Understanding Congressional Oversight in the Philippines: PDAF Scam to Flood Control Project Controversies in 2025

Congress, among its broad powers, also has the power of the purse or that it has the power to appropriate public funds. This is also exercised even after the general appropriations act has been passed for a specific year through its congressional oversight function. This article explores multiple facets of the congressional oversight function and what it means for the current flood control project anomalies.

What Is Congress Oversight? 

Congressional oversight is the power of the Philippine Congress to supervise the Executive branch and ensure laws are implemented efficiently and transparently.

Congress’ oversight function enables the two Houses: Senate & House of Representatives, to exercise supervision over the Executive branch & check if laws are being executed properly. Article VI, Section 21 of the 1987 Constitution additionally defines such as the ability of the Congress to call upon the heads of administrative agencies & departments, with the consent of the President, to appear and speak on any matter pertaining to their departments. 

Purpose of Congress Oversight: Checks and Accountability

While the separation of powers is a recognized legal doctrine, each branch of government is allowed the power to essentially “limit” the powers of the other through the system of “checks-and-balances” to avoid one branch from being too powerful. Congressional oversight is one such power where Congress can monitor the execution of laws by the Executive branch to ensure accountability, efficiency, and transparency. 

Difference Between Legislative Function vs. Oversight Function

Legislative function is the ability of Congress to make, alter, and repeal laws. Oversight function on the other hand, is the ability of Congress to monitor the activities of the Executive branch on the execution of laws.

Types of Congressional Oversight in the Philippines

Congressional oversight, although in itself a specific power of Congress, also contains kinds of powers in itself. These are defined in ABAKADA v. Purisima (2008):

• Scrutiny

Congressional scrutiny pertains to the least intrusive means of monitoring executive operations since it only aims to to determine efficiency of its operations. In this instance, Congress may request information and reports from the other branches of government. On the other hand, it can also give recommendations or pass resolutions for consideration of the agency involved.

Congressional scrutiny can be seen in action during budget hearings to ensure that the State’s money is properly disbursed according to the approved General Appropriations Act (GAA) of a particular year.

• Investigation 

By its name, congressional investigation involves intense digging & collecting needed facts for a particular purpose. This can be seen in Article VI, Section 21 of the 1987 Constitution and exercised in the form of Senate hearings in aid of legislation.

For instance, the Blue Ribbon Committee of the Senate has the ability to investigate “malfeasance, misfeasance, and nonfeasance in office by officers and employees of the government, its branches, agencies, subdivisions and instrumentalities.”

• Supervision

This type of Congressional oversight pertains to “a continuing and informed awareness on the part of a congressional committee regarding executive operations in a given administrative area”. 

This is an invalid form of Congressional oversight since it requires the executive branch to present their proposed implementing rules and regulations of a law to Congress which exercises its "right" or "power" to approve or disapprove such regulations yet again before they take effect.

Congress Oversight and Budget Implementation

In particular, Congress Oversight is important in budget implementation because it retains the power to ask for reports on how the budget of the State is being used after the GAA is passed for that year. This falls under Congressional scrutiny.

Role of COA in monitoring funds

The Commission on Audit or COA is a constitutional body (Article IX-D of the 1987 Constitution) which has the power to “examine, audit, and settle all accounts pertaining to the revenue and receipts of, and expenditures or uses of funds and property, owned or held in trust by, or pertaining to, the Government, or any of its subdivisions, agencies, or instrumentalities.” 

COA ensures, through the submission of financial statements and audit findings, that government expenditures are in line with the GAA for a specific year.

Budget Implementation Controversies: PDAF, DAP, and Flood Control Projects

Over the years, there have been several budget implementation controversies. The latest involves local flood control projects which yielded substandard constructions and “ghost” projects. A summary is provided for you to better understand these anomalies:

1. PDAF (Priority Development Assistance Fund)

• Definition: PDAF or the Priority Development Assistance Fund or colloquially known as pork barrel is a fund or budget item over which an individual member of Congress has discretion over its allocation and use even after the approval of the annual GAA.

• Summary: In 2013, 6 whistleblowers exposed such illegal activities involving the reallocation of the PDAF to “ghost” foundations and non-government organizations (NGOs) and directing them to the pockets of various public officials. 

