From a quick google search, it would appear that the proceedure is thus:-
Failure to carry out recommendations of Commission of Inquiry or ICJ
1. In the event of any Member failing to carry out within the time specified the recommendations, if any, contained in the report of the Commission of Inquiry, or in the decision of the International Court of Justice, as the case may be, the Governing Body may recommend to the Conference such action as it may deem wise and expedient to secure compliance therewith.
In the case of forced labour in Myanmar they suspended Myanmar's participation so they couldn't come to ILO meetings anymore and wrote lots of memo's asking member nations to review their relations with said country.
. . . I'm not convinced that this is going to have much effect on the EPO.
