8.  On 14 June 1991 the Hamburg Regional Court convicted the applicant, a German national born in 1966, on charges of receiving stolen goods and theft and sentenced him to two years' imprisonment. The execution of the sentence was suspended on probation for a period of four years. 9.  On 18 March 1993 the Ahrensburg District Court convicted the applicant on charges of negligent drunken driving and negligent driving without licence and imposed a fine. Thereupon, the Hamburg Regional Court decided to prolong by two years the applicant's probationary period. 10.  On 15 September 1995 the Hamburg Prosecutor's Office charged the applicant and two co-accused with several counts of fraud, committed between March 1993 and April 1994. 11.  Moreover, on 28 September 1995 the applicant was issued with a penal order (Strafbefehl) by the Hamburg District Court in the framework of a summary procedure. He was sentenced to a fine of 30 German marks (DEM - approximately 15 Euro) per day for thirty days for an offence of fraud, committed in February 1994 to the detriment of Mr H. Upon the applicant's objection, lodged with the assistance of Mr Klingbeil, main proceedings were instituted before the District Court. On 24 November 1995 these proceedings and the proceedings concerning the charges of September 1995, were joined. 12.  In May 2000 the Hamburg District Court convicted the applicant of fraud and sentenced him to ten months' imprisonment. The proceedings concerning the charge of fraud to the detriment of Mr H. were provisionally stayed pursuant to section 154 (2) of the Code of Criminal Procedure as it appeared unnecessary to sanction the offence in question separately, the applicant having been sentenced to ten months' imprisonment in respect of the other fraud offences. 13.  On 21 December 1995 the Kiel District Court issued a penal order against the applicant, convicting him of fraud, committed in August 1994. He was sentenced to a fine of DEM 20 per day for fifty days. 14.  When the postman found nobody at the applicant's home, the order was served in accordance with the relevant legal provisions, by way of a notification in his letter-box on 10 January 1996 to collect the said decision deposited at the local post office in his absence. Since the applicant did not lodge an objection in time, the penal order acquired legal force as the final judgment in the matter on 25 January 1995. On 11 October 1996 the Rendsburg District Court granted the applicant's request for retrial. 15.  On 2 April 1996 the Hamburg Regional Court informed the applicant of its intention to revoke the suspension of his sentence of 1991 and invited him to comment within a period of one week after service of the letter. Due to the applicant's absence from home, the letter was served by way of a notification in his letter-box on 6 April 1996 to collect the said letter at the local post office. 16.  On 18 April 1996 the Hamburg Regional Court revoked the suspension of the applicant's sentence to two years' imprisonment, imposed on 14 June 1991. 17.  In the reasons given for its decision, the Regional Court, referring to section 56f (1)(1) of the Penal Code, found that the applicant had committed criminal offences during the period of probation and had thereby shown that he did not fulfil the expectations upon which the suspension of the sentence was based. 18.  The Regional Court noted that, subsequent to the said suspension, the applicant had been convicted of further criminal offences and that these convictions had become final. Thus he had been convicted of traffic offences by the Ahrensburg District Court on 18 March 1993 and of fraud by the Kiel District Court on 21 December 1995. The court  considered that in particular the applicant's conviction of another offence relating to property had shown that he did not fulfil the expectations upon which the suspension of his sentence was based. Taking into account that the period of suspension had already once been prolonged, other, more lenient measures than revoking the suspension were not possible. 19.  Due to the applicant's absence, the order was also served by way of a notification in his letter-box on 23 April 1996 to collect the decision of 18 April 1996 deposited at the local post. 20.  On 17 May 1996 the applicant, assisted by Mr Klingbeil, submitted an application for the reinstatement of the proceedings against the decision of 18 April 1996 and lodged an appeal against the said decision. 21.  By letter of 15 August 1996 the Hamburg Court of Appeal informed the applicant's counsel that, considering the Public Prosecutor's decision to stay the execution of the sentence (Vollstreckungsaufschub) until 4 August 1996, it would await the outcome of the proceedings before the Kiel District Court regarding his request for reinstatement. 22.  On 22 August 1996 the Court of Appeal decided to grant the applicant's request for reinstatement and adjourned the appeal proceedings to await the final outcome of the Kiel proceedings relating to his request for reinstatement. The Court of Appeal considered that the question whether or not the applicant had committed a further offence of fraud was decisive for its decision on revoking his suspension. It noted that this request had been unsuccessful at first instance, but appeal proceedings were pending. The Court of Appeal dismissed the applicant's request to await the outcome of the proceedings relating to his request for retrial. 23.  On 24 September 1996 the Court of Appeal informed the applicant that, following deliberations, the case remained adjourned to await the outcome of the Kiel proceedings for reinstatement. 24.  On 14 October 1996 a hearing took place before the Court of Appeal, which heard the statements made by Mr H. and the further witness, police officer B., in the presence of the applicant's counsel. The applicant, waiting outside the court building, did not attend the hearing in order not to be seen in case of a confrontation with Mr H., as suggested by his counsel. 25.  