Factual and Procedural Background
The case involves two main applications before the Court: an application by the Claimants to strike out parts of the Defendants' Counterclaim relating to the "surveillance claim," and an application by the Defendants for security for costs. The dispute arises from complex business and personal relationships centered around a hedge fund business known as the "IKOS Group," established circa 1991, which uses sophisticated quantitative investment management techniques, including proprietary software referred to as the "Code."
Key individuals include the Plaintiff Elena Ambrosiadou ("EA") and Martin Coward ("MC"), former spouses and founders of the IKOS Group, and two Defendants, Dr Ho and Dr Gover, former employees involved in the development and operation of the "Code." The Defendants' employment was terminated in December 2008.
Following termination, various proceedings were initiated, including claims by the Defendants in employment tribunals and proceedings by the Claimants against the Defendants in the High Court. The Defendants counterclaimed, alleging unlawful surveillance and harassment, among other claims.
The surveillance allegations involve covert operations allegedly authorized by the Claimants, including the use of an operative ("Laura Merts") who befriended the Defendants under false pretenses and had access to their private lives and information. The Defendants also allege other surveillance activities and unlawful entries, as well as hacking of email accounts.
The Claimants applied for summary judgment or striking out of parts of the Counterclaim, particularly the surveillance claims, while the Defendants sought security for costs due to concerns about the Claimants' ability to pay costs if ordered.
Legal Issues Presented
- Whether parts of the Defendants' Counterclaim concerning surveillance allegations should be struck out as disclosing no reasonable grounds or as an abuse of process.
- Whether the settlement of prior proceedings between the Defendants and one of the Claimants (EA) precludes the Defendants from pursuing claims against other Claimants or the IKOS Group entities as joint tortfeasors.
- The applicability and scope of the Protection from Harassment Act 1997 and Data Protection Act 1998 in relation to the alleged surveillance activities.
- Whether security for costs should be ordered against the Claimants, considering their financial position and the overlap between claims and counterclaims.
Arguments of the Parties
Claimants' Arguments
- The surveillance claims should be struck out on grounds including that the prior settlement with EA released the Claimants as joint tortfeasors and satisfied the Defendants' damage claims.
- It is an abuse of process to re-litigate the surveillance claims after settlement with EA.
- The other surveillance allegations lack sufficient pleading or evidence to sustain claims under the Protection from Harassment Act 1997.
- The Claimants contend that the Defendants have not provided particulars of loss and that certain claims lack merit.
- Regarding security for costs, the Claimants argue that guarantees provided by EA and a company called Wellently Ltd negate any reason to believe they cannot pay costs.
- They assert substantial overlap between their claims and the Defendants' counterclaims, arguing this affects the appropriateness and quantum of security for costs.
Defendants' Arguments
- The surveillance claims should not be struck out as the settlement with EA was personal and did not release other Claimants or the IKOS Group entities from liability.
- The Defendants assert that EA acted in a personal capacity in authorizing surveillance, or at least that this remains a factual issue requiring trial.
- The Defendants maintain that the surveillance was unlawful and amounts to harassment and misuse of private information under the relevant statutes.
- They argue that the surveillance claims raise serious issues of fact, credit, and credibility that cannot be resolved summarily.
- The Defendants contend that the Claimants are unable to pay costs and that the guarantees offered lack substance and enforceability, particularly given the complex corporate structures and offshore jurisdictions involved.
- They accept some overlap between claims and counterclaims but argue that a significant portion of the claims do not overlap, justifying an order for security for costs.

Court's Reasoning and Analysis
The Court began by examining the legal standards for striking out and summary judgment under CPR Rules 3.4 and 24.2, emphasizing the need for a realistic prospect of success and the overriding objective of dealing with cases justly.
Regarding the "Merts claims" (surveillance by operative Laura Merts), the Court noted the acceptance by the Claimants that surveillance was authorized but disputed the lawfulness. The Court found no basis at this procedural stage to strike out the claims, emphasizing the need for factual investigation, particularly on whether EA acted personally or in a corporate capacity, and whether the Claimants were joint tortfeasors.
The Court rejected the Claimants' arguments that the settlement with EA barred the Defendants from pursuing claims against other Claimants or the IKOS Group, relying on authority that a settlement with one tortfeasor does not automatically release others absent express agreement. The Court also rejected the abuse of process argument, noting that EA had denied personal liability and that the Defendants' claims raised distinct issues.
For other surveillance allegations (unlawful entries, following, photographing, hacking), the Court found that these claims, taken in context with the admitted surveillance, raised sufficiently arguable claims that should not be struck out. The Court recognized the developing nature of privacy law and that these issues required trial for resolution.
The Court allowed the Defendants to amend their Counterclaim to include unparticularised claims for specific monetary loss, given the Claimants' exclusive knowledge of the surveillance scope and potential damages.
On security for costs, the Court applied the threshold test requiring a reason to believe the Claimants could not pay costs. It found that Phaestos and Mindi were unable to pay due to lack of trading and assets, and that the guarantees offered by EA and Wellently Ltd were insufficient and of uncertain enforceability, particularly given the complex offshore structures and lack of financial disclosure.
The Court expressed doubt about CIF's financial position due to lack of disclosure and complex ownership, concluding there was reason to believe it could not meet a costs order.
In exercising discretion, the Court considered the overlap between claims and counterclaims, finding approximately 30% overlap, and adjusted the security amount accordingly.
The Court fixed security for costs at £2.5 million, allowing for phased provision and permission to apply if circumstances changed.
Holding and Implications
The Court DISMISSED the Claimants' applications to strike out and for summary judgment on the surveillance-related parts of the Defendants' Counterclaim, except that judgment was entered in favor of the Claimants regarding the equity share counterclaim which the Defendants abandoned.
The Court ordered the Claimants to provide security for costs in the sum of £2.5 million, reflecting the Court's view of the Claimants' financial position and the partial overlap of claims and counterclaims.
The decision ensures that the complex factual and legal issues concerning alleged unlawful surveillance and related claims will proceed to trial, preserving the Defendants' opportunity to present their case fully. No new legal precedent was established beyond the application of existing principles regarding abuse of process, joint tortfeasors, and security for costs.
