Jason Chua Aik Leng, 67, a Wah Loon Engineering director, was jailed 10 months and two weeks for abetting corruption in a DSO National Laboratories case.

He agreed to a plan relating to a $46 million project, with part of the contract price meant as a “token of appreciation” for a DSO staff member.

The scheme was exposed after a CPIB tip-off in 2023.

SINGAPORE - A company director who indirectly bribed a staff member of DSO National Laboratories was sentenced to 10 months and two weeks’ jail on Oct 16.

Jason Chua Aik Leng, 67, previously pleaded guilty to one charge of abetting the corrupt giving of gratification.

He was the senior executive director and shareholder of Wah Loon Engineering (WLE).

According to court documents, around 2018, Poh Beng San, an assistant manager of DSO’s facilities management team, told sub-contractor Alex Lee Yew Huat that DSO was looking for contractors to carry out works for one of its buildings.

DSO is Singapore’s largest defence research and development organisation. It serves public functions relating to national defence.

The court was told Poh had asked for a token of appreciation if the contractor secured the project.

Lee, a supervisor at fire protection company, Fire-Mech, contacted Chua saying he had inside information from someone in DSO who could help WLE win the project.

Chua was to then sub-contract the fire protection portion to Fire-Mech, and give about 1% of the contract price to that someone in DSO as a token of appreciation.

Chua agreed, and in January 2018, DSO extended tenders for building works to four contractors, of which three had WLE as a sub-contractor.

In September 2018, the contract was awarded to one of the three firms.

The project was valued at more than $46 million, with the mechanical and engineering sub-contract valued at $31.7 million.

Court documents said between October 2018 and February 2019, Lee gave Poh at least $150,000 in gratification with the help of a Malaysian director from another company.

The scheme came to light after the Corrupt Practices Investigation Bureau (CPIB) received a tip-off in February 2023 that Poh had allegedly been receiving gratification from contractors.

Chua was hauled in for questioning and admitted to his role.

The cases against Poh and Lee are ongoing.

During the sentencing hearing on Oct 16, District Judge Paul Chan had allowed in part Chua’s application for a deferment of sentence.

Chua had sought a deferment until February 2027, so he could celebrate his mother’s 100th birthday in November, take a family trip and celebrate the Lunar New Year.

The judge said deferment for a planned holiday and to celebrate the Lunar New Year were not justified.

However, he said the 100th birthday of Chua’s mother was justified, as it was an important and exceptional milestone that would not recur.

Chua is currently out on $100,000 bail and is expected to begin serving his sentence on Nov 23.

For corruption, he could have been jailed for up to five years and fined $100,000.

67岁的华隆工程公司董事蔡益良因在DSO国家实验室案件中教唆贪污而被判入狱10个月零两周。

他同意了一项与 4600 万美元项目相关的计划，其中一部分合同款项将作为对 DSO 员工的“感谢之礼”。

该计划在2023年经贪污调查局举报后被曝光。

新加坡——10月16日，一名公司董事因间接贿赂DSO国家实验室的一名工作人员而被判处10个月零两周的监禁。

67岁的蔡益伦（Jason Chua Aik Leng）此前已承认一项教唆行贿罪名。

他是华隆工程（WLE）的高级执行董事兼股东。

根据法庭文件，大约在 2018 年，DSO 设施管理团队的助理经理 Poh Beng San 告诉分包商 Alex Lee Yew Huat，DSO 正在寻找承包商为其一栋建筑物进行施工。

新加坡国防科技研究院（DSO）是新加坡最大的国防研究与发展机构，履行与国防相关的公共职能。

法庭获悉，Poh曾要求如果承包商能拿下这个项目，就给予一份感谢礼物。

消防公司 Fire-Mech 的主管 Lee 联系了 Chua，说他从 DSO 的某人那里得到了内部消息，可以帮助 WLE 赢得该项目。

蔡某随后将消防部分分包给 Fire-Mech 公司，并将合同价格的 1% 左右作为谢意支付给 DSO 公司的某位人士。

蔡先生同意了，2018 年 1 月，DSO 将建筑工程的招标范围扩大到四家承包商，其中三家承包商的分包商是 WLE。

2018 年 9 月，该合同授予了这三家公司中的一家。

该项目价值超过 4600 万美元，其中机械和工程分包合同价值 3170 万美元。

法庭文件显示，2018 年 10 月至 2019 年 2 月期间，李在另一家公司的一名马来西亚董事的帮助下，向 Poh 行贿至少 15 万美元。

2023年2月，贪污调查局（CPIB）接到举报，称Poh涉嫌收受承包商的贿赂，该计划才得以曝光。

蔡某被带去问话，并承认了自己的罪行。

对 Poh 和 Lee 的案件仍在审理中。

在 10 月 16 日的量刑听证会上，地方法官保罗·陈部分批准了蔡某的缓刑申请。

蔡先生曾申请将刑期延至 2027 年 2 月，以便他能在 11 月庆祝母亲的百岁生日，与家人一起旅行并庆祝农历新年。

法官表示，为庆祝计划好的假期和农历新年而推迟审判是不合理的。

然而，他表示，为蔡的母亲庆祝百岁生日是合理的，因为这是一个重要且特殊的里程碑，不会再有第二次。

蔡某目前以10万美元保释，预计将于11月23日开始服刑。

他因贪污罪可能被判处最高五年监禁并处罚款 10 万美元。