• Where is it now: Eventually, through a series of Senate hearings and the ruling in Belgica v. Ochoa, this was struck down as an unconstitutional exercise of Congressional oversight since it encroaches on the power of the Executive branch to allocate the budget after GAA approval.

2. DAP (Disbursement Acceleration Program)

• Definition: DAP, on the other hand, is a Constitutional mechanism (Article VI, Section 25(5)) afforded to certain government entities such as the President, the Senate President, the Speaker of the House of Representatives, the Chief Justice of the Supreme Court, and the heads of Constitutional Commissions to “augment any item in the general appropriations law for their respective offices from savings in other items of their respective appropriations”

• Summary: Araullo v. Aquino III struck down some of the issuances and processes of the DAP which do not meet the requirements of a valid Constitutional augmentation:

  • There is a law authorizing such augmentation;

  • The funds to be transferred are savings generated from the appropriations for the respective offices; and

  • The purpose of the transfer is to augment an item in the general appropriations law for their respective offices.

• Where is it now: While the Court in Araullo v. Aquino III only struck down some of the processes that do not meet the said requirements, the administration of then-Benigno Aquino III stopped the implementation of DAP.

3. Flood Control Projects

• Definition: The flood control projects, as of today, were allegedly traceable to the unprogrammed budget allocations under annual GAAs. These unprogrammed budget allocations are standby funding for “priority programs and projects that are only released if government revenues exceed their targets, or if additional foreign grants or loans are secured”.

• Summary: One of the factors of the corruption involved in the controversial local flood control projects can be traced to the unprogrammed budget allocations which do not have definite funding at the time the annual GAA is prepared. Three parties are allegedly involved in this scheme: the legislator, the government engineer, and the corporations or contractors.

• Where is it now: It is currently under Congressional investigation under the Blue Ribbon Committee.

Limitations of Congress Oversight

While Congressional oversight seems like a broad power, it does have its limitations particularly from the Constitution.

• Separation of Powers

The structure of the 1987 Constitution would show that the 3 main branches of government: the legislative, executive, and judiciary have their independent powers to exercise. The doctrine of separation of powers seeks to maintain the balance of power between the branches of government in the Philippines.

As such, Congressional oversight must ensure that it does not encroach upon powers of the other branches beyond the aim of checks-and-balances.

• Non-Interference in Judicial Functions

While the Constitution expressly allows investigations in aid of legislation (Article VI, Section 21), the findings of the Congressional committees do not have the binding power of judicial decisions. As such, they cannot settle actual controversies involving legally demandable and enforceable rights.

• Privilege and Immunity

Executive privilege is extended to, not only the President, but also other high-ranking executive officials to withhold information pertaining to military, diplomatic, and national security matters and presidential communications. If invoked properly pursuant to the guidelines set in Neri v. Senate, this can limit the broad investigative powers under Congressional oversight.

Key Takeaways

• Congress exercises its oversight function to monitor the Executive's implementation of laws, including the proper use of public funds.

• These powers are limited by the separation of powers doctrine, non-interference in judicial functions, and executive privilege.

• The Commission on Audit (COA) plays a critical role in ensuring that government funds are spent in line with the approvedGeneral Appropriations Act (GAA).

• Over the years, there have been several budget implementation controversies: PDAF, DAP, and the current flood control projects scam.

• Supreme Court rulings like Belgica v. Ochoa (PDAF) and Araullo v. Aquino III (DAP) defined the limits of fund transfers and prohibited discretionary control over public funds.

• The recent flood control project anomalies show that corruption risks persist, emphasizing the continuing need for vigilant oversight, stronger transparency measures, and even independent cops monitoring to ensure accountability, along with active public participation in tracking budget implementation.

Frequently-Asked Questions (FAQs)

What is the difference between oversight and investigation?

Congressional investigation is one of the powers that can be exercised under Congressional oversight.

Conclusion

Budget implementation is usually the step that gets corrupted in government scams perpetuated by our very own public officials in partnership with private entities. Congress’s oversight function stands as a safeguard to ensure that every peso of public funds is used according to law and for the public good.

Yet, as past controversies like the PDAF scam and flood control project misuse reveal, oversight can only be effective when exercised within constitutional bounds and paired with transparency, active auditing, and citizen vigilance.

In 2025 and beyond, meaningful congressional oversight requires collaboration between Congress, COA, and the public to uphold integrity in governance, safeguard taxpayer money, and strengthen trust in democratic institutions.
