Key Takeaways
  • • Court of Appeal upheld High Court ruling that Altana Wealth Ltd and Brevent breached confidence and misused trade secrets when launching their own distressed Venezuelan debt fund (ACOF) after joint venture with Illiquidx ended without fund launch.
  • • Judge Rajah established that "public domain" in non-disclosure agreements has its conventional confidentiality law meaning: information must be genuinely accessible to the public, not merely publicly available somewhere if searched for diligently.
  • • Collated information and investment rationale for a sanctions-compliant Venezuelan distressed debt fund strategy—though composed of publicly sourced data—qualified as confidential because the synthesis and strategic formulation were not in the public domain.
  • • Detailed investor presentation materials remained confidential despite marketing to selected potential investors, as they were not generally accessible to competitors or the broader investing public who did not receive direct distribution.
  • • Appeal dismissal confirms liability for breach of contract, misuse of confidential information, and trade secret infringement; individual defendants also faced personal liability findings.
Summary
Illiquidx Ltd pursued claims against Altana Wealth Ltd and Brevent following the breakdown of a joint venture agreement designed to establish a fund investing in distressed Venezuelan sovereign debt. Both parties had executed a non-disclosure agreement protecting broad categories of information. After the joint venture terminated without launching a fund, Altana proceeded independently to establish ACOF, its own distressed Venezuelan debt fund, prompting Illiquidx to allege misappropriation of confidential information and trade secrets.

The High Court, presided over by Mr Justice Rajah, examined the critical question of what constitutes "public domain" status under the NDA. The judge ruled that information need not be entirely obscure to retain confidentiality protections; rather, the standard reflects established confidentiality law principles. While individual data points regarding Venezuelan debt, sanctions compliance frameworks, and investment strategies existed in publicly accessible sources, the deliberate collation and synthesis of this information into a coherent investment thesis and fund rationale remained confidential. The strategic formulation—how to structure a sanctions-compliant vehicle for distressed Venezuelan debt investment—was not something the general public, competing investors, or uninvolved third parties could access or derive from scattered public sources.

Equally significant, detailed presentation materials distributed selectively to prospective investors retained confidential status. The fact that Altana had marketed to a chosen investor group did not place these materials into the public domain, as they remained inaccessible to competitors and investors outside the selected distribution list. The Court of Appeal's dismissal of Altana's appeal affirmed these findings, establishing precedent that commercial strategy documents and curated investment frameworks enjoy confidentiality protection even when constructed from publicly sourced components, provided their compilation and application remain restricted to authorized recipients.

The judgment confirms liability across multiple causes of action: breach of contract, misuse of confidential information, and infringement of trade secrets. Individual defendants also incurred personal liability, underscoring that confidentiality obligations extend beyond corporate entities to signatories and principals involved in their execution.
