5.  The applicant in application no. 30613/05 is Mr Rizvan Dubayev, born in 1955 (the first applicant). The applicant in application no. 30615/05 is Ms Saudat Bersnukayeva, born in 1949 (the second applicant). Both applicants live in the town of Urus-Martan, Chechnya. 6.  The first applicant is the father of Islam Dubayev, born in 1982. The second applicant is the mother of Roman (also known as Zelimkhan) Bersnukayev (also spelled Bersunkayev), born in 1983. 7.  The applicants were not eye-witnesses to the abduction and the following account is based on the witness statements collected by them after the disappearance of their relatives. 8.  In the autumn of 1999 Russian federal troops launched an antiterrorist operation in Chechnya. In December 1999 Islam Dubayev joined an illegal armed group (“the armed group”) which was fighting the federal troops in the mountains of the Urus-Martan district, in the vicinity of the village of Martan-Chu. In December 1999 the Russian federal forces took control of the valley of the Urus-Martan district. 9.  It appears that around the same time Roman Bersnukayev also joined an armed group. 10.  On 13 March 2000 three members of an armed group, Mr A., Mr M. and Mr P., left the mountains to go to the village of Martan-Chu. It appears that on the outskirts of the settlement they were stopped at the Russian military checkpoint by military servicemen from infantry regiment no. 245 of the Russian Federal Forces Group “West” (245 мотострелковый полк группировки федеральных сил «Запад»). The servicemen were assisted by the local militia. The three men were detained and questioned. The military servicemen told them that the State Duma of the Russian Federation had announced an amnesty for those who gave up fighting with armed groups in Chechnya. They assured them that the amnesty would apply to any fighter as long as he had not been involved in serious crimes, such as hostage taking or kidnapping and he voluntarily surrendered to the authorities. The three men then confessed to being members of an armed group. They told the Russian servicemen that there were more young men in the mountains who would be willing to surrender under the above conditions and explained where those men could be found. 11.  It appears that after the questioning Mr A., Mr M. and Mr P. were taken away in an unknown direction and their whereabouts have not been established since. 12.  On 14 March 2000 two members of the Martan-Chu militia went into the mountains and found a group of young men. They told them about the amnesty. They also told the group that if by 3 p.m. on 14 March 2000 they did not come down from the mountains the area would be subjected to artillery and air strikes. 13.  Ten young men decided to surrender. They left the mountains and went to the checkpoint of infantry regiment no. 245. Among them were Islam Dubayev and Roman Bersnukayev. 14.  It appears that on the outskirts of Martan-Chu the men who had surrendered were given food. About twenty minutes later the servicemen bound their hands, put them into a Ural truck and took them to the headquarters of the Russian Federal Forces Group “West”. 15.  On 17 March 2000 the military commander of the Urus-Martan district, General-Major N., and the head of the Federal Security Service (FSB) department of the Urus-Martan district, Major F., co-signed two documents, issued to Islam Dubayev and Roman Bersnukayev. Each document stated that the person in question had voluntarily surrendered his weapons to the State authorities on 14 March 2000 and that he undertook to remain at his place of residence for the follow-up to the amnesty procedure. The document issued to Islam Dubayev mentioned a Kalashnikov machine‑gun without serial number, and the document issued to Roman Bersnukayev mentioned a Kalashnikov machine-gun with a serial number and ammunition. Both papers were countersigned by the applicants' sons. 16.  Also on 17 March 2000 the investigator of the Urus-Martan FSB department issued two decisions certifying the intention of the authorities not to institute criminal proceedings against Islam Dubayev and Roman Bersnukayev, in application of the amnesty act. On the same day both decisions were approved by the acting district prosecutor and countersigned by the two men. 17.  The above description of the events relating to the detention is based on the accounts provided by the applicants to their representatives. 18.  The applicants have had no news of Islam Dubayev and Roman Bersnukayev since 17 March 2000. 19.  The Government stressed that the applicants had not witnessed the detention of their sons. According to their submissions, Islam Dubayev and Roman Bersnukayev had renounced their involvement in the armed groups and on 17 March 2000 were released in application of the amnesty act. There were no grounds to suspect that they had ever been arrested or detained by State authorities. 20.  Since 14 March 2000 the applicants have repeatedly applied in person and in writing to various public bodies. They have been supported in their efforts by the NGO Memorial. In their letters to the authorities the applicants referred to their sons' detention and asked for assistance and details of the investigation. Mostly these enquiries have remained unanswered, or purely formal replies have been given stating that the applicants' requests have been forwarded to various prosecutors' offices. The applicants submitted some of the letters and the authorities' replies to the Court, which are summarised below.
