Vryburg District, [Northern Cape, now North West Province]. At the time, Sobukwe was living in Mafolo Bantu Township, Johannesburg, Transvaal [now Gauteng]. The documentation on the banishment noted that Sobukwe and Leballo had both been arrested and were awaiting trial“but it [was] necessary to have a banishment order in hand just in case they are released.” Sobukwe never spent time in banishment as he was sentenced to imprisonment for incitement. On 4 May 1960 Sobukwe was sentenced to three years in prison for inciting Africans to demand the repeal of the pass laws. He refused to appeal against the sentence, as well as the aid of an attorney, on the grounds that the court had no jurisdiction over him as it could not be considered either a court of law or a court of justice. At the end of his three-year sentence on 3 May 1963, Parliament enacted a General Law Amendment Act. The Act included what was termed the 'Sobukwe Clause', which empowered the Minister of Justice to prolong the detention of any political prisoner indefinitely. Subsequently, Sobukwe was moved to Robben Island, where he remained for an additional six years. The Clause was never used to detain anyone else. The Sobukwe Clause was renewed every year – when it was due to expire on 30 June 1965, the government renewed it. While on Robben Island, Sobukwe was kept in solitary confinement – his living quarters were separate from the main prison and he had no contact with any other prisoners. He was, however, allowed access to books and civilian clothes. As a result, Sobukwe spent much of his time studying, and he obtained a degree in Economics from the University of London. In 1964 Sobukwe was offered a job by the National Association for the Advancement of Coloured People and the Montgomery Fellowship for Foreign Aid in the US. He applied to leave the country with his family to take up the employment but was denied permission by the Minister of Justice, John Vorster. Sobukwe was released from prison in May 1969 and was banished to Galeshewe in Kimberley, where he was joined by his family. However, he remained under twelve-hour house arrest and his banning order prohibited him from participating in any political activity. In 1970 Sobukwe successfully applied for a teaching post at the University of Wisconsin in the US, but the Apartheid government refused his request
