Humane and successful diplomatic efforts by Wachuku to save Mandela and others from death penalty at the Rivonia Trial were given more light by University of North Carolina at Chapel Hill Henry Brandis Professor of Law Emeritus: Kenneth S. Broun, in his published book: "Saving Nelson Mandela: The Rivonia Trial and the Fate of South Africa ". Professor Broun points out that Sir Hugh Stephenson: United Kingdom's Ambassador to South Africa met with Foreign Minister Hilgard Muller of South Africa with regard to "the Wachuku request" that Mandela and others must not be sentenced to death. When Stephenson mentioned Wachuku's stand to Muller, Muller responded by saying that Wachuku's position was "very interesting." Muller went on to say that the South African government had utmost respect for Wachuku and that at the United Nations General Assembly, Wachuku had made a oneness-of-humankind, "helpful speech" wherein Wachuku stated that "white people were also Africans." Afterwards, Stephenson reported to the British government and Wachuku that his impression was that "death sentences would not be carried out" on Nelson Mandela and others based on the request by Wachuku.
