5.  The applicant was born in 1944. She lives in the village of Katyr‑Yurt, in the Chechen Republic. The applicant is the mother of Magomed-Salekh Ilyasov, born in 1979, and Magomed-Ali Ilyasov, born in 1981. 6.  At the material time the applicant lived with her sons Magomed‑Salekh and Magomed-Ali Ilyasov and other relatives at 25 Sadovaya Street, Katyr-Yurt, in the Achkhoy-Martanovskiy District in the Chechen Republic. The authorities maintained manned checkpoints at the entry and exit points to and from the village, which was under curfew at the material time. 7.  On the night of 12 November 2002 the applicant and her family were sleeping in their house at the above address. At about 4 a.m. two APCs (armoured personnel carriers) and a UAZ vehicle without registration numbers arrived in the applicant’s street. One of the APCs pulled over by the applicant’s gate and the other one by her neighbour’s house. A group of armed men in camouflage uniforms emerged from the vehicles and walked to the applicant’s house. Another group consisting of several armed men blocked the perimeter of the applicant’s house. They took up their positions at intervals, preventing the applicant’s neighbours from getting into the street. 8.  At about 4 a.m. the applicant and L.Sh., her daughter-in-law, got up and went into the kitchen to prepare a meal. They had to cook at night because it was Ramadan. The women were in the kitchen when an armed masked man in a camouflage uniform broke into the room. He neither identified himself nor produced any documents. Pointing his assault rifle at the applicant, he asked in unaccented Russian: “Is anybody here?” and without even listening to the applicant’s reply he went back outside. 9.  The applicant rushed to the room of her son Magomed-Ali. She saw him on the floor, with his hands bound behind his back. He was surrounded by a group of armed masked men in camouflage uniforms. The men spoke Russian without an accent and behaved aggressively. The applicant and her relatives thought that they were Russian servicemen. 10.  At about the same moment five or six servicemen burst into the room where the applicant’s other son, A.I., was sleeping. They pushed him into another room and ordered to furnish his identity papers. When he asked his relatives in Chechen to fetch those documents, the servicemen ordered him in Russian to remain silent and to lie down. The servicemen spoke unaccented Russian. 11.  Shortly thereafter the servicemen took Magomed-Ali to the yard and put him into a shed. The applicant and her daughter-in-law ran outside and started screaming. One of the armed men ordered the applicant to stay quiet and hit her with his rifle butt. The applicant fell to the ground. The applicant’s daughter-in-law asked the servicemen if she could help the applicant to get up. In response one of the officers threatened to shoot the applicant’s daughter-in-law if she did not get back into the house. 12.  The applicant remained in the yard. She got up and saw her second son, Magomed-Salekh, in the yard, surrounded by a large group of the servicemen. His hands were bound behind his back; his head was covered with his T-shirt. The applicant saw an APC parked next to her gate and the other one parked nearby, next to her neighbours’ house. The applicant ran up to Magomed-Salekh and stood up next to him. At this moment she saw the servicemen taking her fourth son, M.I., from the house into the yard. The applicant fainted. 13.  Meanwhile the servicemen took Magomed-Salekh and Magomed‑Ali into the street and put them into the APC at the gate. They let the applicant’s fourth son, M.I., go and told him to calm his mother down. The vehicles drove away towards the centre of Katyr-Yurt. A number of the applicant’s neighbours witnessed the abduction of the applicant’s sons. 14.  After the APCs had driven away, relatives carried the applicant from the yard into the house. On the way there she regained consciousness and saw two servicemen taking away her chainsaw, a bucket of garlic and Magomed-Salekh’s training shoes. The men got into the remaining vehicle and drove away towards the village centre. 15.  The description of the events of the night of 12 November 2002 is based on the following accounts provided to the applicant’s representatives: the applicant’s account, given on 20 August 2007; an account by witness A.I., given on 22 August 2007; an account by witness N.A., given on 20 August 2007, and an account by witness A.P., given on 22 August 2007. 16.  The applicant has had no news of Magomed-Salekh and Magomed‑Ali Ilyasov since 12 November 2002. 17.  The Government submitted that Magomed-Salekh and Magomed-Ali Ilyasov had been abducted on 12 November 2002 by unidentified persons. 18.  Early in the morning of 12 November 2002 the applicant’s relatives complained about the abduction of Magomed-Salekh and Magomed-Ali Ilyasov to E., the head of the village administration. 19.  