4.  The applicant was born in 1976 and lives in Bielsk Podlaski. 5.  The facts of the case were not in dispute and may be summarised as follows. 6.  The applicant was detained in Siedlce Prison from 26 January to 19 April 2007 and from 15 July to 15 October 2009. 7.  The applicant submitted that, during his detention in Siedlce Prison, he had been held in cells where the amount of space per person had been below the Polish statutory minimum standard of 3 m². He also submitted that he had been held in cells with smokers. Moreover, he raised the problems of humidity, lack of hygiene and warm water and limited access to make telephone calls. 8.  The domestic courts found that the applicant had been detained in an overcrowded cell during his detention in Siedlce Prison from 15 July to 15 October 2009 (91 days), when he had been assigned to cell no. 616 (15.94 m²) with 5 other prisoners (2.65 m² per person). 9.  The courts further found that the toilet areas had been separated from the rest of the living space in the cells in compliance with the relevant law. The toilet annex had only cold running water. It was further noted that the cells were adequately equipped. The applicant was held in cells in accordance with his declaration about his tobacco habits. 10.  On 13 July 2013 the applicant brought a civil action against the State Treasury for infringement of his personal rights and for compensation on account of his detention in an overcrowded cell in Siedlce Prison.

It confirmed, however, that the applicant had been detained temporarily in an overcrowded cell, from 15 July to 15 October 2009. 12.  On 17 February 2015 the Siedlce Regional Court (Sąd Okręgowy) dismissed the applicant’s appeal.