Following the hearing, the Court of Appeal dismissed the applicant's appeal against the decision of 21 December 1995 on the ground that the reasons given in that decision were correct in their conclusion. 26.  According to the Court of Appeal, the applicant “had not fulfilled the expectations upon which the suspension of his sentence ... was based, as he committed new offences during the period of suspension” (“hat die Erwartungen, die der ... Strafaussetzung zugrunde lagen, nicht erfüllt, weil er in der Bewährungszeit neue Straftaten begangen hat”). 27.  In its reasoning, the Court of Appeal noted the applicant's final conviction by the Ahrensburg District Court on 18 March 1993. 28.  As regards the penal order issued by the Kiel District Court on 21 December 1995, it considered that the applicant's pending request for retrial might result in the hearing of numerous witnesses. As the prolonged period of suspension had already expired four months ago, the Court of Appeal found that it could not await the outcome of these proceedings. 29.  The Court of Appeal turned next to the proceedings pending before the Hamburg District Court. It noted that, following the applicant's successful appeal against the penal order of 28 September 1995, the District Court had joined these and further criminal proceedings involving the applicant and two other accused and relating to several charges of fraud. In the latter proceedings, trial proceedings had not yet been opened on account of difficult investigations. The Court of Appeal stated that it would not await the outcome of these proceedings either. Rather, it opted for a procedure under section 308 of the Code of Criminal Procedure to examine the question whether or not, in addition to the conviction by the Ahrensburg District Court of 1993, the applicant's criminal offence to the detriment of Mr. H. could constitute a reason for revoking the suspension of his sentence. 30.  The Court of Appeal considered that, having questioned Mr. H. and a further witness, the police officer B., in presence of the applicant's defence counsel, “it had been able to obtain certainty that the applicant was guilty of fraud to the detriment of witness ... [H.] (section 263 of the Penal Code)” (“hat dem Senat ... die Gewissheit verschafft, dass sich der Beschwerdeführer gegenüber dem Zeugen ... [H.] des Betruges schuldig gemacht hat (§ 263 StGB)”). 31.  In this respect, the Court of Appeal took note of both witnesses' indications as to the circumstances of the offence in question as well as to the criminal information laid by the victim H. and the subsequent investigations. Thus, the Court of Appeal found that the applicant had offered H. a mobile phone and a video camera at a low price. When the transaction was to be carried out some time later at a parking place on the motorway, the applicant had taken H.'s money and disappeared without handing over the promised goods. While H. had not identified the applicant on police photographs shown to him at the police department the day after the offence, he did recognise him in a collection of police photographs which had been presented to him by the police officer B. The Court of Appeal considered that both witnesses' statements were true. The court argued that H. had openly talked about his bad conscience regarding the low price of the two objects and he had also admitted that, because he was ashamed, he had not told the truth as to the circumstances of the applicant's disappearance on the occasion of his questioning by the police. Moreover, police officer B. had remembered many details and had also explained an amendment to the minutes of H.'s questioning. 32.  Furthermore, the Court of Appeal indicated that it had inspected the files of the proceedings pending before the Hamburg District Court inasmuch as the collection of police photographs was concerned. The Court of Appeal noted that, when the scene of identifying the applicant had been re-enacted, the witness H., following an initial hesitation as to a photograph showing another person, had clearly recognised the photograph showing the applicant. In these circumstances, the Court of Appeal considered not necessary to re-enact the consultation of police photographs, which had been taken place at the police department one day after the offence. 33.  The Court of Appeal did not take up the suggestion of the applicant's counsel for an open confrontation between the witness H. and several persons, including the applicant. It considered that so much time had elapsed since the offence that the applicant's appearance could have considerably changed. Furthermore, it had not been sure whether the applicant would have participated in such a confrontation. In this situation, it rather relied on the memory of the witness H. 34.  The Court of Appeal concluded that the strict conditions were met for considering an offence, prior to final conviction, as a reason for revoking a suspension. In cases as the present one, awaiting the final conviction would, on account of the considerable possibilities of delay, lead to the unbearable result that criminal offenders could commit further offences during the probationary period without any risk of suffering disadvantages. 35.  According to the Court of Appeal, the applicant's conviction by the Ahrensburg District Court and his criminal offence against H. had shown that, contrary to the initial prognosis, the applicant was not able to live a law-abiding life. While the conviction by the Ahrensburg District Court merely disclosed a general lack of reliability and could not, taken alone, justify revoking the suspension, the applicant had proceeded in the case H. in a way similar to that followed for the offence underlying his 1991 conviction. Accordingly, the suspended prison sentences had had no impact on the applicant. More lenient measures could not therefore be envisaged. 37.  On 22 January 1997 the Federal Constitutional Court refused to admit the applicant's constitutional complaint. 38.  Subsequently, the Pardon Division at the Hamburg Court of Appeal suspended the execution of the sentence pending the proceedings before the Court.
