A proposed bill is not subject to judicial review because it is not a law. A proposed bill creates no right and imposes no duty legally enforceable by the Court. A proposed bill, having no legal effect, violates no constitutional right or duty. The Court has no power to declare a proposed bill constitutional or unconstitutional because that would be in the nature of rendering an advisory opinion on a proposed act of Congress. The power of judicial review cannot be exercised in vacuo. - Montesclaros vs Comelec : 152295 : July 9, 2002 : J. Carpio : En Banc

The Courts power of judicial review may be exercised in constitutional cases only if all the following requisites are complied with, namely: (1) the existence of an actual and appropriate case or controversy; (2) a personal and substantial interest of the party raising the constitutional question; (3) the exercise of judicial review is pleaded at the earliest opportunity; and (4) the constitutional question is the lis mota of the case.[21]

In the instant case, there is no actual controversy requiring the exercise of the power of judicial review. While seeking to prevent a postponement of the May 6, 2002 SK elections, petitioners are nevertheless amenable to a resetting of the SK elections to any date not later than July 15, 2002. RA No. 9164 has reset the SK elections to July 15, 2002, a date acceptable to petitioners. With respect to the date of the SK elections, there is therefore no actual controversy requiring judicial intervention.

Petitioners prayer to prevent Congress from enacting into law a proposed bill lowering the membership age in the SK does not present an actual justiciable controversy. A proposed bill is not subject to judicial review because it is not a law. A proposed bill creates no right and imposes no duty legally enforceable by the Court. A proposed bill, having no legal effect, violates no constitutional right or duty. The Court has no power to declare a proposed bill constitutional or unconstitutional because that would be in the nature of rendering an advisory opinion on a proposed act of Congress. The power of judicial review cannot be exercised in vacuo.[22] The second paragraph of Section 1, Article VIII of the Constitution states

Judicial power includes the duty of the courts of justice to settle actual controversies involving rights which are legally demandable and enforceable, and to determine whether or not there has been a grave abuse of discretion amounting to lack or excess of jurisdiction on the part of any branch or instrumentality of the Government. (Emphasis supplied)

Thus, there can be no justiciable controversy involving the constitutionality of a proposed bill. The Court can exercise its power of judicial review only after a law is enacted, not before.

Under the separation of powers, the Court cannot restrain Congress from passing any law, or from setting into motion the legislative mill according to its internal rules. Thus, the following acts of Congress in the exercise of its legislative powers are not subject to judicial restraint: the filing of bills by members of Congress, the approval of bills by each chamber of Congress, the reconciliation by the Bicameral Committee of approved bills, and the eventual approval into law of the reconciled bills by each chamber of Congress. Absent a clear violation of specific constitutional limitations or of constitutional rights of private parties, the Court cannot exercise its power of judicial review over the internal processes or procedures of Congress.[23]

The Court has also no power to dictate to Congress the object or subject of bills that Congress should enact into law. The judicial power to review the constitutionality of laws does not include the power to prescribe to Congress what laws to enact. The Court has no power to compel Congress by mandamus to enact a law allowing petitioners, regardless of their age, to vote and be voted for in the July 15, 2002 SK elections. To do so would destroy the delicate system of checks and balances finely crafted by the Constitution for the three co-equal, coordinate and independent branches of government.
