The regional council's investment company HBRIC is not content merely to fail - as it did by not establishing whether it could secure the necessary 22ha of conservation park before spending $20 million-plus planning a scheme that cannot be built without it - it must fail abjectly and miserably. And then cry to government to rescue it.
Which, sadly but predictably, the Nats seem prepared to do. Though how far such support can be stretched before the political fallout makes it untenable will be an interesting process to observe.
Right now, Ms Barry - better known as a former television garden-show presenter - seems happy to do HBRIC's hatchet work and fight against the law that governs the public estate she oversees.
But should her petition, which HBRIC is party to, seeking leave to appeal to the Supreme Court fail, there are even more diabolical options.
One, which HBRIC freely discussed and the HBRC countenanced this week, is to seek to make HBRIC a network utility operator (for irrigation) approved as a requiring authority under the Resource Management Act so the company can gain the power to use the Public Works Act to acquire any land it wants. Even Department of Conservation estate.
Taking DoC land would require the connivance of a Minister of Conservation willing to "downgrade" the land in question by revoking its existing status so as to enable it to be taken for a public work.
However, there is one snag in this cunning scheme, which is that the 22ha is not merely a "conservation area" but is part of a "specially protected" area: the Ruahine Forest Park.
Since the park is a 40-year old legal entity in its own right it seems to me Ms Barry would face the fraught task of having to revoke the status of the entire 932.6sq km of said park in order to then carve off the 22ha HBRIC wants so that it could take that bit for it reservoir.
Would she - or rather, John Key's Government - go so far as to enrage every even half-aware conservationist by doing something so drastic? With an election year coming up, and bearing in mind it would be a publicly notified process, I doubt it; but we shall see.
Meanwhile there's only a week to go to have your say on this and many other local issues. Post your votes today!
