Below is a comprehensive, in-depth discussion of Rule 65 of the Rules of Court in the Philippines, which governs the special civil actions of Certiorari, Prohibition, and Mandamus. This includes their nature, distinctions, procedural requirements, common pitfalls, relevant jurisprudential guidance, and basic forms/format considerations. Although every effort has been made to be both detailed and accurate, always consult the latest jurisprudence and the text of the rules themselves for precision and updates.

I. OVERVIEW OF SPECIAL CIVIL ACTIONS UNDER RULE 65

A. Nature and Purpose

Rule 65 of the Rules of Court provides for three special civil actions:

Certiorari – Seeks to correct acts of a tribunal, board, or officer exercising judicial or quasi-judicial functions that amount to grave abuse of discretion amounting to lack or excess of jurisdiction.
Prohibition – Seeks to prevent (restrain) the commission or continuance of an act by a tribunal, corporation, board, or person, when the act is without or in excess of jurisdiction, or with grave abuse of discretion.
Mandamus – Seeks to compel the performance of a ministerial duty or to compel the exercise of discretion (when unlawfully neglected), or to compel the performance of duties by a corporation, board, tribunal, officer, or person.

Key Distinctions from Ordinary Actions and Other Remedies

Not a substitute for appeal. Rule 65 remedies lie only when there is no appeal or any other plain, speedy, and adequate remedy in the ordinary course of law.
Grounded on “lack or excess of jurisdiction” or “grave abuse of discretion”. These special civil actions address jurisdictional errors, not mere errors of judgment.
Provisional nature. They are extraordinary remedies granted only in exceptional circumstances.
Focus on immediate irreparable injury or injustice. Petitions under Rule 65 are designed to address situations that cannot be rectified by the normal appeal process (e.g., a patently void order or an obvious usurpation of power).

II. CERTIORARI (Rule 65, Section 1)

A. Definition and Requisites

A petition for certiorari is filed when:

The respondent (court, board, or officer) must be exercising judicial or quasi-judicial functions (i.e., having the power to determine what the law is, applying it to the facts, and the authority to render a definitive judgment).
The respondent acted without or in excess of jurisdiction, or with grave abuse of discretion amounting to lack or excess of jurisdiction.
There is no appeal, or any other plain, speedy, and adequate remedy in the ordinary course of law.

“Grave abuse of discretion” connotes capricious or whimsical exercise of judgment, equivalent to lack of jurisdiction. It must be such an abuse that it is tantamount to an evasion of a positive duty or a virtual refusal to perform the duty enjoined or to act at all in contemplation of law.

B. Period to File

Under the 2019 Amendments to the Rules of Court, the petition must be filed within 60 days from notice of the judgment, order, or resolution being assailed. If a motion for reconsideration or new trial is filed (when required), the 60-day period is counted from the notice of the denial of that motion.

In certain cases, the Supreme Court has relaxed the period on grounds of substantial justice, provided there is a compelling reason (e.g., to prevent manifest injustice or if extrinsic fraud prevented a timely filing). Nonetheless, this is an exception, not the rule.

C. Necessity of a Motion for Reconsideration

As a general rule, prior to availing of certiorari, a motion for reconsideration (MR) of the assailed order or judgment must first be filed before the same tribunal, board, or officer. The purpose is to give the lower court an opportunity to correct its error.

Exceptions to the MR requirement include (but are not limited to) situations where:

The issue is purely legal.
The action is patently void or the questioned order is a nullity.
A motion for reconsideration would be futile (e.g., the respondent is a prejudiced or a biased official).
Urgent necessity (e.g., to prevent irreparable injury) demands immediate court intervention.

D. Contents of the Petition (Rule 65, Sec. 1)

A petition for certiorari should contain:

Names of parties and their addresses.
A statement of material dates – specifically the date when the petitioner received the assailed order/judgment, the date of filing an MR (if any), and the date of receipt of the denial of such MR.
A concise statement of the matters involved.
The grounds relied upon for the petition – specifically pointing out the acts complained of as “without or in excess of jurisdiction” or “with grave abuse of discretion.”
Reliefs prayed for and a general prayer for such other reliefs as may be just or equitable.
Verification and certification against forum shopping.

