The territory of South West Africa was one of the German possessions from which Germany renounced by art 119 Treaty of Versailles. The territory was placed under a Mandate by the League of Nations conferred upon the Union of South Africa.
GA asked the opinion. What is the international status of the Territory of South-West Africa
‘The mandate was created in the interest of the inhabitants of the territory and of the humanity in general, as an international institution with and international object – a sacred trust of civilisation. It is therefore not possible to draw any conclusion by analogy from the notion of mandate in national law or any other conception of that law’
