Legislating from a Radical Hague: The United Nations Special Tribunal for Lebanon Invents an International Crime of Transnational Terrorism

Published online by Cambridge University Press:  27 May 2011


In 2011, the Appeals Chamber of the UN Special Tribunal for Lebanon purported to identify a customary international crime of transnational terrorism and applied it in interpreting domestic terrorism offences under Lebanese law. This article argues that the Tribunal's decision was incorrect because all the sources of custom relied upon by the Appeals Chamber – national legislation, judicial decisions, regional and international treaties, and UN resolutions – were misinterpreted, exaggerated, or erroneously applied. The Tribunal's laissez-faire attitude towards custom formation jeopardizes the freedom from retrospective criminal punishment, subjugating the human rights of potential defendants to the Tribunal's own moralizing conception of what the law ought to be. The decision is not good for international law or public confidence in its institutions and processes.

Elsewhere, the Decision draws upon extended modes of criminal participation under international law to supplement the extended modes under Lebanese domestic law. Paradoxically, in that context, the Appeals Chamber found that, where the international-law modes imposed wider liability than Lebanese law, they could not be applied out of fairness to an accused.

45 The Appeals Chamber unfortunately misquoted the Supreme Court here; the accurate quote should read: ‘This definition catches the essence of what the world understands by “terrorism”’ (not ‘what we understand’) (emphasis added).

58 For instance, the Court invokes an Organization of American States anti-terrorism convention to exclude terrorism from being regarded as a political or military offence for extradition purposes.

59 Quoted in Decision, footnote 133.

60 The decision itself was controversial as a whole; there were three dissenting opinions (compared to the majority of five) that challenged the majority's flawed assessment of customary law even as regards those other crimes.
