I want to know the answer to the following question:
Which council submitted petitions for Namibia's independence?
All the background I'm provided with is that "In 1966 the International Court of Justice dismissed a complaint brought by Ethiopia and Liberia against South Africa's continued presence in the territory, but the U.N. General Assembly subsequently revoked South Africa's mandate, while in 1971 the International Court of Justice issued an "advisory opinion" declaring South Africa's continued administration to be illegal.". Is that enough to answer the question?
