I. Introduction
The Doctrine of Judicial Review is the fundamental power vested in the Philippine judiciary, particularly the Supreme Court, to examine and invalidate acts of the legislative and executive branches of government that contravene the Constitution. It is the cornerstone of constitutional supremacy, ensuring that all governmental exercise of power remains within the boundaries set by the fundamental law. This power transforms the Constitution from a mere symbolic document into an enforceable and paramount legal standard.
II. Constitutional Basis
The power is explicitly granted under Article VIII, Section 1 of the 1987 Constitution, which states that “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.” This provision expands the traditional notion of judicial review, embedding it as a duty, not merely a power.
III. Historical Context and Jurisprudential Foundation
While the 1987 Constitution provides its current textual basis, the doctrine’s operative principles were firmly established in the seminal case of Angara v. Electoral Commission (1936). The Supreme Court, drawing from American jurisprudence, declared that “the Constitution is a definition of the powers of government,” and it is “the role of the judiciary to declare what the law is.” This established the Court as the ultimate interpreter of the Constitution.
IV. Scope and Limitations
Judicial review is not an unlimited power. It is circumscribed by essential requisites: (1) there must be an actual case or controversy involving legally demandable rights; (2) the question of constitutionality must be raised by a proper party with legal standing (i.e., one who has sustained or is in imminent danger of sustaining a direct injury); (3) the constitutional question must be raised at the earliest opportunity; and (4) the resolution of the constitutional issue must be necessary for the determination of the case itself (the “lis mota” doctrine). The Court will not rule on hypothetical questions or issue advisory opinions.
V. The “Grave Abuse of Discretion” Standard
A pivotal innovation of the 1987 Constitution is the express grant of the power to review acts for “grave abuse of discretion amounting to lack or excess of jurisdiction.” This standard, under Article VIII, Section 1, is broader than the traditional “capricious and whimsical” test. It allows the Supreme Court to strike down not only acts without jurisdiction but also those exercised in an arbitrary, despotic, or patently violative of the law manner, even if performed within jurisdictional bounds. This fortified the Court’s role as a check on political branches.
VI. Hierarchy of Courts and Finality
The power of judicial review is shared by all courts, but with a hierarchy of authority. Lower courts may pass upon the constitutionality of statutes, but their decisions are subject to appeal. The Supreme Court, as the court of last resort, has the final say. Under Article VIII, Section 4(2), the Supreme Court’s decisions on the constitutionality of any treaty, international or executive agreement, or law are reviewable only by the Court itself and become effective immediately upon publication. This finality underscores its role as the constitutional arbiter.
VII. Effects of a Declaration of Unconstitutionality
When a law or act is declared unconstitutional, it is considered void ab initio (from the beginning). It produces no legal effects, as if it had never been enacted. The doctrine of operative fact, however, may be applied as an exception to mitigate inequity, recognizing that prior to the declaration of nullity, the law was acted upon in good faith, and the effects of such actions may be respected.
VIII. Key Jurisprudential Applications
The doctrine has been applied across the spectrum of governance: to invalidate laws infringing on civil liberties (Ople v. Torres, on the National ID System); to check executive overreach (David v. Arroyo, on presidential issuances); to define the limits of legislative power (Philippine Judges Association v. Prado, on postal privileges); and to delineate the co-equal branches’ boundaries (Cruz v. Secretary of Environment and Natural Resources, on executive power). Each application reaffirms the Constitution’s supremacy.
IX. Practical Remedies
A party seeking to invoke judicial review must initiate the appropriate legal proceeding, typically a petition for certiorari, prohibition, or mandamus under Rule 65 of the Rules of Court for grave abuse of discretion, or a declaratory relief action under Rule 63 for questions of statutory constitutionality prior to enforcement. In constitutional litigation, counsel must meticulously plead and establish the existence of an actual case, the client’s standing, and the direct injury caused by the alleged unconstitutional act. Exhaustion of administrative remedies may be required, except when the issue is purely legal, the act is patently unconstitutional, or urgency dictates immediate judicial intervention. Strategic consideration should be given to filing directly with the Supreme Court under its original jurisdiction when the matter is of transcendental importance, requiring a definitive and expedited ruling to guide public conduct and government policy.
