Summary
Global Yellow Pages Limited v Promedia Directories Pte Ltd and another suit [2013] SGHC 111 concerned two linked copyright infringement actions in which the plaintiff, Global Yellow Pages Limited (“GYP”), sought discovery of electronic documents. The appeals were not about the merits of copyright subsistence or infringement. Instead, they focused on the mechanics of e-discovery: whether the Assistant Registrar was correct to order that keyword searches be conducted on specified electronic devices, using keywords set out in the parties’ electronic discovery protocols.
In dismissing both Registrar’s Appeals (RA 421 and RA 422), Lee Seiu Kin J affirmed that the court may adapt discovery processes to the realities of electronic information. The judge accepted that it would be impractical to manually inspect large volumes of electronic data and that keyword-based searches, when properly framed, can be a workable and proportionate method to identify relevant documents. However, the court also made targeted variations to refine the scope of the searches to ensure relevance and avoid overbreadth.
What Were the Facts of This Case?
GYP is a Singapore-incorporated company listed on the Singapore Exchange. Its business includes publishing directories and providing classified directory advertising and related services. The dispute arose from GYP’s allegation that its copyright in directory compilations and related subscriber information had been infringed by two competitors: Promedia Directories Pte Ltd and Streetdirectory Pte Ltd.
GYP’s directories included both printed editions and an online directory known as the “Internet Yellow Pages”. The online directory was updated daily and could be searched through a search engine that returned results similar to those in the printed directories, subject to updates. GYP pleaded that it was the author and owner of copyright subsisting in multiple printed directory editions (for specified years) and in the online directory itself, each described as an intellectual creation arising from the selection and arrangement of contents. GYP also claimed copyright in subscriber information that it had verified, enhanced, arranged and classified based on information provided by telecommunications companies and reflected in GYP’s directory editions.
GYP’s infringement allegations were directed at Promedia’s and Streetdirectory’s directory products. For Promedia, GYP alleged infringement through reproduction or authorisation of reproduction, without licence or consent, in Promedia’s online directory, its printed directories (The Green Book), and The Green Book CD-ROM editions. For Streetdirectory, GYP alleged similar reproduction in Streetdirectory’s online directory. GYP sought to show infringement through (i) substantial similarities between listings in GYP’s directories and the defendants’ directories, and (ii) the presence of “Seeds” — fictitious subscriber listings planted by GYP in its own directories — which allegedly appeared in the defendants’ directories.
In response, Promedia and Streetdirectory denied infringement and challenged GYP’s claims to copyright subsistence and originality. Promedia also pleaded that it had independently created its own database over decades and that similarities in fact-based works like telephone directories were inevitable and did not amount to infringement. It further pleaded defences including fair dealing under s 35 of the Copyright Act (as referenced in the pleadings), public interest, laches/acquiescence/delay, and an “innocent infringer” position. Streetdirectory’s defence similarly denied infringement and emphasised that each entry in its website was a collection of factual information about business entities, with both parties allegedly relying on the same factual sources.
What Were the Key Legal Issues?
The principal legal issue in these appeals was procedural rather than substantive: whether the Assistant Registrar’s discovery order requiring keyword searches on electronic devices was appropriate. The appeals turned on the court’s approach to e-discovery, particularly the selection and use of keywords in search protocols to identify relevant documents.
More specifically, the court had to consider whether the keywords ordered for use in the searches were sufficiently connected to the issues in dispute and whether the search scope was proportionate. The protocols annexed to the discovery applications contained keywords to be used in searching specified devices, and the Assistant Registrar had ordered that certain keywords be used. Both defendants appealed the AR’s decision, and Streetdirectory additionally challenged one further keyword.
A secondary issue was the proper construction of the disputed keyword(s). The judge had to decide whether a purported keyword was in substance a valid search term or whether it was too vague or improperly framed to function as a keyword for e-discovery purposes.
How Did the Court Analyse the Issues?
Lee Seiu Kin J began by situating the dispute within the broader challenge of discovery in the digital age. The judge emphasised that while the law requires disclosure of relevant documents, exceptions exist where disclosure is not necessary for disposing fairly of the matter or for saving costs, or where documents are privileged. The court also recognised that common law discovery procedures were developed before the computer and internet era, and therefore must be adapted to address the practical difficulties of handling massive volumes of electronic information.
