Yes, it is. Generally, it is the measure used in Police-to-Police cooperation. However, due to the Polish implementation of the EIO Directive it can be implemented within the framework of judicial cooperation. According to the Article 589w § 7 of the CPC, where operational and exploratory activities are carried out on the basis of separate regulations (e.g. law on the Police), an EIO shall be issued by the body carrying out such activities after prior consultation with the relevant body of the ruling enforcement state as to the duration of those activities and the conditions for their performance. The issuance of an EIO shall require approval by the public prosecutor competent on the basis of separate regulations, unless the admission, obtaining or examination of evidence is reserved to the competence of the court. In such a case, the issuance of an EIO shall require approval by the court competent on the basis of separate regulations. Additionally, according to the Article 589zi § 6 of the CPC, If an EIO includes a request to carry out operational and exploratory activities, the competent Polish services and the competent services of the ruling issuing state shall agree on the duration of the activities and the conditions for their performance within the scope of that request.
