European Union – Employment. The Court of Justice of the European Union gave a preliminary ruling, deciding that art 4(1) of Directive (EC) 2008/104 (on temporary agency work) should be interpreted as meaning that: – the provision was addressed only to the competent authorities of the member states, imposing on them an obligation to review in order to ensure that any potential prohibitions or restrictions on the use of temporary agency work were justified, and, therefore, – the provision did not impose an obligation on national courts not to apply any rule of national law containing prohibitions or restrictions on the use of temporary agency work which were not justified on grounds of general interest within the meaning of art 4(1).
