Opinion - Yesterday, the Supreme Court ruled that protected conservation land cannot be flooded for the $900 million Ruataniwha irrigation and water storage project.

Forest & Bird had challenged a deal between the Department of Conservation and Hawke's Bay Regional Council to acquire part of the protected Ruahine Forest Park so it could be flooded for the dam.
The scheme would see 22ha of protected land swapped for 170ha of nearby farmland.
Now the government has said it is considering legislating to ensure such land swaps could go ahead.
Any attempt to retrospectively reverse the court's decision in the dam case would be deeply offensive to the rule of law and a constitutional outrage.
It would deprive the litigants of the fruits of their forensic victory.
Why would the government appear and defend itself in court and then use legislation to overrule the decision when it loses?
Is that compatible with our democratic framework involving the separation of powers between the executive and the independent judiciary?

It is fine for the law to be changed prospectively if a judicial decision finds the law to be faulty in the view of Parliament.
But to change the situation retrospectively is wrong in these circumstances.
It would be yet another example of excessive executive power in New Zealand.
Such an action would be reminiscent of the decision to overturn the Clyde Dam legal decision by special legislation in 1982.
In many countries such an unconstitutional step would be impossible.
The court's decision makes it plain the government's land swap was driven by the dam proposal.
The Minister of Conservation Maggie Barry is disingenuous to say that the department was promoting conservation when the Director-General gave it the go ahead.
If not for the dam proposal, no such swap would have been contemplated.

It also appears that, from a conservation point of view, the land the Crown would have received in the swap was not as important as that given up.
It is government policy to subsidise irrigation developments.
It is also government policy to increase agricultural exports by the intensification of agriculture.
The government seems to be less interested in protecting the environment.
It is no use hiding behind the developer here.
Any such legislation would bring to mind the discredited National Development Act 1981 now repealed.
Think Big was a failure.
If such legislation is the intention of the government they should tell the public and let them make a judgment about it in the general election.
