Summary

The decision in [2026] SGHC 36 addresses the rigorous standards required to maintain a counterclaim in the face of a striking-out application under the Rules of Court 2021 ("ROC 2021"). The dispute arose from a failed "work-out" arrangement following the breach of a Share Purchase Agreement ("SPA"). The Claimant, Tahnoon Pasha, sought to recover outstanding tranches of a debt totaling millions of dollars. In response, the Defendants, Hill and Chionh, raised a counterclaim alleging that the Claimant had breached duties of "independence" and "good faith" contained within a subsequent Advisory Contract by the very act of commencing legal proceedings to recover the SPA debt.

The High Court, presided over by Low Siew Ling JC, was tasked with determining whether such a counterclaim disclosed a reasonable cause of action or was factually unsustainable. The core of the Defendants' argument rested on the novel proposition that an express contractual duty to act in "good faith" and "independently" within an advisory capacity could effectively paralyze a party’s pre-existing legal rights as a creditor under a separate, earlier agreement. The Defendants contended that the Claimant’s pursuit of the debt undermined the "spirit" of the Advisory Contract, which was intended to stabilize the company’s financial position.

Justice Low Siew Ling dismissed the appeal, affirming the Assistant Registrar’s decision to strike out the counterclaim and grant summary judgment in favor of the Claimant. The Court held that the Defendants’ interpretation of the Advisory Contract was legally and factually untenable. Crucially, the Court clarified that a general duty of good faith cannot be formulaically expanded to override clear, substantive rights held by a party under distinct contractual instruments. The judgment reinforces the principle that while the threshold for striking out is high, the Court will not permit "fanciful" or "legally hopeless" claims to proceed to trial, especially where they rely on a strained construction of contractual duties that contradict commercial common sense.

The decision is a significant contribution to Singapore’s jurisprudence on the "good faith" doctrine in commercial contracts. It emphasizes that such clauses must be interpreted within the specific context of the bargain and cannot be used as a "wild card" to import unexpressed restrictions on a party’s autonomy to enforce its legal entitlements. For practitioners, the case serves as a stern reminder of the necessity for precision in pleading and the limitations of using "novelty" as a shield against striking-out applications.

What Were the Facts of This Case?

The dispute centered on the fallout from a multi-million dollar share divestment in Cynopsis Solution Pte Ltd (the "Company"). The Claimant, Tahnoon Pasha, was a founding shareholder and director of the Company. On 3 February 2021, he entered into a Share Purchase Agreement (the "SPA") to sell his entire stake of 170,266 shares to the Defendants, Avere Mark Hill and Chionh Chye Kit, and a third party, Mr. Poh Ching Hong. The total consideration was fixed at $6,750,000, structured in four tranches: an initial $2,500,000 followed by three subsequent payments of $1,250,000, $1,500,000, and $1,500,000 due annually between 2021 and 2023.

While the first tranche was paid on 25 June 2021, the Buyers defaulted on all subsequent tranches. By mid-2023, the outstanding principal stood at $4,250,000. The Defendants cited the Company’s financial difficulties and a failed Series B funding round as reasons for their inability to pay. Between May and October 2023, the parties negotiated a "work-out" arrangement intended to provide the Defendants with more time to pay while involving Mr. Pasha in an advisory capacity to help stabilize the Company and facilitate an eventual exit or refinancing.

On 7 November 2023, this arrangement was formalized through two documents: a Side Letter and an Advisory Contract. The Side Letter explicitly acknowledged the Buyers' default and the total outstanding debt (including interest) of $4,250,000. It provided for a revised payment schedule, with the final deadline set for 26 June 2024. The Advisory Contract appointed Mr. Pasha as a "Strategic Advisor" to the Company. Crucially, Clause 5.4 of the Advisory Contract required Mr. Pasha to "act independently and in the best interests of the Company," and Clause 5.5 mandated that he "act in good faith in the performance of his duties."

