Hot Pursuit Arrests: When Is a Warrant Required in the Philippines

In Adoma v. People (G.R. No. 240126, April 12, 2023), the Supreme Court acquitted a man convicted of illegal drug possession, ruling that the warrantless "hot pursuit" arrest that led to his seizure was invalid. The case clarifies when police may arrest without a warrant and what happens when they overstep those limits.

The Facts of the Case

On September 21, 2013, a homeowner reported to the Laoag City police that his house had been robbed. Among the missing items were laptops, tablets, watches, and cash. That evening, the victim used GPS tracking to locate his stolen laptops at the house of Caesar Martin Pascua.

Pascua told police that Jamel Adoma had brought the items to him for password unlocking and reformatting. Police brought Pascua to the station for further investigation. When Adoma called to ask if the laptops were ready, police instructed Pascua to say yes. An entrapment operation followed at Pascua's house, where police arrested Adoma. A search of his body yielded two plastic sachets of shabu.

Adoma was charged with illegal possession of dangerous drugs under Section 11 of Republic Act No. 9165. He was convicted by the Regional Trial Court and the Court of Appeals affirmed. He appealed to the Supreme Court.

The Issue: Was the Warrantless Arrest Valid?

The Supreme Court explained that for a valid hot pursuit arrest under the Rules of Criminal Procedure, two elements must concur:

1. Personal knowledge — police must have personal knowledge of facts, based on their own observation, that the person sought has just committed a crime. A tip or report from another person is not enough.
2. Immediacy — the arrest must happen within a limited time from the commission of the offense. The facts must be gathered within a very limited period of time, not after an exhaustive investigation.

Applying the Rule to the Facts

The Court found that both elements were missing.

On personal knowledge: The police acted solely on the victim's report and the GPS tracking. They never verified the information themselves. When they went to Pascua's house, they realized he was not the culprit. It was only through another unverified tip—from Pascua—that they concluded Adoma was the robber. This was not personal knowledge based on police observation.

On immediacy: The crime was reported in the morning, but Adoma was arrested around 7:00 p.m. the same day. In between, police conducted further investigation and brought Pascua to the station. The Court held this wide time gap meant the arrest was based on an exhaustive investigation, not the kind of spontaneous pursuit the rule contemplates.

The Effect of an Invalid Arrest

Adoma did not question the validity of his arrest before arraignment, so he waived his right to challenge it. However, the Court stressed a crucial point: waiving the illegality of an arrest does not make the evidence seized admissible.

Because the arrest was invalid, the search incidental to it was also invalid. The seized shabu was inadmissible under the exclusionary rule of the 1987 Constitution. Without that evidence, Adoma had to be acquitted.

The Chain of Custody Rule Under Section 21, RA 9165

Even if the drugs had been admissible, the Court found the prosecution failed the chain of custody rule.

Section 21 of RA 9165 requires police to physically inventory and photograph seized drugs immediately after seizure, in the presence of the accused, a representative from the media, a representative from the Department of Justice, and an elected public official.

The rule has a saving clause: non-compliance will not invalidate the seizure if there are justifiable grounds and the integrity and evidentiary value of the items are preserved. But the prosecution must acknowledge and justify any deviation.

In this case, the police took no photographs at all of the seized items. The required witnesses were absent, and the barangay chair whose presence was claimed apparently did not sign the inventory. The lower courts glossed over these lapses and focused only on the movement of the drugs. The Court held these unjustified deviations created a substantial gap in the chain of custody, casting doubt on the integrity of the evidence.

Practical Takeaways

• A tip is not personal knowledge. Police cannot rely solely on a complainant's report or another person's statement to justify a hot pursuit arrest. They must have their own observation of facts indicating the person committed the crime.
• Immediacy matters. The longer the gap between the crime and the arrest, the harder it is to justify a warrantless arrest. Extended investigation calls for a warrant.
• An invalid arrest taints the search. Evidence seized in a search incidental to an unlawful arrest is inadmissible in court, even if the accused fails to object to the arrest itself.
• Chain of custody is substantive law. Police must strictly follow Section 21 of RA 9165. Deviations must be justified, and the prosecution must explain them—otherwise, the seized drugs may be excluded.
• For drug cases, procedure is everything. Even when police have a strong case on the merits, procedural lapses in arrest and evidence handling can lead to acquittal.
