The NSW Supreme Court has ruled that Centennial Coal must make some the port capacity at Newcastle available to Xstrata Coal.
As part of the sale of the Anvil Hill Project to Xstrata in October 2007, Centennial would allow access to the new coal terminal being built by the Newcastle Coal Infrastructure Group (NCIG).
Centennial said in a statement, that Xstrata had also agreed to assist in obtaining additional port capacity through the existing Port Waratah coal terminal.
However, after more than a year of negotiations, both parties had been unable to resolve the issue and referred it to the NSW Supreme Court, the company said.
The Court ruled on 10 August that Centennial will be required to make port capacity in NCIG available in the future for Xstrata.
The company said it remains confident the decision would not have an immediate effect and that sufficient port capacity will be available for growing exports in the future.
