The principle of legality has spread and has received a certain recognition at the international with a more or less effective judicial sanction.
United Nations The principle is stated in Article 11, paragraph 2 of the
Universal Declaration of Human Rights of 1948: Nonetheless, it is not a legally binding text: it therefore cannot be invoked in the national or international jurisdictions of States which have signed the
Universal Declaration. This is not the case with the
International Covenant on Civil and Political Rights (ICCPR): Still, this judicial instrument leaves considerable leeway to the judge of that country, and the
United Nations Human Rights Committee, is not recognized as a jurisdiction whose decisions are binding on individual States. The interpretation of this pact, and thus of the principle of legality as it is enshrined in it, is therefore a function of the interpretation of the national judge, in the case of signatory states.
European Convention on Human Rights The
Convention is the only international human rights treaty whose judicial effect is guaranteed by an independent jurisdiction, the
European Court of Human Rights. Article 7, §1 of the
Convention enunciates thus the principle of legality in criminal matters: This provision refers to "national law" rather than to "national legislation" (in the formal and strict sense of the word), to remain compatible with
common law legal systems. The European Court of Human Rights only has jurisdiction if the national legal system has already ruled: it may however have an independent interpretation of the
Convention and notably determine what it considers a criminal matter. The European judicial system may of its own accord qualify a matter as criminal, based on the nature of its penalty or on its gravity. Thus, in countries with dual legal jurisdictions, such as France, administrative authorities empowered by the legislature to impose administrative penalties may see themselves applying Article 7. However, the Convention expresses a reservation as to
crimes against humanity. At the time they were committed, such crimes were not made illegal by a criminal law text. The need to punish the authors of crimes was thus expressed from respect for the "general principles of law recognized by civilized nations", thus tempering the principle of legality enshrined in the
Convention. ==See also==
