Correcting Penalties in Drug Cases: Fair Application of Republic Act No. 7659

The Supreme Court has long held that a judgment imposing a penalty not authorized by law is void and can never become final and executory. This principle was applied in Rigor v. Superintendent, New Bilibid Prison (G.R. No. 156983, September 23, 2003), where the Court corrected an erroneous drug conviction penalty even though the accused had failed to appeal. The case clarifies how penalties under Republic Act No. 7659 should be computed for drug offenses involving less than 250 grams of prohibited drugs, and when a court may fix an illegal sentence on its own motion.

The Facts of the Case

Jose Victor Rigor y Danao was convicted by the Regional Trial Court of Mandaluyong City for illegal sale and possession of methamphetamine hydrochloride, or shabu. The trial court sentenced him in two separate criminal cases to:

• Six months and one day of arresto mayor maximum to four years, four months, and one day of prision correccional, plus a P5,000 fine in each case.

Rigor did not appeal, so the judgment became final. After serving one year and five months, he filed a petition for habeas corpus, asking the Supreme Court to reduce his penalty to six months and one day of prision correccional in each case so that he could be released.

The Issue

The central question was whether the Court could modify the penalties in a judgment that had already become final and executory. Rigor argued that Republic Act No. 7659 should be applied retroactively to his benefit, allowing his release.

The Court's Ruling

The Supreme Court denied the petition for habeas corpus, but it took the opportunity to correct the trial court's sentencing errors.

First, the Court noted a "palpable error" in the trial court's computation. The additional one day placed on the maximum period of arresto mayor was incorrect, because arresto mayor runs only from one month and one day to six months. Adding a day pushed the penalty into the range of prision correccional.

Second, the maximum penalty of four years, four months, and one day of prision correccional was also outside the range allowed by law. Under Republic Act No. 7659, which amended Republic Act No. 6425 (the Dangerous Drugs Act), the penalty for drug offenses involving less than 250 grams is prision correccional. Applying the Indeterminate Sentence Law, and with no aggravating or mitigating circumstances, the correct indeterminate sentence should have been:

• Minimum: six months of arresto mayor
• Maximum: the medium period of prision correccional, ranging from two years, four months, and one day to four years and two months

The correct penalty, therefore, should have been six months of arresto mayor as minimum to four years and two months of prision correccional as maximum—not the impossible figures the trial court imposed.

Why the Court Could Correct the Penalty

Ordinarily, a final and executory judgment cannot be modified. However, the Court cited People v. Gatward and People v. Barro, Sr. to explain an exception: a penalty that is not authorized by law is a nullity. It can never become final and executory, and the Court has the inherent power to correct it to conform with the law. This correction is neither a reduction nor an increase in favor of or against the accused—it simply makes the penalty lawful.

The Successive Service Rule

The Court also rejected Rigor's argument for immediate release. Under the Revised Penal Code, when an offender must serve two or more penalties that cannot be served simultaneously, they must be served successively—the second begins only after the first expires. Because Rigor's sentences could not run at the same time, he had to serve each up to its maximum term. This meant serving a total maximum period of eight years and four months before he could be eligible for release.

Practical Takeaways

• A void penalty can be corrected anytime. If a court imposes a penalty not authorized by law, that portion of the judgment is void and may be corrected even after the decision becomes final.
• Know the correct penalty ranges. For drug offenses involving less than 250 grams under Republic Act No. 7659, the penalty is prision correccional, and the Indeterminate Sentence Law applies to set the minimum and maximum terms.
• Do not rely on the trial court's arithmetic. Errors in computing penalty periods are common; always verify the statutory ranges under the Revised Penal Code and the applicable special law.
• Habeas corpus is not a substitute for appeal. A petition for habeas corpus cannot be used to challenge a final judgment or to seek a more favorable penalty; the proper remedy is a timely appeal.
• Multiple sentences are served successively. When penalties cannot be served simultaneously, each must be completed before the next begins.
