IIRC, the International Criminal Court. They accept judges that would be qualified in their home country. With the US stepping out of it, one of the ICC’s biggest funders is Japan. They have a history of paneling judges who are just people of the community with no specific legal training . Maybe that works for them, but it meant some unqualified judges were sent to the ICC from Japan. The ICC isn’t in a position to stop them, given the funding situation.
