Preliminary Investigation under Rule 112 of the Rules of Court
Preliminary investigation is a critical procedural step in the Philippine criminal justice system. It is governed by Rule 112 of the Rules of Court, which provides the framework for determining whether there exists probable cause to charge a person with a criminal offense. Below is a meticulous breakdown of all significant aspects of preliminary investigation under Rule 112.
I. Nature and Purpose of Preliminary Investigation
Definition: A preliminary investigation is an inquiry or proceeding conducted by a prosecutor to determine whether there is sufficient ground to engender a well-founded belief that a crime has been committed and that the respondent is probably guilty thereof, and should be held for trial.
Purpose:
- To protect the respondent from the inconvenience, expense, and burden of a public trial unless there is prima facie evidence of guilt.
- To safeguard the State from prosecuting a case that lacks merit.
Nature: Preliminary investigation is not a trial. It is not meant to establish the guilt or innocence of the respondent but only the probability of guilt.
II. Who May Conduct Preliminary Investigation
Under Section 2, Rule 112, the following officials have authority to conduct preliminary investigations:
- Provincial or City Prosecutors and their assistants.
- State Prosecutors.
- Other officers authorized by law, such as the Ombudsman in cases of graft and corruption, and the Presidential Anti-Corruption Commission (PACC) in cases under its jurisdiction.
Note: Municipal Trial Court Judges may conduct a preliminary examination in cases where arrest warrants are needed, but this does not constitute a full preliminary investigation.
III. Cases Subject to Preliminary Investigation
Threshold Amount of Penalty:
- A preliminary investigation is required for offenses punishable by at least four (4) years, two (2) months, and one (1) day without regard to fine.
- For offenses punishable by lower penalties, the filing of a complaint or information may proceed without a preliminary investigation.
Exceptions: When the penalty is less than the threshold but a preliminary investigation is mandated by specific laws or regulations, this procedure applies.
IV. Procedure in Preliminary Investigation
The process of preliminary investigation is outlined in Sections 3 to 5 of Rule 112. It involves the following steps:
1. Filing of the Complaint (Section 3)
- Where to File: The complaint is filed with the Office of the Prosecutor or the officer authorized to conduct a preliminary investigation.
- Form and Contents:
- The complaint must be in writing, under oath, and supported by the complainant's affidavit and the affidavits of witnesses.
- Copies of other supporting documents should also be attached to establish probable cause.
2. Issuance of Subpoena (Section 3)
- If the prosecutor finds that the complaint and supporting documents establish probable cause, a subpoena is issued to the respondent.
- The subpoena requires the respondent to submit a counter-affidavit and supporting evidence within a period of ten (10) days from receipt.
3. Submission of Counter-Affidavits and Evidence (Section 3)
- The respondent must:
- File a counter-affidavit, under oath, responding to the allegations.
- Attach affidavits of witnesses and supporting documents.
- Failure to submit a counter-affidavit is considered a waiver of the respondent’s right to present evidence, and the investigation proceeds based on the evidence of the complainant.
4. Clarificatory Hearing (Optional, Section 3)
- The investigating officer may conduct clarificatory hearings to ask questions and gather additional information.
- Both parties may be present during the hearing but cannot cross-examine each other.
5. Resolution of the Prosecutor (Section 4)
- After reviewing the affidavits and evidence, the investigating prosecutor resolves whether:
- Probable cause exists to file an information in court.
- The complaint should be dismissed.
- The resolution must be in writing and state the findings and reasons for the decision.
V. Review and Appeals
Review by the Provincial or City Prosecutor (Section 4):
- The resolution of an investigating prosecutor is subject to review by the Provincial Prosecutor or City Prosecutor.
Appeal to the Secretary of Justice:
- If dissatisfied with the prosecutor’s decision, a party may file a petition for review with the Secretary of Justice within fifteen (15) days from receipt of the resolution.
- The decision of the Secretary of Justice is final and executory in criminal cases but can still be questioned in court.
Judicial Review:
- The resolution may be subject to certiorari under Rule 65 if there is grave abuse of discretion amounting to lack or excess of jurisdiction.
VI. Exceptions to Preliminary Investigation
Certain cases do not require a preliminary investigation:
Inquest Proceedings:
- When a person is lawfully arrested without a warrant, an inquest proceeding is conducted to determine the existence of probable cause for filing an information.
- The detained person may opt to undergo a full preliminary investigation by signing a waiver of detention under Article 125 of the Revised Penal Code.
Direct Filing of Complaint:
- In cases punishable by less than four (4) years, two (2) months, and one (1) day.
VII. Rights of the Respondent in Preliminary Investigation
The respondent enjoys several rights during a preliminary investigation:
- Right to be informed of the complaint against them.
- Right to submit counter-affidavits and evidence.
- Right to counsel.
- Right to be notified of all proceedings.
- Right to an impartial and objective investigation.
VIII. Remedies Against Prosecutor’s Findings
The respondent or complainant may avail the following remedies:
- Motion for Reconsideration:
- File with the investigating prosecutor or reviewing authority.
- Appeal to the Secretary of Justice:
- Elevate the matter to the Secretary of Justice within the prescribed period.
- Filing a Petition for Certiorari:
- If there is grave abuse of discretion, file a petition for certiorari under Rule 65 with the appropriate court.
IX. Relation to Legal Ethics
- Prosecutors must conduct preliminary investigations in strict observance of the principles of due process and impartiality.
- Canon 6, Rule 6.01 of the Code of Professional Responsibility emphasizes that prosecutors should not initiate charges when there is no probable cause.
- Rule 10.03: Lawyers must not knowingly use false evidence or induce witnesses to lie.
X. Forms Used in Preliminary Investigation
- Complaint-Affidavit: Sworn statement of the complainant outlining the facts constituting the offense.
- Subpoena: Official notice issued by the investigating prosecutor.
- Counter-Affidavit: Respondent's sworn reply to the allegations.
- Resolution: Prosecutor's written finding on the existence or absence of probable cause.
XI. Jurisprudential Updates
Courts have consistently emphasized the discretionary power of prosecutors in preliminary investigations. Significant rulings include:
- Bernardo v. Court of Appeals (G.R. No. 119010): Preliminary investigation is not a constitutional right but a statutory privilege.
- Cruz v. People (G.R. No. 164238): The absence of a preliminary investigation does not impair the validity of the proceedings if the accused fails to raise the issue at the earliest opportunity.
This exhaustive treatment of Rule 112 ensures compliance with legal and ethical standards in preliminary investigations, preserving the balance between prosecutorial discretion and individual rights.
