4.  The applicant was born in 1955 and lives in Obninsk in the Kaluga Region. 5.  In 1987 the applicant took part in emergency operations at the site of the Chernobyl nuclear plant disaster. Since 1994, when the link was established between his disability and his involvement in the Chernobyl events, the applicant has been in receipt of monthly health damage compensation. He brought proceedings against the Obninsk town pension authority to challenge the amount of the compensation. 6.  On 20 January 2000 the Obninsk Town Court of the Kaluga Region (“the Town Court”) granted the applicant’s claim and ordered the pension authority to make monthly compensation payments of 3,161.19 Russian roubles (RUR) and pay him the outstanding compensation in the amount of RUR 20,082.86. 7.  The judgment was upheld by the Kaluga Regional Court (“the Regional Court”) and came into force on 6 April 2000. 8.  On 7 June 2000 the Town Court issued two writs of execution, for the monthly compensation and the arrears. On 8 June 2000 the bailiffs brought enforcement proceedings against the pension authority in this respect. By decisions of 25 July and 25 November 2000 the bailiffs forwarded the execution writs to the Obninsk Town Department of the Federal Treasury as an authority responsible for the enforcement and discontinued the enforcement proceedings. 9.  Following the applicant’s request, on 2 October 2000 the Town Court clarified that the enforcement of the judgment should be made at the expense of the federal budget. 10.  On 4 April 2001 the Town Department of the Federal Treasury returned both writs to the applicant without enforcement. They stated, in particular, that under the legislation in force execution writs issued against the Federal Treasury should be submitted directly to the Ministry of Finance. 11.  Following the applicant’s request, on 1 June 2001 the Town Court clarified that the monthly compensation payments awarded by the judgment of 20 January 2000 should be paid with subsequent indexation based on the statutory minimum wage. 12.  On 24 July 2001 the applicant applied to the Ministry of Finance for the enforcement of the judgment. 13.  The outstanding compensation of RUR 20,082.86 was paid to the applicant on 22 April 2002, two years and sixteen days after the entry into force of the judgment. As regards the monthly compensation, in 2000 it was paid monthly in the amount of RUR 292.22; the arrears of RUR 31558.67 were paid by a single instalment on 30 October 2002. In 2001, 2002 and the first half of 2003 the amount of the monthly payments was RUR 350. The amount of RUR 33734.28 was transferred to the applicant’s bank account on 16 December 2002 to pay off the arrears for 2001. The arrears for 2002 in the same amount were paid on 9 April 2003. 14.  According to the Government’s information, on 19 February 2003, following the prosecutor’s application, the Presidium of the Kaluga Regional Court quashed the ruling of the Town Court of 1 June 2001 in which the latter clarified the judgment of 20 January 2000. Following a fresh action brought by the applicant, on 17 April 2003 the Town Court found that the amount of the compensation established in its judgment of 20 January 2001 should have been increased as the relevant legislation required that it was subject to indexation based on the statutory minimum wage in 2001 and on the statutory living wage in 2002. It ordered the Obninsk Social Security Service to pay the applicant the health damage compensation monthly in the amount of RUR 6,574.41 with subsequent indexation in accordance with law. It also ordered the payment of arrears for 2001‑2002 totalling RUR 48,466.63. The judgment was upheld by the Kaluga Regional Court and came into force on 29 May 2003.
