I. INTRODUCTION
This memorandum addresses the legal framework governing warrantless arrests and the subsequent inquest proceedings under Philippine law. The rules are primarily codified in Rule 113 (Arrest) and Rule 112 (Inquest) of the Revised Rules of Criminal Procedure. These procedures balance the state’s duty to apprehend offenders with the constitutional right of persons against unreasonable seizures.
II. WARRANTLESS ARRESTS: GENERAL RULE AND EXCEPTIONS
As a general rule, an arrest requires a judicial warrant issued upon a finding of probable cause. However, Section 5, Rule 113 of the Revised Rules of Criminal Procedure provides the exceptions when a warrant is not necessary:
a. When, in the presence of the arresting officer, the person to be arrested has committed, is actually committing, or is attempting to commit an offense (in flagrante delicto).
b. When an offense has just been committed, and the arresting officer has probable cause to believe, based on personal knowledge of facts or circumstances, that the person to be arrested committed it (hot pursuit).
c. When the person to be arrested is a prisoner who has escaped from a penal establishment or place where he is serving final judgment or temporarily confined while his case is pending, or has escaped while being transferred from one confinement to another.
d. When the person arrested, while in custody, voluntarily admits the commission of another offense.
Any arrest not falling under these exceptions is deemed unlawful.
III. REQUIREMENTS FOR A VALID IN FLAGRANTE DELICTO ARREST
For a valid in flagrante delicto arrest, two elements must concur: (1) the person to be arrested must execute an overt act indicating that he has just committed, is actually committing, or is attempting to commit a crime; and (2) such overt act is done in the presence or within the view of the arresting officer. The officer’s personal knowledge is crucial; mere suspicion or hearsay information is insufficient.
IV. REQUIREMENTS FOR A VALID HOT PURSUIT ARREST
For a valid warrantless arrest under the “hot pursuit” exception, the following must be present: (1) an offense has just been committed; and (2) the arresting officer has probable cause to believe, based on personal knowledge of facts or circumstances, that the person to be arrested committed it. “Personal knowledge” means knowledge derived from the officer’s own perception, not from information supplied by another person. The element of immediacy in time between the crime and the arrest is essential.
V. DUTY OF ARRESTING OFFICER IN WARRANTLESS ARRESTS
A person arrested without a warrant must be informed, at the time of arrest, of the reason for the arrest and his constitutional rights to remain silent and to counsel (Section 2, Article III, 1987 Constitution). He must be delivered to the nearest police station or jail without unnecessary delay. The officer must then prepare a written report stating the facts and circumstances of the arrest, which shall be submitted to the prosecutor for inquest.
VI. INQUEST PROCEEDINGS: PURPOSE AND PROCEDURE
An inquest is an informal and summary investigation conducted by a public prosecutor to determine the existence of probable cause for the detention of a person arrested without a warrant. It is governed by Rule 112, Sections 3-7 of the Revised Rules of Criminal Procedure. The primary purpose is to decide whether the arrested person should remain in custody and be charged in court, or be released for further preliminary investigation or outright.
VII. RIGHTS OF THE ARRESTED PERSON DURING INQUEST
During the inquest, the arrested person has the right to be informed of the nature of the inquiry. While the Rules do not explicitly grant the right to present counter-affidavits or witnesses during the summary inquest, the arrested person has the right to counsel. If the prosecutor finds no probable cause, the arrested person shall be released immediately. If the prosecutor finds probable cause, but the arrested person was not lawfully arrested (i.e., the arrest does not fall under Section 5, Rule 113), the prosecutor may order the person’s release and require the filing of a complaint for a regular preliminary investigation.
