Power of attorney – Challenge. The claimant had challenged a power of attorney made in favour of the first and second defendants. In those proceedings, he sought summary judgment and a worldwide injunction restraining the first defendant from acting on the power of attorney. The Chancery Division dismissed both applications. It was arguable that the claimant had not had standing to bring the claim nor had he joined all relevant parties to the proceedings. Consequently, the first defendant had a realistic prospect of success on the claim and the court accepted her undertaking not to use the power of attorney in the United Kingdom pending judgment or further order.
