5 For example, nuclear weapons are not subject to an explicit legal prohibition against their use despite widespread recognition that such weapons should be abolished. In December 1994, the UN General Assembly requested the International Court of Justice to offer an advisory opinion on the question: ‘Is the threat or use of nuclear weapons in any circumstance permitted under international law?’ To the central issue of permissibility of nuclear weapons, by a vote of seven to seven decided through the second vote of the President of the Court, the judges ruled that: ‘The threat or use of nuclear weapons would generally be contrary to the rules of international law applicable in armed conflict, and in particular the principles and rules of humanitarian law. However, in view of the current state of international law, and of the elements of fact at its disposal, the Court cannot conclude definitively whether the threat or use of nuclear weapons would be lawful or unlawful in an extreme circumstance of self-defence, in which the very survival of a State would be at stake. So while the threat or use of nuclear weapons was generally held to be against international law, the judges could not determine that it always would be. Just as what would constitute “the very survival of a State” was not defined. In many respects, the decision could be characterized as a decision not to decide, at least not to determine once-and-for-all the matter of legality’.

A further three states, Denmark, France, and Germany, are thought to have formal review processes, but information about these processes does not appear to be publicly available.

59 The Commentary to Article 36 endorses a conservative approach regarding which uses of weapon should be considered, confining the analysis to ‘normal or expected use’. Fry takes the view that the Commentary (and, by extension, the Guide, which endorses this aspect of the Commentary) takes an unnecessarily narrow view on this point. Fry, James D., ‘Contextualized legal reviews for the methods and means of warfare: cave combat and international humanitarian law’, in Columbia Journal of Transnational Law, Vol. 44, 2006, p. 453Google Scholar: ‘The phrase “in some or all circumstances” [in Article 36] does not unreasonably oblige states to foresee absolutely all uses of a weapon or method of warfare. However, it does indicate that the commentators are far too passive in interpreting Article 36. Indeed, “in some or all circumstances” suggests that these legal reviews must consider anticipated uses of weapons beyond those that are considered “normal.” … Moreover, … significant changes in anticipated use or use itself calls for repeated review of legality to ensure continued compliance with international law, even after initial deployment of a weapon or method’.
