"Based on the request filed today, we think the EU's new claims lack any foundation," USTR Chief Counsel Tim Reif said in an emailed statement after the EU filed a new dispute with the World Trade Organization. 

"In addition, the EU’s filing of yet another complaint, before the panel in the ongoing compliance proceeding has even released its decision, is another example that they are not serious about moving toward a constructive resolution. When the EU is ready to resolve this dispute on the basis of WTO rules, rather than just dragging it out, they will find us ready."
