In 1975, senior NUSAS leaders were arrested under s6 of the
Terrorism Act and charged under the Suppression of Communism and Unlawful Organisations Acts. The five accused were Glenn Moss, Charles Nupen, Eddie Webster (a lecturer at
Wits University), Cedric de Beer and Karel Tip. The charges related to a series of political campaigns run by NUSAS, including the 1974 campaign to release all political prisoners, a campaign on the history of opposition politics, the Wages Commissions, as well as support for
Black Consciousness and the
Freedom Charter. The state alleged that the five accused had entered into a conspiracy to further the objectives of communism and aims of the African National Congress and
South African Communist Party. It was unclear why he was called so the defence team, led by
Arthur Chaskalson, applied for permission to consult with three ANC leaders serving sentences on
Robben Island,
Nelson Mandela,
Walter Sisulu, and
Govan Mbeki.
George Bizos, also on the defence team, met with the prisoners and learned not only that they knew about the trial but were willing to testify for the defence to rebut Hlapane's evidence. In the event, the defence team decided not to call the political prisoners to testify because it would raise the profile of the trial and risk the magistrate becoming hostile towards the accused. In a verdict delivered over two days in December 1976 the five accused were found not guilty on the basis that the state had failed to establish a conspiracy. ==Notable alumni==
