In the Philippine criminal justice system, the terms Arraignment and Preliminary Investigation represent two distinct stages of legal proceedings. To understand the procedure, one must first distinguish their purposes: the Preliminary Investigation determines whether there is "probable cause" to file a case in court, while Arraignment is the formal start of the trial where the accused enters a plea.
Under the Revised Rules of Criminal Procedure, the interplay between these two stages is critical for the protection of the constitutional rights of the accused.
I. The Nature of Preliminary Investigation
A Preliminary Investigation (PI) is an inquiry conducted by a public 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.
- When Required: It is mandatory for offenses where the penalty prescribed by law is at least four years, two months, and one day, without regard to the fine.
- The Goal: To secure the innocent against hasty, malicious, and oppressive prosecution, and to spare the State the useless expense of trials.
II. The Mechanism of Arraignment
Arraignment is the stage where the court informs the accused of the nature and cause of the accusation against them. It must be made in open court by the judge or clerk of court.
- Procedure: The complaint or information is read in a language or dialect known to the accused.
- The Plea: The accused is asked whether they plead guilty or not guilty.
- Refusal to Plead: If the accused refuses to plead or makes a conditional plea, a plea of not guilty shall be entered for them.
III. Arraignment Following Inquest (Warrantless Arrest)
A unique intersection occurs when a person is lawfully arrested without a warrant (e.g., in flagrante delicto).
- Inquest Proceedings: An informal and summary investigation conducted by a public prosecutor.
- Right to PI: Even if an Information (the formal charge) has been filed in court following an inquest, the accused may still ask for a Preliminary Investigation within five days after learning of the filing, provided they waive their right under Article 125 of the Revised Penal Code (Delay in the delivery of detained persons).
- Timing of Arraignment: If the accused moves for a PI after the case is filed, the court usually defers Arraignment until the prosecutor submits the result of the investigation.
IV. Grounds for Suspending Arraignment
Under Rule 116, Section 11, the Arraignment may be suspended upon motion by the accused on the following grounds relevant to the investigation phase:
- Petition for Review: When a petition for review of the resolution of the prosecutor is pending at either the Department of Justice (DOJ) or the Office of the President. The suspension shall not exceed sixty days from the filing of the petition with the reviewing office.
- Prejudicial Question: When a civil action exists that must be resolved first because its outcome determines whether the criminal case may proceed.
- Unsound Mental Condition: If the accused is found to be in a state of mind that prevents them from fully understanding the proceedings.
V. Important Jurisprudential Principles
The Supreme Court of the Philippines has established several rules regarding the timing of these procedures:
- Waiver of PI: If an accused undergoes Arraignment without first questioning the absence of a Preliminary Investigation, they are deemed to have waived their right to such investigation.
- No Interruption of Jurisdiction: The filing of a Motion for Reinvestigation or a Petition for Review does not automatically divest the court of jurisdiction. The court maintains the discretion whether to proceed with the Arraignment unless a restraining order is issued by a higher court.
- Presence of the Accused: Arraignment cannot proceed in absentia. The accused must be physically or virtually present (in authorized video conferencing hearings) to personally enter their plea.
VI. Summary of Procedural Flow
| Stage | Action |
|---|---|
| Filing | Prosecutor finds probable cause and files the "Information" in Court. |
| Warrant | The Judge evaluates the resolution and, if satisfied, issues a Warrant of Arrest. |
| Appearance | Accused is arrested or voluntarily surrenders (posts bail). |
| Arraignment | Court sets the date. The charge is read. Accused pleads. |
| Pre-Trial | Following a "Not Guilty" plea, the court schedules pre-trial to consider stipulations of facts. |
In the Philippine context, the integrity of the Arraignment process ensures that the State’s power to prosecute is balanced against the individual's right to due process and a fair trial.
