CAT/C/LIE/CO/3 employed at Vaduz National Prison were not used in actual fact in 2009. The Committee also notes with appreciation that programmes of supervision, as recommended by the Corrections Commission, and the possibility of making them mandatory, are currently under discussion (art. 10). The State party should ensure that the mandatory initial and continuous training programmes, as well as programmes of supervision, for prison officers are effectively implemented and attended so that they are fully aware of the rights of persons deprived of their liberty. 21. The Committee is concerned that no special training programme on the prohibition of torture and other forms of ill-treatment exists for medical personnel who receive their training abroad, whereby a “certain dependency therefore exists on the manner in which content of medical training is defined abroad”. The Committee furthermore notes that it has no information with respect to training of members of the judiciary and prosecutors in the State party on the Convention and the Manual on Effective Investigation and Documentation of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (the Istanbul Protocol) (art. 10). The State party should take measures to ensure that all medical personnel dealing with persons deprived of their liberty receive complementary training, in addition to education received abroad, on the prohibition and prevention of torture. The Committee recommends that the Manual on the Effective Investigation and Documentation of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (“Istanbul Protocol”) is integrated into such training programmes and into the training of those involved in the investigation of torture, such as judges and prosecutors, in addition to their training on the Convention against Torture. These programmes should be subject to regular assessment and evaluation. Detention conditions 22. The Committee notes the limited holding capacity and the shortage of space and personnel resources of Vaduz National Prison. In particular, the Committee is concerned that the space restrictions and personnel limitations, has resulted, on occasions, in the removal of prisoners from the prison by police for interrogation without the presence of a corrections officer, contrary to applicable domestic law (art. 89of the Execution of Sentences Act). The Committee is furthermore concerned at the fact that the national prison holds different categories of detainees, including convicted prisoners, prisoners on remand, detainees awaiting deportation and juveniles. While appreciating information on arrangements for separation between men and women and juveniles and adults, the Committee is concerned that separation between pretrial prisoners, persons detained for expulsion and convicted prisoners is not always possible. In this regard, the Committee notes with regret the discontinuation of a project initiated in 2002 aimed at better ensuring separation and infrastructure of the Vaduz National Prison subsequent to the result of a referendum (arts. 11 and 16). The State party should undertake an assessment of the detention facilities in Vaduz National Prison with a view to ensuring adequate personnel and space so as to conform to relevant international human rights standards. Immediate measures should also be taken to ensure that interrogations of prisoners by police always take place in the presence of a corrections officer. The Committee strongly recommends that the project initiated in 2002 to improve infrastructure and ensure better separation of detainees in Vaduz National Prison be reintroduced and completed. 7
