I very much regret not to be able to join the majority decision of the Tribunal on the matter of admissibility of an ancillary claim as I do not share the conclusions of that decision nor the reasoning that led to it. The fundamental factual issue that needs to be taken into account is that the investment dispute brought before this Tribunal, irrespective of jurisdictional questions pending, arises from a single business decision by the Claimant so as to supply the Republic of Georgia with the gas that country needed. As noted in the decision, the mounting unpaid bills for this supply were the triggering factor of the dispute.
