all or part of the claims advanced by the Claimant in the Request; (b) a brief statement describing the nature and circumstances of any counterclaims advanced by the Respondent against the Claimant; (c) comment in response to any statements contained in the Request, as called for under Article 1.1(d), on matters relating to the conduct of the arbitration; (d) if the Arbitration Agreement calls for party nomination of arbitrators, the name, address, telephone, facsimile, telex and e-mail numbers (if known) of the Respondent's nominee; and (e) confirmation to the Registrar that copies of the Response (including all accompanying documents) have been or are being served simultaneously on all other parties to the arbitration by one or more means of service to be identified in such confirmation. 2.2 The Response (including all accompanying documents) should be submitted to the Registrar in two copies, or if the parties have agreed or the Respondent considers that three arbitrators should be appointed, in four copies. 2.3 Failure to send a Response shall not preclude the Respondent from denying any claim or from advancing a counterclaim in the arbitration. However, if the Arbitration Agreement calls for party nomination of arbitrators, failure to send a Response or to nominate an arbitrator within time or at all shall constitute an irrevocable waiver of that party's opportunity to nominate an arbitrator. 3.1 The functions of the LCIA Court under these Rules shall be performed in its name by the President or a Vice President of the LCIA Court
