The Commonwealth admits it failed over allegations it expedited a gas exploration contract in the Northern Territory in a bid to stymie a climate change-inspired legal challenge.
The Environment Centre NT is attempting to stop Imperial Oil and Gas's drilling program in the Beetaloo Basin, arguing in the Federal Court that the government grant was unlawful.
It says federal Resources Minister Keith Pitt should have considered the negative climate change impacts that developing the onshore shale gasfield could have before he awarded a $21 million grant.
The ECNT's lawyers also allege that the funding contract, which was signed on September 9, just days after they applied for an urgent court hearing, was an attempt to interfere in the case.
The Commonwealth's lawyer Tom Howe QC says it's a serious accusation of misconduct and the federal government accepted that what happened "was a departure from model litigant standards".
"We also accept the Commonwealth didn't cover itself in glory and it fell short of this court's expectations," he said on Wednesday.
"What happened involved disrespect to the court and disrespect to the applicant."
Mr Howe said the Commonwealth should have written to the ECNT and given it reasonable notice that it was able to make an application to the court to stop the grants.
He said the "left arm" and the "right arm" of various government agencies hadn't coordinated their activities.
"That should have happened and that is quite regrettable conduct," he said
Mr Howe agreed with Justice John Griffiths that the timing of the grants contract denied the ECNT the opportunity to use the courts to stop it.
However, he was critical of the ECNT legal team, saying it hadn't provided enough detail for the unnamed person who was alleged to have engaged in the wrongdoing to respond.
"The allegation isn't supported by any direct evidence, whatsoever," Mr Howe said.
"Inferences should not be drawn by faint fingerprints on the sand."
Earlier, the court heard Mr Pitt wasn't required to make inquires about matters such as the impact of climate change, when he was deciding whether to help fund Imperial's exploration.
Under section 71 of the Public Governance, Performance and Accountability Act, the minister only needed to satisfy himself that the expenditure was a proper use of public money.
The decision can be subjective and doesn't need to be objective, and any inquiries that are made don't need to be recorded.
"The minister's satisfaction is the sole criteria of operation," Mr Howe said.
Mr Howe said Mr Pitt also wasn't required to consider the validity of the government energy policy regarding the Beetaloo Basin when he awarded the grant.
"The fact there were climate risks might be regarded by some as disqualified," Mr Howe said.
"Once the policy is adopted the question shifts to the financial management of the funding of that policy choice."
Mr Howe said the ECNT seeks to impose an extraordinary and intolerable burden of decision-making on the minister that could impact Indigenous rights.
"The minister has to make inquiries then depending on the outcome of those, run various bunnies into various burrows to ascertain if something is relevant," he said.
The NT also has legislation to protect the environment and it was in the process of bolstering these after accepting a fracking inquiry's recommendations, Mr Howe said.
The Beetaloo sub-basin has been estimated to hold more than 200,000 petajoules of gas. The extraction and consumption of gas from this precinct would equate to a 13 per cent increase on Australia's 2020 greenhouse gas emissions, according to one expert report.
The court reserved its judgment.
