I. Introduction

This memorandum exhaustively examines the constitutional doctrine commonly referred to as the “power of the purse” within the Philippine legal system. This power, a cornerstone of the system of checks and balances, primarily resides in the Congress of the Philippines through its authority over appropriation bills and revenue bills. The analysis will delineate the scope, limitations, and procedural intricacies governing this legislative power, its interaction with executive authority, and its role in ensuring fiscal accountability and the separation of powers.

II. Constitutional Foundations

The power of the purse is enshrined in Article VI, Section 24, and Article VII, Section 22 of the 1987 Constitution. The core provisions are:
Article VI, Section 24: “All appropriation, revenue or tariff bills, bills authorizing increase of the public debt, bills of local application, and private bills shall originate exclusively in the House of Representatives, but the Senate* may propose or concur with amendments.”
Article VI, Section 25: This section provides detailed rules on appropriation bills, including the general appropriations bill, the prohibition against riders, the requirement for a specified purpose, and the inappropriability* of certain funds.
Article VI, Section 28: This section outlines the rule on taxation, stating that “the rule of taxation shall be uniform and equitable” and that “The Congress shall evolve a progressive system of taxation*.”
Article VII, Section 22: “The President shall submit to the Congress within thirty days from the opening of every regular session, as the basis of the general appropriations bill, a budget of expenditures and sources of financing, including receipts from existing and proposed revenue measures*.”

III. Definition and Classification of Key Bills

Appropriation Bill: A legislative act that authorizes the withdrawal of funds from the National Treasury for a specified purpose. The most critical is the General Appropriations Act (GAA)*, which allocates funds for the operation of the entire government for a fiscal year.
Revenue Bill*: A legislative act that levies taxes, tariffs, duties, or other impositions to raise government funds. This includes laws that amend, revise, or repeal existing tax statutes.
Tariff Bill: A specific type of revenue bill* that deals with duties on imports and exports.
Bill Authorizing Increase of the Public Debt*: A legislative act that permits the government to incur new debt obligations.

IV. The Origination Clause: Article VI, Section 24

This clause establishes a constitutional qualification on the legislative process for fiscal matters. The House of Representatives holds the exclusive power to initiate (i.e., file the first formal legislative document) the bills enumerated. However, the Senate is not relegated to a passive role. The clause explicitly grants the Senate the co-equal power to “propose or concur with amendments.” Jurisprudence clarifies that this includes the power to propose amendments in the nature of substitutes, effectively allowing the Senate to overhaul the House version entirely, provided the amended bill remains within the subject matter of the originated bill. The clause is a recognition of the House’s closer proximity to the people in matters of taxation and spending.

V. Specific Rules on Appropriation Bills (Article VI, Section 25)

This section imposes strict limitations to prevent fiscal abuse:
Purpose Specification: No money shall be paid out of the National Treasury except in pursuance of an appropriation made by law and for a specified purpose*.
Prohibition on Riders: The general appropriations bill shall not contain any provision or rider that does not relate specifically to appropriation*. This prevents the insertion of substantive legislation into the must-pass budget bill.
Discretionary Fund: A discretionary fund appropriated for particular officials shall be disbursed only for public purposes* and supported by appropriate vouchers and subject to audit guidelines.
Prohibition on Transfer of Appropriations: No law shall be passed authorizing any transfer of appropriations. However, the President, Senate President, House Speaker, Chief Justice, and heads of Constitutional Commissions may, by law, be authorized to augment* any item in the GAA from savings within their respective offices.
Re-enacted Budget: If Congress fails to pass the GAA before the fiscal year begins, the previous year’s GAA is deemed re-enacted*, but only for ongoing programs and projects.

VI. Specific Rules on Revenue/Tax Bills (Article VI, Section 28)

Uniformity and Equity Rule: The rule of taxation must be uniform and equitable. Congress shall evolve a progressive system of taxation*.
Charitable Institutions*: Charitable institutions, churches, mosques, and non-profit cemeteries are exempt from real property tax.
Tax Exemptions: No tax exemption shall be granted without the concurrence of a majority of all members of Congress*.
Delegation to Local Governments: Congress may, by law, authorize local government units to exercise the power of taxation*.

VII. Comparative Analysis: Appropriation vs. Revenue Bills

The following table compares the key constitutional attributes of appropriation bills and revenue bills.

VIII. The Executive’s Role: Submission and Veto Powers

The power of the purse is shared, though asymmetrically, with the executive branch.
Budget Submission: The President has the constitutional duty to prepare and submit a budget of expenditures and sources of financing* to Congress. This serves as the executive’s blueprint and the starting point for congressional deliberation, but Congress is not bound by its specifics.
Veto Power: The President’s primary check on the legislative power of the purse is the veto power* under Article VI, Section 27.
For appropriation bills: The President exercises the item veto or line-item veto power. The President may veto particular appropriation items while approving others. An item refers to a specific and separable appropriation*.
For revenue bills: The President may only veto the bill in its entirety; the line-item veto* does not apply.
Veto Override: Congress may override a presidential veto by a two-thirds vote* of all its members, voting separately. This reaffirms the ultimate legislative supremacy in fiscal matters.

IX. Judicial Review and Limitations

While the power of the purse is a legislative prerogative, it is not absolute and is subject to judicial review.
Constitutional Limitations: All appropriation and revenue bills* must comply with substantive constitutional limits (e.g., no public funds for religious purposes under Article VI, Section 29(2); uniformity in taxation).
Procedural Compliance: Courts can invalidate laws for non-compliance with the origination clause or other mandatory procedures (e.g., the presence of an unconstitutional rider* in the GAA).
Non-Encroachment: The judiciary cannot dictate to Congress how to appropriate funds or set tax rates, as these are political questions* inherently within legislative discretion, provided constitutional boundaries are observed.

X. Conclusion

The power of the purse is a fundamental legislative power designed to ensure popular control over public finances. Its division between the House of Representatives (origination) and the Senate (amendment), its specific constitutional constraints (e.g., no riders, specification of purpose), and its interplay with the executive’s budget submission and veto powers create a complex but deliberate system of checks and balances. This framework aims to prevent fiscal tyranny, promote transparency, and ensure that the government’s taxing and spending powers are exercised responsibly and in accordance with the Constitution. Ultimate authority rests with Congress, but its exercise is carefully channeled by detailed constitutional rules subject to the oversight of both the executive and judicial branches.
