9.  The applicants (see paragraph 1), who were born in 1955, 1975, 1977, 1979, 1981, 1985, and 1988 respectively, are the wife and children of the deceased, Cavit Özalp, who was killed in 1995 while he was under custody.
Events concerning the death of Cavit Özalp 10.  Until 1994, the Özalp family resided in the Serçeler village in Bismil District in province of Diyarbakır. When the security forces started to pressurise the Özalp family members to become village guards, the family moved to Diyarbakır in the spring of 1994. 11.  On 21 August 1995 one of the applicants, Mr Hacı Özalp, went back to Bismil to visit the fields that belonged to his family. When he arrived in Bismil, he was stopped by soldiers and questioned about his father, Cavit Özalp. He was subsequently taken to the gendarme command, where he was further questioned about his father. During the interrogation, Hacı told them where they could find Cavit Özalp. 12.  On 24 August 1995 Cavit Özalp was taken into custody in Diyarbakır. On the same day, Hacı saw his father in custody however he was not allowed to speak to him. 13.  On 26 August 1995 Hacı was released from custody. On the same day, while he was still in Bismil, he was informed by an acquaintance that an incident had taken place in the Kamberli village and that it concerned his father. Consequently, when Hacı went to the Kamberli village to find out more about this incident, he met a villager, called Vehyettin, who told him that his father was dead. 14.  On the same day two police officers visited Cavit's house in Diyarbakır and told Hacı's uncle that Cavit had died. 15.  On 5 February 1996 the applicants' representatives filed a petition with the public prosecutor attached to the Diyarbakır State Security Court. Referring to the investigation that had been commenced into the death of Cavit Özalp and the decision of non-prosecution that had been delivered by the Diyarbakır State Security Court public prosecutor, the applicants' representatives requested a copy of the arrest and autopsy reports as well as the public prosecutor's decision of non-prosecution. 16.  The public prosecutor refused to give these documents and noted at the bottom of the petition the following:
“It has been decided [by this office] that no prosecution should be brought about the death of Cevat Özalp [Note: Cavit's name is spelled out as Cevat in the public prosecutor's note.] pursuant to Article 96 of the Turkish Criminal Code. The investigations in order to apprehend the co-activists of Cevat Özalp are still ongoing. A copy of the investigation file could not have been given [to the representatives] in accordance with the relevant provisions of the Constitution, as it would constitute disclosure of the content and the subject matter of the investigation file.” 17.  On 24 August 1995 Cavit Özalp was taken into custody by the gendarmes from the Bismil Gendarme District Command on suspicion of membership of the PKK, proscribed as a terrorist organisation. He was suspected of aiding and abetting the PKK terrorists. 18.  On an unspecified date Cavit Özalp gave a statement to the gendarmes. He stated that the PKK terrorists were occasionally staying in his house and that he was providing them with food and military equipment such as weapons, clothes and medicine. He further stated that he had dug a shelter with the terrorists on the slopes of a hill near the Pamuk River in the Sarıhüseyin hamlet attached to the Serçeler village to hide some equipment. 19.  On 24 August 1995 Cavit Özalp was taken to the Bismil Health Center for medical examination. According to the medical report, there were no signs of ill-treatment on his body. 20.  On 26 August 1995 at 4 a.m. the gendarmes conducted a search to find out the location of the shelter that had been mentioned by Cavit Özalp in his statement. Cavit guided the soldiers to the shelter near the Şedat road in the Kamberli village. While protecting themselves in a secure distance, the soldiers asked him to open the cover of the shelter. As he opened the cover, the soldiers witnessed a big explosion, which tore Cavit's body into pieces. The explosives had been placed in the entrance to the shelter by other members of the PKK and the soldiers found weapons, medical equipment and clothes in the shelter. The incident was further reported to the Bismil public prosecutor. 21.  On the same day an on-site examination was conducted by the Bismil public prosecutor together with a doctor. According to an onsite body examination, it was established that both legs were severed as a result of the explosion. No other signs of injury were observed on the dismembered body. The doctor decided that it was unnecessary to conduct a full autopsy on the body. Cavit's corpse was then given to Mr Hasip Yılmaz, a member of the Kamberli village assembly. An incident report was further drafted by the gendarmes and was signed by three non-commissioned officers and the village mayor Mr Kütbettin Altunç. 22.  On 24 November 1995 the public prosecutor at the Diyarbakır State Security Court decided that no prosecution should be brought against Cavit Özalp on account of his membership of the PKK on the ground that he had died on 26 August 1995. 23.  On 14 November 1995 the Bismil public prosecutor accused the non-commissioned officer, Mr İlhan Yücel, of failing to take the necessary precautions when Cavit Özalp had been asked to open the cover of the shelter and of causing Cavit Özalp's death through negligence. However, as the public prosecutor did not have the jurisdiction to bring proceedings against the non-commissioned officer, he declared lack of jurisdiction and transferred the case file to the Bismil District Administrative Council. 24.  Subsequently, the District Administrative Council appointed a major as a rapporteur to conduct further investigations into the killing of Cavit Özalp. On 15 January 1996 the major took statements from the non-commissioned officers, Mr İlhan Yücel, Mr Yılmaz Öztiryaki and Mr Ömer Karabaş, who had been on site during the incident of 26 August 1995. The officers stated that Cavit Özalp had been taken into custody on suspicion of membership of the PKK and had confessed that he had been aiding and abetting the terrorists, providing them with food, clothes, weapons and medical equipment. The soldiers further stated that Cavit had mentioned a shelter which was used by the terrorists and when he was taken to the site to show the place of the shelter, the gendarmes had positioned themselves far from the shelter to prevent any loss of life. The soldiers explained that Cavit was asked to open the shelter, however he had died as a result of the explosion. The officers finally stated that medical equipment and clothes had been found in the shelter. 25.  Basing himself on the statements of the three accused non-commissioned soldiers, the incident and the body examination reports, on 23 January 1996 the rapporteur submitted his report to the District Administrative Council. He concluded that the security forces had taken all the necessary precautions before Cavit Özalp was asked to open the cover of the shelter. The report further stated:
“Having regard to the fact that Cavit Özalp had confessed that he had dug a shelter [with the other terrorists] it was presumed that he could have known the place of the shelter and that he could have safely opened its cover himself. After the necessary safety measures had been taken, he had been asked to open the cover. However, he had died in an explosion. The explosives had been previously placed there by the terrorists. Neither the security forces nor Cavit Özalp had noticed the explosives.” 26.  The report concluded that the security forces had performed their duty with diligence and it was recommended that no prosecution be brought against the members of the security forces. 27.  On 28 February 1996 the Bismil District Administrative Council issued a decision stating that no prosecution should be brought against the members of the security forces. The council concluded that Cavit Özalp had died as a result of the explosion and that the accused members of the security forces had performed their duty with diligence. 28.  On 2 April 1996 the Diyarbakır Regional Administrative Court, to which the case had been automatically referred to by law, upheld the decision of the Bismil District Administrative Council. 3.
