One of the international community’s strongest instruments to prevent terrorism is a coherent legislative framework that as many countries as possible in the world adhere to.

We support Member States with the implementation of the international legal framework against terrorism. This includes 19 international legal instruments and relevant United Nations Security Council resolutions. These legally-binding instruments relate to for example the hijacking of airplanes; hostage-taking of internationally protected persons; illicit use or handling of chemical, biological, radiological or nuclear materials; acts against the safety of maritime navigation or fixed platforms on the continental shelf; bombings; and financing of related terrorist incidents.

The implementation of these instruments is guided by the UN Global Counter-Terrorism Strategy and by resolutions of the UN General Assembly.


We conduct legislative assessments and gaps analyses of existing national counter-terrorism legislation, upon request. We also assist with the drafting and revision of legislation to harmonize Member States’ national legislation and align it with the international legal instruments against terrorism.

We maintain the SHERLOC knowledge management portal, which contains databases on the status of adherence to the 19 international legal instruments against terrorism. It also contains extensive information on national counter-terrorism legislation and on relevant case law relating to terrorism and other crime areas.


Since its establishment in 2003, we have assisted Member States with the development of counter-terrorism legislation. Since then, we have recorded 1,145 new adherences to the universal legal instruments against terrorism.
