There is neither consensus whether the category of linguistic rights shall be distinguished, nor international agreement on the catalogue of such rights. Nevertheless, access to education in mother tongue constitutes a core element of most of the international and national frameworks of minority protection. Academic and legal disputes are particularly absorbing in Europe, where linguistic policies frequently intertwine with politics (e.g. Cyprus, Moldova, Ukraine). Thus, it is essential to pose the question, whether the right to education in mother tongue is always granted the equal scope of protection or is such protection differentiated by any additional criteria. Most of all, it shall be considered whether the analyzed right has an independent character or its protection is associated with perception of other fundamental rights and freedoms. This paper investigates the scope of the protection of this right within the framework of the Council of Europe.
