Sources of doubt, sources of duty: HLA Hart on international law

In many ways HLA Hart’s critical analysis of the concept of law, with its repudiation of simple command theories of legal obligation, is at the same time a critique of the notion of state sovereignty. It is therefore an adumbration, if no more, of a radical reconceptualisation of international law, one which redefines the distinction between municipal and in-ternational jurisdiction. This paper is an exploration of what Hart could or ‘should’ have said about international law, based as much as possible on what he did say about international law and law in general. After some introductory comments it outlines Hart’s general analysis of law, with particular reference to the relevance for our understanding of international law.

Good global governance : custom, the cosmopolitan and international law

International law has both less and more to offer to the cosmopolitan project than one might think. As currently understood, international law presages a global system of obligations comprising the convergent systems of universal customary international laws and near-universal conventional instruments (treaties), both of which legal forms are characterised by natural law tendencies. From the point of view of a pluralistic cosmopolitanism, this is a dead end. Thinking beyond these formulae requires that international law be treated as a species of general law rather than state-centred law.

The problematic relationship between customary international law and the domestic courts

The relationship between international law and domestic law has long been problematic. This article considers in particular the enforcement of customary international law through an analysis of judicial practice in England and Australia. The examination of the jurisprudence suggests that domestic judges often feel uncomfortable when asked to apply international law in the domestic courts and struggle to somehow justify its use. This has led to an inconsistency in judicial practice in the application of international law in jurisdictions such as Australia. However, ultimately the monist theory that recognizes that customary international law automatically flows into the domestic law appears to be reflected in an emerging trend in judicial practice in the common law judicial systems under consideration. However, the article suggests that the English courts now see international crimes as an exception to that theory and require domestic legislative transformation. Ultimately the article concludes that the municipal courts provide an important forum for the enforceability of customary international law, including human rights norms.