(a) Search for Islam Dubayev 21.  On the evening of 15 March 2000 a man named “Lema” visited the first applicant's house in Urus-Martan and told him that Islam Dubayev had surrendered to the State authorities. As proof he showed photographs found in the pockets of the applicant's son. The middleman told the first applicant that if he came to the village of Gekhi-Chu he would introduce him to the man who had detained his son. The first applicant got the impression that his son might be released against payment of money. 22.  On the morning of 16 March 2000 the first applicant went to the village of Gekhi-Chu. Military servicemen, under the command of an officer named Sergei, also known as “Lame Sergei” (Khromoy Sergei), arrived on an APC (armoured personnel carrier) at about 11 a.m. Sergei read the names of four fighters who had surrendered and been handed over to the Urus-Martan district department of the FSB. They included Islam Dubayev. 23.  It appears that on 16 March 2000 the first applicant went to the district department of the FSB to obtain information about his son, but to no avail. 24.  It appears that within the next few days the first applicant went to the temporary district department of the interior of the Urus-Martan district (the Urus-Martan VOVD) and to the prosecutor's office of the Urus-Martan district (the district prosecutor's office). The interim district prosecutor told the first applicant that Islam Dubayev had been taken to the district department of the FSB and that on 17 March 2000 the amnesty had been applied to him and he had been released. 25.  On 17 March 2000 the first applicant, his relatives and the relatives of the other men who had surrendered allegedly spent the entire day waiting for their sons at the entrance to the building of the district military commander's office, where the district department of the FSB was also located at the time. 26.  Then on a number of occasions the first applicant tried to visit officials at the district department of the FSB, but they refused to talk to him. At some point the first applicant asked officer V. from another department of the FSB to obtain information about his son at the district department of the FSB. The officer told him that his son and three other men had been pardoned by the State authorities and that they had been released from detention in the area of the local town hospital. The first applicant and his relatives searched the area but could not find any traces of Islam Dubayev. 27.  After that the first applicant went to the district department of the FSB and managed to speak to one of the officers, Mr K., and the deputy head of the department, named Sergey. They advised the first applicant to search for his son in the Urus-Martan district hospital. 28.  The first applicant went to the hospital, where he was told that none of the fighters who had surrendered had been brought there. 29.  In the second half of April 2000 the first applicant met the parents of Roman Bersnukayev, who had just found out that their son had surrendered to the State authorities in March 2000. The first applicant and the second applicant agreed to conduct the search for their sons together. 30.  On 11 May 2000 the first applicant met with the head of the district department of the FSB, major F., who provided the first applicant with copies of the documents issued on 17 March 2000 stating the intention of the authorities not to institute criminal proceedings against Islam Dubayev and certifying that Islam Dubayev had voluntarily surrendered his weapons. The officer suggested to the first applicant that if his son had not returned home then “he must have gone into the mountains again”.
(b) Search for Roman Bersnukayev 31.  At the beginning of April 2000 a resident of Urus-Martan, Mr M., came to the second applicant's house and told her husband that Roman Bersnukayev had been detained by the Russian federal forces on his way from the mountains to Martan-Chu. Mr M. had a list of persons detained by the Russian military, including the name of the second applicant's son. 32.  Some time later the second applicant found out that one of the detained persons, Mr A., had been released. Mr A. told her that at the beginning of March 2000 Roman Bersnukayev had left the Chechen fighters and was on his way home when he ran into a group of young men in the mountains of Martan-Chu. 33.  According to Mr A., Roman Bersnukayev had joined the group and had been with them for about two weeks when in March 2000 two members of the Martan-Chu militia found the group and told them about the amnesty. Roman Bersnukayev had not had any weapons and the two men had told him that the amnesty would apply to him only if he had weapons to surrender. Then Roman Bersnukayev had got hold of a machine gun. After that the young men had left the mountains and surrendered to the Russian military forces at the checkpoint in Martan-Chu. 34.  