Our expertise encompasses both commercial and investment treaty arbitration. We regularly advise on a variety of arbitrations across numerous industries such as insurance, finance, automotive, pharmaceutical and TMT in connection with M&A, joint ventures, the termination of distribution agreements, and construction arbitration.
