After a gruelling 12-hour debate, the Prevention of Terrorism Act (Pota) was passed without amendment at 2.25am on Tuesday.

The Act is highly contentious because it allows detention without trial and cannot be subject to judicial review.

This has sparked fears that the law can be abused , much like the now defunct Internal Security Act (ISA).

Days after the new law was passed by the Lower House, it is the number of MPs who voted on the bill that has become the point of contention.

This is because the bill, involving nine block votes, was endorsed by the Dewan Rakyat with a vote of 79 to 60.

The number of BN lawmakers who voted in favour of the bill is lower than the total number of Pakatan Rakyat MPs in Parliament.

This has elicited much disgust from opposition supporters, who pointed out that their elected representatives did not fight to the bitter end and put their objections on record.

The outcry over this absenteeism by Pakatan MPs at this crucial vote has led many - including a significant number of Malaysiakini readers - to seek a complete list of those who did not vote.

While each Pakatan party keeps tabs of the attendance of its MPs through their respective parliamentary whips, the whips have been hesitant in providing Malaysiakini with a list of those who dug their heels and endured that long night.

Shortlisting process

Unlike many other countries, voting records in our Parliament are not readily available. However, they can be obtained from the parliament secretariat at a much later date.

For now, the list of possible absentees can be manually narrowed down by referring to the parliamentary Hansard.

The list at the bottom of this article contains the partial list of Pakatan MPs whose names did not appear on the Hansard during the Pota debate.

It must be stressed that this list by no means suggests that those named did not participate in the final vote, unless confirmed by the MP concerned.

However, attempts have been and are being made to contact those on the list to confirm whether they voted or not. Thus, the list will be updated as responses are received. Those who reply confirming attendance will be removed from the list.

It must also be noted that participating in a debate does not necessarily mean the MP stayed on until 2.25am, nor does silence during the debate mean the MP did not take part in the final vote.