On that foundation, the judge addressed the rationale for keyword searches. The court accepted that it would be “enormously impractical” for a party to visually inspect each electronic document to determine whether it should be disclosed. Keyword searches, when properly designed, provide a practical mechanism to locate potentially relevant documents without requiring exhaustive manual review at the discovery stage. This approach reflects a proportionality mindset: discovery should be effective but not unduly burdensome.
In reviewing the Assistant Registrar’s orders, the judge focused on whether the search terms were aligned with the pleaded allegations and the likely content of relevant documents. The protocols included keywords such as “seed” or “seeds”, as well as other terms that could capture copying-related conduct (for example, “copy”, “follow”, and deletion-related terms). The inclusion of “seed(s)” was particularly significant because GYP’s case relied on the alleged planting of fictitious listings and their appearance in the defendants’ directories. If “seeds” were indeed used as a concept or label in internal communications, documents containing that term would be relevant to the copying narrative.
However, the judge also recognised that keyword searches must be scoped appropriately in time and context. In dismissing the appeals, Lee Seiu Kin J made two “minor variations” to the AR’s orders. First, the search for “seed” or “seeds” on the relevant custodians was limited to the period from 17 September 2010 to 6 November 2012, with liberty to apply to expand the period if GYP could prove that the expression entered into common vocabulary earlier. This variation reflects a concern that an unrestricted time range could generate excessive, irrelevant results and increase the discovery burden.
Second, the judge deleted a purported keyword described as “[name of each custodian/employee materially involved in creating, authoring and/or compiling the directories]” from the first column of the table pertaining to the keyword search. The judge’s reasoning, as indicated in the extract, was that the purported keyword was not properly construed as a usable search term. In e-discovery practice, a keyword must be sufficiently determinate to guide the search process. A placeholder-like phrase that depends on identifying names could be unworkable or ambiguous unless properly operationalised. By removing it, the court ensured that the protocol remained functional and legally coherent.
Overall, the court’s analysis demonstrates a balancing exercise: it endorsed the use of keyword searches as a legitimate e-discovery tool, while also ensuring that the search parameters were not overbroad or conceptually defective. The decision therefore provides guidance on how courts may supervise e-discovery protocols to maintain proportionality, relevance, and procedural fairness.
What Was the Outcome?
Lee Seiu Kin J dismissed both Registrar’s Appeals (RA 421 and RA 422). The practical effect was that the discovery orders requiring keyword searches on specified electronic devices remained in place, subject to the two minor variations made by the court.
The first variation narrowed the “seed(s)” keyword search to a defined time window (17 September 2010 to 6 November 2012), with liberty to apply for an earlier start date if GYP could justify it. The second variation removed an improperly framed purported keyword from the protocol, ensuring that the search terms were capable of being implemented as intended.
Why Does This Case Matter?
This decision is important for practitioners because it addresses, at an early procedural stage, how Singapore courts approach e-discovery in civil litigation. While the substantive dispute concerned copyright infringement, the judgment’s real contribution lies in its endorsement of technology-adapted discovery methods. The court acknowledged that discovery must be workable in the context of electronic data volumes and accessibility constraints, and that keyword searches can be a practical substitute for manual review.
For lawyers drafting discovery protocols, the case underscores two key points. First, keyword searches should be tied to the pleaded issues and the factual theory of the case. Here, the “seed(s)” concept was central to GYP’s allegation of copying, so it was rational to search for that term. Second, protocols must be proportionate and operationally clear. The time limitation imposed on the “seed(s)” search illustrates judicial willingness to constrain search scope to reduce noise and cost, while the deletion of the placeholder-like “name of each custodian/employee…” keyword illustrates the need for determinacy in search terms.
From a precedent perspective, the case supports a supervisory role for the court in refining e-discovery orders. It suggests that even where keyword-based discovery is accepted, courts will scrutinise whether the keywords and parameters are appropriate, implementable, and not unduly burdensome. Practitioners should therefore treat this judgment as guidance for both requesting and resisting e-discovery: the focus should be on relevance, proportionality, and clarity of the search protocol.
