US$740.3 Million ICSID Arbitration Award for Canadian Gold Mining Company
Petr was a key member of the Firm's international arbitration team which secured an award of US$740.3 million for Canadian gold mining company Gold Reserve Inc. against Venezuela, in an arbitration concerning Venezuela's deprivation of Gold Reserve's rights to develop the Brisas gold and copper mining project in southeastern Venezuela, one of the largest undeveloped gold and copper deposits in the world. Gold Reserve's claims were based on the Canada-Venezuela bilateral investment treaty, and the arbitration took place under the auspices of the World Bank's International Centre for Settlement of Investment Disputes (ICSID), pursuant to the rules of ICSID's Additional Facility. The unanimous award is one of the largest investment treaty awards to date, and highlights the Firm's world-leading experience in handling the most complex and significant international arbitrations.

Representing the Republic of Bulgaria in multiple investment treaty matters
Petr has represented the Republic of Bulgaria in an ICSID arbitration under the Energy Charter Treaty and a bilateral investment treaty concerning an oil refinery, in which Bulgaria defeated all claims (in excess of US$300 million); a pending ICSID arbitration under the Energy Charter Treaty and a bilateral investment treaty concerning Bulgaria’s electricity distribution and supply sectors; and an ICSID arbitration involving claims under a bilateral investment treaty relating to waste management services in the city of Sofia.

Favorable award for TECO Guatemala Holdings, LLC against Guatemala
Petr represented the claimant in an ICSID arbitration against Guatemala under the Dominican Republic-Central America-United States Free Trade Agreement (CAFTA-DR) relating to the claimant's investment in Guatemala's electricity distribution sector. The client was awarded in excess of US$30 million (including costs and interest).  In subsequent annulment proceedings, the ICSID ad hoc committee rejected Guatemala’s application for annulment of the award, upholding the award of damages to TECO, and granted TECO’s application for partial annulment of the award insofar as the original tribunal dismissed the remainder of TECO’s damages claim. TECO resubmitted the claim for the remaining portion of its damages to ICSID arbitration, which is pending.
