Matters of significance in which Jill has been involved in include advising on / acting for the following:

  • The former majority shareholders of Yukos Oil Company before the Singapore International Commercial Court, in an application to enforce three arbitral awards rendered against the Russian Federation for breach of the Energy Charter Treaty. The awards total an aggregate value of around US$50 billion (with daily interest of more than US$6 million continuing to accrue). The Singapore action is part of a multi-jurisdictional enforcement effort involving the Netherlands, England, the United States of America and Luxembourg.
  • A subsidiary of a Mainboard-listed entity in urgent court proceedings against the beneficiary of a standby letter of credit and a local bank to restrain a call on a standby letter of credit issued for the amount of over US$126 million arising out of a contract to assemble a semi-submersible production platform in the north coast of Rio de Janeiro, Brazil. 
  • A subsidiary of a Mainboard-listed entity in SIAC arbitration proceedings against another Mainboard-listed entity for a claim of over S$34 million in respect of the latter’s breach of an agreement for the former to acquire and privatise the latter pursuant to a scheme of arrangement.   
  • A Cayman Islands hedge fund based in Hong Kong in SIAC arbitration proceedings in successfully rescinding a US$20 million investment in a blockchain / smart contract technology and financial products e-commerce and internet business as a result of a series of false and misleading representations made to it which induced the making of the investment, and in subsequent enforcement proceedings to recover the investment.
  • A leading multinational energy company and its subsidiary against a global energy company (and one of the largest state-owned enterprises in China) in the SICC to set aside an arbitral award valued at almost US$5.5 billion. The quantum of the dispute is possibly one of the highest sums in dispute for a single administered case by the SIAC to date. 
  • A family office and two individuals in complex High Court and Court of Appeal proceedings concerning investments in private equity funds and a hotel development valued at over US$127 million.
