Indonesian Advocates Upon the Threshold of the National Penal Code 2026: Readiness and Stratagem Amidst Legal Transfiguration

It has been ordained that the Republic of Indonesia shall formally bring into force the new National Penal Code (KUHP) on the 2nd of January in the year 2026, pursuant to Law Number 1 of 2023. This new Codex shall supersede the antiquated laws bequeathed by the Dutch colonial administration, which have held sway for more than a century. The Government hath declared this reformation a necessary act of legal decolonization, harmonizing criminal statutes with the socio-cultural values of the nation.

Yet, beneath the banner of reformation, there arises a spectre of concern regarding the potential criminalization of private life and the silencing of public expression under this new regime. As the vanguard of justice, advocates are summoned to prepare themselves for this fundamental transfiguration. The inquiry thus stands: to what extent are the advocates of Indonesia prepared to respond to the shift of 2026, and what stratagems must be forged to safeguard the rights of the accused within this new penal system?

I. New Paradigms and Controversial Articles of the National Codex

The new Penal Code heralds a shift in the very paradigm of Indonesian criminal jurisprudence.

• The Unification of Offenses: A most fundamental alteration is the vanishing of the distinction between “crimes” (misdrijven) and “violations” (overtredingen); both are now amalgamated into the singular classification of “criminal acts”. This affirms a recodification approach wherein various penal provisions are inscribed within a single national codex.
• The Living Law: Furthermore, the National Penal Code recognizes “the law that dwelleth within society” (living law) as a source of criminal law, provided it stands not in contradiction to the Pancasila and the 1945 Constitution. This signifies that customary norms may serve as the foundation for prosecution via Regional Regulations. This policy hath summoned controversy, for it bears the potential to breed legal uncertainty, given that the Code provides no definitive scope for this “living law”.

Matters of Morality and Expression A number of articles concerning morality are deemed controversial due to their divergence from the old statutes:

• Adultery and Cohabitation: These acts are now governed as complaint-based offenses (delik aduan). Article 415 expands the offense of adultery to include “Every person who engages in intercourse with a person who is not their husband or wife,” punishable by imprisonment of up to one year. Unlike the old Code, which sought only to protect the institution of marriage, the new Codex extends its reach to consensual relations between two unmarried adults. However, prosecution may only proceed upon a complaint lodged by a spouse, or if the perpetrators be unmarried by their parents or children.
• Unsanctified Cohabitation: Similarly, cohabitation without the bonds of marriage is regulated under Article 412, punishable by up to 6 months imprisonment upon complaint by a spouse, parent, or child. Critics argue this encroaches upon the sanctity of privacy.
• Offenses Against Dignity: Regarding freedom of expression, the Codex revives the prohibition against insulting the Head of State. Articles 240-241 criminalize insults against the President and Vice President, carrying a penalty of up to 3 years imprisonment. This has raised alarms regarding the restriction of legitimate criticism, fearing it may be misconstrued as insult.
• Public Order and Health: Provisions regarding demonstrations that “disturb public order” are deemed subjective and may induce a “chilling effect” on the populace. Furthermore, the Codex prohibits the unauthorized offering or demonstration of contraception to children (punishable by fine) and the offering of means to procure abortion (punishable by imprisonment or fine), provisions absent from the old laws.

II. The Professional and Technical Burden upon Advocates

In a scholarly gathering in Bali regarding the new Codex, practitioners highlighted the perils of implementing these new regulations, warning of potential criminalization not only of the citizenry but of law enforcement officers themselves should the regulations be misunderstood.

• The Imperative of Mastery: Advocates are duty-bound to master the philosophy and substance of the new Codex comprehensively before its enactment in 2026. With approximately 600 new articles in the Penal Code and the forthcoming Criminal Procedure Code, a massive undertaking of “upskilling” is required.
• A Shift in Spirit: The challenge lies not merely in comprehending the text, but in adapting to a new spirit of enforcement. The new Codex embodies modern principles such as alternative sentencing (community service, supervision), conditional sentences, and restorative justice. These principles shall fail if advocates remain tethered to the archaic mindset oriented solely towards incarceration. Advocates must be prepared to propose alternative sentencing options when such are more proportional than imprisonment.
• Procedural Discord: A grave concern remains that the revision of the Criminal Procedure Code (KUHAP) is not yet complete. If the substantive Penal Code is enforced whilst the procedural law remains antiquated, administrative chaos and conflict of norms may ensue. Advocates must be vigilant to ensure the rights of the accused such as early legal accompaniment—are honored despite this potential discord.

III. Implications for Legal Defense Strategy

The transmutation of criminal law necessitates a revision of defense strategies employed by the learned counsels.

• The Principle of Lex Mitior: The principle that the lighter provision must apply to the defendant shall be a crucial consideration during the transition. If an act occurs before 2026 but is judged thereafter, the advocate must argue for the provision most favorable to the client.
• Constitutional Advocacy: regarding controversial articles, such as insults against the President, the defense must employ a “constitutional advocacy” approach, arguing that the defendant’s words are criticism protected by freedom of expression. Reference to past Constitutional Court rulings should be utilized to convince the magistrate.
• Restorative and Meditative Arts: In cases of morality offenses (adultery/cohabitation), the strategy must pivot towards mediation, for these are complaint-based offenses. The advocate may facilitate dialogue between the client and the complainant (e.g., parents) to withdraw the complaint, thereby extinguishing the case.
• Alternative Sentencing: Counsel must be creative in leveraging the loopholes for alternative punishments. In the defense plea (pleidoi), advocates should argue for fines or community service rather than imprisonment for minor offenses, in alignment with the restorative spirit of the new law.

IV. Conclusion: Readiness is the Key to Sovereignty

The enactment of the National Penal Code 2026 presents a dual-faced reality for the profession.

• The Opportunity: It offers a foundation for advocates to play a more significant role in upholding substantive justice, protecting clients from arbitrariness, and encouraging humane sentencing.
• The Peril: Conversely, without preparation, advocates risk being trampled by their own ignorance of the new norms, leaving their clients’ rights in jeopardy.

Therefore, readiness is the paramount virtue. Advocates must immediately elevate their capabilities through rigorous training. They must possess a pocketbook comparing the old and new Codex and understand the transitional articles. Ultimately, the success of this legal reformation relies upon the actors within the system. If advocates are prepared in knowledge and integrity, the National Penal Code shall serve as a pillar of justice; if not, it risks becoming a mere instrument of repression. Let us greet this era with critical scrutiny and consummate professional readiness.
