There’s an international awakening afoot about a radical expansion of corporate power — one that sits at the center of two historic global trade deals nearing completion. . . . The system of closed-door trade tribunals has been around for decades now, nestled like a ticking time bomb into hundreds of smaller bilateral trade agreements between nations. But not so long ago, the trade tribunal system wasn’t the stuff of high-profile op-eds by U.S. senators. It was virtually unknown except among a small cadre of international lawyers and trade specialists. The case that brought the system into broad public view was born 15 years ago this month on the streets of a city high in the Andes. How that case was won holds powerful lessons today for the battles over the TTIP, the TPP, and the effort to hand global corporations enormous new legal powers.
