In the Philippine legal system, criminal actions are initiated through two distinct formal documents: a Complaint and an Information. While both serve the purpose of charging a person with an offense, they differ significantly in terms of their definition, the parties authorized to sign them, and their legal requirements under Rule 110 of the Revised Rules of Criminal Procedure.
I. Definitions and Legal Basis
The primary distinction between the two is found in Sections 3 and 4 of Rule 110:
- Complaint: A sworn written statement charging a person with an offense, subscribed by the offended party, any peace officer, or other public officer charged with the enforcement of the law violated.
- Information: An accusation in writing charging a person with an offense, subscribed by the prosecutor and filed with the court.
II. Key Differences
The differences can be categorized into four main areas: Signatory, Oath Requirement, Parties Involved, and Venue of Filing.
1. Subscription (Who Signs the Document)
- Complaint: It must be subscribed (signed) by the offended party, a peace officer, or a public officer tasked with enforcing the specific law violated (e.g., an NBI agent or a building official for building code violations).
- Information: It is subscribed exclusively by the public prosecutor (formerly referred to as the provincial or city fiscal).
2. Requirement of an Oath
- Complaint: It is a sworn statement. This means the person signing it must take an oath before an officer authorized to administer oaths.
- Information: It does not need to be sworn by the prosecutor. The rationale is that the prosecutor is already acting under a standing oath of office. However, the prosecutor must certify under oath that they have personally examined the complainant and witnesses and that there is reasonable ground to believe a crime has been committed.
3. Where It is Filed
- Complaint: It may be filed either with the Office of the Prosecutor (for the purpose of conducting a preliminary investigation) or, in certain instances, directly with the Municipal Trial Court or Municipal Circuit Trial Court.
- Information: It is always filed directly with the court (Regional Trial Court, Municipal Trial Court, etc.) once the prosecutor finds probable cause to proceed to trial.
4. Necessity for Prosecution
- Complaint: Generally, a criminal action starts with a complaint filed at the prosecutor's office. However, for "private crimes," a sworn complaint by the offended party is a jurisdictional requirement.
- Information: This is the standard document that brings a criminal case into the jurisdiction of the trial court for public crimes.
III. The Special Rule on Private Crimes
Under Section 5 of Rule 110, certain crimes cannot be prosecuted except upon a complaint filed by specific persons. This is a vital distinction because an Information alone, even if filed by a prosecutor, is insufficient to confer jurisdiction on the court for these offenses:
- Adultery and Concubinage: Can only be prosecuted upon a complaint filed by the offended spouse.
- Seduction, Abduction, and Acts of Lasciviousness: Can only be prosecuted upon a complaint filed by the offended party, her parents, grandparents, or guardian.
- Defamation (Libel/Slander): If it consists of the imputation of any of the above-mentioned private crimes, it must be prosecuted upon the complaint of the offended party.
IV. Summary Comparison Table
| Feature | Complaint | Information |
|---|---|---|
| Nature | A sworn written statement. | An accusation in writing. |
| Signatory | Offended party, peace officer, or authorized public officer. | Public Prosecutor. |
| Oath | Must be under oath. | No oath required (signed by virtue of office). |
| Filing | Filed with the Prosecutor or the Court (for MTC cases). | Filed with the Court. |
| Purpose | To initiate a preliminary investigation or a direct trial. | To formally charge the accused before a court of law. |
V. Legal Significance of the Distinction
The distinction is not merely formalistic; it is jurisdictional. If a case involving a "private crime" (such as Adultery) is filed via an Information signed by the prosecutor without a sworn Complaint from the offended spouse, the court does not acquire jurisdiction over the person of the accused or the subject matter. In such instances, the case may be dismissed at any stage of the proceedings, even on appeal, because the lack of a proper complaint is a fatal jurisdictional defect.
Conversely, for public crimes (like Theft or Homicide), while the process starts with a Complaint at the Prosecutor's level, it is the filing of the Information in court that formally marks the commencement of the criminal prosecution by the State.
