The current United States administration, under President Donald Trump, has been at its most intransigent when it comes to the institutions that underpin the global trading system, particularly the appellate body at the World Trade Organization (WTO). The appellate body is supposed to have seven judges, who rule on cases brought by a WTO member against another suspected of flouting trade rules. But the US has blocked new appointments to the court — a process that predates Mr Trump, but sped up under his administration — and this month the court will likely lapse because of a shortage of manpower. Two of the last three judges are due to retire, and cases cannot be heard with just one judge. This would have global consequences. Since 1995, the appellate body has been central to the larger project of ensuring that global trade does not turn into a might-makes-right dystopia where larger countries such as the US and China can flout agreed-upon rules at will, and intimidate smaller countries into compliance. Such countries would not win a bilateral trade dispute, but have a chance of getting their way at the WTO. This is, of course, precisely why the “America first” Mr Trump disdains the system.
