By a judgment dated 11^th December 2014 (in Case C-576/13) the European Court of Justice declared the illegitimacy of the Spanish legislation regarding ports (the so called “Ley de Puertos”) on the ground that it conflicts with the European principles on freedom of establishment, insofar as such legislation requires terminal operators to enroll or to become a stakeholder of a public company for the port work and to use the port workers of that company, with permission to hire workers on the market only in case of lack or inability of the workers supplied by the company.
