This contribution aims at establishing an understanding of what kind of language policy is needed to ensure that regulations on the use of minority and state languages do not lead to tensions or conflict. The examples examined include regulations such as those of Latvia and Ukraine, which were intended to promote the state language, as well as the regulation of Northern Macedonia, which significantly expanded the use of the Albanian language. The cases show the importance of striking a fair balance between the legitimate aim of promoting the use of the state language and the legal obligation to protect the linguistic rights of persons belonging to national minorities. Any differentiation between minority languages must be duly justified and minority representatives must be effectively involved in the drafting of such norms.
