The International Rule of Law

  • Chapter
  • First Online:
International Conflict and Security Law

Abstract

The chapter explores the significance of the international rule of law for international conflict and security law. The first section of the chapter investigates how the international rule of law is conceptualised, unpacking its formal and substantive requirements. The second section applies the concept in the context of international conflict and security law, focusing in particular on the implications for the use of lethal force. In doing so, an argument is advanced for the prioritisation of compliance with both formal and substantive requirements of the international rule of law. Necessary for the maintenance of international peace and security, and for the prevention and punishment of international crimes, emphasis is placed on the importance of the international rule of law for the integrity of the international legal order and for the future development of international conflict and security law.

Notes

  1. 1.

    During recent decades, the international rule of law has become a widely-discussed topic. We base our analysis on works by Beaulac 2009, Chesterman 2008, Hurd 2014, 2015a, 2015b, Nardin 2008, Nollkaemper 2009 and others.

  4. 4.

    ‘A principle of governance in which all persons, institutions and entities, public and private, including the State itself, are accountable to laws that are publicly promulgated, equally enforced and independently adjudicated, and which are consistent with international human rights norms and standards. It requires, as well, measures to ensure adherence to the principles of supremacy of law, equality before the law, accountability to the law, fairness in the application of the law, separation of powers, participation in decision-making, legal certainty, avoidance of arbitrariness and procedural and legal transparency.’

  10. 10.

    The idea behind the ‘thin’ version of the rule of law is that law is considered to be morally indifferent. See Raz 1979, pp. 212–218.

  14. 14.

    Gowder insists that the ‘thin’ and ‘thick’ rule of law are better called the ‘weak’ and the ‘strong’ versions of the rule of law. Formal legality is ‘weak’ exactly because it does not encompass substantive values represented by the rules of law. For instance, the requirement of equality can be treated formally through the formula ‘treat like cases alike’, yet to determine which cases are indeed ‘like’ and which are not, one must always consider the substance of the rules. Gowder 2016, Chapters 2–3.

    Kumm 2003–2004, p. 19.

  16. 16.

    As noted by Raz, these requirements do not exist for their own sake. They simply determine some minimal qualities any law must possess so that its addressees can be guided by it, see Raz 1979.

  17. 17.

    This list of formal qualities of legal rules is not exhaustive. One of the most widely recognised lists of such formal qualities of law is offered by Fuller (see Fuller 1964; for the application to international law, see also Kumm 2004; Brunnée and Toope 2010). It is beyond the scope of this chapter to discuss all the intricacies of formal legality in international law.
