El Senado en la jurisprudencia del Tribunal Constitucional

This paper analyses the cases of the Constitutional Court related to the Senate in its last twenty five years of activity. The first conclusion is that there are not many cases related to the Senate, but those analysed are enough representative of the main task given to the Senate by the Constitution. Mainly: senators status, internal organisation, functions and powers. There is a parallelism between the jurisprudence of that related to the Senate and that to the Congress and to the Parliaments of the Autonomy Regions (Comunidades Autonomas), although there are some cases only referred to the Senate, especially the cases referred to the Senate’s powers, as far as both Chambers have different powers. The paper also focuses on the Constitutional Process Law applicable to the questions referred.