Mr A. told the second applicant that as her son had dark skin, the Russian military servicemen had taken him for an Arab mercenary and had wanted to execute him. 35.  In April 2000 the second applicant met the parents of Islam Dubayev at the entrance to the district military commander's office. The first applicant told the second applicant that their sons had been in the same group of young men who had surrendered in March 2000. 36.  Since then the first and second applicants have been conducting the search for their sons together. 37.  On 11 May 2000 the second applicant received from the district department of the FSB a copy of the order, dated 17 March 2000, concerning the authorities' intention not to institute criminal proceedings against Roman Bersnukayev. 38.  On an unspecified date the second applicant received a copy of the statement dated 17 March 2000, issued by the district department of the FSB, certifying that Roman Bersnukayev had voluntarily surrendered his weapons.
(c) Investigation into the disappearance 39.  On 3 May 2000 the Chechnya prosecutor's office forwarded the first applicant's complaint concerning his son's disappearance to the Chechnya department of the interior for a search to be organised. 40.  On 8 May 2000 the first applicant's wife and the second applicant complained to the district military commander's office about the disappearance of Islam Dubayev and Roman Bersnukayev. They stated that according to information obtained from two sources, Mr Kh. and Mr A., on 14 March 2000 several persons, including their sons, had voluntarily surrendered to infantry regiment no. 245, and that on 17 March 2000 the authorities had applied amnesty to them. 41.  On 31 May 2000 the first applicant complained to the Urus-Martan VOVD about the disappearance of his son after his release from the district department of the FSB on 18 March 2000. The first applicant asked for his son's name to be put on the list of missing persons and provided a photograph of Islam Dubayev. 42.  On 22 August 2000 the Urus-Martan VOVD informed the first applicant's wife that Islam Dubayev had not been detained by the VOVD. 43.  On 16 November 2000 the second applicant complained to the military prosecutor of the Chechen Republic asking for assistance in the search for Roman Bersnukayev. In her complaint she stated that her son had voluntarily surrendered to the Russian federal forces at the checkpoint of infantry regiment no. 245. She stated that her numerous complaints to the law enforcement agencies had been to no avail. 44.  On 12 December 2000 the interim head of the Chechnya department of the FSB informed the first applicant that on 14 March 2000 Islam Dubayev had voluntarily surrendered to the Russian federal troops and had handed over his AK-74 machine gun with ammunition. Pursuant to Articles 208 and 222 of the Criminal Code and the Russian State Duma's decree of 13 December 1999 “On amnesty to persons who committed socially dangerous acts during the antiterrorist operation in the Northern Caucasus”, Islam Dubayev had been absolved from criminal charges. According to the letter, on 17 March 2000 the district department of the FSB had decided not to institute criminal proceedings against Islam Dubayev. The letter informed the first applicant that the Department had no information concerning his son's whereabouts and that searching for missing persons was the job of the police. 45.  On 20 December 2000 the Chechnya deputy prosecutor forwarded the first applicant's complaint concerning his son's disappearance to the Chechnya department of the FSB. 46.  On 14 January 2001 the second applicant complained to the Prosecutor General. She stated that her son had voluntarily surrendered to the Russian federal forces at the checkpoint of infantry regiment no. 245. She stated that her numerous complaints to the law enforcement agencies about his disappearance had not produced any results. 47.  On 20 April 2001 the Chechnya prosecutor's office informed the second applicant that Roman Bersnukayev had not been listed among the detainees held in detention centres in Chechnya. 48.  On 19 May 2001 the prosecutor's office of the Urus-Martan district (the district prosecutor's office) informed the second applicant that on 15 February 2001 their office had instituted an investigation into the disappearance of Roman Bersnukayev under Article 126 § 1 (kidnapping). They did not specify the criminal case file number. According to the letter, the investigation had been suspended owing to failure to establish the whereabouts of the second applicant's son. 49.  On 28 May 2001 the district prosecutor's office informed the first applicant that on 25 November 2000 they had instituted an investigation into the disappearance of Islam Dubayev under Article 126  § 1 (kidnapping) of the Criminal Code. The office did not specify the criminal case file number. According to the letter, on 25 January 2001 the investigation had been suspended owing to failure to establish the whereabouts of Islam Dubayev. The first applicant was requested to provide the office with a photograph of his son. 50.  