Abstract
This paper explores the connections between the law and language in the European Union. The paper concerns the language policy of the European Union (EU) and English language priority. The EU faces challenges of finding a common ground for respecting the diversity of its members. So many different states are gathered in one organisation which establishes the law for diversified legal orders. The research question is - which language(s) is or should be used in the EU? Does English become lingua franca of the EU?