E. Effect of Filing a Petition for Certiorari

Generally, the filing of a Rule 65 petition does not automatically stay the execution of the judgment or final order. The petitioner may file an application for a writ of preliminary injunction or a temporary restraining order (TRO) to maintain the status quo pending resolution of the petition.

III. PROHIBITION (Rule 65, Section 2)

A. Definition and Requisites

Prohibition is directed against a tribunal, corporation, board, officer, or person that is exercising functions judicial, quasi-judicial, or ministerial. The petitioner must show:

The respondent is about to exercise or is actually exercising judicial, quasi-judicial, or ministerial functions.
The exercise of such functions is without or in excess of jurisdiction, or with grave abuse of discretion amounting to lack or excess of jurisdiction.
No appeal or other plain, speedy, and adequate remedy in the ordinary course of law is available.

B. Nature of Prohibition

Prohibition is preventive rather than corrective.
It enjoins the respondent from further proceeding in the action or the performance of the act.
If the act has already been done or completed, the remedy is moot. However, the Supreme Court can decide on a “case capable of repetition yet evading review,” or if it has “transcendental importance.”

C. Period to File

Similar to certiorari, the 60-day rule applies, reckoned from notice of the act or proceeding sought to be restrained, or from the denial of a motion for reconsideration if required.

D. Formal Requirements and Procedure

Verified petition containing allegations similar to those in a petition for certiorari, including the statement of material dates and the certification against forum shopping.
The petitioner may also seek injunctive relief to prevent the respondent from continuing the challenged act during the pendency of the petition.

IV. MANDAMUS (Rule 65, Section 3)

A. Definition and Requisites

Mandamus compels:

The performance of an act which the law specifically enjoins as a duty resulting from office, trust, or station (i.e., a ministerial duty).
The exercise of discretion (where the respondent has unlawfully neglected the performance of a duty or excluded another from the use or enjoyment of a right or office to which the petitioner is entitled).

Requisites:

There is a clear legal right on the part of the petitioner to the performance of the act sought to be compelled.
It is the ministerial duty of the respondent to perform the act. If it is discretionary, mandamus may lie to compel the exercise of discretion but not to direct it in a particular manner, except in case of grave abuse in the exercise of such discretion.
No other plain, speedy, and adequate remedy is available in the ordinary course of law.

B. Ministerial vs. Discretionary Functions

A ministerial duty is one that requires obedience to a specific legal command—leaving no room for the exercise of judgment or discretion.
A discretionary duty involves the exercise of judgment, and mandamus can only compel the official to act or decide, not to decide in a specific way.

C. Period to File and Procedure

Although there is no strict 60-day period stated for mandamus in the same sense as certiorari or prohibition, the Supreme Court has applied the principle of laches and the policy of timeliness. Generally, it is safer practice to file it within a reasonable time from the occurrence of the violation of the right or refusal to perform the ministerial duty. If the matter arises from a quasi-judicial or judicial proceeding, the 60-day period may be applied analogously.

Petitions must be verified and must comply with the certification against forum shopping requirement, likewise stating the facts and the reliefs prayed for.

V. PROCEDURAL ASPECTS COMMON TO CERTIORARI, PROHIBITION, AND MANDAMUS

A. Jurisdiction and Venue

Supreme Court has concurrent jurisdiction with the Court of Appeals, the Regional Trial Courts (in certain cases), and the Sandiganbayan (in cases involving public officers within its jurisdiction) to issue writs of certiorari, prohibition, and mandamus.
Hierarchy of Courts – Although there is concurrent jurisdiction, the doctrine of hierarchy of courts dictates that petitions should generally be filed in the lowest court of competent jurisdiction capable of granting the relief. Direct recourse to the Supreme Court is allowed only in exceptional cases involving questions of constitutionality or if there are compelling reasons (e.g., national interest, unique or transcendental issues).

B. Remedies Available

Temporary Restraining Order (TRO) or Writ of Preliminary Injunction to preserve the status quo or to prevent further damage during the pendency of the case.
Issuance of a Peremptory Writ (in mandamus) if the court finds that petitioner has a clear right and the respondent has a clear duty.

