Indonesia has switched the legal clock forward. On Friday, the country officially enforced the Indonesia new penal code, sweeping away colonial-era statutes that had shaped its justice system for more than 100 years, according to local media.

The change lands like a tectonic shift beneath the nation’s courts, signaling not just new rules, but a reimagined philosophy of justice.

A Historic Break From the Past

Coordinating Minister for Legal, Human Rights, Immigration, and Corrections Yusril Ihza Mahendra called the move a historic milestone, framing it as the dawn of a new chapter in Indonesian law.

The reform introduces a new national criminal code (KUHP) alongside an updated criminal procedures code (KUHAP), replacing outdated legislation enacted in 1918 and 1981.

From Punishment to Restoration

At the heart of the Indonesia new penal code is a fundamental shift: the justice system moves away from retribution and toward restorative justice. Rehabilitation and social reintegration now take precedence over sheer punishment.

Under the KUHP, courts can impose alternatives to prison, including community service, mediation, and medical rehabilitation for drug-related offenses. The goal is to ease chronic prison overcrowding while aligning the system with a more human rights–oriented approach—long championed by civil society groups pushing for drug law reform.

Changes to Criminal Offenses and Penalties

The new code revises or abolishes several offenses, including provisions on corruption, money laundering, and corporate criminal liability. These changes have not been without controversy.

Critics point to amended anti-corruption rules that reduce the minimum prison sentence from four years to two and lower fines to 10 million rupiah, down sharply from the previous 200 million rupiah minimum.

At the same time, the KUHP introduces new sanctions for intellectual property crimes, targeting trademark and branding violations, false IP ownership claims, and the leaking of trade secrets.

Modernizing Courtroom Procedures

The updated KUHAP focuses on how justice is delivered. It strengthens investigative, prosecutorial, and trial procedures while rolling out digital systems designed to make courts faster and more efficient—an attempt to bring the judiciary into the digital age.

A Law Years in the Making

Parliament approved the new penal code in 2022, after an earlier plan to implement it in 2019 was shelved. That delay followed student-led protests against controversial provisions, including articles criminalizing extra-marital sex and reviving penalties for insulting the president and state institutions.

Further opposition stemmed from concerns that the reforms weakened the Corruption Eradication Commission, an issue in a country frequently rocked by high-profile graft cases.

Corruption Still in the Spotlight

The timing of the new code coincides with renewed attention on corruption. In July 2024, a former minister was sentenced to 10 years in prison over graft charges. The United Nations has also urged Indonesia to adopt stronger anti-corruption and transparency measures in its palm oil industry.

Most recently, in March 2025, the attorney general opened investigations into a state-owned gas company amid allegations of embezzlement—underscoring why the evolution of Indonesia’s legal framework remains under intense scrutiny.
