프랑스 헌법상 공용어주의와 지역어 보장에관한 연구 - 프랑스 헌법재판소 결정례를 중심으로 -

France defined ‘the republic's language as French’ in Article 2, Clause 1 of the constitutional law in 1992, thereby having adopted the official language policy. The official language policy is what forces people to use official language in the public sphere while a country prescribes one language as official language. Even in France that chose the official language policy, the problems are being raised in relation to a rise in refugees according to the intensification of civil war in the Middle East, to the influx of immigration on financial grounds, and to the regional language users. To bring forward directionality of solving these issues, there was an attempt to resolve problems relevant to language as the revision of the Constitution in 2008 was stipulated the regional language in Article 75 of the constitutional law. A change in the official language policy of France is related to the republic, to the people's unity, and to the equality before the law, which are the basic principles in light of the French Constitution. In this study, first, the aim is to analyze the official language regulation in Article 2 of the French Constitution, and the regional language, which was prescribed in Article 75. Second, the objective is to analyze a significance of the official language policy in light of the French Constitution focusing on the decisions of the Constitutional Court. Especially, the aim is to intensively analyze the decisions of the Constitutional Court pertinent to the Toubon law, which specifically guaranteed the official language policy, andto the European Charter for Regional or Minority Languages. Third, the objective is to analyze a specific realization plan for protecting regional language in terms of the language rights relevant to an individual's identity based on this analysis.
