On October 21, 2026, the six accused in Singapore's landmark Hyflux trial declined to argue there was "no case to answer" and told the court none of them will take the stand. A single joint expert witness will testify instead — as the prosecution's 54-day case gives way to the trial's decisive chapter.

On the morning of Wednesday, October 21, 2026, Principal District Judge Toh Han Li called on the six accused in the Hyflux criminal trial to open their defence. What the court heard was silence by design: lawyers for former chief executive Olivia Lum Ooi Lin, 65, and her five co-accused said none of the six will testify.
The defence also declined a "no case to answer" submission — the move in which the accused argue the prosecution's evidence is so thin that no defence is required. Instead, the six will jointly call a single expert witness and proceed to closing arguments.
Senior Counsel Davinder Singh, Lum's lead lawyer, told the court his client believes the prosecution "has not and will not be able to prove charges against her beyond reasonable doubt" — and will not waste the court's time on a threshold test "which ultimately may not matter." CNA reported from the courtroom; a second same-day report corroborated Singh's statement. The trial now shifts from a contest of evidence — 54 days, 22 witnesses — to a contest of legal argument.
The prosecution concluded its case in the trial that opened in August 2025: on September 29, 2026, after 54 days and 22 witnesses — former Hyflux staff who prepared corporate announcements, and bankers who negotiated Tuaspring's financing — it rested.
Lum faces the most charges: the prosecution proceeds on two charges under the Securities and Futures Act; four others were stood down. Ex-CFO Cho Wee Peng, 57, faces one charge of conniving in Hyflux's intentional failure to notify the securities exchange. The four former independent directors — Teo Kiang Kok, 70, Christopher Murugasu, 67, Gay Chee Cheong, 70, Lee Joo Hai, 70 — each face two charges: the omission in an April 2011 offer information statement, and alleged neglect of their directorial duties. A seventh person, Rajsekar Kuppuswami Mitta, was fined S$90,000 in 2025 after pleading guilty.
The allegation: Hyflux pitched Tuaspring as its second and largest desalination plant in Tuas, while omitting that cheap water sales to national agency PUB would be funded by a new business — selling electricity from a power plant it would build. The unsuccessful power-market foray contributed to Hyflux's collapse: about 34,000 investors holding perpetual securities and preference shares are owed S$900 million. If convicted, Lum faces up to seven years' jail, a S$250,000 fine, or both; Cho faces the same. Defence counsel: Davinder Singh Chambers (Lum), Rajah & Tann (Cho), Shook Lin & Bok (the directors).
The identity and content of the joint expert witness's testimony are undisclosed — whether it targets securities-law disclosure standards, the economics of the power plant, or both will shape the defence's attack on the claim that the omission misled the market.
We also do not know when the verdict comes, whether the four stood-down charges against Lum return, or whether a conviction would be appealed. And the investors' question stands: after judicial management, a 2021 winding-up order, and this trial, will the 34,000 investors owed S$900 million see any recovery?
Hyflux's collapse is routinely described as one of Singapore's largest corporate scandals — not for the sums alone, but for who bore them. The S$900 million was retail capital — perpetual securities and preference shares bought by ordinary investors who trusted a national champion. Hyflux won the Tuaspring tender with the lowest bid submitted: S$0.45 per cubic metre, at least 27% below competitors — a price at which, the prosecution alleged, the plant would operate at a loss, with the shortfall covered by selling electricity the company had never sold.
The backstory sharpens the point. Hyflux sought about S$527 million from a consortium of banks; six signed in-principle letters in October 2010. When they learned of the power-plant strategy that November, they "raised serious concerns"; by January 2011 they refused to lend on the indicated terms. Shut out of bank funding, Hyflux raised S$400 million in April 2011 from retail investors — the very offer documents at the centre of the charges. The professional lenders walked away from the risk, and retail investors were sold it.
A conviction would cement that material project economics must be disclosed; an acquittal would force a reckoning with whether the law can reach boardroom omissions at all. Either way, Singapore's reputation as a financial centre that protects its smallest investors is on trial alongside the six accused.
Why would six people fighting for their liberty refuse to speak? The answer is procedural. Testifying exposes the accused to cross-examination — and in a documentary case about 2011 disclosures, the prosecution's exhibits are the 2011 documents and the bankers' testimony. An accused on the stand can add little but can lose much. The defence's calculation, stated by Singh, is that the prosecution has not proved its case beyond reasonable doubt — a legal gap to exploit in submissions, not a factual one to fill by testimony.