On the same date the applicant was informed that on the night of 12 November 2002 another resident of Katyr-Yurt had been abducted by the servicemen. She did not remember his name. 20.  On the afternoon of 12 November 2002 E. told the applicant that representatives of a federal agency from Khankala (the main base of the Russian military forces in Chechnya) would visit her house. On the evening of 12 November 2002, a group of Russians and Chechens in civilian clothing arrived at the applicant’s gate in two cars. Without providing any documents or explaining reasons for their actions they conducted a search of the applicant’s house. They did not find anything of interest to them and left. 21.  In the mid-November 2002 the applicant’s relatives were informed that Magomed-Salekh and Magomed-Ali Ilyasov were detained at the Achkhoy-Martanovskiy District Department of the Interior (the ROVD). When at some point later the applicant’s relatives arrived at the ROVD to pass on some food and clothing to the brothers, they were told by the officers that Magomed-Salekh and Magomed-Ali Ilyasov were not detained there. 22.  In the end of November 2002 G., a resident of Achkhoy-Martan who allegedly had some connections in the Federal Security Service (“the FSB”), told the applicant that her sons had been detained in the basement of the ROVD. According to G., the brothers had confessed to unlawful possession of arms. A couple of days later G. informed the applicant that her sons had been transferred to another detention centre and that no information was available about their whereabouts. 23.  In the middle of December 2002 representatives of the prosecutor’s office of the Achkhoy-Martanovskiy district (“the district prosecutor’s office”) arrived at the applicant’s house. They interviewed the applicant, her family members and neighbours and left. 24.  Approximately in the end of January 2003 Ye., an operational-search officer of the ROVD, informed E., the head of the village administration, that after being detained for some time in Khankala, at the main military base of the Russian federal forces in Chechnya, the applicant’s sons had been transferred to the department of the interior of the Staropromyslovskiy district of Grozny (the Staropromyslovskiy ROVD). According to Ye., Magomed-Salekh and Magomed-Ali Ilyasov had been charged with unlawful possession of firearms. Thereafter Ye. told the applicant that she would be able to visit her sons if she managed to obtain a special permit from the military commander of Grozny. The applicant was unable to obtain the permit. 25.  About a week later, in the beginning of February 2003, Ye. informed one of the applicant’s relatives that Magomed-Salekh and Magomed-Ali Ilyasov had been transferred from the Staropromyslovskiy ROVD to a detention centre in Pyatigorsk, in the Stavropol region. No information has been available concerning the whereabouts of the applicant’s sons ever since. 26.  The applicant also contacted, both in person and in writing, various official bodies, such as the Russian President, the Chechen administration, military commanders’ offices and prosecutors’ offices at different levels, describing in detail the circumstances of her sons’ abduction and asking for help in establishing their whereabouts. The applicant retained copies of a number of those letters and submitted them to the Court. An official investigation was opened by the local prosecutor’s office. The relevant information is summarised below.

However, the operational-search measures undertaken by the ROVD had failed to produce any results. 44.  On 25 July 2005 the district prosecutor’s office informed the applicant that on 29 March 2003 the investigation in criminal case no. 44016 had been suspended for failure to establish the identity of the perpetrators. On an unspecified date this decision had been overruled by the supervising prosecutor, who had given the investigator in charge unspecified instructions aimed at solving the crime. 45.  On 5 August 2005 the republican prosecutor’s office forwarded the applicant’s request for assistance in the search for her sons to the district prosecutor’s office for examination. 46.  On 25 August 2005 the investigation in criminal case no. 44016 was suspended for failure to establish the perpetrators. It does not appear that the applicant was informed about the decision. 47.

The applicant requested assistance in her search for her sons. 51.  On 24 December 2005 the republican prosecutor’s office forwarded the applicant’s request for assistance in her search for her sons to the district prosecutor’s office for examination. 52.  On 17 February 2006 the Ministry of the Interior of the Chechen Republic issued an information statement. According to the document, Magomed-Salekh and Magomed-Ali Ilyasov were not on the authorities’ wanted list, nor were they wanted on suspicion of committing a crime. 53.  By a letter of 22 February 2006 the republican prosecutor’s office forwarded the applicant’s request for assistance in her search for her sons to the district prosecutor’s office for examination. 54.

