The Committee of Experts on Terrorism (CODEXTER) was an intergovernmental body coordinating the Council of Europe's action against terrorism. It drafted the Council of Europe Convention on the Prevention of Terrorism and a number of important soft law instruments.

Committee of Experts on Terrorism (CODEXTER)

CODEXTER was focusing on:

  • terrorism and the internet;
  • radicalisation leading to terrorism and receiving of training for terrorism, including via the Internet;
  • special investigation techniques;
  • assessment of possible gaps in the legal framework provided by the Council of Europe international legal instruments in the area of the prevention and suppression of terrorism, including with respect to Interantional Humanitarian Law and terrorism and also in relation to the absence of a common definition of 'terrorism' in International law
  • links between terrosim and organised crime (to be addressed in cooperation with the CDPC).

Other work of CODEXTER included country profiles on legislative and institutional counter-terrorism capacity, monitoring the signatures and ratifications and promoting the effective implementation of the Council of Europe instruments applicable to the fight against terrorism, in particular the Convention on the Prevention of Terrorism (CETS No.196), exchange of best practices of combating terrorism while fully respecting human rights and the rule of law, and preparation of the database of the European Court on Human Rights cases related to counter-terrorism.

CODEXTER worked in close cooperation with international bodies, such as the United Nations Counter-Terrorism Committee Executive Directorate (CTED), the United Nations Office on Drugs and Crime (UNODC), the Organisation for Security and Cooperation in Europe (OSCE), the European Union, and the Global Counter-Terrorism Forum.

In 2018 CODEXTER became the Council of Europe Counter-Terrorism Committee (CDCT).
