Normally, terrorist crimes are in one of the 19 universal instruments for combating terrorism. There may also be additional national offences, such as incitement to terrorism, These international instruments, as well as a series of important Security Council resolutions on terrorism (z.B 1267 (1999), 1373 (2001) and 1540 (2004) – are the subject of the review in Module 3, what UNODC commonly refers to as the universal anti-terrorism regime. These instruments also cooperate with other relevant and existing legal obligations of a state, particularly those of international human rights law. As shown in the list of criminal activities above, international instruments are based on most of the currently foreseeable forms of terrorist activity. There is, however, something missing from a special convention on cyberterrorism. (see z.B Fidler, 2016). All broad forms of criminal responsibility (often referred to as inchote, secondary or preparatory offences), such as attempts to conspire, complicity and complicity in acts of terrorism, are generally governed by national law, in accordance with the requirements of the various systems of common and civil law. In developing these broad offences, it is important that States ensure that they are sufficiently close or that there is a causal link with the actual or definitive commission of acts of terrorism, to ensure that local laws are not misused to include non-terrorist activities. The same goes for other types of crimes, such as . B language-related ones (for example. B, incitement, support or apology or terrorism) to preserve fundamental freedoms such as association and expression (see Module 13). These universal instruments create an obligation for States Parties to adopt criminal and procedural material measures to combat various acts of terrorism and, in some cases, administrative measures to combat the financing of terrorism.
Its primary objective is to ensure that criminals have effective mechanisms in place to prevent and repress terrorist acts. These measures are intended to have both preventive and deterrent effects on terrorism. Part of the deterrent aspect of these international instruments is the attempt to harmonize state criminal law and strengthen cooperation in prosecution and criminal justice. At the same time, this is a preventive objective, since effective criminalization of terrorist behaviour by all States should be used to eliminate safe havens for rape of terrorist crimes and to facilitate international cooperation between the authorities involved in the fight against terrorism.
