Port of Newcastle Operations Pty Limited v Glencore Coal Assets Australia Pty Ltd & Ors

The dispute before the High Court of Australia concerned the interpretation of a port services agreement between Port of Newcastle Operations Pty Limited (the operator) and Glencore Coal Assets Australia Pty Ltd and others (the coal producers). The coal producers sought to recover certain charges paid to the operator under protest, alleging that these charges were not authorised by the agreement.

The central legal issue was whether the operator was entitled to levy charges for services that were not explicitly provided for in the port services agreement, particularly in circumstances where the agreement stipulated that the operator would provide services "as required" and that the operator would be "entitled to charge for services rendered". The High Court was required to determine the scope of the operator's entitlement to charge for services and the proper construction of the agreement in light of the parties' conduct.

The High Court held that the agreement did not grant the operator an unfettered right to charge for any service it chose to provide. Instead, the entitlement to charge was confined to services rendered in accordance with the agreement. The Court reasoned that the phrase "as required" indicated that the operator's obligation to provide services was triggered by the needs of the coal producers, and that the entitlement to charge was for services rendered in response to those requirements. The Court emphasised that the agreement was a commercial contract and should be construed according to its plain language, without implying terms that were not present. The Court found that the charges in question were not authorised by the agreement, as they related to services that were not requested or required by the coal producers under the terms of their agreement.

The High Court allowed the appeal, setting aside the orders of the primary judge and the Court of Appeal, and remitted the matter to the primary judge for determination of the amount of the refund to be paid to the coal producers.
