10.  On 25 October 1991 the Investigating Judge at the Graz Regional Court (Landesgericht) issued a warrant of arrest against the applicant on suspicion of having committed fraud and falsification of documents. The suspicion related to the applicant’s business activities, and in particular two real estate investment projects. The Investigating Judge issued a search warrant ordering a house search at the premises of the SDBV company, a private company (Gesellschaft mit beschränkter Haftung) for which the applicant acted as general manager. The seizure of documents relating to the real estate investment projects was also ordered. That same day the warrant, search and seizure were executed, the latter in the presence of the Investigating Judge. Later in the day the Investigating Judge questioned the applicant and ordered his detention on remand as he found that there existed a danger of the applicant absconding and collusion. As regards the risk of collusion, the Investigating Judge found that there was the danger that the applicant would attempt to influence the employees of the SDBV company and to remove documents which had not been found at the house search. 11.  On 27 October 1991 the applicant requested his release from detention on remand. 12.  On 6 November 1991 the Review Chamber (Ratskammer) of the Graz Regional Court, after an oral hearing in the presence of the applicant, his defence counsel and the Public Prosecutor, dismissed his request. The Review Chamber found that no danger of absconding existed. However, the danger of collusion continued to exist as the applicant might try to influence witnesses not yet heard and to remove any traces of the offence. There was also a danger of his committing further offences. On 20 November 1991 the applicant appealed. At an unspecified date also the Public Prosecutor appealed, arguing that detention on remand should also be based on the risk of the applicant absconding. 13.  Meanwhile, on 11 November 1991, the Investigating Judge ordered that the applicant’s contacts with his defence counsel should take place under the surveillance of the court because of the existence of a danger of collusion. The Investigating Judge found that this measure was necessary because co-suspects were still at large, several witnesses had not yet been heard and there was a risk that the applicant could influence them. The Investigating Judge stated that the validity of this order would expire at the latest when the two-month statutory time-limit for detention on remand based on the risk of collusion would end. The applicant appealed against this decision. He submitted that he did not oppose this measure in principle, however, the measure constituted an unnecessary limitation on his defence rights and the Investigating Judge had failed to order this measure within 14 days as prescribed by law. 14.  On 21 November 1991 the Review Chamber dismissed the applicant’s appeal against the Investigating Judge’s search warrant and the order for surveillance of the applicant’s contacts with his defence counsel. As regards the complaint about the surveillance of the applicant’s contacts with counsel, the Review Chamber found the Investigating Judge’s decision to be correct. This order did not involve any criticism of counsel or any reproach of conduct contrary to law or the disciplinary rules of the members of the bar, but merely had the purpose of preventing any contact whatsoever with third persons in order not to endanger the success of the criminal investigation. The present case concerned the complicated business relations of the SDBV and several other companies managed by the applicant, and the flow of money between them. Further witnesses could only be identified after all the documents seized had been examined and the applicant was to be prevented from influencing them. Furthermore, the decision had been taken within the time limit prescribed by S. 193 § 3 of the Code of Criminal Procedure. The Review Chamber also found the applicant’s complaint that he did not have sufficient access to his case-file unfounded. The Investigating Judge had granted access to the file to the official receiver of the SDBV company and the applicant’s defence counsel, the latter also being given the possibility to make copies of the documents in the file. The applicant’s counsel visited him repeatedly and could have given him copies if he so wished. Moreover, when questioned by the Investigating Judge, the applicant was informed of the contents of the file and about the statements of witnesses already heard. 15.  On 28 November 1991 the Graz Senior Public Prosecutor commented on the applicant’s appeal of 20 November 1991. These comments were not served on the applicant. 16.  On 12 December 1991 the Graz Court of Appeal (Oberlandesgericht) dismissed the appeal lodged by the applicant but granted the Public Prosecutor’s appeal. It found that a serious suspicion existed against the applicant and referred to the details of the criminal investigation. There also existed a danger that the applicant would abscond. 17.  On 15 January 1992 the Review Chamber, after having held an oral hearing, dismissed a further request of the applicant for release. On 13 February 1992 the Court of Appeal dismissed the applicant’s appeal. On 11 March 1992 the Review Chamber dismissed a further request for release by the applicant. 18.  After his conviction on 21 June 1992, the applicant filed further requests for release from detention on remand. Such requests were refused by the Review Chamber on 3 February 1993 and 6 April 1993. Appeals were dismissed by the Court of Appeal on 18 February 1993 and 29 April 1993 respectively. 19.  On 14 February 1992 the Graz Public Prosecutor filed a bill of indictment against the applicant charging him with aggravated fraud. 20.  On 21 April 1992 the trial against the applicant started before the Graz Regional Court. It lasted until 21 June 1992. In the course of the trial the Regional Court heard 52 witnesses, some of them repeatedly on the applicant’s request. Furthermore 5 experts on book-keeping, building and construction matters, real estate assessment, medicine and psychiatry were heard. The applicant frequently requested that the trial be adjourned for lengthy periods and, towards the end of the trial, requested that the trial be repeated or that the case be remitted to the Investigating Judge. On 21 June 1992 the court convicted the applicant of aggravated fraud and sentenced him to four and a half years’ imprisonment. It also acquitted the applicant of an additional charge of fraud raised by the Public Prosecutor at the trial. 21.  On 9 September 1992 the judgment of some 150 pages and the transcript of the trial of some 1400 pages were served on the parties. 22.  On 1 October 1992 the Public Prosecutor filed a plea of nullity and appeal against that part of the sentence concerning the applicant’s acquittal. On 5 October 1992 the applicant filed a plea of nullity and appeal. 23.  On 22 October 1992 the applicant commented on the plea of nullity lodged by the Public Prosecutor. Since he claimed that until the expiration of the time-limit for filing his plea of nullity the defence had had insufficient possibilities to inspect the file, the Supreme Court, on 24 December 1992, decided that the applicant should be granted a new time- limit for filing his plea of nullity and appeal. 24.  On 19 February 1993 the applicant again filed a plea of nullity and an appeal against sentence. The writ repeated in substance the arguments raised earlier. 25.  On 30 March 1993 the Graz Public Prosecutor withdrew the plea of nullity. 26.  On 27 April 1993 the Procurator General (Generalprokurator) submitted the following comments on the applicant’s plea of nullity:
"In the view of the Procurator General the plea of nullity of the accused Bernhard Lanz can be dealt with under Section 285d of the Code of Criminal Procedure. The transmission of a decision is requested. The plea of nullity lodged by the Public Prosecutor’s Office has been withdrawn by the attached declaration of 30 March 1993." 27.  On 9 June 1993 the Supreme Court, sitting in camera, rejected as inadmissible the applicant’s plea of nullity. 28.  On an unspecified date, the Senior Public Prosecutor submitted written comments on the applicant’s appeal. 29.  On 30 August 1993 the Graz Court of Appeal, after an oral hearing in which the applicant and his defence counsel participated, granted the Public Prosecutor’s appeal against the applicant’s sentence and increased it to five and a half years’ imprisonment. In weighing the mitigating and aggravating circumstances, the court found that a higher sentence was called for.
