is presumed to have knowledge of a default judgment within two days of its issuance, and the burden is on the party to adduce positive evidence to rebut this presumption. A letter confirming telephone discussions months after judgment, without evidence of diligent follow-up with the court registry, is insufficient to rebut the presumption. 2. Where an applicant fails to rebut the Rule 63(3) presumption and files a rescission application outside the 30-day period stipulated in Rule 63(1), the applicant must first seek condonation for late filing. An application filed without such condonation is improperly before the court. 3. Rule 63(1) requires that an application for rescission be filed within 30 days of knowledge of the judgment, not that it be set down and heard within that period. Delays in set down beyond the applicant's control should not result in penalty. 4. A party cannot escape the consequences of its legal practitioner's lack of diligence in pursuing court matters.
