As Argentina’s new president Mauricio Macri sets himself to the task of reversing the direction of the nationalist politics of the Kirchner era, Spain’s Abertis has moved a 12-year lawsuit against Argentina to the World Bank’s International Center for Settlement of Investment Disputes (ICSID).

At issue are caps imposed by the Kirchner government on the tolls that Abertis charges on two highways serving Buenos Aires. With these caps in place, the highways have run up heavy operating losses. After exhausting the available court and legal remedies in Argentina, Abertis last year moved its case to ICSID, where it was registered on December 17.
