Abstract

Contemporary legal practice requires the allocation of authority within a complex system of legal prescriptions. As international law has extended to areas as diverse as trade, environmental regulation and human rights, the consequences of breach of international legal obligations become more difficult to assess. The authors probe the role of the <it>lex specialis</it> maxim as a tool for the effective placing of special secondary rules within the general international law of state responsibility. The central question is: Are the general rules on state responsibility to apply residually? The authors answer in the affirmative. ‘Conceptual’ arguments for so-called self-contained regimes are unconvincing. Scholars who perceive international law as a unified legal order might be led to apply a presumption in favour of the applicability of the general international law of state responsibility. Scholars who regard international law as no more than the sum total of loosely interrelated subsystems tend to advocate a presumption in favour of the normative closure of a particular regime. In the authors’ view, neither presumption is helpful, since both tend to obfuscate the value judgments that legal decision-making inevitably involves. Instead, the authors propose that a fallback on general international law, including resort to countermeasures, may be justified on normative grounds. A closer analysis of four subsystems that have often been associated with the notion of self-contained regimes – diplomatic law, European Community law, the WTO and human rights – concludes the discussion.