On 14 June 2001 the first applicant complained to the Prosecutor General of the Russian Federation about the disappearance of his son. In his letter he stated that his son had been seen on 14 March 2000 at the checkpoint of infantry regiment no. 245; on the same day he had been transferred to the district department of the FSB; according to copies of the documents provided by the authorities, his son had been pardoned by the amnesty act, and the documents concerned had been issued by the heads of the Urus-Martan VOVD, the district department of the FSB and the local prosecutor's office and signed by Islam Dubayev. He further stated that the application of the amnesty act had taken only three days, that after 18 March 2000 his son had disappeared and that all his complaints to various state bodies about the disappearance had been to no avail. 51.  On 11 July 2001 the first applicant complained to the district prosecutor about the disappearance of his son. He pointed out that Islam Dubayev had disappeared after being detained by the district department of the FSB. The first applicant stated that he knew people who could testify that his son had been detained in the district department after the date of his alleged release. 52.  On 12 July 2001 the district prosecutor informed the first applicant that the investigation in criminal case no. 24071 had been reopened. 53.  On 25 July 2001 the second applicant complained to the military prosecutor of the Urus-Martan district asking for assistance in the search for Roman Bersnukayev. In her complaint she stated that her son had voluntarily surrendered to the Russian federal forces at the checkpoint of infantry regiment no. 245 and that she had requested the investigation to forward information requests to detention centres in other regions of the Russian Federation. 54.  On 27 July 2001 both applicants requested the district prosecutor's office to grant them the status of victims in the criminal proceedings instituted in connection with their sons' disappearances. On the same day the first applicant was granted victim status and both applicants were recognised as civil plaintiffs. It is unclear whether at that time the proceedings were conducted together. Later, on 21 November 2001, the second applicant was also recognised as a victim in the proceedings related to her son's abduction. 55.  On 7 September 2001 the military prosecutor's office of the North‑Caucasus military circuit informed the first applicant that his complaint had been forwarded to the military prosecutor's office of military unit no. 20102, based in Khankala, the main military base in Chechnya. 56.  On 26 September 2001 the second applicant requested the district prosecutor's office to question the former head of the district department of the FSB, the former senior investigator of that department and the former military commander of the Urus-Martan district. 57.  On 18 September 2001 the first applicant lodged a complaint with the Urus-Martan district court. He described the circumstances of his son's disappearance, complained about the lack of information from the district department of the FSB and described his search for Islam Dubayev. He requested the court to oblige the State authorities to provide him with information concerning the whereabouts of his son. It is unclear whether the applicant's complaint was examined by the court. 58.  On 24 October 2001 both applicants complained to the Prosecutor General. They described the circumstances of their sons' detention by the Russian military servicemen and complained that their numerous letters and requests to the State authorities had produced no tangible results. They also stated that according to a letter obtained by one of the missing young men's relatives from the district prosecutor's office, Islam Dubayev, Roman Bersnukayev and two other men had been in detention after 17 March 2000 as they had to be taken to a “filtration point” (фильтрационный пункт). The applicants asked the prosecutor to reopen the investigation in the criminal case and question the heads of the local law enforcement agencies, to find out what had happened to the detainees after they had been handed over to the district department of the FSB, where they could have been transferred from that department and where they had been taken for “filtration”. 59.  On 3 June 2003 the district prosecutor's office informed the second applicant that the investigation in criminal case no. 24071 (also referred to in the submitted documents under no. 25028) had been reopened on 3 May 2003. 60.  On 17 July 2003 the district prosecutor's office ordered the Urus‑Martan VOVD to conduct investigative operational search measures in criminal case no. 24071 to identify persons who could have seen Islam Dubayev and Roman Bersnukayev at the Urus-Martan VOVD, at the local military commander's office or at local military checkpoints. 61.  