Summary
This High Court decision concerns a procedural dispute within an ongoing civil action: how keyword searches should be conducted in an electronic discovery (“e-discovery”) exercise. The plaintiffs, Breezeway Overseas Ltd and its director, sued UBS and related entities alleging misrepresentation and other wrongdoing in connection with leveraged bond transactions. After the Senior Assistant Registrar (SAR) ordered categories of electronically stored information to be searched and permitted certain keyword terms, the plaintiffs and the Bank disagreed on the use of some of the disputed keywords and on the scope of the parties’ ability to review search results for relevance, privilege, and confidentiality.
On appeal, Lee Seiu Kin J allowed the appeal in part. The court upheld most of the SAR’s keyword determinations, but adjusted the time period for the keyword “protest” to reflect the plaintiffs’ own case that the relevant protest occurred after February 2009. Importantly, the court also addressed the Bank’s concern that, under earlier authority, it would be prohibited from allowing the parties to review search results. The judge rejected the Bank’s restrictive interpretation and clarified that review of search results for relevance and related concerns is consistent with the discovery framework and the practical realities of e-discovery.
What Were the Facts of This Case?
The underlying substantive dispute involved the plaintiffs’ investment relationship with UBS. The first plaintiff, a company incorporated in the British Virgin Islands, was a long-time customer of the Bank. The second plaintiff, Mr Vasanmal Murli, was a director of the first plaintiff and the person who exercised effective and complete control over it. The plaintiffs alleged that, in or around 2008, they relied on representations made by the Bank’s employees and entered into loan arrangements with the Bank’s Hong Kong and Singapore branches to purchase a series of “leveraged bonds”.
The leveraged bonds included: (a) 6.625% ICICI Bank Bonds on 13 February 2008; (b) 7.335% Bank of Moscow Bonds on 14 February 2008; (c) 7.335% Bank of Moscow Bonds on 16 April 2008; (d) 6.609% VTB Cap Bonds on 15 April 2008; (e) 8.25% VTB Cap Bonds in July 2008; and (f) 5.75% Kaupthing Bank Bonds on 6 March 2008. The plaintiffs further alleged that the loans were represented to be fixed loans or fixed to maturity, meaning they could not be recalled prior to maturity. They claimed they were not told that collateral was required to secure the loans, nor were they informed which assets were allegedly collateralised.
According to the plaintiffs, in or around March 2009 the Bank issued margin calls requiring the plaintiffs to raise large sums within a short period, failing which the Bank threatened to liquidate the plaintiffs’ assets. The plaintiffs protested against the Bank’s decisions to reduce the quantum of the loans and to make the margin calls. The plaintiffs’ claims against the Bank included misrepresentation, breach of fiduciary duties, gross negligence, wilful misconduct, and breach of contract. These claims formed the backdrop for the discovery and e-discovery orders that were the subject of this appeal.
Within the e-discovery process, the parties were required to search electronically stored documents held by specific Bank employees. The second and third defendants, Susan Abraham and Vikrant Kanyal, were former employees who confirmed they did not have in their possession, custody or power any discoverable documents. The e-discovery application therefore focused on the Bank’s electronically stored materials, including emails in mailboxes, emails and documents in personal network profiles (P-Drive), and instant messaging records (“IMs”) of identified employees for defined time periods.
What Were the Key Legal Issues?
The appeal primarily concerned the proper conduct of keyword searches within e-discovery. The court had to determine whether the SAR was correct to allow or disallow certain disputed keyword search terms, and whether the time periods for those searches should be adjusted. The judge also had to consider the relevance and utility of keywords that the Bank argued were too generic or broad for the purposes of discovery.
A second, more legally significant issue concerned the entitlement of a party giving discovery to review the search results for relevance, privilege, and confidentiality. The Bank’s “sub-text” was that, on its interpretation of earlier authority, it would not be permitted to review the search results for relevance. The Bank feared that this would lead to over-inclusive disclosure, potentially requiring the plaintiffs to sift through irrelevant material, and also raising concerns about cost and efficiency.
Accordingly, the court had to reconcile the discovery obligation under Order 24 with the practical mechanics of e-discovery. The decision required the court to explain how keyword searches should be used to identify potentially relevant documents, and how the parties’ review rights fit within the legal framework for discovery, including the “necessary” requirement for discovery.
How Did the Court Analyse the Issues?
The court began by situating the dispute within the discovery framework under Order 24 of the Rules of Court. Discovery requires a party to disclose documents in its possession, custody or power that are relevant to the issues in dispute, subject to the requirement that discovery must be “necessary either for disposing fairly of the cause or matter or for saving costs”. The judge emphasised that e-discovery is an extension of this framework, not a departure from it. Keyword searches are a tool to operationalise relevance-based disclosure in a digital environment, where manual review of all potentially relevant documents is often impracticable.
On the keyword issue, the judge reviewed the SAR’s approach to relevance, specificity, and proportionality. The SAR had ordered searches for defined categories of documents (mailbox emails, P-Drive emails, P-Drive documents, and IMs) for two main time windows: February 2008 to August 2008, and February 2009 to June 2009 (with the second window applying to a slightly expanded set of employees). The SAR also required the Bank to conduct reasonable keyword searches and to attempt to agree on keywords. When agreement could not be reached, the Bank conducted preliminary searches to provide hit counts for the proposed keywords, which assisted the court in assessing whether the keywords were likely to be useful and not excessively broad.
