The employment rate among the inmates in Goldlauter prison is comparatively low. According to the prison governor, this is largely because of the lack of companies in the structurally-weak region. Apart from the out-of-cell and exercise times, unemployed inmates are kept locked in their cells. Furthermore, they do not have the effect offered by work of structuring their days, and hence of helping them to become resocialised. Increasing the number of jobs would be desirable. The prison rules are only available in German. They should be available in the languages most commonly understood by the inmates. The accommodation of persons detained pending removal in prisons is debatable as a matter of principle. The Commission tends to believe that separate deportation facilities should be kept to receive them. As it is the only deportation facility in Thuringia, the situation in Goldlauter prison is made particularly problematic because of the principle of separation, given the small number of persons detained pending removal. It emerges from p. 12 of the reply of the Federal Government to a major interpellation on the situation of German facilities for detention pending removal (Bundestag printed paper 17/10596) that 38 persons detained pending removal were accommodated in Thuringia in all of 2010, whilst there were only 36 in 2009. This frequently entails only small numbers of persons detained pending removal being accommodated in the prison, and increases the danger that unstable inmates, as was described above, have to be singly accommodated and placed under surveillance because it is not possible to place them together with a reliable fellow inmate. In times during which only one single person detained pending removal is accommodated in the prison, the principle of separation of necessity and inadvertently leads to the isolation of the inmate. 5.2 Police units of the Länder The Joint Commission carried out inspection visits in seven police units of the Länder in 2012. By the editorial deadline of this Annual Report, no visit reports had yet been sent on the visits to the Police Stations at Mannheim-Oststadt, Mannheim-Innenstadt, Heidelberg-Mitte, Heidelberg-Süd (2 and 3 November 2012) and the Berlin City police detention unit (14 December 2012). They will therefore not appear until the Annual Report 2013. 63
