While in London, Shan was given carriage of the following cases as in-house counsel:

Investec Trust (Guernsey) Limited & Anor v Glenalla Properties Limited & Ors 

  • Commenced in Guernsey in 2010, these proceedings have set precedents on novel trust law issues, including in the judgment of the Judicial Committee of the Privy Council in [2018] UKPC 7. Shan was instrumental in securing the return of significant trust assets previously under the control of former trustees and court-appointed receivers for around 10 years. Shan also worked with Guernsey counsel and top silks at the English bar on a further appeal to the Judicial Committee of the Privy Council in 2020 on the question of the order of priorities to apply to competing claims against assets of an insolvent trust.

Robert Tchenguiz & Anor v Grant Thornton UK LLP & Ors

  • An English Commercial Court claim seeking c. £1 billion in damages for malicious prosecution, conspiracy and unlawful interference. The claim arose out of the defendants’ involvement in the highly publicised and ultimately unsuccessful investigation by the Serious Fraud Office of Robert Tchenguiz between 2009 and 2012. The case was ranked by The Lawyer as one of the top 20 cases in London of 2018. The litigation was ultimately settled on confidential terms a week into a 3 month trial.