At the first hearing, the plaintiffs proposed 30 keywords; the Bank agreed to seven and objected to 23. The seven agreed keywords included unique reference numbers (bank account numbers) and key witness identifiers such as “Murli”, “Vee”, “Vasanmal”, “Breezeway”, an email address, and two numeric identifiers. The Bank rejected the remaining 23 keywords as too generic and broad given that the employees were banking professionals in wealth management. The SAR later allowed ten of the disputed keywords and disallowed the remaining 13. The allowed keywords included “collateral”, “Fixed Loan”, a proximity search of “fixed” within ten words of “maturity”, “Protest”, “Bank of Moscow”, “Kaupthing”, “Kuznetski”, and “Republic of Venezuela”. The SAR also permitted “ICICI” and “VTB” but restricted those searches to specified repositories due to preliminary hit counts.
On appeal, the judge focused on nine of the ten keywords allowed by the SAR; the proximity search was excluded from the appeal because the Bank had deposed that its search engine could not perform proximity searches. The judge accepted that the core issue was whether the SAR’s keyword orders should be used to perform keyword searches on the documents. The Bank argued that the disputed keywords were of low relevance and that the searches were not necessary for fair disposal or for saving costs. The judge, however, treated the preliminary search results and the contextual relevance of the keywords as central to the assessment.
Crucially, the judge adjusted the SAR’s approach for the keyword “protest”. The plaintiffs had agreed that the alleged “protest” only arose on or after February 2009. The judge therefore allowed the appeal in part by restricting the keyword search for “protest” to the time period of February 2009 to June 2009. This modification reflects a careful calibration of relevance and temporal scope: even where a keyword is potentially relevant, the search should be confined to the period in which the underlying factual events occurred, thereby improving proportionality and reducing over-inclusiveness.
For the remaining keywords, the judge agreed with the SAR’s determinations. He accepted the SAR’s reasoning that some terms were directly tied to contested issues (for example, “collateral” given the dispute over whether loans were secured and what collateral was identified), while others were contextually relevant despite being common words (“Protest” in context, though with the corrected time window). The judge also endorsed the SAR’s view that certain bond names and country or issuer identifiers were sufficiently distinctive to the leveraged bond transactions alleged by the plaintiffs, thereby making them useful for locating relevant communications.
Turning to the second issue, the judge addressed the Bank’s interpretation of earlier authority, particularly the decision in Robin Duane Littau v Astrata (Asia Pacific) Pte Ltd [2011] SGHC 61. The Bank’s concern was that it would not be permitted to review search results for relevance, privilege, and confidentiality, and that this would force disclosure of over-inclusive material. The judge disagreed with the Bank’s restrictive reading. In doing so, he clarified that the discovery process is not designed to prevent the discovery party from performing meaningful review. Rather, the purpose of keyword searching is to identify potentially relevant documents, after which review mechanisms can be employed to ensure that only documents meeting the legal criteria for disclosure are produced.
In practical terms, the court’s reasoning supports a balanced e-discovery workflow: keyword searches serve as an initial filter, but the legal obligations under Order 24 still require relevance-based disclosure and the protection of privilege and confidentiality. The judge’s approach therefore aligns with the broader procedural objective of achieving both justice and efficiency. Over-inclusiveness is not eliminated by forbidding review; it is managed by allowing appropriate review and by tailoring search parameters (including time periods and repository scope) based on preliminary hit counts and contextual relevance.
What Was the Outcome?
The High Court allowed the appeal in part. The principal modification was that the keyword search for “protest” was restricted to February 2009 to June 2009, consistent with the plaintiffs’ concession regarding when the relevant protest occurred. For the other disputed keywords, the court agreed with the SAR’s orders and permitted the searches as determined below.
Beyond the keyword adjustments, the decision also clarified that the Bank’s concerns about an inability to review search results for relevance, privilege, and confidentiality were unfounded. This had the practical effect of confirming that the e-discovery process could incorporate review steps to manage relevance and protect legal interests, rather than requiring blind disclosure of all keyword hits.
Why Does This Case Matter?
Breezeway Overseas Ltd v UBS AG [2012] SGHC 170 is significant for practitioners because it provides early High Court guidance on how Singapore courts approach e-discovery disputes, particularly those involving keyword searches. The decision demonstrates that keyword selection is not a purely technical exercise; it is governed by the discovery principles in Order 24, including relevance and the “necessary” requirement for fair disposal or cost saving. Courts will scrutinise both the content of keywords and the scope of searches (including time periods and repositories) to ensure proportionality.
The case also matters for its clarification of review rights in e-discovery. The court rejected an overly restrictive interpretation that would prevent the discovery party from reviewing search results for relevance, privilege, and confidentiality. This is important because it affects how parties design their e-discovery protocols and how they allocate responsibilities for document review. For litigators, the decision supports the view that keyword searches are a starting point, not an end point, and that legal safeguards remain central to the discovery process.
Finally, the decision contributes to the developing body of Singapore jurisprudence on discovery in the digital age. Together with related cases cited in the judgment, it helps establish a framework for negotiating and litigating e-discovery protocols, including the use of preliminary searches, hit counts, and contextual relevance. Lawyers advising on discovery strategy can draw on the court’s reasoning to craft keyword lists that are sufficiently targeted, to justify search parameters, and to anticipate how courts may respond to concerns about over-inclusiveness and cost.
