Infiltration par les agents de l’Etat requis (201)



Is this measure possible in your Member State under International Judicial Cooperation?

Yes. Covert collection of intelligence refers to short-term interaction with a certain person for the obtaining of information, and in which a police officer in order to conceal the task uses false, misleading or concealed information. Covert activity refers to extended collection of intelligence directed at a certain person or at his or her activity through the use of infiltration, in which false, misleading or concealed information, register notations or documents are used or prepared, in order to achieve the confidence needed for the collection of intelligence or to prevent the revelation of the collection of intelligence. Police officers have a right to undertake undercover activities if they are necessary for preventing, detecting or investigating certain serious criminal activities when there is justifiable cause to suspect that the persons on whom information is collected would commit certain severe offences. In addition the collection of intelligence is to be deemed necessary in view of the degree to which the criminal activity is planned, or in view of anticipated continuity of repetition. Undercover activities in a place of residence are permitted with an occupant's active assistance of entry or stay. Pseudo purchase denotes an offer made by a police officer to buy an object or property that is in someone's unlawful possession, or is the object of trade, in order to prevent or detect the possession, trade or illegal preparation of such objects or property or to locate them, or to recover proceeds from crime. A police officer has a right to make a pseudo purchase if there is an intention to take the substance into the possession of the police, or finding evidence in criminal matters or pseudo purchase could otherwise be of assistance in clarification of a criminal matter. In addition the pseudo purchase must be necessary in an investigation of certain offences and it shall not be committed in a way that induces the subject of the measure or another person to commit an offence that he or she would otherwise not commit. A pseudo purchase in a place of residence is only allowed if there is active co-operation of the person using the residence.
