This chapter recounts the history of constitutional developments in Angola leading up to the 2010 constitution. It introduces the new Angolan Constitutional Court and discusses the first and thus far only substantive decision of this Court—the Parliamentary Oversight Judgment of 9 October 2013—a serious constitutional conflict between parliament and the president. The Court held that the 2010 constitution had reduced the powers of parliament as compared to the previous text and that parliament lacked the power to question the executive or to summon ministers to hearings before it. Since these are presidential powers, the Court held, parliament may not arrogate them, though it may request the president to supply information or order his ministers before it. Although the conservative leaning of the Court in this dispute disappointed the opposition and many commentators, the judgment strengthened the rule of law and of the constitutional state.
