Guardian enviro-scribe, George Monbiot, hates NAFTA. He thinks it a scam perpetrated without the consent of the peoples of Canada, America and Mexico by their political bosses. Monbiot especially detests the ISDS or Investor-State Dispute Settlement clause. He also defends Donald Trump's demand for a 5-year "sunset clause."
In seeking to update the treaty, governments in the three countries have candidly sought to thwart the will of the people. Their stated intention was to finish the job before Mexico’s presidential election in July. The leading candidate, AndrĂ©s Lopez Obrador, has expressed hostility to Nafta, so it had to be done before the people cast their vote. They might wonder why so many have lost faith in democracy.
Nafta provides a perfect illustration of why all trade treaties should contain a sunset clause. Provisions that made sense to the negotiators in the early 1990s make no sense to anyone today, except fossil fuel companies and greedy lawyers. The most obvious example is the way its rules for investor-state dispute settlement have been interpreted. These clauses (chapter 11 of the treaty) were supposed to prevent states from unfairly expropriating the assets of foreign companies. But they have spawned a new industry, in which aggressive lawyers discover ever more lucrative means of overriding democracy.
The rules grant opaque panels of corporate lawyers, meeting behind closed doors, supreme authority over the courts and parliaments of its member states. A BuzzFeed investigation revealed they had been used to halt criminal cases, overturn penalties incurred by convicted fraudsters, allow companies to get away with trashing rainforests and poisoning villages, and, by placing foreign businesses above the law, intimidate governments into abandoning public protections.
Under Nafta, these provisions have become, metaphorically and literally, toxic. When Canada tried to ban a fuel additive called MMT as a potentially dangerous neurotoxin, the US manufacturer used Nafta rules to sue the government. Canada was forced to lift the ban, and award the company $13m (£10m) in compensation. After Mexican authorities refused a US corporation permission to build a hazardous waste facility, the company sued before a Nafta panel, and extracted $16.7m in compensation. Another US firm, Lone Pine Resources, is suing Canada for $119m because the government of Quebec has banned fracking under the St Lawrence River.
As the US justice department woke up to the implications of these rules in the 1990s, it began to panic: one official wrote that it “could severely undermine our system of justice” and grant foreign companies “more rights than Americans have”. Another noted: “No one thought about this when Nafta implementing law passed.”
Nafta obliges Canada not only to export most of its oil and half its natural gas to the US, but also to ensure that the proportion of these fuels produced from tar sands and fracking does not change. As a result, the Canadian government cannot adhere to both its commitments under the Paris agreement on climate change and its commitments under Nafta. While the Paris commitments are voluntary, Nafta’s are compulsory.
Were such disasters foreseen by the negotiators? If so, the trade agreement was a plot against the people. If not – as the evidence strongly suggests – its unanticipated outcomes are a powerful argument for a sunset clause.
...Those who defend the immortality of trade agreements argue that it provides certainty for business. It’s true that there is a conflict between business confidence and democratic freedom. This conflict is repeatedly resolved in favour of business. That the only defender of popular sovereignty in this case is an odious demagogue illustrates the corruption of 21st-century liberal democracy.
...Trump was right to spike the Trans-Pacific Partnership. He is right to demand a sunset clause for Nafta. When this devious, hollow, self-interested man offers a better approximation of the people’s champion than any other leader, you know democracy is in trouble.
