Summary
ANB v ANC and another concerned a civil dispute arising from alleged surreptitious copying of data from a personal laptop used in the context of acrimonious divorce proceedings. Although the plaintiff’s substantive claims included conversion, trespass, and breach of confidence, the High Court hearing focused on interlocutory applications: whether an interim injunction should be set aside, whether the plaintiff should be allowed to cross-examine a computer expert and inspect his notebook computer, and whether portions of an affidavit should be struck out.
On 10 September 2014, Quentin Loh J set aside the interim injunction in part (while preserving an order requiring certain material not to be destroyed). The plaintiff’s application to cross-examine the defendants’ computer expert and inspect his notebook was dismissed. The defendants’ appeal against the assistant registrar’s refusal to strike out parts of the plaintiff’s fourth affidavit was also dismissed. No order as to costs was made at that stage.
What Were the Facts of This Case?
The plaintiff, ANB (referred to in the judgment as “H”), was embroiled in divorce proceedings in the Family Court with his wife, ANC (referred to as “W”). W was represented by a second defendant, AND, a law firm. The dispute in the High Court was not a direct trial of the divorce-related allegations; rather, it stemmed from a claim that W (and/or those acting for her) had obtained and used information copied from H’s personal laptop computer, the “Asus Notebook”.
H’s account was that, around 18 December 2012 while he was on holiday in Hong Kong with the couple’s two children, W returned to the matrimonial home, took away the Asus Notebook that had been left on the dining table, and later returned it to its original position. H asserted that he had left the laptop switched off or in sleep mode before leaving for Hong Kong. H’s central allegation was that the entire hard disc was copied, not merely the iPhone backup data. He further alleged that the copied material included sensitive information such as communications with his lawyers and account credentials (including user IDs and passwords).
H discovered the alleged copying after W filed and served affidavits in the Family Court. In one of W’s affidavits, H said he was shocked to see SMS and WhatsApp messages between himself and various persons, including family members and friends, as well as voice recordings of family conversations and events. H also believed that the material exhibited went beyond the iPhone backup he had created and stored on the Asus Notebook. H’s forensic narrative was supported by a computer expert, Mr Darren Cerasi (“Cerasi”), who found backed-up data from H’s iPhone on the Asus Notebook as at 12 December 2012. Cerasi also observed that one of the screws used to mount the hard drive was missing, and he inferred that the computer chassis had been dismantled and the hard disc removed to create a full clone. Cerasi further identified activity on 18 December 2012, when H was in Hong Kong.
W’s response denied hacking. She claimed she had been abruptly evicted from the matrimonial home on 26 September 2012, leaving behind clothes and belongings. She said she returned on 18 December 2012 to retrieve items, but found the door secured with a padlock. To gain entry, she enlisted a locksmith. W asserted that, as a joint owner, she had a right to enter. While inside, she noticed the Asus Notebook on the dining table. She claimed the laptop was in sleep mode and not password protected, and that she accessed it to check whether H had deleted web history, out of concern that the children might inadvertently access adult sites. She then became curious about H’s iPhone data.
W further alleged that she contacted a private investigator, Mr Dennis Lee, and asked him to make copies of files relevant to the divorce proceedings that would show H had made untruthful statements. W said Dennis Lee saved copies on an external hard drive and passed it to her the same day. W also stated that she returned the Asus Notebook to the matrimonial home and had no idea why the screw was missing. Thus, the factual dispute turned on whether W’s access was legitimate and limited, or whether there was unauthorised cloning and extraction of the hard disc while H was away.
What Were the Key Legal Issues?
The High Court’s decision was driven by interlocutory questions rather than the final determination of conversion, trespass, or breach of confidence. The first issue was whether the interim injunction—granted earlier to prohibit the defendants from using certain material in ongoing proceedings—should be set aside. This required the court to consider the applicable principles for granting and maintaining interlocutory injunctive relief, including the strength of the plaintiff’s case and the balance of convenience.
A second issue concerned evidence and forensic access. H sought to cross-examine W’s computer expert, Dennis Lee, and to inspect his notebook computer. The legal question was whether such procedural steps were appropriate at that stage, and whether the plaintiff had a sufficient basis to challenge the expert’s evidence and obtain inspection of the expert’s equipment.
A third issue arose from affidavit pleadings. W applied to strike out certain statutory declarations and parts of H’s fourth affidavit dated 22 August 2013. The assistant registrar refused to strike out those portions, and the defendants appealed that refusal in RA 75/2014. The High Court had to decide whether the impugned affidavit material should be struck out, which typically engages principles relating to relevance, admissibility, and whether the material is properly pleaded or is otherwise procedurally defective.
