A visegrádi négyek nyelvi kartával kapcsolatban tett kötelezettségvállalásai mint a nemzetközi szokásjogi norma azonosításának lehetséges bizonyítékai

This article focuses on the commitments made by the four Visegrád countries – the Czech Republic, Hungary, Poland, and Slovakia – under the Council of Europe’s 1992 European Charter for Regional, and Minority Languages. The analysis intends to identify the overlapping commitments of all of the V4 countries that were recognized in the ratification process of the Language Charter. In addition, I refer to the relevant reports of the Committee of Experts – the Language Charter’s primary monitoring mechanism – in order to identify whether or not these states have fulfilled their commitments. Additionally, this comparative study aims to obtain information on the customary legal status of the norms involved in these commitments. It also considers the potential for a ‘minority issue’ to rise to the level of a Visegrád priority.