On 14 August 2003 the first applicant complained to the Prosecutor General and to the military prosecutor of the United Group Alliance (UGA). He described the circumstances of his son's disappearance and requested the following measures: reopening of the investigation into the abduction of Islam Dubayev and transfer of the case, if necessary, to the military prosecutor's office for investigation; questioning of the former head of the district department of the FSB and the former district military commander, and establishment of the whereabouts of Islam Dubayev. 62.  On 10 November 2003 the district prosecutor's office informed the second applicant that the investigation in criminal case no. 24071 had been suspended on 31 October 2003 and reopened on 10 November 2003. 63.  On 9 March and 9 April 2004 the first applicant requested the district prosecutor's office to question the former head of the Urus-Martan VOVD. On 11 March 2004 the district prosecutor's office informed the first applicant that the authorities had forwarded a number of information requests to establish the whereabouts of the former head of the Urus-Martan VOVD. 64.  On 30 April 2004 the district prosecutor's office informed the second applicant that the investigation in criminal case no. 25028, opened on 15 February 2001, had been suspended owing to failure to identify the perpetrators. 65.  On 30 May 2004 the district prosecutor's office rejected the applicants' request to question the former head of the Urus-Martan VOVD because they were unable to establish the officer's whereabouts. 66. In June and July 2004 both applicants requested the district prosecutor's office to grant them access to the materials of criminal case no. 24071. 67.  On 19 June and 29 July 2004 the district prosecutor's office informed the first and second applicants that under Article 42 of the Code of Criminal Procedure they were entitled to access to the case file materials only after completion of the criminal investigation. Prior to that, they were entitled only to receive copies of decisions on the opening of criminal proceedings, the granting of victim status and the suspension of the investigation. The applicants were also informed that the investigation in case no. 24071 had been suspended owing to failure to identify the perpetrators. 68.  On 9 September 2004 the district prosecutor's office again informed the applicants that the investigation in criminal case no. 24071 had been suspended owing to failure to identify the perpetrators. 69.  On 3 December 2004 the first applicant again requested the district prosecutor's office to question the former head of the Urus-Martan VOVD. In his request the first applicant pointed out that the officer had been appointed to the post in March 2000 and had come from the department of the interior of the Penza Region. On 4 December 2004 the district prosecutor's office informed the first applicant that his request of 3 December 2004 was granted in full. No further information concerning the questioning has been communicated to the applicant. 70.  On 26 April 2005 the district prosecutor's office reopened the investigation in criminal case no. 24071. 71.  On 6 May 2005 the district prosecutor's office suspended the investigation in criminal case no. 24071 owing to failure to identify the perpetrators. 72.  On 19 December 2005 the applicants complained to the district military commander. In their letters they described in detail the events of 14-17 March 2000 and asked for help in locating their sons. 73.  On 13 February 2006 the first applicant requested the district prosecutor's office to question him as he wanted to provide the investigation with new information. It is not clear from the submitted materials whether the district prosecutor's office conducted the requested questioning. 74.  On 2 June 2006 the second applicant asked the district prosecutor for news of progress in the criminal investigation. She also asked him to explain the delays in the investigation. 75.  The Government submitted 181 pages from criminal investigation file no. 24071. The contents of these documents and the Government's observations can be summarised as follows. 76.  The investigation of the disappearance of Islam Dubayev had commenced on 25 November 2000. The case file was assigned the number 24071. The investigation into Roman Bersnukayev's disappearance was opened on 15 February 2001 and the case file was assigned the number 25028. On 4 February 2002 both cases were joined under no. 24071, but it does not appear that the applicants were ever officially informed of this. 77.  According to the Government, the first applicant was questioned on 28 November 2000, but no copy of the transcript has been submitted. He was granted victim status in the proceedings on 27 July 2001. The second applicant was questioned on 4 February 2001. She was granted victim status on 21 February 2001. According to the Government, the first applicant was additionally questioned eight times in 2001 – 2007. The second applicant was additionally questioned on five occasions. No copies of their testimonies were submitted to the Court. 78.  