Compliance with Section 7

Rule 112

Section 7. When accused lawfully arrested without warrant. — When a person is lawfully arrested without a warrant involving an offense which requires a preliminary investigation, the complaint or information may be filed by a prosecutor without need of such investigation provided an inquest has been conducted in accordance with existing rules. In the absence or unavailability of an inquest prosecutor, the complaint may be filed by the offended party or a peace office directly with the proper court on the basis of the affidavit of the offended party or arresting officer or person.

Before the complaint or information is filed, the person arrested may ask for a preliminary investigation in accordance with this Rule, but he must sign a waiver of the provisions of Article 125 of the Revised Penal Code, as amended, in the presence of his counsel. Notwithstanding the waiver, he may apply for bail and the investigation must be terminated within fifteen (15) days from its inception.

After the filing of the complaint or information in court without a preliminary investigation, the accused may, within five (5) days from the time he learns of its filing, ask for a preliminary investigation with the same right to adduce evidence in his defense as provided in this Rule.
