On 27 May 2015, the 160-page reserved judgement of the Singapore Court of Appeal (“CA”) was handed down in Persero 2 - PT Perusahaan Gas Negara (Persero) TBK (“PGN”) v CRW Joint Operation (“CRW”)[1]. It will be regarded a triumph for contractors wishing to enforce DAB decisions. The CA ruled that the interim award issued by the arbitral tribunal ordering enforcement of the DAB’s decision should stand. Using the concept of an “inherent premise”, the CA made two important findings: 1) it was not necessary for the Contractor to refer the failure to pay (the secondary dispute) back to the DAB; and 2) it was not necessary for him to refer the merits (the primary dispute) in the same single arbitration as his application to enforce.
