In the face of the ambiguity in the documentary records, one of the means to break the gridlock and establish that the Issuer had issued the Additional Bonds would have been for the Claimant to bring the Issuer (which is a Singaporean company) into this action. Such a course would cohere with limb (e) of the Karaha Bodas requirements, set out at [20] above, ie, that any person whose interests might be affected by the declaration being sought should be before the court.
