5.  The applicant was born in 1933. He was detained in Aachen Prison until his release on 1 March 2008. 6.  The applicant has been convicted twenty-two times since 1949, initially notably for smuggling and thefts. Since 1955 he has spent most of his life in prison. 7.  On 23 April 1968 the Cologne Regional Court convicted the applicant on two charges of joint aggravated (armed) robbery of a bank, sentenced him to twelve years’ imprisonment and ordered his preventive detention. 8.  On 20 January 1970 the Cologne Regional Court convicted the applicant of aggravated robbery-style theft committed against a money courier. Taking into account the term of imprisonment from the judgment of 23 April 1968, it imposed on the applicant a cumulative sentence of thirteen years’ imprisonment, but quashed the order for preventive detention. The remainder of his prison sentence was suspended on 31 March 1977 and the applicant was released and placed on probation; this suspension was subsequently revoked. 9.  On 7 December 1978 the Cologne Regional Court convicted the applicant, in particular, of two counts of joint aggravated (armed) robbery, of aiding and abetting another joint aggravated robbery, of three counts of aggravated theft and one count of attempted aggravated theft. It sentenced him to thirteen years’ imprisonment and ordered his preventive detention under Article 66 § 1 of the Criminal Code (see paragraphs 45-46 below). 10.  The Cologne Regional Court found that the applicant, who had been released from prison on 31 March 1977 and had a job, had committed the said offences between June 1977 and his arrest in November 1977. Together with two accomplices, he had robbed a money courier and a bank, armed. He had further stolen or attempted to steal together with others several cars which had later been used when committing the two robberies and another bank robbery in which the applicant had not otherwise participated. 11.  Having consulted an expert, the Cologne Regional Court found that since his youth the applicant had been strongly inclined to commit offences and to make his living thereby, even though he could have worked. Serving long sentences had not prevented him from reoffending and from committing more and more serious offences at ever shorter intervals. Since there were no indications that the applicant would not reoffend, he was dangerous to the public. 12.  On 11 April 1980 the Federal Court of Justice dismissed the applicant’s appeal on points of law against the judgment of 7 December 1978, which thereby became final. 13.  On 29 April 1983 the Bonn Regional Court reopened the proceedings in respect of one of the applicant’s accomplices, W., who had also been convicted of bank robbery on 7 December 1978, and acquitted him. The third accomplice to the robbery, Schw., had confessed that he had wrongfully incriminated both W. and the applicant in this offence. The applicant’s request for reopening of the proceedings against him was subsequently dismissed. 14.  On 2 February 1993 the Bonn Regional Court suspended the order remanding the applicant in preventive detention from 26 April 1993 (when the applicant would have served his full prison sentence), granted probation and ordered the applicant to be placed under supervision of conduct (Führungsaufsicht) for four years. 15.  The applicant served the sentence imposed by the judgment of 7 December 1978 in full, as well as the remainder of the sentence imposed by the judgment of 20 January 1970, until 26 April 1993. 16.  On 20 May 1996 the Koblenz Regional Court convicted the applicant of aggravated (armed) robbery committed with others, sentenced him to ten years’ imprisonment and ordered his preventive detention. It found that the applicant, armed with a machine gun, had robbed a bank together with an accomplice in June 1995; he had been in custody since then. 17.  On 13 November 1996 the Federal Court of Justice quashed the judgment of 20 May 1996 so far as the applicant’s sentence and his preventive detention were concerned and remitted the case to the Regional Court. 18.  On 18 June 1997 the Koblenz Regional Court again sentenced the applicant to ten years’ imprisonment. It considered the conditions for his preventive detention under Article 66 of the Criminal Code to have been met. However, for reasons of proportionality, the court did not order the applicant’s preventive detention, which would then have been of indefinite duration. It argued that from 8 June 2005 onwards, the applicant would be placed in preventive detention on the basis of the judgment of 7 December 1978, as the provisional suspension of his preventive detention on 2 February 1993 was likely to be revoked, and that he would be of advanced age afterwards. 19.  On 6 July 1998 the Bonn Regional Court, acting as the court dealing with the execution of sentences, revoked the suspension of the applicant’s provisional preventive detention granted on 2 February 1993 pursuant to Article 67g § 1 no. 1 of the Criminal Code (see paragraph 51 below) in view of his renewed conviction for aggravated robbery committed in June 1995. 20.  On 1 September 1998 the Cologne Court of Appeal, disagreeing with the General Public Prosecutor’s view, dismissed the applicant’s appeal against the decision of 6 July 1998. The applicant’s objection was of no avail. 21.  