Mr Goddard argued the council's action was "founded on a misconception" because it was effectively challenging the legislation, rather than the Cabinet's actions. He said the court could not review that legislation "even if it is dressed up as a challenge" to what the executive or ministers were doing to enact it.
"In effect what is sought is a review of legislation and that's outside the proper functions of the court."
In going ahead with the necessary steps towards selling the shares, the executive was "doing precisely what Parliament has authorised".
Furthermore the decision to bring the legislation into force was not reviewable by the court on the grounds it breached the treaty provisions of the SOE Act or Public Finance Act because ministers were not required to form a view on that.
"It is not the role of the executive to review whether the Treaty safeguards in the legislation are adequate or need to be supplemented with additional protective measures."
Leaving those arguments aside, Mr Goddard said the sale of up to 49 per cent of the shares in Mighty River and other power companies "is not inconsistent with the principles of the Treaty". He returned to the point made by Justice Young earlier in the hearing that anything the Government could do to make redress for Maori rights and interests in water could be done following the sale of shares.
"Ownership [of Mighty River Power] is completely irrelevant."
Justice Young heard Mr Goddard's submissions quietly with few interruptions, in contrast to his constant tough questioning of the Maori Council's presentations.
At one point, Justice Young told the council's lawyer Felix Geiringer to "take a deep breath and count to 10" and to "remember where you are" during a heated exchange over Prime Minister John Key's statements that "no one owns water".
