Language refers to the national languages: Finnish and Swedish, the Sámi languages, sign languages, and depending on the case, also other languages and various dialects.
According to the Constitution of Finland, public authorities shall provide for the cultural and societal needs of the Finnish-speaking and Swedish-speaking populations of the country on an equal basis. Everyone has the right to use Finnish or Swedish when dealing with a state authority or an authority in a bilingual municipality. According to the Sámi Language Act, Sámi people always have the right to use Finnish or the Sámi language when dealing with the authorities in Sámi homeland.
Language-based discrimination may involve, for instance, a bilingual authority only providing services in Finnish, or a bank requiring the customers to understand the terms and conditions of a service agreement that is only available in Finnish or in Swedish.
