5.  The applicant was born in 1959 and lives in Ovchepoltsi. 6.  On the evening of 1 May 1991 the applicant was involved in a fight between several people in the village of Ovchepoltsi. During the fight he was stabbed with a knife in the stomach. Some members of the public came to his aid and took him to hospital. 7.  On the same day the applicant was admitted as an in-patient, and underwent an urgent operation. He was discharged on 13 May 1991 and was given thirty days’ sick leave. 8.  On 1 May 1991 the investigating authorities inspected the site where the fight had taken place. They took photos and seized a wooden stick stained with blood. 9.  On 1 and 2 May 1991 several witnesses were questioned. 10.  On 2 May 1991 criminal proceedings were opened against two of the participants in the fight: T.S. and P.S. They were charged with attempted murder and questioned. 11.  On 12 May 1992 the case investigator commissioned a medical expert report to establish the extent of the victim’s injuries. The report relied on the medical records from the applicant’s stay in hospital and established that he had suffered a 3 cm knife wound in the abdominal cavity which resulted in an injury to the great omentum and to the large intestine. The applicant had also suffered a combination of other injuries: large bruises on the face and on the right leg, and a broken rib. 12.  Between 18 May and 8 June 1992 several witnesses were questioned. 13.  It appears that between 1991 and 1994 the applicant’s mother wrote several times to the prosecuting authorities, complaining of inactivity on the part of the investigator in charge of the case. In response, the supervising prosecutor wrote to the investigator on several occasions requesting that the investigation be completed; for example in a letter of 19 August 1994 the prosecutor requested that the investigation be completed “without delay”. 14.  On 17 June 1996 the attempted murder charge against T.S. was changed to a charge of having caused intermediate bodily harm and he was questioned in this connection. 15.  On 11 September 1996 the attempted murder charge against P.S. was also changed to a charge of having caused intermediate bodily harm and he too was questioned. 16.  Between 25 August 2000 and 1 July 2002 some of the witnesses were recalled for further questioning. 17.  On 18 July 2003, following a complaint by the applicant’s lawyer in relation to the length of the investigation and inactivity on the part of the investigator in charge of the case, the supervising prosecutor removed the investigator and gave instructions to the investigating authorities to commission a new medical expert report and to conclude the investigation within thirty days. The Court has not been informed by either party of what substantive investigative steps, if any, were undertaken after that date. 18.  On 5 June 2006 the public prosecutor terminated the proceedings on the ground that the relevant statutory limitation period for bringing a prosecution had lapsed. 19.  On 13 July 2006 the applicant appealed against the order terminating the proceedings. In a decision of 17 July 2006 the Pazardzhik Regional Court (“the Regional Court”) ruled that the assailants remained charged with attempted murder and therefore the statutory limitation period for prosecution had not lapsed. The court remitted the case to the prosecutor’s office, instructing it to continue with the investigation. 20.  T.S. and P.S. appealed against the decision of the Regional Court. In a final decision of 27 September 2006 the Plovdiv Court of Appeal ruled that the assailants had remained charged only with having caused intermediate bodily harm. The court quashed the Regional Court’s decision and upheld the prosecutor’s order terminating the proceedings.
