I have blogged about the Canadian FiT case at the WTO case here, here and here. News of Canada appealing the matter was reported here. It was not surprising since Canada had lost the case and was contesting the finding of the panel report that it had violated the provisions of the TRIMS and GATT.
Reports of the EU and Japan cross-appealing caught my attention. This would presumably be mainly on the interpretation of the provisions of the ASCM, especially the definition of a subsidy and benefit.
It is clear that the Appellate Body would decide the legal contours of this dispute, especially the compatibility of local content requirements with WTO law in the context of governments guaranteeing a minimum feed in tariff. With a number of countries across the world, both developing and developed, having massive renewable energy support programs (many of them with local content requirements), the AB ruling all be keenly awaited. One hopes that going by timeframe of the Antigua and Airbus-Boeing cases at the WTO dispute settlement, the wait for a closure is not too long!
