Summary
In Wee Shuo Woon v HT S.R.L. ([2017] SGCA 23), the Court of Appeal upheld the High Court’s decision to expunge references to, and copies of, certain emails (“the Emails”) from an affidavit filed by the defendant, Wee, in related civil proceedings. The Emails were communications between HT and its lawyers concerning the very dispute that HT had commenced against Wee. Although the Emails had been leaked onto the internet following a cyberattack on HT’s systems, the courts held that they retained their protected character as privileged and confidential material, and that the court could restrain their use in the proceedings.
The Court of Appeal affirmed that the matter was not governed exclusively by the Evidence Act, and that equitable jurisdiction to restrain breach of confidence could be invoked to protect privileged and confidential documents even where they had become publicly accessible online. The court also emphasised that the balance between the policy imperatives of truth and legal professional privilege had already been struck in favour of preserving privilege, and that the defendant’s use of the Emails in the litigation was not justified merely because the information was obtainable from the public domain.
What Were the Facts of This Case?
HT is an Italian company specialising in security technology, supplying its products to law enforcement and intelligence agencies. Wee was employed by HT as a Security Specialist. On 20 January 2015, Wee tendered his resignation, giving the two-month notice required under his employment contract. His employment ended on 20 March 2015.
Two months later, on 20 May 2015, HT commenced Suit No 489 of 2015 (“S 489”) against Wee. HT alleged that Wee had breached his employment contract and duties owed to HT. Among other things, HT claimed that Wee had engaged in the business of a competitor, ReaQta Ltd (“ReaQta”), without HT’s knowledge or prior written consent. HT further alleged that Wee had represented himself as ReaQta’s “Asia Pacific representative” and “co-founder”. HT sought injunctive relief restraining Wee from seeking employment with competitors and from soliciting business from HT’s clients, as well as damages for breach of contract and fiduciary duties.
Wee filed his defence and counterclaim on 15 June 2015, denying the alleged breaches and counterclaiming for unpaid salary. HT denied the counterclaim and pleaded set-off. The litigation then became intertwined with a separate cyber incident: on or about 7 July 2015, HT’s computer systems were hacked by an unknown party. Approximately 500 gigabytes of data were extracted and uploaded to a website known as “WikiLeaks”. Among the uploaded materials were email communications between HT and its lawyers, Morgan Lewis Stamford LLC. These communications included legal advice and specific information and materials pertaining to S 489.
Critically, the Emails contained express reservations and warnings of privilege and confidentiality. One such reservation stated that the email may contain privileged and confidential information, that unintended recipients should delete copies and not circulate or reply, and that HT should be notified immediately. Wee later accessed WikiLeaks, located the Emails, and then relied on them in procedural applications in S 489. He filed Summons No 3852 of 2015 (“SUM 3852”) under O 18 r 19 of the Rules of Court to strike out the bulk of HT’s statement of claim on the basis of abuse of process, and also sought liberty to enter judgment on his counterclaim under O 14 r 5. In support, Wee filed an affidavit (“Wee’s Affidavit”) that made references to and exhibited copies of the Emails.
What Were the Key Legal Issues?
The Court of Appeal had to consider, first, whether the court’s power to expunge and restrain use of the Emails was governed exclusively by the Evidence Act, or whether other legal frameworks—particularly equitable principles relating to confidentiality—were available. This required the court to clarify the relationship between legal professional privilege, admissibility of evidence, and the law of confidence.
Second, the court had to address whether the Emails had “lost” their confidential character because they were uploaded to the internet and were generally accessible. This issue went to whether public availability on the internet necessarily defeats an action in confidence or prevents the court from granting an injunction or expunging offending material from pleadings and affidavits.
Third, the court considered the procedural and evidential dimension: whether, even if the Emails remained privileged and confidential, the court should exclude them from the litigation materials by expunging references and copies from the affidavit. Related to this was the timing point—whether the application to expunge could be granted before the Emails had been formally admitted into evidence.
How Did the Court Analyse the Issues?
The Court of Appeal began by focusing on the nature of the relief sought and the legal basis for it. HT sought (i) an order under O 41 r 6 of the Rules of Court to expunge references to the Emails in Wee’s affidavit and to expunge the copies exhibited therein, and (ii) an injunction to restrain Wee from further use of the Emails and other correspondence between HT and its solicitors. The judicial commissioner (“JC”) had granted the expunging relief, and Wee appealed.
On the first issue, the Court of Appeal agreed with the JC that the matter was not governed exclusively by the Evidence Act. The Evidence Act’s scope did not extend to affidavits presented to the court, and confidentiality could provide a separate legal basis for relief outside the law of evidence. This meant that HT’s application could be analysed through the equitable jurisdiction to restrain breach of confidence, rather than being confined to admissibility rules under the Evidence Act.
