Santos TOGA Pty Ltd v KGLNG E&P Pty Ltd

Santos TOGA Pty Ltd and others (Santos) v KGLNG E&P Pty Ltd and others (KGLNG) involved a dispute between the parties regarding the interpretation and effect of certain agreements, including a Settlement Agreement and various royalty agreements. The central issue was whether KGLNG was bound by an arbitration award concerning the calculation of royalties payable to a third party, Tri-Star, under the Settlement Agreement. Santos argued that KGLNG, by participating in the arbitration process and showing interest in its progress, was bound by the arbitration award. KGLNG contended that the arbitration award did not bind them as they were not parties to the arbitration and did not have a privy interest in the outcome.

The court examined the principles governing privity of interest, emphasizing that for a party to be bound by an earlier proceeding, they must have a legal interest identical to the one at stake in the later proceeding. The court noted that mere economic or other non-legal interests were insufficient. Additionally, the court analyzed whether KGLNG had any legal interest in the outcome of the arbitration that was represented by Santos. The court concluded that KGLNG's interests in the joint venture and the obligation to share the royalty burden did not constitute a privy interest in the specific legal obligation determined by the arbitration award. Therefore, KGLNG was not bound by the award.

In reaching its decision, the court highlighted that the legal interest protected in the arbitration was distinct from the interest KGLNG had under the royalty agreements. While both parties shared an economic interest in the joint venture's success and the burden of the royalty obligation, this shared interest did not equate to a privy interest in the specific legal obligations determined by the arbitration. The court further noted that KGLNG had not authorised or controlled the arbitration, nor were their interests represented by a party owing them fiduciary obligations. Consequently, KGLNG was not bound by the arbitration award.

The court directed the parties to confer and submit a draft order reflecting the findings and conclusions, including any agreed orders regarding the costs of the arbitration. If the parties could not agree, they were to submit their own draft orders and written submissions.
