Good Conduct Time Allowance Law: Confusing and Incoherent. Can We Have Clarity?

The Good Conduct Time Allowance Law is among the most progressive reforms in Philippine correctional history. Republic Act No. 10592 recognizes that imprisonment should not merely punish people. It should encourage discipline, education, rehabilitation, and personal transformation. During the first two years, a qualified person deprived of liberty may earn twenty days of sentence reduction for every month of good behavior. The allowance increases during the succeeding years of confinement.
A PDL may also earn an additional fifteen days monthly through studying, teaching, or mentoring. This benefit is called the Time Allowance for Study, Teaching, and Mentoring, or TASTM. Thus, a well-behaved PDL who actively participates in rehabilitation may earn substantial sentence reductions. The message of the law appears unmistakable: follow institutional rules, improve yourself, help others, and earn an earlier return to society. That is what genuine corrections should accomplish.
Except that the law produced a contradiction worthy of Philippine bureaucracy. Persons charged with heinous crimes are excluded from earning these allowances during preventive imprisonment. However, the Supreme Court has ruled that once they are convicted, even of heinous crimes, they may earn GCTA and TASTM while serving their sentences.
Let us repeat that slowly. While you are presumed innocent, you are disqualified; after you are declared guilty, you become qualified.
The Bureau of Jail Management and Penology, provincial jails, and the Bureau of Corrections deserve credit for implementing the law despite its confusing language. Jail and prison personnel document program participation, educational accomplishments, disciplinary records, and mentoring activities. They conduct orientations so that PDLs understand their rights and responsibilities. Many deserving PDLs have received earlier release because they behaved properly and participated meaningfully in rehabilitation. The law has also helped reduce overcrowding and the enormous public cost of prolonged incarceration.
That contribution should never be underestimated. Our detention facilities remain packed far beyond their intended capacity. Every unnecessary day inside jail requires additional food, medicine, security, utilities, and personnel. Overcrowding also spreads disease, intensifies violence, disrupts rehabilitation, and turns detention into slow human destruction. GCTA therefore serves correctional management, fiscal responsibility, institutional safety, and successful reintegration.
Yet the exclusion of people charged with heinous crimes during preventive imprisonment creates an indefensible injustice. Consider Juan dela Cruz, who remained in jail awaiting trial for six years, nine months, and four days. Throughout those years, he professed his innocence and followed every institutional rule. He organized paralegal services for fellow PDLs, taught literacy classes, mediated conflicts, and helped maintain an undermanned jail. He did everything the law supposedly wanted, except surrender his constitutional right to a full trial.
His case moved with the familiar speed of Philippine justice, which means it barely moved. Hearings were postponed, witnesses failed to appear, lawyers sought continuances, and court calendars overflowed. None of those delays were Juan’s fault. Nevertheless, because he was merely charged with a heinous crime, the jail could not grant GCTA and TASTM for those years. His actual detention would later be credited, but the good conduct and rehabilitation he demonstrated while presumed innocent would earn him nothing.
Suppose Juan is eventually sentenced to a maximum penalty of twenty years. Under the present interpretation, he begins earning GCTA and TASTM only after conviction. His years of teaching, mentoring, peacemaking, and faithful observance of jail rules disappear from the calculation. The State remembers every day of his confinement but forgets every day of his transformation. Apparently, the government keeps excellent records of suffering but develops sudden amnesia regarding rehabilitation.
Now consider Juan’s co-accused, who pleaded guilty after only one year. Because the co-accused was already convicted, he could begin earning GCTA and TASTM. Juan, meanwhile, insisted upon his innocence and exercised his right to trial. For exercising that constitutional right, he lost years of possible sentence reductions. The person who pleaded guilty early receives the correctional incentive, while the person who demanded that the prosecution prove its accusation receives nothing.
This arrangement does more than confuse people. It quietly punishes the exercise of constitutional rights. It pressures accused persons to plead guilty, especially when they are poor, detained, frightened, and unable to endure another decade of hearings. It also adds another layer to prolonged pretrial detention, where people already suffer punishment before conviction. Trial delay becomes the punishment, and GCTA disqualification becomes the additional punishment.
My previous work on pretrial justice has repeatedly emphasized this basic principle: detention should never become the default answer to every accusation. Low-risk accused persons should be considered for reduced bail, recognizance, supervised release, electronic or community monitoring, and other alternatives to detention. Those who must remain detained should still receive meaningful opportunities for rehabilitation. Risk, conduct, and actual behavior should matter more than the frightening label attached to the criminal charge.
A charge remains an allegation, not a conviction. Prosecutors may overcharge, witnesses may recant, evidence may collapse, and courts may eventually acquit. Yet the exclusion operates immediately, before guilt has been established. It treats the accusation as conclusive when denying benefits, then invokes the presumption of innocence when convenient. That is not rational correctional policy. That is legal gymnastics performed upon the backs of powerless people.
Congress should amend the law and clearly distinguish credit for preventive imprisonment from incentives earned through actual good conduct. The Supreme Court should also revisit the contradiction created by the present interpretation. At minimum, verified good behavior, studying, teaching, mentoring, and rehabilitation during pretrial detention should be credited upon conviction. Clear standards can prevent manipulation while protecting legitimate correctional incentives. Administrative safeguards are possible without erasing years of documented reform.
PDLs are too poor and powerless to make this contradiction a national controversy. They cannot hire lobbyists, purchase advertisements, or summon cameras whenever their rights disappear. But they remain human beings who follow rules, teach others, resolve conflicts, and struggle to change. If the State promises sentence reductions for rehabilitation, then it should honor that promise consistently. Good conduct should remain good conduct, whether demonstrated before or after conviction.
Can our legislators finally look into this contradiction? Can the Supreme Court provide a coherent and humane interpretation? Can the government stop penalizing people for delays they never caused? The GCTA Law was created to reward transformation and reduce needless incarceration. It should not become another punishment reserved for those still waiting for justice.
