In a recent pre-recorded webinar hosted by LexisNexis, Maanas Jain, a senior associate and English-qualified barrister in the London office, discusses the landmark decision of the UK Supreme Court in Halliburton v. Chubb. The decision, which was handed down in November 2020, is now the leading English authority on apparent bias in circumstances of multiple arbitral appointments in interrelated cases. It also provides important guidance for the wider international arbitration community on arbitrator appointments and disclosures.

Maanas discusses the background to the appeal, the Court’s key findings, and the broader practical implications of the Court’s decision for London-seated arbitrations.

Three Crowns acted as counsel for the ICC Court as one of the interveners in the case.
