Give examples of cases in which the Court exercised the power of judicial review over congressional actions.

There is indeed a plethora of cases in which this Court exercised the power of judicial review over congressional action. 

Thus, in Santiago v. Guingona, Jr.,⁶⁰ this Court ruled that it is well within the power and jurisdiction of the Court to inquire whether the Senate or its officials committed a violation of the Constitution or grave abuse of discretion in the exercise of their functions and prerogatives.

 In Tanada v. Angara,⁶¹ in seeking to nullify an act of the Philippine Senate on the ground that it contravened the Constitution, it held that the petition raises a justiciable controversy and that when an action of the legislative branch is seriously alleged to have infringed the Constitution, it becomes not only the right but in fact the duty of the judiciary to settle the dispute. 

 In Bondoc v. Pineda,⁶² this Court declared null and void a resolution of the House of Representatives withdrawing the nomination, and rescinding the election, of a congressman as a member of the House Electoral Tribunal for being violative of Section 17, Article VI of the Constitution. 

 In Coseteng v. Mitra,⁶³ it held that the resolution of whether the House representation in the Commission on Appointments was based on proportional representation of the political parties as provided in Section 18, Article VI of the Constitution is subject to judicial review.

 In Daza v. Singson,⁶⁴ it held that the act of the House of Representatives in removing the petitioner from the Commission on Appointments is subject to judicial review. 

In Tanada v. Cuenco,⁶⁵ it held that although under the Constitution, the legislative power is vested exclusively in Congress, this does not detract from the power of the courts to pass upon the constitutionality of acts of Congress. 

In Angara v. Electoral Commission,⁶⁶ it ruled that confirmation by the National Assembly of the election of any member, irrespective of whether his election is contested, is not essential before such member-elect may discharge the duties and enjoy the privileges of a member of the National Assembly.
