DRAGOJEVIĆ v. CROATIA JUDGMENT 2 A. Investigation 7. In 2007 the police and the State Attorney’s Office for the Suppression of Corruption and Organised Crime (Ured za suzbijanje korupcije i organiziranog kriminaliteta; hereinafter: “the OSCOC”) investigated allegations of possible drug trafficking between Latin America and Europe via ocean carriers, involving several persons from Croatia. 8. On 23 March 2007, on the basis of a police report, the OSCOC requested an investigating judge of the Zagreb County Court (Županijski sud u Zagrebu) to authorise the use of secret surveillance measures to tap the applicant’s telephone and covertly monitor him. 9. The investigating judge granted the request and on the same day issued an order for the use of secret surveillance measures. Its statement of reasons reads as follows: “On 23 March 2007 the OSCOC lodged a request, no. ..., for secret surveillance measures under Article 180 § 1 (1) and (3) of the Code of Criminal Procedure in respect of Ante Dragojević. The request refers to the [police] report of 2 March 2007, concerning the use of secret surveillance measures in respect of M.R., M.V., B.Ž. and I.B., alleging probable cause to believe that [Ante Dragojević] is also involved in the commission of the offence proscribed by Article 173 §§ 2 and 3 of the Criminal Code. The investigating judge considers that the request is well-founded because the investigation cannot be carried out by other means and the use of these measures in respect of Ante Dragojević is also necessary for satisfactory completion of the investigation, given that there are sufficient grounds for suspecting that he has also been involved in the commission of the offence in issue. It is therefore appropriate to temporarily limit the constitutional rights and decide as above.” 10. In the course of the further investigation the OSCOC learnt that the applicant had been using another telephone number. On 25 May 2007 it asked the investigating judge to extend the use of secret surveillance measures to tap that number. 11. On the same day the investigating judge granted that request and issued an order, which contains the following statement of reasons: “Based on an order of this court under the above number, the secret surveillance measures provided for in Article 180 § 1 (1) and (3) of the Code of Criminal Procedure are being conducted in respect of several persons for the offence proscribed under Article 173 §§ 2 and 3 of the Criminal Code. On 25 May 2007 the OSCOC lodged a request for secret surveillance measures under Article 180 § 1 (1) and (3) of the Code of Criminal Procedure in respect of D.Š., and the secret surveillance measure under [Article 180 § 1] (1) of the above-cited provision in respect of Ante Dragojević, who was using the telephone number ... This measure was also requested in respect of another unidentified person who was using the number ... since the results of the previous use of secret surveillance measures showed that they had made contact in order to commit the offence in issue.
