7.2 Legislative & Judicial Branches: Check and Balance Mechanisms

The Philippine system of government is structured upon the foundational doctrine of Separation of Powers, balanced by an intricate network of Checks and Balances. Under the 1987 Constitution, legislative power is vested in the Congress of the Philippines (Article VI), executive power in the President (Article VII), and judicial power in the Supreme Court and lower courts (Article VIII). No single branch is supreme; each operates within its constitutional sphere while checking potential excesses of the others.

Legislative Structure & Constitutional Mandate

Congress is a bicameral body consisting of:

1. The Senate: Composed of twenty-four (24) Senators elected at large by qualified voters. Senators serve a six-year term, with terms staggered so that twelve Senators are elected every three years. No Senator may serve for more than two (2) consecutive terms.
2. The House of Representatives: Composed of not more than two hundred fifty (250) members (unless fixed by law), consisting of District Representatives elected from legislative districts and Party-List Representatives elected through a national party-list system constituting 20% of the total membership. Representatives serve a three-year term and are limited to three (3) consecutive terms.

Legislative Oversight & Check Powers

Congress exercises powerful oversight mechanisms over the executive branch to maintain accountability and protect public funds.

1. The Power of the Purse

Section 24 of Article VI mandates that all appropriations, revenue, or tariff bills shall originate exclusively in the House of Representatives, though the Senate may propose or concur with amendments. Section 29 explicitly mandates: "No money shall be paid out of the Treasury except in pursuance of an appropriation made by law."

Through the annual General Appropriations Act (GAA), Congress defines agency budgets, allocations, and spending conditions. In landmark rulings (Belgica v. Ochoa, G.R. No. 208566; Araullo v. Aquino, G.R. No. 209287), the Supreme Court invalidated post-enactment legislator participation in budget execution (the "Pork Barrel" system) and executive impoundments that violated legislative appropriation boundaries, reinforcing the exclusivity of legislative control over public funds.

Presidential Veto & Legislative Override Mechanics

When a bill passes both the Senate and the House of Representatives, it is presented to the President for approval (Article VI, Section 27).

Veto Override

If the President vetoes a bill, it is returned with objections to the House of Origin. Congress may override the presidential veto by a two-thirds (2/3) vote of all the Members of EACH House (Senate and House of Representatives voting separately). Upon achieving this threshold, the bill automatically becomes law without presidential signature.

Item Veto vs. Pocket Veto

• Item Veto (Line-Item Veto): The President has the power to veto particular items in an appropriation, revenue, or tariff bill, while approving the remaining sections. If the President vetoes an item in an ordinary non-revenue bill, the entire bill is deemed vetoed.
• Inaction: If the President does not sign or veto a bill within thirty (30) days after receipt, the bill automatically becomes law as if signed. The Philippine system does not recognize a "pocket veto."

Judicial Power & Expanded Judicial Review

Judicial power is vested in one Supreme Court composed of a Chief Justice and fourteen (14) Associate Justices, and in lower courts created by law (such as the Court of Appeals, Sandiganbayan, Court of Tax Appeals, Regional Trial Courts, and Metropolitan Trial Courts).

Expanded Judicial Review (Article VIII, Section 1)

Section 1 defines judicial power in two parts:

1. Traditional Scope: The duty of the courts of justice to settle actual controversies involving rights which are legally demandable and enforceable.
2. Expanded Scope: The power 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 expanded judicial review clause allows citizens to challenge unconstitutional executive orders, legislative acts, or administrative rules even in matters traditionally treated as political questions, provided grave abuse of discretion is established (Tañada v. Angara, G.R. No. 118295).

Judicial Independence Safeguards

To protect the judiciary from political pressure and preserve constitutional objectivity, Article VIII incorporates stringent structural safeguards:

1. Fiscal Autonomy (Section 3): Appropriations for the Judiciary cannot be reduced by Congress below the amount appropriated for the previous year and must be automatically and regularly released.
2. The Judicial and Bar Council (JBC - Section 8): Members of the Supreme Court and lower courts are appointed by the President from a list of at least three nominees prepared by the JBC for every vacancy. These appointments do not require confirmation by the Commission on Appointments.
3. Exclusive Rule-Making Power (Section 5, Para. 5): The Supreme Court has the exclusive power to promulgate rules concerning the protection and enforcement of constitutional rights, pleading, practice, and procedure in all courts, and admission to the practice of law (Echegaray v. Secretary of Justice, G.R. No. 132601). Congress cannot pass laws that repeal or modify procedural rules of court.
