After the restoration of Lithuanian independence in 1918, the Lithuanian language became official thus penetrating every field of public life and shortly developing scientific, administrational (clerical) and publicist styles. The years of Soviet occupation (1940-1990) saw the propagation of bilingualism with the Lithuanian language being forced from public life by the Russian tongue. The status of Lithuanian as an official language was partially restored in 1989 by virtue of the Decree passed by the Presidium of the Supreme Council (the Restoration Seimas) "Concerning the Usage of the State Language". Restoration of the Lithuanian independence in 1990 lead to the development of a consistent policy for state language primarily focused on the integration of non-Lithuanian speakers into public life. In 1995, the Law on State Language of the Republic of Lithuania was adopted. The State Commission on the Lithuanian Language is in charge of the implementation of the law, while enforcement lies within the responsibility of the State Language Inspectorate and municipal language officers (see Organisation Chart below). The Institute of the Lithuanian Language, Lithuanian language departments at universities and other institutions are taking care of the correct usage and standardisation of the language.