He informed her that the investigation in criminal case no. 44016 had taken the following measures: inspection of the crime scene; drafting a plan of the investigative actions; interviewing more than fifty individuals familiar with Magomed-Salekh and Magomed-Ali Ilyasov; forwarding information requests concerning the whereabouts of the applicant’s sons to law-enforcement agencies and carrying out some other unspecified operational-search measures. According to the document, the supervising prosecutor had issued instructions aimed at solving the crime. The letter stated that on 25 August 2005 the investigation in the criminal case had been suspended; on 11 April 2007 it had been resumed. 61.  On 11 May 2007 the republican prosecutor’s office informed the applicant that her request for information concerning the investigation in criminal case no. 44016 had been forwarded to the district prosecutor’s office for examination. 62.  By a letter of 21 May 2007, in response to the applicant’s request for information about the criminal investigation into her sons’ abduction, the district prosecutor’s office provided her with a response similar to the one of 20 April 2007. In addition, the document stated that the investigation was examining the theory of the possible involvement of those serving in law-enforcement agencies and/or special forces in the abduction of the applicant’s sons, and the theory that the applicant’s sons had been kidnapped for ransom. According to the document, the authorities had no information concerning the possible involvement of the applicant’s sons in any kind of criminal activity. 63.  On an unspecified date the applicant complained to the prosecutor of the Chechen Republic that the investigation in criminal case no. 44016 was ineffective. She requested the authorities to conduct an effective and thorough investigation into her sons’ abduction. In her letter she provided a detailed description of the circumstances in which her sons had been taken away and pointed out that after their abduction Magomed-Salekh and Magomed-Ali Ilyasov had been detained in Khankala and in the Staropromyslovskiy ROVD. It is unclear whether the applicant received any response to this complaint. 64.  The information and documents submitted by the Government may be summarised as follows. 65.  On 25 January 2003 the head of the ROVD replied to the district prosecutor’s office that it had received their letter of 19 January 2003 concerning the disappearance of Magomed-Salekh and Magomed-Ali Ilyasov. The letter of the head of the ROVD further stated that on 25 January 2003 the ROVD had opened an operational-search file no. 000006, in connection with the disappearance of the Ilyasov brothers and that they were forwarding the file to the district prosecutor’s office. 66.  On 29 January 2003 the district prosecutor’s office instituted an investigation into the abduction of Magomed-Salekh and Magomed-Ali Ilyasov under Article 126 § 2 of the Criminal Code (aggravated kidnapping). The decision stated that the applicant’s complaints and the materials in operational-search file no. 000006 contained information that at about 4 a.m. on 12 November 2002 unidentified masked and armed persons in camouflage uniforms, who were driving two APCs and a grey UAZ vehicle, had abducted Magomed-Salekh and Magomed-Ali Ilyasov and taken them to an unknown destination. The case file was given the number 44016. 67.  On 29 January 2003 an investigator of the district prosecutor’s office inspected the crime scene. No information relevant to the investigation was discovered and no items were seized. 68.  On 30 January 2003 an investigator of the district prosecutor’s office granted the applicant victim status in the proceedings in case no. 44016 and interviewed her. The applicant stated that at about 4 a.m. on 12 November 2002, while she and her daughter-in-law were cooking a meal for the Ramadan holiday, a group of armed masked men in camouflage uniforms had broken into the applicant’s house. When the applicant went into the yard, she saw Magomed-Salekh and Magomed-Ali Ilyasov standing under the shed, handcuffed and surrounded by armed men. The servicemen had put Magomed-Salekh and Magomed-Ali Ilyasov into two APCs and a grey UAZ vehicle without registration plates, which were parked at the gate, and taken them away. The applicant confirmed her statement at an interview on 12 April 2007. 69.  