Isabelle Michou received the award for the 2018 Most Important Decision in international arbitration at the Global Arbitration Review (GAR) Live annual awards, in recognition of last year’s final ICSID arbitral award in UP and CD Holding v Hungary. Isabelle led a team that recovered all claimed damages on behalf of UP and CD Holding, whose investment had been expropriated by Hungary in violation of an intra-EU Bilateral Investment Treaty (BIT). This was a landmark victory because it was the first time an ICSID arbitral tribunal confirmed that the controversial ruling of the European Court of Justice in Achmea v Slovakia (that arbitrators should decline jurisdiction over such intra-EU BIT disputes) did not apply to ICSID arbitration.
