34 hierarchical structure, continuously dissatisfied with the working conditions, they may vent it on their subordinates, persons deprived of their liberty or anyone else depending on them. In order to identify or prevent the aforementioned situations, my colleagues check whether the staff members of the place of detention have the qualifications necessary for performing their tasks, and if training and supervision, necessary for quality work, are accessible and efficient enough. In the course of inspecting the facilities, furnishing and equipment of a place of detention, visiting delegations also inspect the premises used by the personnel, in particular the locker rooms, bathrooms, dining and recreational facilities and rest rooms. 7.8. Complaints mechanism In Hungary “everyone shall have the right to submit, either individually or jointly with others, written applications, complaints or proposals to any organ exercising public power”104. With a view to Article 4, Paragraph (2) of the OPCAT, stipulating that deprivation of liberty means any form of detention or imprisonment or the placement of a person in a public or private custodial setting which that person is “not permitted to leave at will by order of any judicial, administrative or other authority”, I consider places of detention as organs exercising public authority. One of the most efficient ways of preventing and eliminating ill-treatment is if the personnel of a place of detention learns as soon as possible about the grievances of the persons deprived of their liberty in connection with their placement and treatment, investigates those grievances within a reasonable period and promptly takes the measures necessary for their redressing. Considering the vulnerability of persons deprived of their liberty and their fear of possible retaliation, I expect the places of detention to ensure the possibility of submitting anonymous complaints. My colleagues examine at each place of detention how persons deprived of their liberty may submit their complaints, how those complaints get registered, investigated and redressed by the staff, and how the complainants are notified thereof. 104 See Article XXV of the Fundamental Law
