s 2The Act applies to security offences, which are defined as the offences specified in the First Schedule (s 3).
s 3Defines key terms including 'security offences', 'Court' (meaning the Sessions Court), 'sensitive information', 'Minister', and 'protected witness' (s 3).

s 12States that all security offences shall be tried by the High Court (s 12).
s 13Bail is not granted to a person charged with a security offence (s 13(1)), except that a person under eighteen, a woman, or a sick or infirm person — other than for offences under Chapter VIA of the Penal Code or Act 770 — may be released on bail, subject to the Public Prosecutor's application for an electronic monitoring device (s 13(2)).

Worked examples

Example 1: Released early, with an electronic monitor

Facts. D is arrested for a security offence. After 24 hours a Superintendent of Police extends his detention by another seven days. When the seven days end he is released but is still needed for the investigation.

The law. Detention may be extended for not more than twenty-eight days in total (s 4(5)). A person released may have an electronic monitoring device attached if the Public Prosecutor applies to the Court, for a period not exceeding the remainder of the detention period allowed under s 4(5) (s 4(6)–(8)).

Outcome. This is the Act's own illustration to s 4: the Court may allow the device to be attached to D for up to twenty-one days.

Example 2: Bail for a Sick Accused

Facts. Siti, who is suffering from a serious illness, is charged with a security offence. She applies for bail.

The law. Bail is generally not granted for security offences, but a sick or infirm person may be released on bail subject to an application by the Public Prosecutor for an electronic monitoring device (s 13(1)-(2)).

Outcome. Siti may be released on bail if the Public Prosecutor applies for her to be attached with an electronic monitoring device (s 13(2)).

Example 3: Protected Witness Identity

Facts. Ravi is a protected witness in a security offence case. A journalist writes an article revealing Ravi's name and address.

The law. Any report on a protected witness shall not reveal the name, address, picture, or identifying evidence (s 16(1)). Preparing such a report is an offence (s 16(2)).

Outcome. The journalist commits an offence and is liable to imprisonment for up to five years and a fine not exceeding ten thousand ringgit (s 16(2)).

Examples are simplified illustrations with invented names; real cases turn on their own facts.

Questions & answers

Can I be arrested without a warrant for a security offence?

Yes, a police officer may arrest and detain any person without a warrant if they have reason to believe the person is involved in security offences (s 4(1)). You must be informed of the grounds of arrest as soon as may be (s 4(2)).

How long can I be detained for investigation?

You may be detained for 24 hours for investigation (s 4(4)). A police officer of or above the rank of Superintendent of Police may extend this for up to 28 days (s 4(5)).

Can I see a lawyer immediately after arrest?

You are allowed to consult a legal practitioner of your choice (s 5(1)(b)). However, a Superintendent of Police or above may delay this consultation for up to 48 hours if it would interfere with evidence, lead to harm, alert other suspects, or hinder property recovery (s 5(2)).

Will I be granted bail if charged with a security offence?

Generally no (s 13(1)). A person under eighteen, a woman, or a sick or infirm person may be released on bail, subject to the Public Prosecutor's application for an electronic monitoring device — but not where the charge is under Chapter VIA of the Penal Code (terrorism offences) or the Special Measures Against Terrorism in Foreign Countries Act 2015 (s 13(2)).

Can my identity be revealed if I am a protected witness?

No, any report on a protected witness shall not reveal your name, address, picture, or any evidence likely to lead to your identification (s 16(1)). Violating this is an offence (s 16(2)).

What happens if I am acquitted but the Public Prosecutor appeals?

The Public Prosecutor may apply for you to be remanded in prison pending the filing of a notice of appeal (s 30(1)-(2)). If the appeal is dismissed, they may apply for remand pending a further appeal to the Court of Appeal (s 30(5)-(6)). You shall be held until all appeals are disposed of (s 30(7)).
