Little wonder there is growing disquiet even in the US at the reach of this "free trade" deal, especially when the 12-nation Pacific Rim agreement is coupled with the EU-US one; together they will lock most of the world's significant economies (with the notable exceptions of Brazil, Russia, and India) into a situation where what a corporation says, goes.
Goodbye sovereignty; hello transnationalism.
Mind you, such dispute clauses already exist in New Zealand's trade deals with China, the 10 nations of Asean, and the new agreement with South Korea, and so far I'm not aware of any major hiccups.
But perhaps the Government spending $6 million to set up a "model farm" in Saudi Arabia - allegedly to remove objections delaying a trade deal there - is a "before the fact" reflection of such clauses; if, as Saudi businessman Sheikh Hamood Al Ali Khalaf has claimed, he lost "several hundred million" over the ban on live sheep exports, then smoothing ruffled feathers in this way now may prevent a suit seeking to overturn that ban later.
Cheap at the price, then; but an example of how such disputes might arise when the law of one country "unfairly" restrains trade in another.
Yet even admitting that some nations' laws are curious and their courts shonky, there is no real need for "independent" arbiters. As Auckland law professor Jane Kelsey points out, all an investor need do is take out appropriate risk insurance.
The good news is this week's "procedural snafu" (as pro-deal US politicos are downplaying it) may act to set back the whole agenda well into 2016 and even beyond. Indeed, it's possible Trade Minister Tim Groser - an inordinately keen TPPA champion - may no longer be in government by the time negotiations are completed.
Small comfort, given Labour's Phil Goff is also keen on it. But who knows? Maybe Winston Peters and the other opposing parties will have sufficient power to stop it by then.
I hope so. I don't like the thought of some multinational corporation telling us we can't use the "clean green" slogan because those words are their intellectual property, or that we have to allow GMO crops to be freely grown here because restricting the sale of franken-seed is "unfair".
That's the right of it.