Skipping it is the subtler choice. The submission is a gamble: if the judge rejects it, the defence has shown its hand early and the trial continues anyway. By declining to argue it, the defence signals it expects to win on the full record, not on a threshold test — and buys speed, with Lum wanting the case "decided as soon as possible."
The expert witness is the wild card. One joint expert for all six suggests the attack is doctrinal, not personal: on what "material information" means under the Securities and Futures Act, or on whether the electricity strategy genuinely determined Tuaspring's economics in 2011. If the expert reframes the power plant as reasonable commercial judgment rather than a hidden bet, "intentional failure to notify" starts to look like hindsight — and hindsight is not a crime.
Whatever the verdict, the trial is repricing directors' liability in Singapore. Four former independent directors — all in their late sixties and seventies — each face two charges for alleged neglect of their duties. The message to the region's boardrooms: independence is not insulation. A conviction would entrench as doctrine the caution already visible in independent-director recruitment since the charges were filed.
The second repricing is in retail structured products. The S$400 million 2011 preference-share issue was oversubscribed — investors queued for the yield. The trial forces the retail market to confront that preference shares and perpetuals are equity in a crisis, however bond-like the coupon looks. And the third is quiet geopolitics: Hyflux was a Singaporean national champion, and governments across Southeast Asia that copied the public-private infrastructure model are watching what happens when the champion stumbles — and who pays. See our Singapore factbook.
The trial now enters its defence phase: the joint expert testifies, the defence presents its case on the documents and the law, then come closing submissions — and Judge Toh Han Li's deliberation. No verdict date is set; in a case of this complexity the judgment could take months.
A conviction on either charge carries up to seven years' jail and a S$250,000 fine — and revives the four stood-down charges. An acquittal would be the prosecution's most consequential defeat in recent corporate-crime history, likely triggering a legislative re-examination of disclosure duties. For the 34,000 investors, neither outcome restores the S$900 million — but a conviction would answer the question asked for eight years: who was responsible?

The Western lens From the West, this hearing barely registers. Searches across the Western financial press turned up no coverage of the October 21 defence phase — the Reuters and Bloomberg wires have not picked up the story. The Western lens on Hyflux was fixed years ago: the collapse was filed as a case study in emerging-market project-finance hubris — a water company gambling its balance sheet on a merchant power plant.
The Eastern lens The East is where this story lives, and it is covering the trial with the granularity of a courtroom beat . CNA — Singapore's own broadcaster — reconstructs the hearing procedurally: the judge's call, the lawyers' statements, the penalty arithmetic. The Straits Times , the national paper of record, has anchored the prosecution's 54-day case: the 22 witnesses, the bankers' testimony, the allegation that Lum withheld the electricity-sales dependency.
The Global South lens From the Global South, the Hyflux trial is a mirror held up to every developing economy where corporate scandals end in silence . No dedicated Southern-outlet reporting on the October 21 hearing was found — a Singapore courtroom is not yet a Global South story. But the Southern reading writes itself: everywhere, the banks saw the risk first and the retail investors last , and the executives never saw a courtroom.
Founder and former CEO Olivia Lum Ooi Lin, 65; former CFO Cho Wee Peng, 57; and former independent directors Teo Kiang Kok, 70, Christopher Murugasu, 67, Gay Chee Cheong, 70, and Lee Joo Hai, 70. A seventh person, Rajsekar Kuppuswami Mitta, was fined S$90,000 in 2025 after pleading guilty. All six contest charges of failing to disclose material information about the Tuaspring project in 2011.
Their lawyers say the prosecution has not and will not prove the charges beyond reasonable doubt, so testimony is unnecessary. Testifying would expose them to cross-examination while adding little to a documentary case about 2011 disclosures. Instead they will call one joint expert witness and attack the case through legal submissions — a strategy that also speeds up the long-running trial.
Tuaspring was pitched as Hyflux's second and largest seawater desalination plant in Tuas, selling water cheaply to national agency PUB. Prosecutors allege Hyflux omitted that the project's profitability depended on a new business — selling electricity from a power plant it would build — information investors never received. Six banks refused to finance the power strategy in 2010–2011, citing merchant sale and operational risks.
The defence phase begins with the joint expert witness's testimony, followed by closing submissions from both sides. Principal District Judge Toh Han Li will then deliberate; no verdict date is set. If convicted, Lum and Cho face up to seven years' jail and a S$250,000 fine per charge, and the four stood-down charges against Lum could be reconsidered. The 34,000 investors owed S$900 million await the verdict.
