This article deals with the exclusion of non-profit-making entities from the right of freedom of establishment of Articles 49 and 54 TFEU. It analyses the historical reasons for this exclusion. It is argued that the exclusion from freedom of establishment is no longer justified on the basis of two elements. Firstly, the development of the jurisprudence of the European Court of Justice in the fields of competition law, free movement of capital and tax law makes such exclusion systematically no longer tenable. Secondly, a law and economics treatment of non-profit firms as organisations that efficiently provide services in alternative to for-profit firms weakens the reasons for the exclusion. The article proposes a uniform, European notion of non-profit entity based on a law and economics analysis of this type of firm for the purposes of Article 54 TFEU as opposed to possible different national notions. This is followed by a brief analysis of the hypothesis of regulatory competition among jurisdictions for the law regulating the corporate governance of non-profit entities.
