During a severe storm in the Port of Durban on 10 October 2017, the merchant vessel MV ‘MSC Susanna’ broke free from her moorings and drifted, colliding with several vessels and port infrastructure. One of the vessels damaged was the FNS ‘Floreal’, a French naval ship under the control of the Ministère des Armées of the French Republic. Damage was also caused to port infrastructure owned by Transnet (SOC) Ltd, acting through the National Ports Authority. Transnet instituted a claim of approximately R23 million against the owners, underwriters, and demise charterers of the MSC Susanna. The French Ministry counterclaimed for damages of nearly €10 million in respect of damage to the Floreal. Given the magnitude of the claims, the appellants instituted limitation proceedings under s 261(1)(b) of the Merchant Shipping Act 57 of 1951 (MSA) and sought to join the French Ministry to the limitation action. The Ministry opposed the joinder, contending that s 3(6) of the MSA excluded the application of the Act in respect of ships belonging to foreign defence forces. The High Court upheld this objection, prompting the appeal to the Supreme Court of Appeal.
