# Prevention of Crime Act (POCA): Preventive Detention for Organised Crime

> POCA (Act 297) permits preventive detention without trial for organised crime through the Prevention of Crime Board, not the courts — a regime distinct from SOSMA's focus on security offences.

A person can be named, investigated, and ultimately detained for two years without ever being charged in court — and that decision is made by a board, not a judge. That is the mechanism at the heart of the Prevention of Crime Act 1959 (POCA).

POCA, or the *Prevention of Crime Act 1959*, is referred to as **Act 297**. According to the Act's official reprint, it was revised in 1983 and that reprint came into force on 19 January 1984. This law is intended to prevent crime more effectively and to control criminals, members of secret societies and other undesirable persons. Unlike the ordinary criminal process, which turns on charges and proof in court, POCA operates through a distinct administrative regime.

## What distinguishes POCA from SOSMA?

Malaysia has several security laws that are often confused with one another. POCA and SOSMA (*Security Offences (Special Measures) Act 2012*) are frequently mentioned together, but the two target different things and operate differently.

| Aspect | POCA (Act 297) | SOSMA |
| --- | --- | --- |
| Main focus | Organised crime, secret societies | Specified security offences |
| Who orders detention | Prevention of Crime Board | Police (investigative detention), followed by charges in court |
| Investigative/administrative detention period | Up to 2 years by the Board, renewable | Up to 28 days by police (Section 4(5)) |
| Judicial review | Ouster clause declared invalid by the Federal Court (2022); review of the grounds of detention restored | Suspect brought to court to be charged after the investigation period |

According to the explanation by the law firm Low & Partners, Section 15A of POCA provides that there is no judicial review except in relation to compliance with procedural requirements; media reports, meanwhile, refer to Section 15B ousting the courts' jurisdiction over the Board's decisions. However, on 14 April 2022, Free Malaysia Today reported that the Federal Court ruled POCA's ouster clause invalid as inconsistent with Article 4(1) of the Federal Constitution, thereby restoring the courts' power to review the grounds of detention and not merely procedure. In short: POCA is a board-based organised-crime regime, while SOSMA is a security-offences regime.

## How does the detention process work?

The POCA process begins with arrest by the police and proceeds through several stages before reaching the Board. According to Low & Partners' explanation of the Act's text:

- **Within 24 hours** — the arrested person is brought before a Magistrate (Section 3(2)).
- **21 days** — the first remand in police custody by order of a Magistrate (Section 4(1)).
- **38 days** — the second remand upon the submission of a Public Prosecutor's statement (Section 4(2)).
- Overall, Human Rights Watch notes that the police may hold a suspect for up to about **59 days without judicial oversight** at the investigation stage.

After the investigation, the case is referred to an **Inquiry Officer**. According to the law firm Low & Partners' explanation, this officer is not a police officer and is appointed by the Minister (Section 8). The officer investigates and reports in writing to the Board on whether there are "reasonable grounds" to believe that a person should be registered (Section 9(1)).

## What is the Prevention of Crime Board?

The Prevention of Crime Board is the central body of this regime. Established under Section 7B, the Board is chaired by a legally qualified individual with at least 15 years of experience, assisted by a Deputy Chairman and several additional members, with a quorum of three.

Under **Part IVA (Section 19A)**, the Board may issue a detention order not exceeding **two years**, and may renew it for a further two-year period if satisfied that the detention is necessary in the interest of public order, public safety or the prevention of crime. As an alternative to detention, Section 15(2) allows the Board to impose restrictions such as restricted residence in a particular state or district, a bar on movement, an obligation to report at a police station, a curfew order, the fitting of an **electronic monitoring device**, and restrictions on internet access. According to Low & Partners, breaching these restrictions can carry a prison sentence of between two and ten years under Section 15(4).

## Why were the 2013/2014 amendments controversial?

POCA's administrative detention regime in its present form stems from a set of amendments passed by Parliament on **3 October 2013** and brought into force in 2014. These amendments restored detention without trial and introduced Part IVA, which permits detention orders by the Board.

There are differing views on these amendments, and this article presents both sides factually.

**The government and supporters' view.** The government defends POCA as a necessary tool for tackling organised crime, secret societies, and drug-trafficking and human-trafficking syndicates that are difficult to prosecute through ordinary trials because witnesses are unwilling to come forward.

**The critics' view.** The Malaysian Bar, through a statement dated 3 October 2013, raised several concerns. Its then-President, Christopher Leong, argued that the amendments permitted detention based on "belief or suspicion" rather than a proven offence. The Bar also characterised the Board as relying entirely on the Inquiry Officer's report without any independent power of investigation. Human Rights Watch, for its part, grouped POCA together with SOSMA and POTA as laws that, in its view, permit detention without trial and severe restrictions without judicial review.

Both of these positions remain part of the ongoing public debate over the balance between public security and individual rights in Malaysia.

## Court development: the 2022 ruling

On 14 April 2022, Free Malaysia Today reported that the Federal Court declared POCA's ouster clause — which had previously limited judicial inquiry into the grounds of detention — invalid as inconsistent with Article 4(1) of the Federal Constitution. According to the report, the ruling restored the courts' power to review, among other things, the validity of the Board's findings, the grounds of detention, and compliance with the principles of fundamental justice, and not merely procedural details. The report linked the ruling to the appeal of a detainee (reportedly named T. Dhinesh) whose preventive detention order was set aside. The exact section numbers and the official case citation still need to be verified against the text of the Act and the judgment reports.

## What next?

POCA remains a law in force in Malaysia and is among several administrative detention regimes frequently discussed in debates over the reform of security laws. The Federal Court's 2022 ruling on the ouster clause shows that the scope of judicial review over POCA detentions has changed, and readers are advised to refer to the latest text of the Act and the judgment reports for the current position. To understand the full framework, read the related articles on **SOSMA** and the **Prevention of Terrorism Act (POTA)**, which each target different categories of offences.
