This work examines the legal effects of a declaration of a state of emergency under the Public Safety Act 3 of 1953 and the exercise of legislative and administrative powers pursuant thereto. The general basis of judicial control over executive action and the various devices used to limit or oust the court's jurisdiction are set out and explained. Against this background, the courts' performance of their supervisory role under the special circumstances of emergency rule is critically surveyed and assessed. The legal issues raised by the exercise of emergency powers is examined at the various levels of their deployment: first, the declaration of a state of emergency; second, the making of emergency regulations; third, their execution by means of administrative action, including detention, banning, censorship and the use of force. The major cases concerning emergency issues, both reported and unreported, are analysed in their appropriate contexts, and an overview provided of the effects of emergency regulations and orders on such freedoms as South Africans enjoy under the 'ordinary' law. Finally, an attempt is made to assess how these decisions have affected the prospect of judicial review of executive action, both in the emergency context and in the field of administrative law generally. The conclusion is that, however far the Appellate Division may appear to have gone towards eliminating the role of the law in the emergency regime, grounds remain for the courts to exercise a more vigorous supervisory role should they choose to do so in future.

Text in Afrikaans / The broad focus of the thesis is an analysis of the meaning and the modern development of the doctrine of the separation of power (trias politica) and the application thereof in the constitutional development in South Africa. The first chapter outlines the historical restrictions that were placed on governmental authority by the trias politica doctrine. In the following chapter the application of the trias politica doctrine in different governmental systems (parliamentary, presidential and semipresidential) are analysed. In the third chapter an analysis is made of the constitutions of the former Boer republics, chronologically followed by an analysis of the 1909, 1961 and 1983 Constitutions, to establish to which extent the trias politica doctrine was incorporated in the respective constitutions. In the subsequent chapters, the focus shifts to the constitutions in the post democratic era, namely the 1993 interim Constitution and the 1996 (final) Constitution. It is evident that the new supreme Constitution and an independent judiciary yielded to a stronger adherence to the separation of power principle. It is also evident that the retainment of the parliamentary system, with a fused legislature and executive authority, inhibited a stronger separation of power. The inclusion of sosioeconomic rights in the Constitution resulted in a more direct involvement in governmental policy. However, the Constitutional Court managed to maintain a fine balance between reviewing policy and the formulation of policy. In the closing chapter a short summary is provided, followed by comments on possible alternatives to the existing system to ensure a stronger separation of powers. / Public, Constitutional and International Law / LL.
