European and Domestic Law

Chapter 4 turns to the domestic law of the countries of Europe, arguing that the combination within European public law of EU law, the law of the ECHR, and of domestic law cannot be conceived of along the lines of a pyramidal hierarchy. The chapter examines the ways in which the different European domestic legal systems conceive of the relationship between international law and domestic law. The chapter then looks at the relationship between international law and domestic law through a constitutional lens, an approach which more and more domestic courts in Europe seem to be adopting. The chapter then turns to the integrated legal order of the European Union, a legal order distinct both from domestic and general international law. Finally, the chapter teases out and analyses four shared guiding principles of European public law: equality and non-discrimination; proportionality; subsidiarity; and legal certainty.
