Member of the Democratic Action PartyN8

Overall due diligence

Moderate

Enhanced due diligence required

Records show sustained national and state office plus a multi-stage prosecution under the Peaceful Assembly Act that ended without conviction, but every legal and biographical item rests on single-source reporting rather than verified documents, so enhanced due diligence is warranted to confirm.

Electoral resilience

High

Won five of seven contests listed, with large majorities at Ipoh Timor (34,000) and Kampar (11,801) and comfortable wins in Pasir Pinji; the 2022 Ketari win was narrow at 120 votes and the 1999 Malim Nawar contest was lost.

Political continuity

Stable

Continuously DAP across contests from 1999 to 2022, running within Barisan Alternatif, Pakatan Rakyat then Pakatan Harapan and shifting between Perak state, federal and Pahang state seats. A 2021 factional contest for the Perak DAP committee is a political fact, not misconduct.

Integrity signal

Review

Charged in 2013 under the Peaceful Assembly Act, given a discharge not amounting to acquittal in 2014 after a Court of Appeal ruling, reportedly recharged in 2016 and reportedly acquitted in 2018 when charges were withdrawn; no conviction appears on the records.

Financial / corporate

Open

Records contain no company-registry, GLC, foundation, asset-declaration, credit or procurement information; none of those checks are covered.

Litigation & legal matters

Peaceful Assembly Act 2012 charge over an assembly held without prior notice

Reportedly charged in 2013 with starting a peaceful assembly without prior notice; after a 2014 Court of Appeal ruling that the ten-day notice requirement was unconstitutional he applied to have the charges dismissed and was given a discharge not amounting to acquittal, was reportedly charged again for the same offence in 2016, and in 2018 the Sessions Court reportedly acquitted him after the attorney general's chambers withdrew the charges.N6 N5 N4 N3

Status: Concluded: discharge not amounting to acquittal (2014), recharge (2016), acquittal on withdrawal of charges (2018); all details from single-source reporting.

Key findings

Electoral record spans Perak state seats (1999, 2004, 2008), Ipoh Timor (2013), Kampar (2018) and Ketari (2022), all under DAP and its coalitions.E6 E5 E4 E3 E2 E1

Identified as a DAP assistant organising secretary who moved against the incumbent Perak DAP leadership in the 2021 state committee election.N2
A Peaceful Assembly Act prosecution against him ended in a discharge not amounting to acquittal and later an acquittal on withdrawal of charges.N6 N5 N4 N3

Red flags / areas of concern

The entire legal and biographical history rests on single-source encyclopaedia and database reporting that has not been checked against court or official records.N3 N4 N5 N6 N9 N10 N11
The 2022 Ketari win was by only 120 votes, indicating a thin current electoral base in that seat.E1
Unproven allegations of procedural irregularity and possible 'phantom voters' were raised in the 2021 Perak DAP committee election dispute.N1

Mitigating factors

The legal matter ended in acquittal in 2018 with charges withdrawn, following an earlier discharge not amounting to acquittal in 2014.N3 N5
No conviction, regulatory finding or adverse civil judgment is recorded against him.N3 N5 N6
The 'phantom voters' point was a claim made by his own camp to reporters about internal party registration, not a finding by any body.N1

Recommended next steps

1Obtain the Sessions Court and Court of Appeal cause lists and file searches for the Peaceful Assembly Act charge, the 2014 discharge, the 2016 recharge and the 2018 acquittal, including the AGC's withdrawal record.
2Run an SSM search on the person's name for directorships, shareholder stakes, charges and struck-off or dormant companies, and check for any GLC or state-linked appointments.
3Check MACC and Auditor-General/Public Accounts Committee publications and Dewan Rakyat and Pahang State Assembly Hansard for declarations of interest, committee roles and procurement-related questions.
4Confirm current party and legislative positions with the DAP national office and the Pahang State Assembly secretariat, including any state exco or committee appointments.
5Verify the electoral figures cited here against the Election Commission's official results portal for 1999, 2004, 2008, 2013, 2018 and 2022.
6Check asset-declaration filings, if any, with the relevant declaration portal and search Malaysian court registries for civil suits or bankruptcy proceedings.

Assessment

The public record is dominated by electoral results showing a long DAP parliamentary and state-assembly career across Perak, Pahang and a federal seat, with generally large majorities until a 120-vote win in Ketari in 2022. Beyond the ballots there is only single-source reporting: a Peaceful Assembly Act prosecution that ran from 2013 to an acquittal in 2018, and a 2021 factional contest for the Perak DAP committee. Nothing in the records supports any finding of wrongdoing, but corporate, financial, procurement and asset areas are entirely uncovered, so the picture is incomplete rather than clean.