On 25 February 1999 the Federal Constitutional Court declined to consider the applicant’s constitutional complaint (no. 2 BvR 1712/98) against the decision of the Cologne Court of Appeal dated 1 September 1998. It found that the applicant had failed sufficiently to substantiate his complaint, which was therefore inadmissible. It observed, however, that the provisions of the Criminal Code did not permit the revocation of the suspension of the applicant’s provisional preventive detention after the expiry of the four-year period of supervision of his conduct. It was firstly up to the courts dealing with matters relating to the execution of sentences to examine whether the revocation decision could be amended at the applicant’s request or of the court’s own motion. 22.  On 13 April 1999 the Cologne Court of Appeal dismissed the applicant’s request, supported by the Public Prosecutor General, for the decisions of the Bonn Regional Court dated 6 July 1998 and of the Cologne Court of Appeal dated 1 September 1998 to be set aside. It found that under Article 68c § 3, second sentence, of the Criminal Code (see paragraph 52 below), the supervision of the applicant’s conduct for four years ordered in 1993 had not ended until now as the applicant had been detained since June 1995 and the time spent in detention did not count towards the period of the supervision of his conduct. Therefore, the provisional suspension of the preventive detention order against him could still be revoked in 1998. 23.  On 13 September 2004 the Aachen Regional Court started the proceedings for examination of the need for the applicant’s preventive detention after the end of his prison term by requesting the Public Prosecutor’s Office to send the case file and by ordering the Aachen Prison authorities to make a statement. 24.  The director of Aachen Prison thereupon sent a statement dated 30 December 2004, which he supplemented at the court’s request on 25 February 2005. Following two reminders from the Regional Court, the Public Prosecutor’s Office submitted the case file to the court in March 2005. 25.  On 30 March 2005 the Regional Court requested a psychiatric expert to give an opinion on whether the applicant was still so dangerous that his preventive detention was necessary. 26.  The applicant served his prison sentence in full, up to 7 June 2005. From 8 June 2005 the applicant was in preventive detention ordered in the judgment dated 7 December 1978. 27.  Following an inquiry of the Regional Court at the applicant’s request, the latter was examined by the psychiatric expert on 3 August 2005. Following two further requests made by the applicant to make progress in the proceedings, a report drafted by two psychiatric experts was submitted to the court on 16 November 2005. 28.  On 30 March 2006 the Aachen Regional Court, having heard the applicant and his counsel on that day and having consulted the director of Aachen Prison and two experts, ordered the execution of the preventive detention order in respect of the applicant made in the Cologne Regional Court judgment of 7 December 1978. 29.  The Regional Court considered in detail the previous convictions of the applicant, aged 72, notably his convictions for aggravated robbery and robbery-style theft by judgments dated 23 April 1968, 20 January 1970, 7 December 1978 and 18 June 1997. 30.  The Regional Court found that the execution of the preventive detention order against the applicant was still necessary in view of its objective (Article 67c § 1 of the Criminal Code, see paragraph 48 below). In the court’s view, the applicant was likely to commit further serious offences similar to those he had previously committed if released (Article 67d § 2 of the Criminal Code, see paragraph 50 below). 31.  In the Regional Court’s view, the applicant had been a persistent offender since his youth, who had reoffended shortly after being released on probation and after serving long prison sentences. He did not have any family ties outside prison and did not have any precise plans as to what he would be doing when released. He was lively for his age. He suffered from orthopaedic health problems, notably injuries to his left knee and his hip, which, as found by the prison doctor, entailed a considerable but not extreme walking disability. His walking ability could have been considerably improved by an artificial hip, but he refused to have the operation while he was in prison. Having consulted the prison doctor, the court took the view that the applicant’s walking disability could not yet be considered so severe as to render him physically unable to commit an offence, notably as his previous offences had not required significant mobility. 32.  The Regional Court, having regard to the report dated 16 November 2005 by the two psychiatric experts who had examined the applicant, took the view that the applicant’s personal and social situation remained similar to that which had existed when he was released from prison in 1993 at the age of 59. He had not changed his attitude towards offences and therefore remained dangerous. 33.  On 26 June 2006 the Cologne Court of Appeal dismissed the applicant’s appeal against the Aachen Regional Court decision of 30 March 2006. It did not share the view expressed by the Federal Constitutional Court in its decision dated 25 February 1999 that the revocation of the suspension of the applicant’s provisional preventive detention had no longer been possible on 6 July 1998 according to the provisions of the Criminal Code. Pursuant to Article 67g § 5 of the Criminal Code (see paragraph 51 below), preventive detention would cease to apply at the end of the offender’s supervision of conduct if the court had not revoked the suspension of his preventive detention before that date. However, the supervision of the applicant’s conduct for four years ordered in 1993 had not ended, as the applicant had been detained since June 1995 and the time spent in detention did not count towards the duration of the supervision of conduct (Article 68c § 3, second sentence, of the Criminal Code). 