Despite these new agreements, the Defendants failed to clear the debt by the June 2024 deadline. After further unsuccessful negotiations and a formal demand on 10 July 2025, Mr. Pasha commenced OC 591 on 28 July 2025. He sought the recovery of the unpaid tranches, which by then amounted to significant sums including accrued interest (e.g., $1,711,025.78 for the second tranche and $1,714,864.06 for the third tranche).

The Defendants did not deny the existence of the debt or the default. Instead, they filed a Counterclaim, alleging that Mr. Pasha’s act of suing them constituted a breach of his duties under the Advisory Contract. They argued that by commencing litigation, Mr. Pasha was no longer acting "independently" or in "good faith" for the benefit of the Company. They claimed that the litigation caused reputational damage to the Company, hindered its ability to raise funds, and distracted the Defendants from their management duties. They sought damages to be set off against the SPA debt. Mr. Pasha applied to strike out this counterclaim on the grounds that it was legally and factually unsustainable, leading to the AR’s decision which was the subject of this appeal.

What Were the Key Legal Issues?

The primary legal issue was whether the Defendants’ counterclaim met the threshold for striking out under Order 9 Rule 16 of the ROC 2021. This required the Court to evaluate the claim through two distinct lenses: legal sustainability and factual sustainability.

The specific issues to be determined were:

• Whether the counterclaim disclosed a reasonable cause of action: This involved determining if the alleged breaches of Clauses 5.4 and 5.5 of the Advisory Contract could, as a matter of law, be grounded in the act of a creditor enforcing a debt under a separate agreement. The Court had to decide if the duties of "independence" and "good faith" in an advisory context could extend to restricting a party's personal legal rights.
• The scope of the duty to "act independently": The Defendants argued for a broad interpretation where "independence" meant being free from personal interests that might conflict with the Company's welfare. The Court had to determine if this duty was limited to the performance of advisory tasks or if it governed the Claimant's conduct in his private capacity as a creditor.
• The scope of the express duty of "good faith": The Court examined whether the duty of good faith in the Advisory Contract required Mr. Pasha to "adhere to the spirit of the agreement" by refraining from any action (including litigation) that might harm the Company’s financial prospects.
• Whether the counterclaim was factually unsustainable: Even if a legal cause of action existed, the Court had to assess whether the Defendants’ pleaded facts had any "degree of conviction" or were "fanciful" and "factually impossible" based on the contemporaneous evidence.
• The "Novel Issue of Law" Exception: The Defendants argued that the interaction between advisory duties and creditor rights was a novel point of law that should only be decided at trial. The Court had to determine if this was a genuine novel issue or merely a "legally hopeless" argument dressed in the guise of novelty.

How Did the Court Analyse the Issues?

The Court began its analysis by restating the test for striking out under O 9 r 16(1) of the ROC 2021. Relying on Iskandar bin Rahmat v Attorney-General [2022] 2 SLR 1018, the Court noted that a claim is "legally unsustainable" if it is clear as a matter of law that the claimant will not be entitled to the remedy sought, even if all the facts alleged are proven. A claim is "factually unsustainable" if the allegations are "fanciful" or "rendered factually impossible" (citing Peloso, Matthew v Vikash Kumar [2024] 4 SLR 289).

Duty to Act Independently

The Court first addressed the alleged breach of the duty to "act independently" under Clause 5.4. The Defendants argued that this duty required Mr. Pasha to act without regard to his own interests. They relied on authorities such as Inche Noriah v Shaik Allie bin Omar [1929] AC 127 and Law Society of Singapore v Wan Hui Hong James [2013] 3 SLR 221. However, the Court distinguished these cases, noting they concerned the "independence" required of legal advisors to ensure a client’s actions were free from undue influence.

Justice Low Siew Ling found that in the context of the Advisory Contract, "independence" referred to the quality of the advice given—specifically, that Mr. Pasha should not be a "yes-man" to the Board but should provide objective, professional guidance. The Court held at [52]:

"I did not see how the duty to act independently in the performance of his duties as a Strategic Advisor could be construed as a duty to act independently of his own interests as a creditor of the Buyers under the SPA and the Side Letter."

