Reuters reports on the interim report in DS397 (EC - AD Measures on Fasteners):
I'm looking forward to hearing more about what the Panel had to say on non-market economies, but it may be a while before this report is circulated publicly.In particular [the Panel] rejected the EU's approach to non-market economies, which effectively applies a single anti-dumping duty to the whole country rather than for individual firms, unless they can prove that they are independent of the state.
It means that the EU must now set individual duties on companies that want them, without unnecessary obstacles, instead of imposing a blanket duty for the whole country.
