The binding legal principles established are: (1) An interdict cannot be granted against conduct that is prima facie lawful, including the execution of a valid writ of execution issued by the Registrar of the High Court; (2) For an affidavit to be validly commissioned, the deponent and the commissioner of oaths must be in the same geographical location for the signing and commissioning to occur contemporaneously - an affidavit signed in one location and commissioned in another is defective; (3) An applicant seeking an interdict must establish: (a) a clear right, (b) irreparable harm actually committed or reasonably apprehended, and (c) the absence of an alternative remedy that is adequate in the circumstances; (4) Rule 63 of the High Court Rules SI 202/2021 provides an interpleader remedy for third parties claiming ownership of property subject to execution, and where such remedy is available, an interdict application is inappropriate; (5) An application is frivolous and vexatious, warranting punitive costs on a legal practitioner and client scale, where defects are pointed out but not rectified and the applicant fails to appear at the hearing, demonstrating lack of seriousness and an apparent intention to delay proceedings.
