Judgment_paragraph 19 · Anita Groener v Minister for Education and the City of Dublin Vocational Educational Committee (C-379/87)

19The EEC Treaty does not prohibit the adoption of a policy for the protection and promotion of a language of a Member State which is both the national language and the first official language. However, the implementation of such a policy must not encroach upon a fundamental freedom such as that of the free movement of workers. Therefore, the requirements deriving from measures intended to implement such a policy must not in any circumstances be disproportionate in relation to the aim pursued and the manner in which they are applied must not bring about discrimination against nationals of other Member States.
