19. 专家组审议了是否应建议拟订一项具体处理非法制造和贩运爆炸物的国际文书问题。一致认为研究结果表明发生的具有跨国性质的事件较少，但也注意到事件可能报告得不充分，应考虑到个别事件的潜在严重性，即使这类事件较少发生。一些专家认为，虽然研究表明发生了一些跨国活动，考虑到国际社会所面临的其他问题和优先事项，上述活动在程度、频率或严重性方面都不足以因此而花费大量时间、费用和努力来制订一项文书。有些专家还认为，鉴于在诸如爆炸物标识等方面的技术和法律发展情况，任何文书都不应具有法律约束性。另一些专家指出，现有的国际文书中还没有处理这一问题各个方面的。这些专家认为，考虑到一些国家所遇到的严重问题，以及个别尽管并不经常发生的事件对人的生命和安全构成严重威胁的事实，制订一项国际法律文书是必要的。
19. The Group of Experts considered the question whether an international instrument dealing speci-fically with the illicit manufacturing of and trafficking in explosives should be recommended. There was agreement that the results of the study suggested that relatively few incidents of a transnational nature occurred, but it was also noted that incidents were likely to be underreported, and that the potential seriousness of individual incidents should be taken into consideration, even if they occurred relatively infrequently. Some experts were of the view that, while the research suggested some transnational activities, they were not sufficient in extent, frequency or seriousness to warrant the time, costs and efforts required to produce an instrument, having regard to other issues and priorities confronting the international community. Some also expressed the view that, given the state of technical and legal developments in areas such as the marking of explosives, any instrument should not be of a legally binding nature. Other experts noted that none of the existing international instruments dealt with the problem in all of its aspects. Those experts were of the view that an international legal instrument was desirable, having regard to the serious problems encountered by some States and the fact that individual incidents, even if infrequent, could represent serious threats to human life and security.
