From Gary Hufbauer:
The office of the US Trade Representative has taken the little noticed but highly unfortunate step of blocking Jennifer Hillman’s second term on the WTO Appellate Body. This is a bad omen, both for the World Trade Organization and the United States.
...
The United States has never before blocked its Appellate Body appointee from serving a second term. Since the USTR has offered no explanation for blocking Hillman, suspicions are bound to arise that the United States is displeased with her decisions on the AB and wants to name a judge who is more attentive to US positions in future cases.
These suspicions are bound to erode confidence in the WTO judicial system, and create a chilly reception for Hillman’s successor appointee. ...
