The via media technique of characterisation in private international law, as proposed by the Canadian author Falconbridge, was – over a period of three decades – gradually adopted by the courts in Lesotho, South Africa, Zimbabwe, and, more recently, Eswatini. In a particular dispute, which is used as angle of incidence for the discussion below, the High Court of Swaziland (now Eswatini) applied the rules of the lex fori pertaining to liberative prescription (the limitation of actions) against the background of the via media technique. The decision was overruled by the Supreme Court of Eswatini, which – using the same technique – applied the proper law of the contract in this regard. In this contribution, the Canadian doctrine and its application by the Eswatini and other Southern African courts is critically discussed. The scenario in the Eswatini cases provides an example of what the author calls the phenomenon of dual cumulation. He attempts to provide guidance for the development of Southern African private international law in this regard beyond the via media technique.

加拿大作家法尔康布里奇 (Falconbridge) 提出的通过媒体表征国际私法的技术——在过去的三十年里——逐渐被莱索托、南非、津巴布韦以及最近的埃斯瓦蒂尼的法院采用。在用作下文讨论的入射角的特定争议中，斯威士兰高等法院（现为斯威士兰）在通过媒体的背景下适用了有关解放时效（诉讼时效）的法院地法规则技术。该决定被埃斯瓦蒂尼最高法院驳回，后者使用相同的技术在这方面适用了合同的适当法律。在这份文稿中，批判性地讨论了加拿大学说及其在 Eswatini 和其他南部非洲法院的应用。埃斯瓦蒂尼案中的情景提供了作者所说的双重累积现象的一个例子。他试图通过媒体技术为南部非洲国际私法的发展提供指导。
