Indonesia Enforces New Penal Code, Ending Decades of Colonial-Era Criminal Law

BY EMMANUEL OGBONNA

Indonesia on Friday began enforcing a sweeping new penal code, formally replacing a Dutch-era criminal law that had remained in force for more than eight decades and marking one of the most significant legal transformations since the country gained independence.

The move ends Indonesia’s reliance on a colonial framework that dated back to the pre-independence period and had long been criticized as outdated and disconnected from the nation’s social, cultural and religious realities. Since proclaiming independence in 1945, successive governments had pledged to overhaul the inherited criminal code, but political divisions and public opposition repeatedly delayed reform.

The new 345-page penal code, known locally as the KUHP, was approved by parliament in late 2022 and came into effect after a three-year transition period intended to give authorities, courts and the public time to prepare. Its enforcement represents a decisive shift in Indonesia’s legal landscape, introducing new offenses, restoring controversial provisions and reshaping sentencing practices across the country.

Efforts to revise the code stretched on for decades as lawmakers struggled to balance human rights concerns with religious norms and local traditions in the world’s most populous Muslim-majority nation. A previous attempt to pass a revised version in 2019 was shelved after nationwide protests erupted, with critics warning that several provisions threatened civil liberties and discriminated against minorities. Tens of thousands of people took to the streets, prompting then-President Joko Widodo to call for a delay.

Following further revisions, a parliamentary task force finalized the bill in November 2022. Lawmakers unanimously approved it the following month, with the government hailing the vote as a historic milestone in Indonesia’s post-independence legal development. International observers, including the United States, said at the time they were closely watching how the revised code would be implemented.

Deputy Law Minister Edward Hiariej has defended the reforms as a modernization of Indonesia’s criminal justice system, arguing that the new code reflects values long rooted in Indonesian society. He said the KUHP moves away from a purely punitive approach and instead emphasizes corrective, restorative and rehabilitative justice.

According to Hiariej, the revised framework prioritizes repairing harm, reintegrating offenders into society and expanding alternatives to imprisonment. Alongside the KUHP, the government is preparing a new criminal procedural law aimed at improving due process, addressing inefficiencies and strengthening human rights protections, a step officials describe as part of a broader overhaul of the justice system.

Despite those assurances, several provisions of the new code have drawn intense scrutiny from rights groups and legal experts. Among the most contentious measures are articles criminalizing sex outside marriage and cohabitation. Under the law, sex outside marriage can carry a prison sentence of up to one year, while cohabitation is punishable by up to six months. Authorities say such cases can only be pursued following a complaint from a spouse, parents or children, a safeguard they argue will prevent arbitrary enforcement, including against foreign visitors.

Human rights organizations remain unconvinced, warning that morality-based offenses risk invasive policing, selective enforcement and violations of privacy. Critics say the provisions could disproportionately affect women and marginalized communities, even if prosecutions are limited.

The code also revives bans on insulting the president or vice president, state institutions and the national ideology. Such cases must be initiated following a formal complaint by the president and can result in prison sentences of up to three years for acts deemed to attack the honor or dignity of state leaders. Government officials insist that strict guidelines have been issued to distinguish criminal insult from legitimate criticism, but civil liberties advocates argue the language remains vague and open to abuse.

Amnesty International Indonesia has described the KUHP as a serious setback for freedom of expression, warning that it could be used to suppress peaceful dissent and criticism of those in power. Similar concerns have been raised over the expansion of blasphemy provisions, which retain prison sentences of up to five years for deviations from the core teachings of Indonesia’s six officially recognized religions.

The revised code also maintains long-standing prohibitions related to communism, preserving penalties of up to 10 years for association with Marxist-Leninist organizations and four years for spreading communist ideology, reflecting sensitivities rooted in Indonesia’s violent anti-communist purges of the 1960s.

Not all aspects of the law have been met with opposition. Some civil society groups welcomed lawmakers’ decision to drop a proposed article that would have criminalized gay sex, a move seen as a rare concession following pressure from rights advocates. The change was viewed by some as a modest but meaningful relief for Indonesia’s LGBTQ community, which has faced growing social and legal pressures in recent years.

The KUHP also retains capital punishment, despite calls from domestic and international groups for its abolition. However, it introduces a new mechanism allowing death sentences to be reviewed after a 10-year probationary period. If a prisoner demonstrates good behavior during that time, the sentence may be commuted to life imprisonment or a fixed term of 20 years, a provision supporters describe as a step toward eventual abolition.

Abortion remains broadly prohibited under the new code, though existing exceptions have been formalized. Abortions are permitted in cases of life-threatening medical conditions or pregnancies resulting from rape, provided the procedure occurs before the fetus reaches 12 weeks.

Legal scholars say the new penal code signals a fundamental shift in sentencing philosophy. The Institute for Criminal Justice Reform has noted that the law expands the use of non-custodial penalties, such as community service and supervision, and gives judges greater discretion to tailor sentences based on circumstances. Advocates argue this could help reduce chronic prison overcrowding and improve outcomes for both victims and offenders.

Supporters of the reforms acknowledge that public attitudes toward punishment remain deeply influenced by retributive traditions but argue the new framework reflects a gradual move toward a more rehabilitative system. Whether the KUHP will ultimately deliver on its promise of modernization or deepen concerns over civil liberties will depend largely on how it is enforced in the years ahead.
