South Africa‘s President Zuma has contributed significantly to the growth and development of the country‘s constitutional jurisprudence. Since taking office in 2009, there have been numerous constitutional cases decided by various courts against him both personally and as a president. Three recent judgments are particularly worth noting since they have changed the way we understand the Constitution (of the Republic of South Africa, 1996). These cases relate to the separation of powers with regards to the appointment of the National Director of Public Prosecutions, the impeachment of the president, and the appointment of a judge to head a judicial commission of enquiry. The paper, therefore, will discuss and analyze these cases and their implication on the existing constitutional jurisprudence on separation of powers in relation to the powers of the president and parliament, the independence of the judiciary and the National Director of Prosecution.
