declared unconstitutional by the Polish Constitutional Court in February 2014, and that the legislation would subsequently be amended. 80. The CPT also visited the Warsaw sobering-up centre, which made a positive impression on the delegation. Report and response published in June 2014, CPT/Inf (2014) 21 and CPT/Inf (2013) 22 Report on the ad hoc visit to Portugal in May 2013 and response of the Portuguese authorities (situation at Lisbon Central Prison, investigations into alleged ill-treatment) 81. The CPT’s delegation found that the situation at Lisbon Central Prison, in terms of both material conditions and the treatment of inmates by prison staf, had not improved in the 15 months since the February 2012 periodic visit to Portugal. Lisbon Central Prison continued to be afected by chronic overcrowding of almost 150% and very poor material conditions; damp cells, crumbling plaster, broken windows, a lack of artifcial lighting and dilapidated mattresses were evident in most of the basement areas of the prison. The CPT comments that such conditions could be considered as amounting to inhuman and degrading treatment. The report recommends that strong action be taken to renovate the diferent wings, starting with the basement units. The Committee also recommends that the Portuguese authorities vigorously pursue their eforts to combat prison overcrowding, by placing further emphasis on non-custodial measures in the period before the imposition of a sentence, increasing the use of alternatives to imprisonment and adopting measures facilitating the reintegration into society of persons deprived of their liberty. General Report of the CPT, 2013-2014 ► Page 40 The report also refers to a number of credible allegations of ill-treatment of inmates by prison ofcers at Lisbon Central Prison and the CPT reiterates the importance of undertaking efective investigations into such allegations. Moreover, inter-prisoner violence was a serious issue on certain wings of the prison. Recommendations are made to improve the recording of physical injuries observed upon admission to the establishment or following a violent incident inside the prison and also to increase stafng levels. Further, as regards the small numbers of juveniles held at Lisbon Central Prison, the CPT found that their safety was at risk in view of the level of violence in the prison and that they were not provided with purposeful activities or appropriate support. The report recommends that the juveniles be transferred to another establishment ofering both an appropriate environment and a tailor-made regime. In their response, the Portuguese authorities concur with the CPT’s concerns and afrm their policy to keep juveniles separate from adult ofenders and in institutions close to their social and cultural background. Reference is made to a pilot project in three prisons. As regards activities for prisoners at Lisbon Central Prison, almost 900 out of 1310 prisoners were not involved in any work or educational activities at the time of the visit. Moreover, educational activities were reserved for sentenced prisoners and registration for the different courses was only possible at the beginning of the academic year (i.e. September). In their response, the Portuguese authorities refer to the steps being taken to expand the application of alternative measures to imprisonment and to the ongoing investment to improve prison conditions at Lisbon Central Prison.
