The 111-Xian-Pan-6 Decision was the first judgment made by the Constitutional Court on a case of local self-government protection after the implementation of the Constitutional Court Procedure Act. There are two main points of contention in this case: 1. Is the safety tolerance standard for residual β-receptor hormone in imported meat and its products a matter of central or local legislation? 2. The Executive Yuan inform the petitioners and local councils by letter that the self-government regulations passed by them are invalid or not approved. Does it exceed the scope of the central government’s authority to supervise local self-government under the Constitution?
