I want to know the answer to the following question:
When did South Africa refuse to surrender Namibia?
All the background I'm provided with is that "Following the League's replacement by the United Nations in 1946, South Africa refused to surrender its earlier mandate to be replaced by a United Nations Trusteeship agreement, requiring closer international monitoring of the territory's administration (along with a definite independence schedule).". Is that enough to answer the question?
Answer: yes
