1. An application for substitution of a party after judgment is permissible under common law where it involves mere correction of a wrong name without changing the identity of the party to the judgment, as distinguished from a material amendment. 2. A patent error under Rule 29(1)(b) is an error attributable to the court itself where the judgment or order does not reflect the true intention of the judicial officer, and includes situations where a party is cited that was never involved in the proceedings. 3. Where a court order contains a patent error that is common cause and the application for correction has good prospects of success, condonation may be granted despite inordinate delay and an unacceptable explanation, where the interests of justice require it and refusing correction would render proceedings nugatory. 4. A party cannot approbate and reprobate by taking inconsistent positions - having corrected its own citation in proceedings, it cannot later claim to be a different entity. 5. A party making a positive assertion, whether applicant or respondent, bears the onus of proving that assertion.
