In the thesis the aim was to compare the EU legal system with the Swedish national legal system with specific focus on gender discrimination law. Findings showed Sweden applied discrimination law in accordance with EU directives but went further than what the Gender Recast Directive, and the EU law itself, required of it. Findings also revealed Sweden uses bi- and multilateral agreements to further EU discrimination law. If such agreements are in accordance with EU primary laws, to which Sweden as a member state has agreed to follow when it acceded to the Union, such agreements will be accepted by the Union. Other findings were related to the Union institutions themselves. These institutions are much more co-dependent than was originally thought and the democratic function of the institutions are treaty secured as far as voting in of representatives to the Parliament give EU citizens power to influence legislation of the EU, likewise the European Citizens’ Initiative giving each EU citizen a chance to propose new legislation. Regulations that are deemed, by member states, to be in breach of EU primary law can be tried and interpreted by the Court of Justice of the European Union and if said regulation is deemed being in breach of EU primary law it can be annulled.