34.  Moreover, the Court of Appeal found that, contrary to the applicant’s submissions in his appeal, the fact that the Regional Court had failed to reach a decision on the applicant’s preventive detention before the applicant had served his full prison sentence on 7 June 2005 (Article 67c § 2 of the Criminal Code) did not render its decision unlawful. In any event, the mistake had been remedied ex nunc when the decision was taken. 35.  According to the Court of Appeal, the applicant needed to be kept in preventive detention in order to protect the public from particularly dangerous offenders. The applicant did not truly question or regret his offences. As found by two experts in an additional report, the applicant’s statements concerning his offences were very similar to those he had made before his previous release from prison, following which he had reoffended. The applicant’s age and the health problems accompanying it did not, at least at the time, warrant a different conclusion as to the danger he presented to the public. The applicant had also already reached retirement age when he had committed his last offence. As found by the prison doctor on 25 February 2005, his knee and hip were damaged. The court found that these illnesses caused pain, but did not entail a walking disability. 36.  Remanding the applicant in preventive detention was also not disproportionate, as he was likely to commit serious offences if released. However, in view of his present illnesses and the usual diminution of physical fitness with advancing age the applicant’s preventive detention would probably not last until its termination in 2015, but would be suspended on probation. Therefore, the applicant should be prepared for a life outside prison. 37.  On 14 July 2006 the Cologne Court of Appeal dismissed the applicant’s objection against that decision. 38.  On 3 August 2006 the applicant lodged a complaint with the Federal Constitutional Court against the decisions of the Aachen Regional Court dated 30 March 2006 and of the Cologne Court of Appeal dated 26 June 2006. He claimed that his right to liberty had been violated. He argued that, as had been expressly found in the decision of the Federal Constitutional Court dated 25 February 1999, the revocation of the suspension of his provisional preventive detention had no longer been possible on 6 July 1998. Moreover, he had been remanded in preventive detention since 8 June 2005 without a legal basis, in particular because the courts had failed to reach a decision on the necessity of that remand in custody within a reasonable time, as required by Article 67c § 1 of the Criminal Code as interpreted in the well-established case-law of the courts of appeal and of the Federal Constitutional Court itself (see paragraph 49 below). Due to his age, 73, and his walking disability, which had already made him physically unable to reoffend, his preventive detention was also disproportionate. 39.  On 21 September 2006 the Federal Constitutional Court declined to consider the applicant’s constitutional complaint (file no. 2 BvR 1614/06). It found that the complaint had no prospects of success. 40.  The Federal Constitutional Court considered that, even assuming that the decisions on the necessity to remand the applicant in preventive detention should have been based on paragraph 1 of Article 67c of the Criminal Code, they did not violate the Basic Law. Contrary to the applicant’s view, he had not been detained without legal basis in the period between the end of his prison term and the Regional Court’s decision ordering the execution of the preventive detention order against him. Referring to its decision of 9 March 1976 (file no. 2 BvR 618/75, see paragraph 49 below), it found that the execution of a preventive detention order on the basis of a judgment of the sentencing court ordering it under Article 66 of the Criminal Code was permitted if the Regional Court dealing with the execution of sentences had begun with its examination under Article 67c § 1 of the Criminal Code before the person concerned had fully served his prison sentence, even if it had not yet taken its decision. 41.  The Federal Constitutional Court further took the view that the Regional Court, which had started the proceedings concerning suspension of the applicant’s preventive detention some nine months before the end of the applicant’s prison term, had not delayed the proceedings in a manner which would violate his right to liberty. 42.  Furthermore, the decision of the courts dealing with the execution of sentences not to suspend the preventive detention order against the applicant and grant probation did not appear arbitrary in view of the applicant’s repeated serious offences and there was no violation of the courts’ duty to investigate the matter. 43.  On 20 December 2007 the Aachen Regional Court decided to suspend the preventive detention order made against the applicant in the Cologne Regional Court’s judgment of 7 December 1978 and grant probation as of 1 March 2008; it further ordered supervision of the applicant’s conduct. Having regard to all the circumstances of the case before it, including, in particular, the applicant’s walking disability, the court considered, in accordance with the view taken by the medical expert it had consulted and contrary to the view taken by the director of Aachen Prison and the Cologne Public Prosecutor’s Office, that it was to be expected that the applicant would not commit further serious offences similar to those he had previously been convicted of if released (Article 67d § 2 of the Criminal Code).
