SINGAPORE - Amendments to the Criminal Law (Temporary Provisions) Act will take effect in the new year, when a list of criminal offences will be spelt out, said the Ministry of Home Affairs on Tuesday (Dec 11).
To be detailed in a new Fourth Schedule to the Act, these will include secret society activities, unlicensed moneylending, drug trafficking and those covered under the Organised Crime Act.
Previously, there was no such prescribed list.
The Act, introduced in 1955, allows the authorities to detain and supervise criminal suspects without trial, and the orders are reviewed yearly.
The ministry said it is used "judiciously" and only in cases where prosecution in court is not possible, like when witnesses are fearful or unwilling to testify.
It has been used against secret societies, drug syndicates and in serious crimes that threaten public safety, peace and good order.
In Tuesday's statement, the ministry said the changes would be effective from Jan 1.
It also said that the list in the Fourth schedule "will, in effect, restrict the minister's exercise of powers''.
The ministry added: " It also increases accountability on which types of activities could be the subject of a detention order."
Following the changes, the law will also be extended for another five years when the current Act expires on Oct 21, 2019.
This will be the 14th extension of the Act, which lapses every five years unless renewed by Parliament.
The Act will also carry a new clause which clarifies that the minister's decisions are final on matters such as whether a person has been associated with activities of criminal nature and whether it is necessary to detain him in the interests of public safety, peace and good order.
This clause had ruffled feathers during February's parliamentary debate, in which MPs had questioned whether the finality clause would limit judicial review.
Home Affairs Minister K. Shanmugam had clarified then that it would not because the courts can still review the minister's decisions based on the traditional tests of illegality, irrationality and procedural impropriety.
The ministry statement on Tuesday also said the changes would allow holistic rehabilitation for those under Police Supervision Orders, as the minister can prescribe new obligations, like counselling, to cater to individuals' needs and risks.