Duty to Act in Good Faith

The analysis then turned to the express duty of "good faith" under Clause 5.5. The Defendants relied on HSBC Institutional Trust Services (Singapore) Ltd v Toshin Development Singapore Pte Ltd [2012] 4 SLR 738, arguing that good faith required "fidelity to the bargain." They contended that the "spirit" of the Advisory Contract was to save the Company, and suing the Defendants for the SPA debt was contrary to that spirit.

The Court rejected this expansive interpretation. It cited the UK Court of Appeal decision in Re Compound Photonics Group Ltd [2022] EWCA Civ 1371, where Snowden LJ cautioned against "formulaically" incorporating broad concepts into every good faith clause. The Court emphasized that the Advisory Contract and the SPA/Side Letter were distinct. The Advisory Contract governed Mr. Pasha’s role as a consultant; it did not, and could not, silently strip him of his rights as a creditor under the SPA. The Court noted at [63] that there was nothing in the Advisory Contract suggesting parties intended Mr. Pasha to "suspend his existing legal right to enforce an outstanding debt."

Factual Unsustainability

Even if the legal arguments had merit, the Court found the counterclaim factually unsustainable. The Defendants alleged that the litigation caused the Company’s downfall. However, the evidence showed the Company was already in severe financial distress long before the suit was filed. The Defendants’ own emails from 2023 admitted the Company was "running out of cash" and had failed to secure Series B funding.

The Court observed that the Defendants’ narrative—that the Company was on the verge of a "turnaround" which was only thwarted by the litigation—was unsupported by the record. The Court applied the "contextual meaning" approach from Yap Son On v Ding Pei Zhen [2017] 1 SLR 219, concluding that the Defendants’ interpretation of the facts was "fanciful."

The Novelty Argument

Finally, the Court addressed the "novel issue of law" argument. While acknowledging that novel issues should generally proceed to trial (citing CKR Contract Services Pte Ltd v Asplenium Land Pte Ltd [2020] 5 SLR 665), the Court held that this was not a license to maintain "hopeless" claims. The Defendants had failed to identify a genuine legal principle that was in a state of flux; rather, they were attempting to create a "novelty" by misapplying established principles of contract law to a clear-cut debt recovery scenario.

What Was the Outcome?

The High Court dismissed the Defendants’ appeal in its entirety. The Court affirmed the Assistant Registrar’s orders, which included:

• The striking out of the Defendants’ Counterclaim under O 9 r 16(1)(a) and (c) of the ROC 2021.
• The granting of summary judgment in favor of Mr. Pasha for the outstanding sums under the SPA and Side Letter.

The operative conclusion of the Court was stated at [78]:

"I therefore dismissed the Defendants’ appeal and affirmed the AR’s decision to strike out the Defendants’ counterclaim and grant summary judgment in favor of Mr Pasha."

Regarding the financial disposition, the Court upheld the Claimant's right to recover the principal sums of the unpaid tranches, which included $1,250,000 (Tranche 2), $1,500,000 (Tranche 3), and $1,500,000 (Tranche 4), along with the contractually agreed interest. The specific amounts claimed in the pleadings, such as $1,711,025.78 and $1,714,864.06, were affirmed as part of the summary judgment.

On the matter of costs, the Court followed the principle that costs follow the event. Having successfully defended the appeal and maintained the striking-out order, Mr. Pasha was entitled to costs. The Court fixed the costs of the appeal at $18,000 inclusive of disbursements, to be paid by the Defendants to Mr. Pasha. This was in addition to any costs awarded at the first instance before the Assistant Registrar.

The Court’s decision effectively ended the litigation at the interlocutory stage, preventing the Defendants from using the counterclaim as a means to delay the enforcement of a clear debt obligation. The judgment emphasized that the "interests of justice" under the ROC 2021 include the efficient disposal of cases that lack a sound legal or factual basis.

Why Does This Case Matter?

