While no version of the Fast Track of the trade agreement has been released to the public, language in the recently passed Bipartisan Congressional Trade Priorities and Accountability Act of 2015, which authorizes the Fast Track declares that GMO labeling is an “unjustified trade restriction”!
Well, in short, no. In fact, GMO labeling would have to be considered by any honest advocate of free markets as one of those very rare trade regulations that absolutely is justified and would only enhance the proper functioning of consumer choice.
