Unlawful Search Evidence Obtained With Defective Warrant Inadmissible In Court

In People v. Mamaril (G.R. No. 147607, January 22, 2004), the Supreme Court reversed a drug conviction because the search warrant used by police was invalid. The Court held that the judge's failure to put the examination of the complainant and witnesses in writing—as required by the Constitution and the Rules of Court—rendered the warrant void. As a result, the marijuana seized during the search could not be used as evidence, and the accused was acquitted.

The Facts of the Case

On February 1, 1999, police officers implemented Search Warrant No. 99-51 against Benhur Mamaril at his parents' residence in Lingayen, Pangasinan. The warrant authorized a search for marijuana. During the search, officers seized over 1.8 kilograms of marijuana in various forms, including sachets and bricks.

Mamaril was charged with illegal possession of prohibited drugs under Section 8 of Republic Act No. 6425, as amended. The Regional Trial Court convicted him and sentenced him to reclusion perpetua and a fine of P500,000.

The Issue: Was the Search Warrant Valid?

On appeal, Mamaril argued that the search warrant was illegally issued. He pointed out that the records of the trial court did not contain any transcript of stenographic notes showing that the issuing judge personally examined the complainant and his witnesses in the form of searching questions and answers.

The Branch Clerk of Court testified that despite his best efforts, the transcript could not be located. The records contained only the application for the search warrant and the supporting affidavits of the witnesses—nothing more.

The Ruling: Strict Compliance Required

The Supreme Court ruled in Mamaril's favor. The Court cited Article III, Section 2 of the 1987 Constitution, which requires that a search warrant issue only upon probable cause determined personally by the judge after examination under oath of the complainant and witnesses. This is implemented by Section 5, Rule 126 of the Rules of Court, which states that the judge must conduct this examination in the form of searching questions and answers, in writing and under oath, and attach the sworn statements to the record.

The Court emphasized that mere affidavits are not enough. Citing Mata v. Bayona, it explained that the written deposition is necessary so the judge can properly determine probable cause and so the person giving it can be held liable for perjury if the declarations turn out to be false.

Because the prosecution failed to prove that the judge reduced his examination to writing, the search warrant was declared null and void.

No Waiver by Silence

The Solicitor General argued that Mamaril waived his right to question the search because he did not protest when the police arrived. The Court rejected this argument.

Citing People v. Burgos, the Court held that a peaceful submission to a search is not consent. To constitute a waiver, three elements must appear: (1) the right exists, (2) the person had knowledge of the right, and (3) the person had an actual intention to relinquish it. Silence in the face of a search warrant is merely a demonstration of regard for the supremacy of the law—not a waiver.

The Court also noted that Mamaril seasonably objected to the admissibility of the evidence during trial, after the prosecution formally offered its exhibits.

The Exclusionary Rule Applied

The Court applied the exclusionary rule under Article III, Section 3(2) of the Constitution: any evidence obtained in violation of the right against unreasonable searches and seizures is inadmissible for any purpose in any proceeding.

The Court declared that no matter how incriminating the articles taken from the appellant may be, their seizure cannot validate an invalid warrant. Without the illegally obtained evidence, there was no basis to sustain the conviction. Mamaril was acquitted and ordered released.

Practical Takeaways

• Judges must follow the letter of the law when issuing search warrants. The examination of the complainant and witnesses must be in writing, under oath, and in the form of searching questions and answers. The written record must be attached to the case file.
• A defective warrant voids the search. If the judge fails to comply with the constitutional and statutory requirements, the warrant is null and void, and the search conducted under it is illegal.
• The exclusionary rule is strict. Evidence seized through an invalid warrant cannot be used in court, no matter how incriminating it is.
• Silence is not consent. A person who peacefully submits to a search does not waive the right to question its legality later.
• Objections must be timely. A person challenging a search should raise the objection at the proper stage of the proceedings, such as when the prosecution offers its evidence.
