Confessions and Constitutional Rights: Safeguarding the Accused in Custodial Investigations

The rights of a person under custodial investigation — particularly the right to remain silent and the right to counsel — are among the most cherished protections in Philippine constitutional law. Yet, as the Supreme Court observed in People v. Salcedo (G.R. No. 100920, June 17, 1997), these rights continue to be violated by police investigators, leading to acquittals that the public often misunderstands. This case serves as a powerful reminder that even a confession reflecting the truth is inadmissible if obtained without counsel and without a valid waiver.

The Facts of the Case

In June 1988, Honorio Aparejado was killed in Masbate. Prosecution witness Edwin Cortes, the victim's brother-in-law, testified that eight armed men led by Noli Salcedo arrived at his house, ordered him and Aparejado to lie down, hogtied them, and brought them to a creek. There, Salcedo shot Aparejado twice and hacked him, while his companions also hacked the victim.

Three accused — Edison Banculo, Juanito Sual Jr., and Danilo Laurio — were implicated primarily through their extrajudicial confessions taken by police investigator Sgt. Jose Bajar. During cross-examination, the investigator admitted that none of the three were assisted by counsel when they signed their waivers or during the investigation itself.

The Constitutional Rights at Stake

The 1987 Constitution, under Section 12(1), Article III, guarantees that any person under investigation for an offense has the right to be informed of the right to remain silent and to have competent and independent counsel, preferably of one's own choice. If the person cannot afford counsel, one must be provided. These rights cannot be waived except in writing and in the presence of counsel.

Republic Act No. 7438 further strengthened these protections, defining the rights of persons arrested, detained, or under custodial investigation, and penalizing violations by public officers.

The Court's Ruling on Uncounselled Confessions

The Supreme Court emphasized that a voluntary extrajudicial confession, even if it reflects the truth, is inadmissible if given without the assistance of counsel and without a valid waiver. The Court quoted its earlier ruling in People v. Parel:

"The right to be informed carries with it the correlative obligation on the part of the investigator to explain, and contemplates effective communication which results in the subject understanding what is being conveyed."

The Court stressed that it is not enough for investigators to inform a person of the right to counsel. The person must also be asked whether he wants to avail of that right, and be told that he can hire counsel of his own choice or that one will be provided. Any waiver of the right to counsel must be made with the assistance of counsel — and that counsel must be a lawyer.

The Consequences of Constitutional Violations

Because the confessions of Banculo, Sual, and Laurio were taken without counsel, they were excluded from evidence. Without these statements, the remaining prosecution evidence was inadequate to prove their participation. The eyewitness admitted he did not know their identities at the time of the killing, only identifying them later in court after seeing them during custodial interrogation.

The Court acquitted the three on reasonable doubt, reiterating that the prosecution must prove guilt beyond reasonable doubt and that every circumstance favoring the accused's innocence must be considered.

However, Salcedo's conviction stood. He was positively and consistently identified by the eyewitness as the principal culprit who shot and hacked the victim. His defense of alibi — claiming he was working in Manila — failed because he could not name his employer or the construction firm, casting grave doubt on his credibility.

Practical Takeaways

• Uncounselled confessions are inadmissible. Any extrajudicial confession taken without the assistance of counsel, or where the waiver was not made in the presence of counsel, cannot be used as evidence against the accused.
• Mere information is not enough. Investigators must ensure the accused understands their rights, and must ask whether they wish to avail of counsel. The degree of explanation depends on the person's education and circumstances.
• Waivers must be in writing and with counsel. The right to remain silent and to counsel cannot be waived except in writing and in the presence of counsel.
• Alibi is a weak defense. Alibi cannot prevail over positive identification by a credible eyewitness, especially when the accused cannot substantiate the claim.
• The presumption of innocence matters. When the only evidence against an accused is an inadmissible confession, the prosecution fails to meet the burden of proof beyond reasonable doubt.
