4.  The applicant was born in 1959 and is currently detained in L'Aquila Prison. 5.  On 16 March 1992 the applicant was arrested and remanded in custody on charges of murder and belonging to a mafia-type organisation. He was also charged with a number of counts of illegally carrying weapons. In particular, he had allegedly aided and abetted the carrying in a public place of a weapon used to commit a number of murders, including that of one M.L. 6.  In a judgment of 16 October 1995, the Palmi Assize Court sentenced the applicant to fifteen years' imprisonment for membership of a mafia-type criminal organisation. He was acquitted of the other charges. 7.  The applicant appealed. 8.  In a judgment of 10 February 1999, the Reggio di Calabria Assize Court of Appeal reduced the applicant's prison sentence to twelve years. 9.  The applicant appealed on points of law. In a judgment of 8 February 2000, the text of which was deposited at the registry on 25 February 2000, the Court of Cassation dismissed the applicant's appeal. 10.  In the meantime, on 19 June 1996, the Reggio di Calabria investigating judge had made a fresh order for the applicant's detention pending trial. On 15 October 1996 he had committed the applicant to stand trial in the Palmi Assize Court. The applicant was charged with several counts of murder and attempted murder, membership of a mafia-type criminal organisation and illegally carrying a weapon. The applicant was accused, in particular, of having given orders to murder M.L. He was also accused of being an accomplice to carrying the weapon used to commit the crime. The applicant had alleged that this weapon had been one of the ones that he had been accused of carrying in the first set of criminal proceedings. 11.  During the proceedings a number of witnesses, including pentiti (former mafiosi who have decided to cooperate with the authorities), were examined. 12.  In a judgment of 22 September 1999, the Palmi Assize Court imposed five life sentences on the applicant and ordered him to serve three years of his sentence in solitary confinement. It imposed an additional sentence of a total of seventy years' imprisonment on him. The decision was based on statements by the pentiti, which were considered to be accurate and credible and were corroborated by other evidence. 13.  The applicant appealed. 14.  From 2000 the applicant was subject to a restricted prison regime, provided for by section 41 bis of Law no. 354 of 26 July 1975 (known as “the Prison Organisation Act”), which, among other things, limited his contact with the outside world. Accordingly, the applicant was no longer brought to the hearing room from prison. He was, however, able to participate in the hearings of 21 February and 15 June 2001 and 5 March 2002 by means of an audiovisual link with the hearing room. 15.  By a judgment of 5 March 2002, the Reggio di Calabria Assize Court of Appeal acquitted the applicant of one of the charges of murder. It found that the offences committed by the applicant were part of a single criminal design (unico disegno criminoso) and reduced his sentence to one life sentence and solitary confinement for two years. 16.  The applicant appealed on points of law. He complained, inter alia, of a failure on the part of the Assize Court of Appeal to give reasons for its finding that, despite a number of gaps in their evidence, the prosecution witnesses were credible. With regard to the murder of M.L., the applicant observed that part of the evidence adduced by the prosecution was that the police had found a P38 Walther pistol inside a car parked near land belonging to him. In the first set of criminal proceedings, however, the applicant had been acquitted of the charge of carrying that pistol. Moreover, that circumstantial evidence did not in any way establish that he had given orders to murder M.L. 17.  The applicant did not allege that there had been a violation of the right to a fair trial on account of the nature of his participation in the appeal hearings. 18.  In a judgment of 26 February 2004, the text of which was deposited at the registry on 3 June 2004, the Court of Cassation dismissed the applicant's appeal. It held that the Assize Court of Appeal had given logical and proper reasons for its decision on all the disputed issues.
