The World Trade Organization’s capacity to settle international disputes, a core function throughout the body’s 25-year history, is on the brink of collapse following relentless US opposition.

The appellate branch of the WTO’s Dispute Settlement Body (DSB), sometimes dubbed the supreme court of world trade, was a target of US criticism before President Donald Trump took office.

His predecessor Barack Obama’s administration began a policy of blocking the appointment of appeals judges over concerns that their rulings violated American interests.

Trump’s trade team has both extended that policy and escalated the fight.

Barring a shock breakthrough in the coming days, the court will cease functioning on Wednesday.

The WTO appellate branch normally counts seven judges but has just three left — the minimum required to hear an appeal. Two more judges are due to retire on Tuesday.
