Abstract: This article looks at the impact of human rights on other areas of law and the possible impact of a human rights codification in the EC in the context of the Draft Constitution. It examines how non-economic considerations, such as the social dimension, filtered into the body of EC law. First, they are rarely primary aims or competences of regulating the Common Market. Secondly, the article looks at the �social flanking� of economic rules, especially in the context of the free movement of workers. Thirdly, it points out that market freedoms may have social implications in specific areas, such as health care. Fourthly, it describes how social dimensions can be invoked when interpreting the scope and in order to justify restrictions of market freedoms. Fifthly, it notes that in recent case-law the European Court of Justice has given Union citizenship a social connotation by enforcing equal access of Union citizens to social benefits. The article then looks at social dimensions in EC competition law which safeguard the �level playing field� upon which the market freedoms operate. Against this backdrop, the final section of the article analyses the expected influence of a binding EU Charter of Fundamental Rights on the EU legal order. It discusses possible changes in the substance of human rights, with special regard to social rights, as well as in the application and interpretation of EC law in general and its normative hierarchies in particular. It also considers enforcement procedures by individuals and by the EU against Member States. The article goes on to weigh the danger that codification could encroach upon the competencies of Member States against the potential benefits of a more coherent legal system. It concludes by asking whether codification of human rights is likely to encourage more public engagement with the EU.

Abstract: Causing Refugee Flows as a Delict under International Law. International Responsibility of the State of Origin for Causing Refugee Movements.The book applies the international law of state responsibility to the situation in which a state expels its own population; the context is a preventative approach.It focuses on how the receiving state's sovereignty may be violated by the obtrusion of unwanted people. It discusses how the principles of state responsibility evolved and were moulded in the International Law Commission's Articles, paying particular attention to their application in a refugee context, such as to causation and attribution of the acts leading to refugee movements. It examines which primary norms of international law are violated, and the legal consequences of such violations.Primary norms may be violated at three levels: first, individual human rights, such as of the right to free movement, nationality rights and the right to a home(land). Secondly, 'rights' of states: the book analyses refugee movements since 1917, especially, from Nazi Germany, as dealt with in the League of Nations institutions. This reveals an emerging opinio iuris and state practice supporting the thesis that causing refugee movements may violate the receiving state�s sovereignty, and, therefore, amounted to a violation of international law even before the emergence of international human rights law. Thirdly, it examines whether obligations owed to the international community as a whole exist and are violated, discussing the concept of 'international community' and the relationship between the concepts of international crimes, erga omnes obligations and ius cogens.The book then looks at the consequences of internationally wrongful acts in a refugee context, especially, reparation, compensation and guarantees against repetition. It concludes by analysing the possible implementation of such consequences by states, with a special focus on unilateral and collective humanitarian intervention.
