18 The public officials working at the Department are all experts with an outstanding theoretical knowledge in the field of the treatment of persons deprived of their liberty, many of them publish regularly, teach at universities and speak as guest speakers at numerous professional and promotional events. The professional activities of my colleagues contribute to the prevention of ill-treatment and to the dissemination of preventive approach among less-affected members of society. 3.2. External experts In addition to the public servant staff members of my Office, I may also authorize, either permanently or on an ad hoc basis, other experts to contribute to performing the tasks of the NPM.56 The Ombudsman Act does not specify what types of experts I should involve, in addition to physicians, psychologists and lawyers, in performing the tasks of the NPM. In the absence of a legal provision, I relied on the report published on the SPT’s visit to Sweden between March 10 and 14, 2008, pointing out that prevention as stipulated by the OPCAT necessitates the examination of rights and conditions from the very outset of deprivation of liberty until the moment of release. Such examination should take a multi-disciplinary approach and involve, for example, the medical profession, children and gender specialists and psychologists in addition to a strict legal focus.”57 Selection of the experts participating in the performance of the NPM’s tasks was carried out on the basis of the roster of experts recommended partly by the CCB, partly by ELTE University under an agreement signed with the President of the University. When selecting translators participating in interviewing foreigners who do not speak languages spoken by my colleagues, I relied on the recommendations of the UNHCR Regional Representation for Central Europe. Since we could not fill the physician positions in the Department, the physicians–a psychiatrist, a child psychiatrists and a pediatric cardiologist–participating in the NPM’s visits in 2015 were all external experts with ad hoc authorization. In certain cases I also involved experts by experience, i.e., persons with practical knowledge of the operation of the selected place of detention, in the preparations of the visits. The work and remuneration of external experts participating in performing the NPM’s tasks is determined on the basis of civil contracts. External experts have to make a written statement on the confidential treatment of the data and information they may learn in connection with performing their task. They may not reveal those data and information, without my written consent, to any third person, and they may not make any statement to any third person and/or the media.
