  • Supreme Court provides guidance 
on forum conveniens and piercing the corporate veil


    Macfarlanes LLP currently authors the Litigation & Dispute Resolution section of The In-House Lawyer magazine. For more information and articles from this author click here . This article considers the Supreme Court decision in VTB Capital plc v Nutritek International Corp & or s [2013]. Perhaps the most striking aspect of the case is that it casts doubt on the notion that the Court has the power to pierce the corporate veil. The Supreme Court also held that, even if the power to pierce the corporate veil does exist, it does not enable a claimant to hold parties that control a company jointly and severally liable under contracts entered into by that company.
