Claimant, Chas. T. Main International, Inc., filed a claim against respondent, Khuzestan Water & Power Authority, in the Iran-United States Claims Tribunal for amounts allegedly due under a contract for the provision of engineering and construction management services. Claimant contended that an exchange of documents and other conduct of the parties demonstrated the existence of a contractual relationship, despite respondent’s failure to sign a formal written agreement that had been drafted by claimant and allegedly approved by respondent. Respondent sought dismissal of the claim both on jurisdictional grounds and on the merits, contending that no contract existed since the respondent had never signed the formal agreement. In an interlocutory award, Chamber Two held: that respondent’s conduct, including the authorization and ratification of claimant’s services, demonstrated the existence of a contract, and that respondent’s refusal to pay for claimant’s services constituted a compensable breach of that contract. The Chamber further determined that the appointment of experts was necessary to ascertain the value of the services rendered.