How Did the Court Analyse the Issues?
Although the substantive causes of action were conversion, trespass, and breach of confidence, the High Court’s analysis focused on the procedural and evidential posture of the case. The interim injunction had been granted earlier on 10 May 2013. At that earlier stage, counsel for H relied on authorities including Imerman v Tchenguiz and others [2011] 2 WLR 592 and X Pte Ltd and another v CDE [1992] 2 SLR(R) 575. Quentin Loh J recorded that he had expressed reservations about the applicability of those authorities, but granted the injunction because there would be full argument inter partes later.
When the defendants applied to set aside the injunction in Summons 2511/2013, the court had to revisit whether the plaintiff met the threshold for injunctive relief. The judgment indicates that the court ultimately set aside the injunction “save as to making an order requiring that certain material not be destroyed”. This demonstrates a pragmatic approach: while the court was not prepared to continue the broader prohibitory injunction, it recognised the risk that evidence could be lost or altered if material were destroyed. The tailored order preserved the integrity of the evidential record without maintaining the full restraint on use of material.
On the plaintiff’s Summons 5757/2013, H sought permission to cross-examine Dennis Lee and inspect his notebook computer. The court dismissed the application. While the truncated extract does not set out the full reasoning, the procedural context is clear: the plaintiff was challenging the defendants’ expert evidence and seeking access to the expert’s own computer equipment. Such requests often require careful consideration of relevance, proportionality, and whether the inspection is necessary for the fair disposal of the case. The dismissal suggests that the court was not satisfied that the requested steps were warranted at that interlocutory stage, or that the plaintiff had not established a sufficient evidential foundation to justify intrusive inspection of the expert’s materials.
As to RA 75/2014, the defendants appealed the assistant registrar’s refusal to strike out parts of H’s fourth affidavit. The High Court dismissed the appeal. Again, while the extract is incomplete, the outcome indicates that the court was not persuaded that the affidavit portions were so defective that striking out was necessary. In civil practice, striking out is a serious remedy, and courts generally require clear justification that the material is irrelevant, improperly pleaded, or otherwise incapable of being used at trial. The dismissal implies that the affidavit material remained within the permissible scope of the pleadings and evidence at that stage.
Finally, the judgment is notable for its procedural significance: the plaintiff was granted leave to appeal because there was a point of law involved—whether the court had discretion to exclude illegally or improperly obtained evidence in civil proceedings. This highlights that, beyond the immediate interlocutory relief, the case raised broader questions about the admissibility and exclusion of evidence obtained through alleged wrongdoing, and how civil courts should manage such evidence when it is sought to be used in ongoing proceedings.
What Was the Outcome?
On 10 September 2014, Quentin Loh J allowed the defendants’ application in Summons 2511/2013 in part. The interim injunction was set aside, but the court made an order requiring that certain material not be destroyed. This preserved evidence while removing the broader restraint that had prohibited use of certain material in ongoing proceedings.
The plaintiff’s Summons 5757/2013 was dismissed, meaning H was not granted leave to cross-examine the defendants’ computer expert or to inspect his notebook computer at that stage. The defendants’ RA 75/2014 was also dismissed. The court made no order as to costs.
Why Does This Case Matter?
ANB v ANC and another is important for practitioners because it sits at the intersection of civil injunction practice, evidence obtained through alleged unauthorised access, and the procedural management of expert evidence. Even though the decision is interlocutory, it demonstrates how courts may calibrate injunctive relief: rather than maintaining a sweeping prohibition, the court can tailor orders to address the real risk—here, the destruction of material—while allowing the litigation to proceed without unnecessary restraint.
More significantly, the case raises a point of law about whether civil courts have discretion to exclude illegally or improperly obtained evidence. That issue is of practical relevance in disputes where one party alleges that the other obtained documents, recordings, or digital data through wrongdoing. The High Court’s decision granting leave to appeal signals that the question was not merely factual; it had doctrinal implications for how Singapore civil courts should approach evidence tainted by illegality or impropriety.
For lawyers, the case also illustrates the importance of procedural strategy in complex digital evidence disputes. Applications to cross-examine experts and inspect equipment can be refused if the court considers them premature, disproportionate, or insufficiently grounded. Similarly, strike-out applications against affidavit content face a high threshold, and courts may prefer to let contested evidence be tested through the ordinary processes of litigation.
