Court of Justice of the European Communities
Union royale belge des sociétés de football association ASBL v Jean-Marc Bosman and others
Case C-415/93, 15 December 1995
(excerpts)
§ 79 As regards the arguments based on the principle of freedom of association, it must be recognized that this principle, enshrined in Article 11 of the European Convention for the Protection of Human Rights and Fundamental Freedoms and resulting from the constitutional traditions common to the Member States, is one of the fundamental rights which, as the Court has consistently held and as is reaffirmed in the preamble to the Single European Act and in Article F(2) of the Treaty on European Union, are protected in the Community legal order.
§ 80 However, the rules laid down by sporting associations to which the national court refers cannot be seen as necessary to ensure enjoyment of that freedom by those associations, by the clubs or by their players, nor can they be seen as an inevitable result thereof.
