More than 50 top officials and senior members of SWAPO – amounting to almost the entire leadership of the liberation movement inside Namibia – were arrested and detained in a countrywide police purge at the end of April, while others were forced into hiding. The arrests, which immediately preceded the announcement that a South African-sponsored and tribally-based National Assembly was to be established in the territory, were ordered by the SWAPO Administrator General Justice Steyn under Proclamation AG26. The emergency regulations contained in AG26, which was promulgated on 18 April 1979, vest unqualified powers in Justice Steyn to detain any person (s) whose actions are felt likely to "promote violence or intimidation", indefinitely without charge or trial. Persons held under AG26 have no recourse to any court of law and will only be told the reasons for their arrest at the discretion of the Administrator General.
Many of those arrested have been detained and interrogated on numerous previous occasions. A number – notably SWAPO's Administrative Secretary Axel Johannes – have been tortured and imprisoned for considerable periods of time. Then case histories clearly illustrate the cat-and-mouse game that the South African government has always played with SWAPO. Each crackdown on the organization has been timed to coincide with some fresh development in South Africa's long-standing strategy of consolidating its hold on Namibia, while appearing to be cooperating with international negotiations over the territory's future. Prior to these latest detentions, numerous arrests took place on the eve of the elections organised by South Africa in defiance of the UN in December 1978.
There has been widespread speculation that the South African government will now ban SWAPO, using the supposedly independent National Assembly established in the territory as a front for such a move. Hints to this effect have been given by the SA Prime Minister Mr. P.W. Botha, who said in Cape Town a few days before the detentions that if SWAPO continued to boycott the "democratic process" inside Namibia then it must bear the consequences. On 30 April the SWAPO Administrator General stated that he "had no intention" of banning SWAPO "at this stage", but merely wished to "make it change its ways". The detention of the SWAPO leadership, he said, was intended firstly, to disrupt the liberation movement's organizational machinery; secondly, to show Namibians that the authorities were looking after their interests; and thirdly, to demonstrate that the SA government had not been "unnerved" by SWAPO's armed guerilla struggle.
