Criminal Investigations and Prosecution in Indonesia – Cosmos Legal Guide
Indonesia’s criminal law is primarily governed by the Indonesian Penal Code (Kitab Undang-Undang Hukum Pidana – KUHP) and the Criminal Procedure Code (Kitab Undang-Undang Hukum Acara Pidana – KUHAP). The country follows a mixed legal system, and the investigation and prosecution of crimes are regulated by central authorities.
1. Investigation Phase
Competent Authorities: Criminal investigations in Indonesia are conducted by the police (Polri) and the public prosecutor’s office (Kejaksaan). The police may detain suspects and initiate evidence-gathering procedures if there is reasonable suspicion of a crime.
Prosecutorial Oversight: The public prosecutor supervises investigations to ensure compliance with the law and decides whether to bring a case to court. The sufficiency and legality of evidence are critical at this stage.
Detention and Arrest: Suspects may be detained if reasonable suspicion or sufficient evidence exists. Detention periods are limited by law and can only be extended with a court order.
2. Evidence Collection
Witness Statements: Fundamental to the investigation process.
Physical and Digital Evidence: Documents, surveillance footage, digital data, and technical analyses are collected and added to the investigation file.
Expert Reports: In certain cases, technical or forensic expert opinions may serve as evidence.
3. Indictment and Filing of Charges
Once sufficient evidence is gathered, the prosecutor prepares an indictment and submits it to the court. The indictment outlines:
-
The crime alleged
-
The defendant’s purported actions
-
Applicable legal provisions
If evidence is insufficient, the case may be dismissed or a non-prosecution decision issued.
4. Criminal Trial
Courts: Criminal cases in Indonesia are heard by District Courts (Pengadilan Negeri) or High Courts (Pengadilan Tinggi) depending on the severity of the offense.
Right to Defense: Defendants are entitled to legal representation. Cosmos Legal provides professional legal representation, particularly safeguarding the rights of foreign nationals during investigations and trials.
Verdict: The court evaluates the prosecution’s claims, the defense’s arguments, and all evidence before delivering a judgment.
5. Types of Penalties
Common penalties under Indonesian criminal law include:
-
Imprisonment: Short- or long-term depending on the severity of the crime
-
Fines: Applied for minor offenses
-
Additional Sanctions: Disqualification from public office, professional restrictions, or deportation
6. Appeals and Cassation
Decisions can be appealed and brought before higher courts. Appellate and cassation courts review both procedural and substantive aspects to ensure compliance with the law.
