That isn't what we said. Sometimes, the regulatory authorities translate the documents themselves so that there are two versions and the regulated persons can have better access.
Obviously, the decision to translate a document comes under the regulatory authority. However, harmonization and international co-operation or even a highly technical document are usually considered by the Supreme Court to be acceptable reasons for a unilingual version. A unilingual document is sometimes acceptable so as not to compromise the unique nature of the expertise of the document that will be incorporated by reference.
