Exclusionary Rule Bars Illegal Drug Evidence From Unreasonable Search

Supreme Court acquits drug suspect after police violated search rules, applying the exclusionary rule to suppress seized shabu evidence.


The right against unreasonable searches and seizures is a cornerstone of Philippine criminal procedure. When police officers violate this right, the evidence they obtain becomes inadmissible in court—no matter how compelling the case against the accused. In People v. Go (G.R. No. 144639, September 12, 2003), the Supreme Court demonstrated the full force of this exclusionary rule, overturning a conviction for illegal drug possession because the search that produced the evidence was tainted with multiple irregularities.

The Case Against Benny Go

Police officers conducted a "test buy" operation at Benny Go's residence in Manila, purchasing P1,500.00 worth of shabu. Instead of arresting him immediately, they applied for and obtained a search warrant for his house. On June 14, 1999, a raiding team arrived at Go's residence to execute the warrant.

The officers deliberately sideswiped Go's parked car to gain entry. Once inside, they handcuffed Go's son Jack to a chair, even though he had shown no aggression. The search proceeded from 6:00 to 11:00 in the evening, with the police recovering what they claimed was 204 grams of shabu from a cabinet drawer. They also seized numerous items unrelated to illegal drugs—passports, bank books, checks, a typewriter, dry seals, and currency.

Go was convicted by the trial court and sentenced to reclusion perpetua and a fine of P1,000,000.00. The trial court relied on the presumption of regularity in the performance of official duty and an "Affidavit of Orderly Search" signed by Go and witnesses.

The Issue

The central question was whether the search of Go's residence was conducted in accordance with the constitutional requirements for valid searches and seizures—and if not, whether the seized evidence should be excluded.

The Supreme Court's Ruling

The Supreme Court acquitted Go, ruling that the search was unreasonable and the evidence inadmissible. The Court identified several fatal irregularities in how the police conducted the search.

Violation of the knock-and-announce rule. The police deliberately sideswiped Go's car to gain entry instead of following the regular procedure of announcing their presence and authority. There was no showing that prior notice would have endangered the warrant's implementation.

Unjustified restraint of a family member. Jack Go was immediately handcuffed to a chair without any provocation. The Court found this forcible restraint unjustified, especially since it continued even after barangay officials arrived.

Search conducted without required witnesses. Under Section 8, Rule 126 of the Rules of Court, a search must be conducted in the presence of the lawful occupant or a family member, or in their absence, two witnesses from the locality. Here, the search of the upper floor—where the shabu was allegedly found—occurred while Go was away and his son was handcuffed downstairs. The barangay kagawads who witnessed the search were assigned to different areas, meaning the actual recovery of the drugs was not properly witnessed.

Seizure of unrelated items. The police seized numerous items clearly outside the scope of the search warrant, which only authorized the seizure of shabu, weighing scales, drug paraphernalia, and proceeds of the drug offense.

Defective inventory and receipt. The police failed to provide a detailed inventory of seized items, did not give Go a copy of the inventory receipt, and had Go sign documents without informing him of his right against self-incrimination. The "Affidavit of Orderly Search" was not even executed under oath.

Unverified return of search warrant. The return of the search warrant was not verified under oath as required by the Rules of Court.

The Exclusionary Rule Applied

The Court emphasized that no presumption of regularity can justify an encroachment on constitutional rights. Citing the 1937 case of People v. Veloso, the Court stressed that search warrants must conform strictly to constitutional and statutory requirements, and no presumptions of regularity may be invoked to aid an officer justifying a search under a warrant.

Because the search was tainted with unreasonableness, the Court applied the exclusionary rule under Section 3(2), Article III of the Constitution, declaring the seized articles—including the alleged shabu—inadmissible in evidence. Without this evidence, the prosecution failed to prove Go's guilt beyond reasonable doubt.

Practical Takeaways

  • The exclusionary rule is a powerful remedy. Evidence obtained through an unreasonable search or seizure is inadmissible, regardless of its probative value.
  • Presumption of regularity is not automatic. Courts must carefully scrutinize police conduct when constitutional rights are at stake; the presumption cannot justify constitutional violations.
  • Witness requirements are mandatory. Searches must be conducted in the presence of the lawful occupant or a family member, or in their absence, two witnesses from the locality. Police cannot substitute their own choice of witnesses.
  • Knock-and-announce matters. Police must follow proper entry procedures unless there is a reasonable basis to believe prior notice would endanger the warrant's execution.
  • Detailed receipts are required. Police must provide a detailed inventory of seized items and give a copy to the person searched, and the return of the warrant must be verified under oath.