On 1 February 2003 the investigator interviewed as a witness L.Sh., the applicant’s daughter-in-law. She stated that at about 4 a.m. on 12 November 2002, while she was in the kitchen with the applicant, a group of armed masked men in camouflage uniforms burst into the house, pointing their guns at them. When the armed men went out into the yard, L.Sh. and the applicant followed them and saw Magomed-Ali Ilyasov standing by a shed with his hands tied behind his back. Shortly thereafter the armed men took Magomed-Salekh, handcuffed, into the shed. The armed men then put the brothers into two APCs and a UAZ vehicle at the gate and drove away. They took the brothers’ passports with them. The abductors had wanted to take the applicant’s other son, M.I., with them but changed their minds and let him go. On the morning of 12 November 2002 the Ilyasovs had alerted the local administration to the abduction of their relatives and the administration officials had immediately put on notice the ROVD and other law-enforcement agencies. Interviewed as a victim on 7 February 2003, L.Sh. confirmed her previous statement. 70.  On 1 February 2003 the investigator interviewed as a witness the applicant’s other daughter-in-law, Z.I. According to her interview record, at about 4 a.m. on 12 November 2002 the applicant had woken her up to cook. Through a window Z.I. had seen two APCs and an UAZ vehicle outside the applicant’s house. Suddenly a group of armed masked men burst in. They pointed their guns at her. When Z.I. went into the next room she saw the armed men handcuff Magomed-Salekh and take him outside. 71.  On 3 February 2003 the investigation interviewed as a witness L.A., the deputy head of the local administration. He stated that early in the morning of 12 November 2002 relatives of the Ilyasov brothers had arrived at his office and told him that Magomed-Salekh and Magomed-Ali Ilyasov had been abducted by armed masked men in camouflage uniforms, who had arrived in two APCs and a grey UAZ vehicle. L.A. immediately alerted the ROVD and the head of the local administration to the abduction, requesting the ROVD to take all necessary steps. 72.  I.Z., an officer of the ROVD, interviewed as a witness on 3 February 2003, stated that on the morning of 12 November 2002 he had learnt from his neighbours about the abduction of Magomed-Salekh and Magomed-Ali Ilyasov. I.Z. had immediately reported the incident to the ROVD and other law-enforcement authorities. 73.  Between 5 and 27 February 2003 the investigation interviewed as witnesses the applicant’s neighbours A.M., M.U., R.M., Kh.Kh., M.T., B.I. and G.B., residing at Sadovaya Street, Katyr-Yurt. Those persons stated that at about 4 a.m. on 12 November 2002 they had been woken up by the noise of several vehicles moving on the street. Having looked outside, they had seen two APCs and a grey UAZ vehicle without registration numbers, parked at the applicant’s house. A group of armed men in camouflage uniforms and masks stayed with the APCs and another group moved to the applicant’s yard. In total there were about fifteen to twenty armed men. After a while shouting was heard from the applicant’s house and the witnesses saw the armed men take the Ilyasov brothers outside, put them into the vehicles and leave with them to an unknown destination. 74.  On 12 February 2003 the district prosecutor’s office requested the heads of remand centres in Vladikavkaz, Makhachkala, Chernokozovo, Stavropol, Nalchik and Pyatigorsk to inform it whether Magomed-Salekh and Magomed-Ali Ilyasov had been held in those detention facilities as from 12 November 2002. 75.  On 14 February 2003 the district prosecutor’s office requested all town and district prosecutor’s offices of the Chechen Republic to inform it whether law-enforcement authorities within the areas under their responsibility had arrested Magomed-Salekh and Magomed-Ali Ilyasov and if so, where the brothers had been detained. On the same date the district prosecutor’s office addressed similar requests for information to the military prosecutor of military unit no. 20102, the deputy head and the military prosecutor of the United Group Alignment (UGA) and the head of the ROVD. The latter body was also instructed to inspect the checkpoint located in the vicinity of the village of Davydenko and to identify the vehicles which had passed through it. All the above-mentioned letters stated that the Ilyasov brothers had been abducted on 12 November 2002 by a group of armed masked men in camouflage uniforms, who had arrived in two APCs and a grey UAZ-452 31010 vehicle without registration numbers. 76.  On 15 February 2003 the district prosecutor’s office requested the military commander of the village of Bamut, the Federal Security Service (“the FSB”) Department in the Achkhoy-Martanovskiy District and the head of the ROVD to inform it whether those authorities had carried out special operations in Katyr-Yurt on 12 November 2002 or whether they had compromising material (“компрометирующий материал”) on Magomed‑Salekh and Magomed-Ali Ilyasov. 