4.  The applicant was born in 1965 and is serving his prison sentence in the Ankara Sincan F-type prison. 5.  In March 2000, the applicant, who was accused of murder, armed robbery and membership of an illegal organisation, namely the TKP-ML (Türkiye Komünist Partisi / Marksist Leninist, Turkish Communist Party / Marxist Leninist), was placed in detention on remand in the Nevşehir prison. 6.  On 19 December 2000 the applicant was transferred to the Ankara Sincan F-type prison. 7.  On 2 January 2001 the Disciplinary Board of the F-type prison (“the Board”) found the applicant guilty of having damaged prison property and, pursuant to Article 157 of the Regulations on the administration of penitentiary institutions and the execution of sentences (“the Regulations”), prohibited him from receiving visitors for a period of three months. According to the Board’s decision, on 24 December 2000 the applicant had broken the ventilation in his ward and written the name of an illegal organisation on his wall. The decision of the Board was reviewed and upheld by the Ankara State Security Court, in accordance with Article 116/5 of the Code of Criminal Procedure. The court delivered its decision on the basis of the case file. It also referred to the applicant’s statement in which he had admitted committing these acts in protest against the general situation in F‑type prisons. The penalty was enforced between 25 January 2001 and 25 April 2001. 8.  On 13 March 2001 the Board once again imposed a disciplinary sanction on the applicant and prohibited him from receiving visits for two months. According to the Board’s decision, on 15 February 2001, following a meeting with his lawyer, the applicant had refused to be searched by prison officers and had shouted slogans. In his defence submissions, the applicant admitted that he had resisted the prison officers when he was ordered to take off his shoes. On 28 March 2001 the Board’s decision was reviewed and upheld by the Ankara State Security Court. The applicant filed an objection with the public prosecutor against this decision under Article 162 of the Regulations. On 2 May 2001 the public prosecutor rejected the applicant’s request. The penalty was enforced between 27 April and 27 June 2001. 9.  On 17 May 2001 the Board found the applicant guilty of having damaged prison property, possessing a sharp cutting instrument made from a prison bed, and having an excessive amount of money in his possession. It accordingly prohibited him from receiving visitors for a period of three months. In the meantime, Law no. 4675 entered into force, which stipulated that decisions delivered by Disciplinary Boards were to be reviewed by the Enforcement Judge. Accordingly, on 21 June 2001, the decision of 17 May 2001 was reviewed. The judge upheld the Board’s decision, on the basis of the case file and taking into account the applicant’s statement. This decision was served on the applicant on 3 July 2001 and the penalty was enforced between 31 July and 30 October 2001. 10.  On 21 May 2001 the applicant received a reprimand for having chanted slogans in the prison. The Board held that the applicant should be warned that he would receive heavier penalties if he continued committing similar offences. 11.  On 18 and 22 May 2001 respectively, the prison guards prepared two incident reports according to which the applicant had damaged public property by breaking the loudspeaker in his cell and had incited other inmates to disturb order by chanting slogans. In his statement dated 25 May 2001, the applicant admitted that he had chanted slogans but denied that he had damaged the loudspeaker in his cell. On 29 May 2001 the Board found the applicant guilty and prohibited him from receiving visitors and from sending and receiving letters for a period of a month. On 21 June 2001 the decision was reviewed and upheld by the Enforcement Judge. That decision was served on the applicant on 29 June 2001 and he filed an objection against it. On 4 July 2001 the Enforcement Court dismissed the applicant’s objection and the penalty was enforced between 29 June and 29 July 2001. 12.  On 6 June 2001 the applicant was caught by prison guards as he was climbing onto the window bars of his cell. In his statement dated 14 June 2001, the applicant maintained that he had climbed up to reach a newspaper which was allegedly on the roof. On 18 June 2001 the applicant was once again prohibited from receiving visitors for three months by the Board for having climbed onto the window bars. On 2 July 2001 the penalty was reviewed and upheld by the Enforcement Judge. That decision was served on the applicant on 1 November 2001.
