International reinsurance companies – Ad hoc arbitration proceedings
We successfully represented a panel of reinsurance companies in an international ad hoc arbitration. The dispute arose out of a reinsurance treaty under the terms of which the reinsurers had reinsured a portfolio of risks underwritten by the cedent. The parties disagreed as to whether the reinsurance provided coverage for a certain loss that had occurred because of the market turmoil caused by the Covid-19 pandemic. The case involved highly complex legal and contractual questions requiring special expertise on reinsurance law and practice. The arbitral tribunal rejected the counterparty’s claims for reinsurance compensation against our clients in full. The amount in dispute was approximately EUR 34 million.
