Lawyers for Santos have told a court the gas giant was not legally required to consult a specific clan of traditional owners over its plans to drill in the Barossa gas field in the Timor Sea, north of Darwin.
The company launched an appeal on Tuesday against a landmark Federal Court decision that ruled its $4.7 billion Barossa gas project was invalid because the offshore gas regulator had failed to assess whether Santos had consulted with all "relevant parties", as required by law.