The investigation questioned some other local residents. On 4 February 2001 one neighbour of the Bersnukayevs' stated that he had not seen Roman for about a year or a year and a half. The witness had heard that Roman Bersnukayev had been killed by unknown men in military uniforms. In September and November 2001 the investigators questioned Roman Bersnukayev's two brothers and father, who all confirmed that they had not seen him since November 1999 and that he had disappeared after surrendering on 14 March 2000 to the 245th infantry regiment. On 7 October 2003 and 20 January 2004 the investigation again questioned Roman Bersnukayev's father. In December 2003 Roman Bersnukayev's sister was questioned. In June 2005 Roman Bersnukayev's aunt stated that she was unaware of his whereabouts since 1999. In May 2007 the investigation questioned Islam Dubayev's brother and sister, who had had no news of him since his surrender in March 2000. 79.  According to the Government, on 1 October 2003 the investigation questioned the first applicant's wife, who stated that certain FSB officers had told her that Islam Dubayev had been released on 17 March 2000. The Government did not provide a copy of that questioning to the Court. 80.  The Government stated in their observations that on 16 January 2001 and on 4 February 2002 the investigation had questioned Mr I.A., the father of A., one of the young men who had been detained together with Islam Dubayev and Ruslan Bersnukayev, who had also disappeared. He confirmed that his son and three other young men had been detained on 14 March 2000 by the military servicemen to whom they had surrendered, and transferred to the local department of the FSB, where an amnesty act has been applied to them on 17 March 2000. After that they had disappeared. The Government did not submit the transcripts of his questioning. 81.  The investigation took some steps to identify and question officials who might be aware of the detainees' fate. On 30 May 2004 the investigator of the district prosecutor's office rejected the first applicant's request to question the former head of the Urus-Martan VOVD, having failed to establish the officer's whereabouts. The order also mentioned that it had proved impossible to find and question other officials who had worked in the district department of the FSB, the military commander's office and the VOVD at the relevant time. 82.  Without providing a copy of the transcript, the Government referred to the questioning of the head of the temporary detention ward of the Urus‑Martan ROVD on 20 January 2004, who had explained that in 2000 criminal suspects had been delivered to the premises of the VOVD. The latter temporary body had been closed in May 2002, after which the usual department of the interior (ROVD) had taken over. He had no information about the missing men. 83.  In August 2003 a former official of the Urus-Martan district administration was questioned and stated that he had no recollection of the applicants' case. In January 2004 the then head of administration of Gekh‑Chu stated that the previous head of administration had been killed by unknown gunmen in 2001. The witness had no information about the applicants' case. On 4 December 2004, following a court ruling to that effect (see below), the investigation asked the Penza regional prosecutor's office to question Ministry of the Interior Colonel Sh. [who had been the head of the Urus-Martan VOVD at the relevant time] about the detention of the two men at the Urus-Martan VOVD on 17 March 2000. On 15 January 2005 Colonel Sh. stated that he did not recall anything relevant to the investigation, that he could not name any other servicemen who had served there at the time and that he was not aware of the whereabouts of the registration logs of the VOVD. 84.  In September 2006 the first applicant asked the investigation to identify and question members of the 245th infantry regiment who had served near Tangi-Chu and might be aware of the subsequent whereabouts of the men who had surrendered. In February 2007 he repeated his request to reopen the proceedings, to identify and question the officials involved and to inform him of the progress made. 85.  In October 2003 both disappeared young men were described by the local police as law-abiding persons who had had no part in any serious crimes during their involvement with extremist groups. 86.  The investigators also requested information about the disappearances from various State authorities. In their letters they stated that “it has been established that on 17 March 2000 Islam Dubayev and Roman Bersnukayev were detained at the Urus-Martan VOVD”. On 11 December 2003 the district department of the FSB stated that their office had not detained Islam Dubayev and Roman Bersnukayev or carried out a criminal investigation into their activities. Their office was also unable to assist with the identification and questioning of eye-witnesses of the arrest and questioning of the two men. A similar reply was received from them in May 2007. In March and April 2006 the district departments of the interior in Chechnya informed the investigation that they had never detained Islam Dubayev and Roman Bersnukayev or delivered them to a temporary detention ward. In March 2001 and in September 2003 the remand centres in the Southern Federal Circuit informed the investigation that the missing men had never been detained there. The district department of the interior reported their lack of findings to the district prosecutor's office in response to their requests on numerous occasions between 2003 and 2007. 