The return of Parliament tends to lower the tone of political discussion and harm the quality of government. Until the House reconvened this week the Prime Minister sounded intent upon an "elegant" settlement of differences with the Maori Party over the application of a Treaty obligation to state power companies the Government wants to float on the sharemarket.
Now, he is driven to remind the opposition he has the numbers to pass asset sale legislation without the Maori Party's support.
Maori, meanwhile, have filed a claim with the Waitangi Tribunal, seeking ownership of the water used by the electricity generators. To that, the Prime Minister retorted, "no one owns water. It's like air," he said. "No one owns air."
As a correspondent on the Herald letters page asks today, who is paying John Key's water bills? Fresh water in lakes, rivers and aquifer is not like air, it is a limited resource, capable of being owned, controlled, dammed or distributed in piped or bottled form for countless profitable purposes. Mr Key will need to find a better answer to this latest challenge to asset sales.
The Maori Council's lawyer, Donna Hall, concedes the Crown has steadfastly refused to acknowledge a proprietary claim to water, notably by Tainui who had to settle for a "guardianship" status over the Waikato River. Others point out that the Waitangi Tribunal is unlikely to revisit settlements so recently and solemnly made by Tainui and Ngai Tahu, whose domain includes the South Island hydro lakes.