This case is of significant importance to commercial practitioners and litigators for several reasons, primarily regarding the limits of "good faith" clauses and the application of the ROC 2021 striking-out regime.

1. Clarification of "Good Faith" in Commercial Contracts: The judgment provides a necessary check on the tendency of litigants to invoke "good faith" as a nebulous, all-encompassing duty. By adopting the reasoning in Re Compound Photonics, the Singapore High Court has signaled that "good faith" is not a "roving commission" for the courts to rewrite the bargain. It confirms that an express duty of good faith in one contract (the Advisory Contract) does not automatically bleed into or restrict rights under a separate contract (the SPA), even if the parties are the same and the subject matter is related. This protects the "sanctity of contract" and ensures that specific debt-recovery rights are not inadvertently waived by entering into subsequent "work-out" or advisory arrangements.

2. The "Independence" of Advisors: The Court’s distinction between the "independence" required for fiduciary or legal advice and the "independence" required in a commercial advisory contract is a vital clarification. It prevents the misapplication of professional conduct standards (like those in Inche Noriah) to purely commercial consultancy roles. This is particularly relevant in the "start-up" and "turnaround" sectors where former founders often stay on as advisors while remaining creditors of the company.

3. Robust Application of O 9 r 16 ROC 2021: The case demonstrates the Court’s willingness to use its striking-out powers robustly under the new ROC 2021. While the "high threshold" remains, the judgment shows that the Court will scrutinize the "factual sustainability" of a claim by looking at the contemporaneous evidence. The Court’s refusal to be swayed by the "novelty" argument is a warning to practitioners: a claim must have a "degree of conviction" and cannot rely on a "fanciful" interpretation of the facts to survive a striking-out application.

4. Commercial Common Sense: The judgment is a victory for commercial common sense. It recognizes that a creditor who agrees to help a debtor "work out" their problems does not, by that act alone, forfeit the right to sue if the work-out fails. If the Defendants’ argument had succeeded, it would have created a dangerous precedent where any creditor providing advisory services to a struggling debtor would be effectively "locked out" of the courts, as any attempt to enforce the debt would be characterized as a breach of "good faith."

5. Impact on "Work-out" Negotiations: For transactional lawyers, this case highlights the importance of "no-waiver" and "reservation of rights" clauses in Side Letters and Advisory Contracts. It confirms that unless a party explicitly agrees to suspend their litigation rights, the Court will be slow to imply such a restriction from general "good faith" language.

Practice Pointers

• Drafting "Good Faith" Clauses: When including an express duty of good faith, practitioners should specify the scope of that duty. If it is intended to be limited to the performance of specific services, the drafting should explicitly state that it does not affect the parties' rights or remedies under other agreements.
• Separation of Roles: Where a party wears "two hats"—for example, as both a creditor and a strategic advisor—the contracts should clearly delineate these roles. A clause stating that "nothing in this agreement shall be construed as a waiver of the Advisor’s rights as a creditor under [Agreement X]" is highly recommended.
• Pleading Factual Sustainability: When facing a striking-out application on the ground of factual unsustainability, it is insufficient to merely assert that a "turnaround was possible." Litigants must be prepared to point to specific, contemporaneous evidence (financial statements, term sheets, correspondence) that gives the claim a "degree of conviction."
• The "Novelty" Shield: Do not rely on the "novelty" of a legal issue as a guarantee against striking out. The Court will look past the label of "novelty" to see if the underlying legal proposition is "hopeless" or "unarguable" in light of established contractual principles.
• Interplay of Multiple Agreements: In complex "work-out" scenarios involving Side Letters and new service contracts, ensure that the priority of agreements is clearly established. If the Side Letter acknowledges a debt, it is very difficult to argue that a contemporaneous Advisory Contract was intended to make that debt unenforceable.
• Reputational Damage Claims: If alleging that litigation caused "reputational damage" to a company, ensure there is a clear causal link. If the company was already in default and "running out of cash," the Court is likely to find that the litigation was a symptom, not the cause, of the company’s demise.
