Todd Tucker's Proposals for Investor-State Reform

This is from Todd Tucker, formerly of Global Trade Watch and now doing a PhD at Cambridge University:

Right now, investment treaty arbitration is making few people happy. Investors take years to launch and litigate them, and, best case scenario, they get payment – usually far less than what they asked for. Governments are certainly not happy: even having one of the cases brings their reputation into question, not to mention considerable financial resources to defend themselves and pay out.

So, and I am just spitballing here, instead of a 42-page, 13,975-word Model Bilateral Investment Treaty (as the US currently uses), how about the following roughly 250 words (or about 10 tweets):

The nice thing about this for the investors is that it allows them to bring up a dispute over ANYTHING, not just the kinds of problems that are covered by the (admittedly already malleable) standards like fair and equitable treatment. The nice thing about this for governments is that any recommendation from the arbitrators requires a recommendation that MUST be adjusted to take into account their policy prerogatives, or can be appealed to a group of appellate arbitrators controlled by states. But, again, another nice thing for investors is that they will get something within a year, even if that something is just finality and a recommendation to play nice with the host government. (Contrast this with 2-10 years under the current investment treaty system, before you end up with a cash award you can take to courts.)

Would this new approach make either side happy?