C. Non-Extension of Period

Under the 2019 Amendments to the Rules of Court, the 60-day period is generally non-extendible. The only remedy is to file the petition within the reglementary period. Any extension is an exception that must be justified by compelling reasons.

D. Effects of Filing a Motion for Reconsideration or Appeal

As stated, a motion for reconsideration is generally a precondition before filing a Rule 65 petition (except under specific recognized exceptions).
If appeal is available and adequate, a petition under Rule 65 will not prosper. Rule 65 cannot be used to correct a mere error of judgment that can be reviewed on appeal.

E. Prohibition Against Forum Shopping

The petition must contain a Certification against Forum Shopping.
Any violation may result in dismissal of the petition or even administrative sanctions for the lawyer or the parties.

VI. COMMON PITFALLS AND PRACTICE POINTERS

Mistaking Error of Judgment for Grave Abuse of Discretion
- A mere error of judgment or misapplication of law does not automatically amount to grave abuse of discretion. The error must be so patent and gross as to constitute an evasion of a positive duty.
Improper Availment of Rule 65 as a Substitute for a Lost Appeal
- If the petitioner fails to appeal on time, a Rule 65 petition cannot be used to revive the case unless very compelling grounds exist.
Failure to Prove Clear Legal Right or Ministerial Duty (in Mandamus)
- The petition will fail if the duty is not plainly ministerial or if the petitioner’s right to the performance of the act is not clearly established.
Failure to Observe the 60-Day Period
- The courts strictly enforce the 60-day period, subject only to exceptional grounds for a liberal application.
Non-Compliance with Motion for Reconsideration Requirement
- Omitting to file a mandatory MR before resorting to Rule 65 is a fatal defect, unless the situation fits one of the recognized exceptions.

VII. RELEVANT JURISPRUDENCE

Cisco Philippines, Inc. v. Alcuizar, G.R. No. 253617, September 8, 2021 – Reiterates the requirement of a motion for reconsideration before filing a petition for certiorari and the exceptions thereto.
Ramos v. People, 792 SCRA 206 – Explains grave abuse of discretion and clarifies when Rule 65 petitions are appropriate.
St. Martin Funeral Home v. NLRC, 295 SCRA 494 (1998) – Leading case on the doctrine of hierarchy of courts and the procedure for labor cases falling under Rule 65 in the Court of Appeals.
Uy v. Office of the Ombudsman, 702 SCRA 75 – Highlights that the availability of an appeal is fatal to a petition for certiorari unless extremely exceptional circumstances exist.
Gallardo-Corro v. Gallardo, 747 SCRA 31 – Clarifies that in mandamus, the duty to be compelled must be ministerial and not discretionary.

VIII. LEGAL ETHICS CONSIDERATIONS

Duty of Candor
- The lawyer must fully disclose all relevant material dates in the petition and must not mislead the court regarding the timeliness of the petition.
Certification Against Forum Shopping
- The lawyer must ensure that no other similar action or proceeding is pending before another tribunal. Misrepresentation or deliberate omissions can subject counsel and client to sanctions.
Avoid Frivolous Filings
- Frivolous petitions under Rule 65 (used merely to delay proceedings) can lead to the imposition of damages or administrative penalties.
Respect the Doctrine of Hierarchy of Courts
- Counsel should file in the correct forum unless a clear exception applies (e.g., a novel question of law that must be settled immediately by the Supreme Court).

Note:

For Prohibition, the prayer would focus on enjoining the respondent from continuing the challenged act.
For Mandamus, the prayer would demand the respondent to perform a specific, ministerial duty.

X. CONCLUSION

Rule 65 petitions for Certiorari, Prohibition, and Mandamus are extraordinary remedies aimed at correcting jurisdictional errors and compelling lawful performance of duties. They cannot be used as a substitute for appeal, nor can they cure mere errors of judgment. The 60-day rule, the requirement of a prior motion for reconsideration, and the doctrine of hierarchy of courts are the principal gatekeepers ensuring that only meritorious cases are entertained.

Legal ethics demands candor, fair dealing, and compliance with all formal requirements to avoid dismissal and potential sanctions. When drafting petitions or responding to them, thorough attention to detail, meticulous factual and legal groundwork, and timely filing are critical to a successful Rule 65 recourse.
