People vs. Figueroa

The Court held that extrajudicial admissions obtained during a custodial investigation conducted without counsel and without a valid written waiver are inadmissible in evidence against the declarant and cannot be used to justify a subsequent warrantless search. Furthermore, a warrantless search cannot be justified as a consented search when the property owner explicitly demanded a search warrant, nor as incidental to a lawful arrest when the arrest did not precede the search and the prior buy-bust operation had failed.

NBI agents conducted a buy-bust operation against Robert Figueroa based on an informant's tip. The operation failed to yield any drugs, but Figueroa fired a weapon and held hostages before surrendering to police. He was taken to the NBI headquarters and interrogated about the source of shabu without being informed of his constitutional rights or provided counsel. He allegedly admitted that his source was Beatrice Valerio. Agents then took Figueroa to Valerio's house, where Figueroa pointed out drug paraphernalia in the kitchen. The agents seized the items without a search warrant, claiming Valerio consented, although Valerio testified she asked for a warrant.

• The Buy-Bust Operation: NBI Agents Palencia and Soriano, acting on an informant's tip, set up a buy-bust against Figueroa. The informant met Figueroa with marked money. Figueroa sensed the agents' presence, fired at them, and held hostages for three hours before surrendering to Major Roberto Reyes. No drugs were found on Figueroa or in his house during a subsequent joint search.
• The Custodial Investigation: At the NBI headquarters, agents interrogated Figueroa about his shabu source without counsel. Figueroa allegedly admitted his source was Beatrice Valerio.
• The Search at Valerio's Residence: Agents took Figueroa to Valerio's house. Figueroa called ahead, and the gate was open upon arrival. Agents informed Valerio they were from a buy-bust and that Figueroa led them there. Valerio asked for a search warrant, but the agents had none. Figueroa, in handcuffs, went to the kitchen with Valerio and pointed out a pail containing liquid shabu and paraphernalia. Agents seized the items.
• Forensic Examination: Forensic Chemist Aranas confirmed the seized items contained methamphetamine hydrochloride and ephedrine. Figueroa tested positive for fluorescent powder from the buy-bust money; Valerio did not.

• Petitioner Figueroa argued that his constitutional rights during custodial investigation were violated because he was not apprised of his right to remain silent and to counsel, nor did he waive these rights in writing. Thus, his admission was inadmissible.
• Petitioner Figueroa maintained that the acquittal of his co-accused Valerio, who was charged under a conspiracy theory, should likewise absolve him, because in a conspiracy, the act of one is the act of all.

• Respondent OSG countered that warrantless searches are valid if consented to, and Valerio consented to the search of her house, thereby waiving her right against unreasonable search and seizure.
• Respondent OSG argued that Valerio's acquittal does not absolve Figueroa because he knew the exact location of the paraphernalia, independently establishing his guilt in manufacturing shabu.

• Procedural Issues: Whether the acquittal of a co-accused charged under a conspiracy theory mandates the acquittal of the other accused. Whether the extrajudicial admission of the accused during a counsel-less custodial investigation is admissible in evidence.
• Substantive Issues: Whether the warrantless search of the co-accused's residence was valid as a consented search or as a search incidental to a lawful arrest.

• Procedural: The Court ruled that the acquittal of a co-accused does not per se absolve the other accused. If conspiracy is not proven, conspirators are held individually liable for their own acts. However, Figueroa's criminal liability must be judged based on admissible evidence establishing his own acts beyond reasonable doubt. Regarding the custodial investigation, the Court ruled that the admission was inadmissible. Section 12(1), Article III of the Constitution requires that a person under investigation be informed of their rights to silence and counsel, and any waiver must be in writing and in the presence of counsel. Because Figueroa was interrogated without counsel and without a written waiver, his admission was inadmissible and could not be used against him or to justify the subsequent warrantless search.
• Substantive: The Court ruled that the warrantless search was invalid. It was not a valid consented search because Valerio explicitly demanded a search warrant, negating any actual intention to relinquish her right against the search. A valid waiver requires: (1) the right exists; (2) the person has knowledge of the right; and (3) an actual intention to relinquish the right. It was also not a valid search incidental to a lawful arrest because Valerio's arrest did not precede the search, and Figueroa was not lawfully arrested for drug offenses as the buy-bust operation failed. Consequently, the seized items were inadmissible as the fruit of an invalid search.

• Inadmissibility of Extrajudicial Admissions During Custodial Investigation — Any admission or confession obtained from a person under custodial investigation without informing them of their right to remain silent and to have competent and independent counsel, and without a written waiver made in the presence of counsel, is inadmissible in evidence against the declarant and against third persons, regardless of the truth or voluntariness of the statement.
• Valid Consented Search/Waiver of Right Against Unreasonable Search and Seizure — To constitute a valid waiver of the right against unreasonable search and seizure, it must appear that: (1) the right exists; (2) the person involved had knowledge, either actual or constructive, of the existence of such right; and (3) the said person had an actual intention to relinquish the right. An explicit demand for a search warrant negates the third element.

• "In other words, confessions and admissions in violation of Section 12 (1), Article III of the Constitution are inadmissible in evidence against the declarant and more so against third persons. This is so even if such statements are gospel truth and voluntarily given. Such statements are useless except as evidence against the very police authorities who violated the suspect's rights."
• "In case of consented searches or waiver of the constitutional guarantee against obtrusive searches, it is fundamental that to constitute a waiver, it must first appear that (1) the right exists; (2) that the person involved had knowledge, either actual or constructive, of the existence of such right; and (3) the said person had an actual intention to relinquish the right."

• People v. Chua Ho San — Cited as controlling precedent for the recognized exceptions to the requirement of a search warrant (including consented searches) and the elements of a valid waiver of the right against unreasonable search and seizure.
• People v. Burgos — Cited as the origin of the three-element test for a valid waiver of the right against unreasonable search and seizure.
• People v. Rivera — Cited for the rule that constitutional rights during custodial investigation attach from the moment the investigation starts.
• People v. Veronas; People v. Enriquez; People v. Cariquez — Cited for the principle that once a conspiracy is established, the act of one is the act of all, and conversely, if conspiracy is not proven, conspirators are held individually responsible.

• Section 12(1), Article III, 1987 Constitution — Guarantees the right of a person under investigation to remain silent and to have competent and independent counsel. The Court applied this provision to rule Figueroa's admission inadmissible because he was interrogated without counsel and did not waive his rights in writing.
• Section 14-A, Article III, Republic Act No. 6425 (as amended by R.A. No. 7659) — Penalizes the unauthorized manufacture of regulated drugs. The Court applied this to the charge but reversed the conviction due to inadmissible evidence.
• Section 5, Rule 113, Rules of Court — Enumerates the instances of lawful warrantless arrests (in flagrante delicto, hot pursuit, escaped prisoners). The Court found this inapplicable to validate the search, as the buy-bust failed and no lawful arrest for drugs preceded the search.
