SUBJECT: The Concept of ‘The Quasi-Judicial Power’ (Adjudicatory Power) and Administrative Due Process

I. Introduction

This memorandum provides an exhaustive analysis of the concept of quasi-judicial power (also termed adjudicatory power) as exercised by administrative agencies in the Philippine legal system, and its inextricable link to the constitutional and jurisprudential requirements of administrative due process. The expansion of the administrative state has necessitated the delegation of decision-making authority to specialized bodies. While these agencies perform executive or regulatory functions, the power to hear and decide matters involving rights and obligations through a contested proceeding is quasi-judicial in character. This memo will delineate the nature, source, and scope of this power, the constitutional safeguards that attach to its exercise, and the procedural requirements that constitute administrative due process.

II. Definition and Nature of Quasi-Judicial Power

Quasi-judicial power refers to the authority vested by law upon an administrative officer or agency to hear and determine, after a proceeding where facts are ascertained and legal consequences are applied, the rights and obligations of contending parties. It is “adjudicatory” in nature, meaning it involves a determination akin to a court’s judgment, but it is exercised by a body that is not part of the judiciary. The Supreme Court has defined it as “the power to hear and determine questions of fact to which the legislative policy is to apply and to decide in accordance with the standards laid down by the law itself in enforcing and administering the same law.” The power is not inherent in administrative agencies; it must be expressly granted by statute or be necessarily implied from the statutory duties conferred upon the agency.

III. Source and Delegation of Quasi-Judicial Power

The quasi-judicial power of administrative agencies is a derivative of the principle of delegation of legislative authority. Under the Constitution, Congress may validly delegate to administrative agencies the power to “fill in the details” in the execution of a declared legislative policy. This is known as the power of subordinate legislation or rule-making. However, Congress may also delegate the power to apply these rules and regulations to specific situations in a contested proceeding, which is the adjudicatory or quasi-judicial power. This delegation is permitted provided the law is complete in itself (setting forth the policy to be implemented) and fixes a standard—which may be broad and flexible—to limit the agency’s discretion. The standard ensures that the agency’s exercise of its quasi-judicial power is not arbitrary and is confined within the legislative policy.

IV. Distinction from Other Powers

It is crucial to distinguish quasi-judicial power from other powers of administrative agencies:
1. Ministerial Power: A duty that is absolute and imperative, requiring simple execution in obedience to the law, without discretion. Quasi-judicial power involves discretion and judgment.
2. Discretionary Power: The power to choose among alternatives, but not necessarily in a contested proceeding. All quasi-judicial acts involve discretion, but not all discretionary acts are quasi-judicial.
3. Investigatory Power: The power to inquire into facts for legislative or informational purposes. It does not, by itself, result in a binding order affecting rights. Quasi-judicial power includes investigation but culminates in a binding adjudication.
4. Rule-Making Power (Legislative): The power to issue rules and regulations of future application. Quasi-judicial power is concerned with the application of existing laws or rules to past or present facts concerning specific parties.

V. Constitutional Foundation: The Due Process Clause

The exercise of quasi-judicial power is circumscribed by the constitutional guarantee of due process, found in Article III, Section 1 of the 1987 Constitution: “No person shall be deprived of life, liberty, or property without due process of law.” This clause applies with full force to administrative proceedings. Administrative due process is the adaptation of judicial due process to the administrative setting, recognizing that while agencies are not courts, their decisions can have equally grave consequences on individual rights. The essence of due process in administrative proceedings is the opportunity to be heard and to seek reconsideration.

VI. Elements of Administrative Due Process

Jurisprudence has established that the fundamental requirements of administrative due process in the exercise of quasi-judicial power are:

The right to a hearing: The party must be given an opportunity to present their case, submit evidence, and argue their position. This includes the right to know the claims of the opposing party.

The tribunal must consider the evidence presented: The decision must be rendered based on the evidence offered at the hearing or contained in the record.

The decision must have something to support itself: The finding must be supported by substantial evidence, which is defined as such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.

The evidence must be substantial: The substantial evidence rule is the standard of review for quasi-judicial bodies. It is less stringent than proof beyond reasonable doubt or preponderance of evidence but requires more than a mere scintilla.

The decision must be rendered on the evidence presented at the hearing, or at least contained in the record and disclosed to the parties: No ex parte communications or secret evidence may form the basis of the decision.

