This is from a paper about WTO dispute settlement published on the ICTSD website as part of the E15 process:
there is evidence that the existing ... perception that claims under Article 2.2 of the Agreement on Technical Barriers to Trade (TBT Agreement) are extremely difficult to win is having a deterrent effect on potential complainants pondering whether to bring claims under this provision.
What happens if governments stop bringing Article 2.2 claims? Is that a problem? Or is that a solution?