On the second issue, the Court of Appeal endorsed the JC’s careful conceptual distinctions. Legal professional privilege is concerned with protecting confidential communications between a client and lawyer for the purpose of obtaining legal advice or for litigation. Admissibility is a separate question: privileged documents may still be copied or even disclosed in some contexts without automatically becoming admissible. The law of confidence, meanwhile, addresses the protection of confidential information and the circumstances in which it would be unjust to allow its use or disclosure. The court’s analysis underscored that privilege does not automatically determine admissibility, and that confidentiality can justify restraining use even where the information is not “secret” in an absolute sense.
The Court of Appeal also accepted the JC’s propositions derived from earlier authorities: (a) the fact that a document is privileged does not preclude copies of the same from being admitted into evidence; (b) the court may restrict disclosure and use of privileged documents disclosed to third parties to protect their confidential character; (c) the court may restrain use by expunging offending portions of pleadings or affidavits; and (d) an application to expunge should be filed before the privileged documents are formally admitted into evidence. These propositions were important because they framed the court’s equitable power as a targeted remedy to prevent misuse of privileged and confidential material in the litigation process.
Turning to the “public domain” argument, the Court of Appeal held that public accessibility on the internet does not necessarily stifle an action in confidence. The relevant inquiry is whether, in all the circumstances, it would be just to require the party against whom confidentiality is asserted to treat the information as confidential. The court treated this as a contextual assessment rather than a categorical rule. In other words, the mere fact of online availability does not automatically extinguish confidentiality obligations or privilege protections.
Applying that approach to the facts, the Court of Appeal agreed with the JC’s reasoning that the Emails retained their protected character. Several factors were decisive. First, the Emails contained discussions between HT and its lawyers regarding S 489 and remained privileged against disclosure. Second, Wee was using the Emails against HT in the very proceedings for which they had been prepared, thereby undermining the rationale for privilege and confidentiality. Third, HT was the victim of a cybercrime, and Wee was well aware of that fact; the court considered it significant that the defendant obtained the Emails through a breach of security rather than through any legitimate disclosure process. Fourth, the Emails themselves contained express provisos of privilege and confidentiality, which put Wee on notice of their protected nature.
The Court of Appeal further addressed the policy tension between truth and privilege. Wee argued, in substance, that the Emails revealed wrongdoing by HT and that the court should allow their use to expose dishonesty and abuse of process. The JC had rejected this as a basis to refuse relief, reasoning that the balance between truth and privilege had already been struck in favour of preserving legal professional privilege. The Court of Appeal did not disturb that approach. It treated privilege as a foundational protection that cannot be eroded simply because the privileged material is relevant or because the party seeking to use it claims that it will advance the court’s search for truth.
Finally, the Court of Appeal considered the procedural posture. The JC had found that the Emails had not yet been used in S 489 in the sense of being formally admitted into evidence. They were referred to and exhibited in Wee’s affidavit, which was filed in support of SUM 3852 but had not yet been heard. This timing supported the grant of expunging relief as an equitable remedy to prevent breach of confidence before the material entered the evidential record.
What Was the Outcome?
The Court of Appeal dismissed Wee’s appeal and upheld the JC’s order expunging all references to the Emails in Wee’s affidavit and expunging the copies exhibited in that affidavit. Practically, this removed the privileged and confidential material from the pleadings and affidavit record in S 489, preventing Wee from relying on the Emails as part of his abuse of process application.
Although HT had also sought an injunction to restrain further use of the Emails, the procedural history indicated that the expunging relief was the focus of the appeal. The effect of the decision, however, was clear: the court would not permit the litigation process to be used to circumvent legal professional privilege and confidentiality merely because the information had been leaked online.
Why Does This Case Matter?
Wee Shuo Woon v HT S.R.L. is significant for practitioners because it confirms that legal professional privilege and confidentiality protections can survive a leak into the public domain. The decision rejects any simplistic “public availability” argument that would otherwise allow parties to weaponise privileged communications obtained through cybercrime or unauthorised disclosure. For litigators, this case provides a clear basis to seek expungement and restraint where privileged and confidential material is introduced into affidavits or pleadings.
From a doctrinal perspective, the case is also useful for clarifying the interplay between the Evidence Act and equitable confidentiality remedies. The Court of Appeal’s reasoning demonstrates that confidentiality-based relief is not confined to evidential admissibility questions. This is particularly relevant in Singapore practice, where affidavits and interlocutory applications often become the battleground for privilege disputes. The court’s emphasis on timing—applications should be brought before privileged material is formally admitted—highlights the need for prompt procedural action.
Finally, the case has practical implications for how parties should handle leaked documents. Even where a party believes the leaked material shows dishonesty or abuse by the opposing party, the court will still protect privilege and confidentiality. Practitioners should therefore anticipate that courts will prioritise the integrity of legal professional privilege and the confidentiality of lawyer-client communications over arguments grounded in relevance or perceived evidential value.
