Lead HV (Pty) Ltd and Another v HV Test (Pty) Ltd

Lead HV (Pty) Ltd (first appellant) and HV Test (Pty) Ltd (respondent) are suppliers of goods and services in the medium, high and extra high voltage electrical engineering field and are in direct competition. Mr Lombaard (second appellant) is the general manager of the first appellant. During 2020, two of the respondent's former employees, Ms Sheik and Mr Ledwaba, who were subject to restraint of trade agreements with the respondent, obtained employment with the first appellant. An Anton Piller interdict was obtained against Sheik, Ledwaba and the appellants on 10 September 2020 and confidential information belonging to the respondent was found in possession of Sheik and Ledwaba. The respondent alleged that they provided the appellants with this information in breach of their restraint of trade agreements and that the information was used to advance the business of the appellants to the detriment of the respondent. The respondent launched an urgent application seeking an interdict to prevent them from dealing with its confidential information, approaching its clients and/or disclosing the identities of any party with whom the confidential information may have been shared. Only the appellants opposed the urgent application. An order was granted by default against Sheik and Ledwaba on 13 November 2020. The application against the appellants was struck from the urgent roll for want of urgency but proceeded in the ordinary course and was heard on 14 April 2021. On 12 August 2021, a final interdict was granted restraining the appellants from utilizing the confidential information of the respondent.

• Whether the high court misdirected itself on the facts or law in granting the final interdict
• Whether there existed a live controversy between the parties at the time of the appeal

The appeal was dismissed.

Courts will not adjudicate an appeal if it no longer presents an existing or live controversy. Where the harm complained of has been addressed and sufficient time has elapsed such that the rights sought to be protected have become academic, the appeal will be dismissed as moot. An appellate court will not interfere with a high court's grant of a final interdict where the high court did not misdirect itself on the facts or the law.

The Court observed that it was unclear why leave to appeal was granted to this Court in the first instance. The Court commented that "the proverbial horse has bolted" in relation to the practical effect of the interdict and any potential harm, indicating that by the time of the appeal (2024) the events of 2020 and the order of August 2021 had been overtaken by time. The Court noted that courts exist to determine live disputes, emphasizing the fundamental purpose of judicial intervention.

This case reinforces the principle that South African courts will not adjudicate appeals where there is no longer a live controversy between the parties. It affirms that courts exist to determine live disputes and will not engage in academic exercises. The case also confirms the approach to appeals against interdicts in restraint of trade and confidential information cases, particularly that appellate courts will not interfere with factual findings of the high court absent misdirection on facts or law. It demonstrates the practical application of the mootness doctrine in South African appellate law.
