Questionnaire in pdf format


The purpose of this questionnaire is to gather information about the situation in member States concerning Special Investigation Techniques (SITs), their regulation and use.

The information gathered through this questionnaire is intended to serve the purpose of implementing the terms of reference of the PC-TI which are “to study the use of special investigation techniques respective of European criminal justice and human rights standards, with a view to facilitating the prosecution of terrorist offences and increasing the effectiveness of law enforcement, and to make proposals as to the feasibility of preparing an appropriate instrument in this field.”1 2

For the purposes of this activity, SITs are tentatively defined as techniques for gathering information systematically in such a way as not to alert the target person(s), applied by law enforcement officials for the purpose of detecting and investigating crimes and suspects.3

This questionnaire deals inter alia with the following SITs4:

Delegations are invited to provide information about other SITs used in their country.

The questionnaire does not directly concern the means for carrying out the SITs. However, delegations are invited to provide information about them where appropriate.


1. Please indicate the SITs used in your country, the respective legal framework governing their use and their legal definition, if any.
2. When and under which circumstances (eg criminal investigation, preliminary stage, etc) SITs can be used?
3. Are there any specific features governing the use of SITs in relation to acts of terrorism? If so, please specify.
4. How does the legal framework governing the use of SITs guarantee respect for human rights and individual freedoms, the principles of subsidiarity and proportionality? Is the authorisation to use SITs subject to time-limits? Which bodies and procedures are in place to supervise compliance with human rights standards and with the above-mentioned principles in the use of SITs? Is supervision automatic/systematic?
5. Which institutions are involved in the use of SITs and what is their role (e.g. law enforcement agencies, prosecutor’s Office, judicial authorities, etc)? Which institutions can order and/or authorise the use of SITs? How does co-operation between these institutions work in practice ?
6. Are there any specialised counter-terrorism institutions? What is their role in the use of SITs.
7. Which measures have been adopted in order to facilitate international co-operation (e.g. joint investigation teams)? Can the SITs listed in reply to question 1 be used in cross-border settings?
8. What use can be made of SIT in the context of mutual legal assistance?
9. How can the use of SITs be improved? Please provide any comments/proposals concerning the implementation of the terms of reference of the PC-TI and in particular the use and regulation of SITs.
