The official language of government agencies and local authorities is Estonian.
In localities where the language of the majority of the residents is not Estonian, local authorities may, to the extent and pursuant to a procedure provided by law, use the language of the majority of the permanent residents of the locality as their internal working language.
The use of foreign languages, including the languages of national minorities, in government agencies, in courts and in pre-trial procedure is provided by law. (Sec. 52)