87.  According to the documents and information submitted by the Government, between 2001 and 2008 the investigation was suspended and resumed on several occasions, and has so far failed to identify those guilty or to establish the whereabouts of Islam Dubayev and Roman Bersnukayev. 88.  The Government further submitted that the applicants had been duly informed of all decisions taken during the investigation. 89.  Relying on the information obtained from the Prosecutor General's Office, the Government stated that the investigation was in progress and that disclosure of the remaining documents would be in violation of Article 161 of the Code of Criminal Procedure, since the file contained information of a military nature and personal data concerning the witnesses or other participants in the criminal proceedings. 90.  On an unspecified date the first applicant lodged a complaint with the Urus-Martan town court. He complained about the failure of the district prosecutor's office to conduct a thorough and impartial investigation in the criminal case concerning the abduction of his son. 91.  On 7 April 2004 the town court allowed the applicant's complaint and instructed the district prosecutor's office to conduct a thorough and effective investigation in the criminal case. 92.  On an unspecified date in 2004 the first applicant lodged another complaint with the Urus-Martan town court. He complained about the failure of the district prosecutor's office to conduct a thorough and impartial investigation in the criminal case concerning the abduction of his son. In particular, he complained about the failure of the investigation to examine his request of 9 March 2004 concerning the questioning of the former head of the Urus-Martan VOVD and about the lack of access to the criminal case file materials. 93.  On 27 May 2004 the town court allowed the applicant's complaint in part. The court stated that the district prosecutor's office had unlawfully failed to examine the applicant's request of 9 March 2004, and instructed the investigative authorities to conduct a proper examination. It rejected the remainder of his complaints. 94.  The applicant's appeal against the decision of 27 May 2004 was rejected on 3 September 2004 by the Supreme Court of the Chechen Republic. 95.  On 19 October 2004 the first applicant lodged a new complaint with the town court. He complained about the failure of the district prosecutor's office to conduct a proper investigation in the criminal case concerning the abduction of his son. He sought a ruling obliging the authorities to conduct a thorough and effective investigation in the criminal case. 96.  On 11 November 2004 the town court rejected the applicant's complaint. On 16 March 2005 that decision was overruled on appeal and the complaint was remitted for fresh examination. 97.  On 7 April 2005 the district court again reviewed the first applicant's complaint. It concluded that the investigation had failed to take steps to locate and question a number of officials of the FSB and the Ministry of the Interior who had taken part in the proceedings related to the application of the amnesty act in respect of the applicants' sons. By its decision it again required the district prosecutor's office to carry out a complete and effective investigation into the crime. 98.  On 28 March 2007 the district court allowed another complaint by the first applicant and obliged the district prosecutor's office to grant his request, to reopen the adjourned proceedings and to carry out an “effective” investigation. 99.  On an unspecified date the second applicant lodged a complaint with the Urus-Martan town court. She complained about the failure of the district prosecutor's office to conduct a thorough and impartial investigation in the criminal case concerning the abduction of her son. In particular, she complained about the failure of the investigation to examine her request of 26 September 2001 concerning the questioning of a number of witnesses. 100.  On 30 June 2004 the town court allowed the applicant's complaint in part and instructed the district prosecutor's office to conduct a proper examination of the applicant's complaint of 26 September 2001. 101.  An appeal lodged by the applicant against the decision of 30 June 2004 was rejected on 3 September 2004 by the Supreme Court of the Chechen Republic. 102.  Sometime in 2005 the second applicant again lodged a complaint with the town court. She sought a ruling obliging the authorities to conduct a thorough and effective investigation in the criminal case concerning the abduction of her son. 103.  On 3 March 2005 the town court rejected the second applicant's complaint. On 25 May 2005 that decision was upheld on appeal by the Supreme Court of the Chechen Republic.