The tribunal or body must act on its own independent consideration of the facts and the law of the case, and not simply accept the views of a subordinate: This is the doctrine of non-delegation of adjudicatory authority.

The decision must be rendered in such a manner that the parties can know the various issues involved and the reasons for the decision: This is often fulfilled by a written decision stating the basic facts and the legal basis for the conclusion.

VII. Comparative Analysis: Judicial vs. Quasi-Judicial Due Process

The following table compares the application of due process in judicial proceedings and in administrative quasi-judicial proceedings.

Aspect of Due Process	Judicial Proceedings (Courts)	Quasi-Judicial Proceedings (Administrative Agencies)
Source of Authority	Inherent judicial power derived directly from the Constitution.	Statutorily delegated power; must be expressly granted by law.
Governing Procedure	Strict adherence to the Rules of Court (e.g., Rules of Civil/Criminal Procedure).	Governed by the agency’s own rules of procedure, provided they comply with fundamental due process. Simplicity and flexibility are emphasized.
Presiding Officer	A judge, appointed under strict constitutional qualifications.	An administrative official, hearing officer, or a multi-member commission, with qualifications set by statute.
Standard of Proof	Varies: Preponderance of evidence (civil), proof beyond reasonable doubt (criminal), clear and convincing evidence (special cases).	Generally, substantial evidence. For disciplinary cases leading to dismissal, substantial evidence is required.
Right to Counsel	A fundamental right, especially in criminal cases.	Generally, the right to counsel exists, but the right to competent and independent counsel may not be absolute; one can often be represented by a non-lawyer within the agency.
Rules of Evidence	Technical rules of evidence strictly apply.	Technical rules of evidence are not controlling; agencies may rely on evidence of a kind commonly relied upon by reasonable persons.
Finality of Decision	Generally appealable to higher courts.	Decisions become final after exhaustion of administrative remedies (e.g., motion for reconsideration, appeal to a higher agency level). Judicial review via a petition for certiorari under Rule 65 is available thereafter.
Scope of Judicial Review	Varies (e.g., review of facts and law in appeals).	Generally limited to questions of jurisdiction, grave abuse of discretion, or lack of substantial evidence. Courts do not re-weigh evidence.

VIII. Exceptions to the Hearing Requirement

The requirement of a formal hearing is not absolute in administrative proceedings. The essence of due process is simply an opportunity to be heard. Exceptions or flexible applications include:

Summary Proceedings: Allowed in cases of urgency or where public interest requires immediate action (e.g., summary abatement of a nuisance, suspension of a license to prevent imminent harm).

When the issue is purely one of law: Where the facts are not in dispute, a hearing on facts may be dispensed with.

Legislative-type decisions: When an agency is making broad policy decisions affecting a class, rather than adjudicating individual rights.

Where a party waives their right to a hearing: Through inaction, failure to appear, or explicit waiver.

Preliminary investigations: Which are merely for the determination of probable cause and do not constitute a final adjudication.

IX. Judicial Review of Quasi-Judicial Actions

Decisions of administrative agencies exercising quasi-judicial power are subject to judicial review. The primary remedy is a petition for certiorari under Rule 65 of the Rules of Court, alleging that the agency acted without or in excess of jurisdiction, or with grave abuse of discretion amounting to lack or excess of jurisdiction. The doctrine of exhaustion of administrative remedies requires that parties must first avail themselves of all remedies within the administrative machinery before seeking judicial intervention. The complementary doctrine of finality of administrative action (or doctrine of primary jurisdiction) holds that courts will not interfere with ongoing administrative proceedings. On review, courts generally accord finality and respect to administrative findings of fact, especially when supported by substantial evidence, as agencies are considered experts in their fields.

X. Conclusion

The quasi-judicial power is a necessary and potent tool of the modern administrative state, enabling specialized bodies to resolve disputes efficiently within their regulatory domains. However, its exercise is not unfettered. It is anchored in a valid statutory grant and, more importantly, is enveloped by the constitutional mantle of due process. Administrative due process, while flexible and tailored to the practical needs of agency proceedings, guarantees the core rights of notice, hearing, and a decision based on evidence. The substantial evidence rule serves as the critical bridge between administrative efficiency and factual reliability. Judicial review, though circumspect, remains the ultimate safeguard against arbitrariness, ensuring that the exercise of adjudicatory power by administrative bodies remains within the bounds of law, fairness, and reason.
