IIUC WTO trade schedules can be unilaterally set, but are open to dispute and, when disputes are resolved, “certification”.
Schedules can exist and take effect while not certified.
I have read the following:
The other 163 WTO Members (actually, 27 of these are EU Member States, so there are fewer voices than that) do not have a veto over the UK’s scheduled commitments.
They do have a veto over the certification of these schedules. But certification has merely evidentiary weight. It is like coronation. The UK’s scheduled commitments exist even if they are not certified, just as a monarch is a monarch prior to coronation. Indeed, the EU itself has not traded under certified schedules since 1974. The sky has not fallen.
So some or all EU trade schedules remain uncertified. Is this correct and if so what are the implications (if any)?
