Yes, it is possible. Controlled delivery means the monitoring of movement of the consignment from the sender to the addressee during its transit, export or import, if the circumstances of the case justify the assumption that the consignment without the necessary permits contains narcotic substances, psychotropic substances, precursors, poisons, nuclear or other radioactive materials, hazardous chemical substances, counterfeit or altered money, counterfeit or altered securities, counterfeit, altered or illegally produced custom stamps, postal stamps, labels and postal stamps, means of payment, firearms or weapons of mass destruction, ammunition and explosives, cultural heritage items or other items that require special permissions for their possession, items intended to commit a criminal offence, or items of a committed criminal offence, for the purpose of apprehending persons who take part in the handling of such consignment (Section 111 of the Criminal Procedure Code).
A warrant for the controlled delivery must be issued by the presiding judge, before the commencement of the criminal prosecution, or in the preliminary hearing by the public prosecutor. Monitoring of the delivery is performed by the Police Force in cooperation with customs administration authorities, which must be notified of such procedure in advance.
The Police Force may commence the monitoring of the consignment without the warrant if the item cannot be deferred and the warrant cannot be procured in advance. The Police Force shall notify the public prosecutor of such act without undue delay. If the public prosecutor fails to issue a warrant within 48 hours, the monitoring of the consignment must be terminated and the obtained information can no longer be used in further proceedings and must be destroyed in the prescribed manner without undue delay.
The Police Force shall terminate the monitoring of the consignment through the written order of the public prosecutor, and if it is clear that the handling of the consignment creates a serious danger to life or health, significant damage to assets, or if there is a serious risk that it will not be possible to further monitor such consignment, even without the written order. If necessary, together with the termination of the monitoring of a consignment, the Police Force shall take action against the further detention of items that are part of the consignment; this shall not apply if the monitored consignment is in transit across the State border and its monitoring will be assumed by the competent authority of another State within international cooperation.