77.  Between 27 February and 18 April 2003 the authorities mentioned in paragraphs 74-76 above reported to the district prosecutor’s office that the law-enforcement authorities had not arrested the Magomed-Salekh and Magomed-Ali Ilyasov; that the brothers had not been detained in their detention facilities and that they had no compromising material on them and no information on their whereabouts. 78.  By a letter of 4 March 2003 the ROVD informed the district prosecutor’s office that they had interviewed unspecified servicemen of checkpoints nos. 186 and 187, who had been on duty on the night of 12 November 2002. The letter further stated that “the check had established that no vehicles had passed”. 79.  On 18 April 2003 the military prosecutor’s office of military unit no. 20102 informed the district prosecutor’s office that in order to obtain information on special operations in Katyr-Yurt carried out on 12 November 2002 the latter body had to apply to the military prosecutor’s office of Rostov-on-Don with a request to inspect their archives, because the UGA in the Chechen Republic was keeping the documentation regarding the special operations only within a month after those operations had been carried out and after the expiry of that period of time all related documentation was being sent to the archives of the relevant law-enforcement authorities (the Ministry of Defence, the Ministry of the Interior etc.) in Rostov-on-Don. There is no indication that the district prosecutor’s office applied to the above-mentioned authorities with a view to obtaining that information. 80.  Between 29 July and 21 August 2005 the district prosecutor’s office interviewed as witnesses A.B., S.B., A.M., Ya.Kh., A.D., T.Sh., A.G., A.Ga., A.Kh., M.G., I.I., M.A. and I.G., residents of Katyr-Yurt. According to copies of their interview records and in so far as they are legible, those witnesses had learnt from their neighbours, fellow villagers or the applicant and her relatives that at about 4 a.m. on 12 November 2002 a group of armed masked men in camouflage uniforms had broken into the applicant’s house and had abducted Magomed-Salekh and Magomed-Ali Ilyasov. The abductors spoke unaccented Russian and were driving two APCs and a grey UAZ vehicle without registration numbers. 81.  Following the district prosecutor’s office’ requests for information made on unspecified dates in July and August 2005, several district departments of the interior and heads of remand centres in the Chechen Republic informed it that they had no information about any special operations conducted by law-enforcement authorities within the area of their responsibility and that the Ilyasov brothers had not been arrested or detained. 82.  On 15 April 2007 the district prosecutor’s office requested the temporary operational group of the Ministry of the Interior in Khankala, the Ministry of the Interior of the Chechen Republic, the operational-search bureau in Grozny and the FSB Department in the Chechen Republic to inform it whether they had arrested the Ilyasov brothers or had incriminating material on them. According to the replies of those authorities, their officers had not arrested Magomed-Salekh and Magomed‑Ali Ilyasov and had no incriminating material concerning them. 83.  On 21 June 2008 investigators of the district prosecutor’s office interviewed as witnesses R.Sh. and M.Ch., police officers of the ROVD. They stated that at about 4 a.m. on 12 November 2002 unidentified armed masked persons in camouflage uniforms, who spoke unaccented Russian, had arrived at the applicant’s house in two APCs and a grey UAZ vehicle without registration numbers and had abducted Magomed-Salekh and Magomed-Ali Ilyasov, whose whereabouts remained unknown. 84.  Despite specific requests by the Court the Government did not disclose most of the contents of criminal case no. 44016, providing only copies of the decision to institute the investigation, witness interview records and requests for information and replies to them, summarised in paragraphs 65-83 above. The Government stated that the investigation was in progress and that disclosure of the documents would be in violation of Article 161 of the Code of Criminal Procedure, since it would breach the rights of unspecified participants to the criminal proceedings. 85.  On 24 January 2006 the applicant brought an action with the Achkhoy-Martanovskiy District Court seeking to have her sons Magomed‑Salekh Ilyasov and Magomed-Ali Ilyasov declared missing persons. 86.  By a judgment of 31 March 2006 the court granted her claim and declared the applicant’s sons missing persons as of 12 November 2002.
