Yet at the same time, the OIO has been found to have erred in relating the requirement for economic benefit to other potential New Zealand buyers.
"It advised the ministers that the act does not require an overseas investor to do more than a New Zealand investor would do, but asks only whether the investment is likely to benefit New Zealand," Justice Miller notes. Therefore, it treated the likely behaviour of any alternative buyer as irrelevant.
All things being equal, there should be no question that the farms should go to Shanghai Pengxin, which has agreed to pay the Crafar receivers considerably more than New Zealand investors, including the consortium led by Sir Michael Fay, believe they are worth. That, indeed, remains the most likely outcome.
Justice Miller says that a reconsideration incorporating the likely behaviour of any alternative buyer need not take long.
"On the face of it, the OIO may simply recalibrate its existing recommendation," he says.
But whatever happens, and whatever the Government's protestations that there is no damage to New Zealand's image, the High Court ruling has highlighted, once again, the muddy waters of the overseas investment regime. This has enabled Sir Michael, not for the first time, to use a legal challenge to upset what appeared to be the normal order of things. The saga over the Crafar farms is beginning to bear more than a passing resemblance to his extraordinary America's Cup big-boat escapade.
Justice Miller's ruling will not go unnoticed by overseas investors. They want certainty, not the possibility of an application being overturned in this manner even after a series of special conditions had been accepted. It is time that a clear set of principles was adopted - and adhered to.
