G.R. Nos. L-37201-02, L-37424, L-38929. March 3, 1975.
CLEMENTE MAGTOTO, petitioner, vs. HON. MIGUEL M. MANGUERA, et al., respondents. (Consolidated with MAXIMO SIMEON, et al. vs. HON. ONOFRE A. VILLALUZ, et al. and PEOPLE vs. HON. ASAALI S. ISNANI, et al.)

FACTS

These consolidated petitions involved the admissibility of extra-judicial confessions obtained without the assistance of counsel prior to the effectivity of the 1973 Constitution. In the principal case, petitioner Clemente Magtoto sought to exclude his 1969 confession, arguing it was obtained in violation of his constitutional rights. The petitioners in the companion cases raised similar issues regarding confessions taken before January 17, 1973. The core factual dispute centered on whether the right to counsel during custodial investigation, expressly guaranteed for the first time under Section 20, Article IV of the 1973 Constitution, should apply retroactively to invalidate confessions obtained before its effectivity.
The respondents, including the People of the Philippines, contended that the governing law at the time the confessions were made was the 1935 Constitution and the Revised Penal Code, particularly Article 125. Under the prevailing jurisprudence, notably People v. Jose, a confession was admissible even if obtained without counsel, provided it was voluntary. The petitioners argued that the 1973 constitutional right was merely a codification of a pre-existing right implied from statutory and constitutional guarantees, and thus should apply retroactively.

ISSUE

Whether Section 20, Article IV of the 1973 Constitution, which mandates the assistance of counsel during custodial investigation, applies retroactively to confessions obtained before its effectivity on January 17, 1973.

RULING

The Supreme Court, through Justice Fernandez, ruled that the constitutional right to counsel during custodial investigation does NOT apply retroactively. The confessions obtained before January 17, 1973, without counsel, remain admissible if voluntarily given under the law then in force. The Court held that Section 20 of the 1973 Constitution granted this right for the first time in explicit textual form. Prior to this, the legal system, as construed in People v. Jose, admitted extra-judicial statements obtained during custodial interrogation without counsel, provided they were voluntary. The second paragraph of Article 125 of the Revised Penal Code, introduced by Republic Act 1083, was interpreted as merely granting a detained person the right to be informed of the cause of detention and to confer with counsel upon request. It did not impose an affirmative duty on the state to provide counsel during investigation.
The Court emphasized the principle that constitutional provisions affecting substantive rights are generally prospective, unless a contrary intent is clearly declared. No such retroactive intent was found in the 1973 Constitution or the proceedings of the Constitutional Convention. Applying the new rule retroactively would invalidate numerous convictions based on previously lawful evidence, causing judicial disruption and impeding the administration of justice. The ruling preserves the validity of judgments that became final under the old legal regime. The dissent, led by Justice Castro, argued for retroactivity to June 15, 1954 (the date of R.A. 1083), contending that the right was inherent in the 1935 Constitution’s due process and that the 1973 provision was merely declaratory. The majority, however, maintained its position, upholding the confessions in question as admissible under the law applicable at the time they were made.
