Unreasonable Search Evidence Obtained Illegally IS Inadmissible IN Drug Cases

The Supreme Court has reaffirmed a fundamental rule in criminal procedure: evidence seized through an unreasonable search cannot be used against an accused. In Sio v. People (G.R. No. 224935, March 2, 2022), the Court dismissed drug charges against a man whose home was searched under a warrant that police implemented improperly. The ruling is a reminder that the Constitution's protection against unreasonable searches is not merely symbolic—it has real consequences for prosecution.

The Facts of the Case

In 2010, police applied for a search warrant against Antonio Sio, a businessman suspected of keeping shabu in his Lucena City residence. The warrant specifically described the place to be searched as "Ilaya Ibaba, Purok 34, Barangay Dalahican" and listed a Toyota Camry (plate ZYR 468) and a Honda Civic (plate ZGS 763) as vehicles to be seized.

When police implemented the warrant on October 24, 2010, several things went wrong. The search happened at a different location—Barangay Purok 3A, not Purok 34. The vehicles seized were a different CRV Honda (XPX 792) and Toyota Camry (ZRY 758), not the ones listed in the warrant. The Land Transportation Office later certified that the vehicle plate number in the warrant did not exist.

More troubling, the police officers admitted that they entered Sio's residence without the presence of media representatives, barangay officials, or Department of Justice personnel. These witnesses only arrived three hours later. The search was also conducted without the lawful occupant or any family member present.

The Legal Issues

The case raised two main questions: (1) Was the implementation of the search warrant unreasonable, making the seized evidence inadmissible? and (2) Was there probable cause to charge Sio with violating Sections 11 and 12 of Republic Act No. 9165 (the Comprehensive Dangerous Drugs Act)?

The Court's Ruling

The Supreme Court ruled in favor of Sio, reversing the Court of Appeals and dismissing the criminal cases against him.

The search was unreasonable. The Constitution requires search warrants to particularly describe the place to be searched and the persons or things to be seized. The purpose of this requirement is to prevent police from having discretion over where they search and what they seize. Here, the police searched a different place and seized different vehicles than those specified in the warrant. The Court cited People v. Court of Appeals: a warrant cannot be amplified or modified by the officers' own knowledge—the particularization must be done by the judge, in the warrant itself.

Section 21 of RA 9165 was violated. The Court clarified that the chain of custody requirements under Section 21 apply not only to buy-bust operations but also to searches conducted under a warrant. The law requires that after seizure, the drugs be inventoried and photographed in the presence of: (1) the accused or their representative, (2) a media representative, (3) a DOJ representative, and (4) an elected public official.

In this case, none of these witnesses were present when police entered. The media and barangay officials arrived three hours later. The prosecution offered no justification for this failure. As the Court noted, when police operate under a search warrant, they have the advantage of planning ahead—there is no excuse for failing to secure the required witnesses.

The evidence was inadmissible. Because the search was unreasonable and the chain of custody requirements were not met, the seized drugs and paraphernalia could not be used as evidence. Without this evidence, there was no probable cause to support the charges. The Court ordered the cases dismissed and the seized items returned, except for the shabu and paraphernalia, which were forfeited to the State.

Practical Takeaways

• Search warrants are specific, not general. Police can only search the place and seize the items described in the warrant. Any deviation enlarges the scope and makes the search unreasonable.
• Section 21 applies to all drug seizures. Whether from a buy-bust or a search warrant, police must follow the chain of custody rules—inventory and photograph the drugs in the presence of the required witnesses.
• Witnesses must be present at the time of seizure. Their presence is meant to prevent planting, switching, or contamination of evidence. Arriving hours later defeats the purpose.
• The prosecution must explain any non-compliance. The "saving clause" in Section 21 only applies if there are justifiable grounds for non-compliance AND the integrity of the evidence is preserved. Both requirements must be met.
• Illegally obtained evidence cannot support a charge. If the evidence is inadmissible, there is no basis for probable cause, and the case may be dismissed.
