The value of linguistic diversity is addressed directly in Article 22 of the EU Charter of Fundamental Rights. However, other provisions of that Charter may also be relevant (and even more so than Article 22) for the effective protection of the linguistic rights and preferences of individuals across Europe. This paper focuses in particular on the significance of Article 21 of the Charter which prohibits discrimination (by the European Union itself and by its Member States when they implement EU policies) on a number of grounds, including language. The concrete meaning of linguistic equality (and linguistic discrimination) is explored in a number of specific contexts of European law and policy. This analysis is preceded by a discussion of the language component of the right to good administration, which is included as a separate right in the Charter.
