The national judicial review is harmonized through principles of Community law; in particular those of direct effect, supremacy, Community-conform interpretation of national law, state liability, member states' institutional and procedural autonomy, non-discrimination and effectiveness, through Directives 89/665/EEC and 92/13/EEC, and through the GPA.
