The AJEFNB, and many other organizations as well, used to play that role. Those organizations ensured, for example, that a sufficient number of bilingual judges were appointed and that the governments took both linguistic communities into account in developing measures to provide equal access to justice in both languages, so that bilingualism in the legal system did not lose ground. That was indeed an important part of the work they did.
