Its divided this bibliography on parliamentary oversight into seven sections, in a structure that attempts to include the most relevant aspects of Parliament’s powers of scrutiny. Section 1 approaches a General Theory of parliamentary oversight (powers of scrutiny in general, definition under the Constitution, political basis, comparative analysis and historical perspective). Section 2 looks into the granting and removal of Parliament’s confidence. Section 3 analyses the typical instruments applied in the context of rationalised Parliamentarianism in the second half of the 20 Century (questions and interpellations). There is a fourth section devoted to an analysis of published works regarding inquiry committees, an extremely relevant and interesting instrument of parliamentary oversight today. The following section deals with hearings and requests for information and documents. Section 6 focuses on an analysis of the specificities of powers of scrutiny when dealing with sensitive material such as official secrets, secret funds or foreign and defence policy. Finally, in Section 7 we have looked into the particular features of parliamentary scrutiny in the Autonomous Regions. REPERTORIO BIBLIOGRAFICO SOBRE CONTROL PARLAMENTARIO 439
