Trafficking in human beings is an offence against human dignity and fundamental freedoms and, therefore, a serious violation of human rights. The Group of Experts on Action against Trafficking in Human Beings (GRETA) emphasizes the state’s obligations to respect, fulfil and protect human rights. Such protection includes measures for the proper identification of all victims of trafficking in human beings. It also involves measures to strengthen the rights of trafficked persons, strengthen through appropriate protection, assistance and remedies, including recovery and rehabilitation, which are non-discriminatory regardless of their residence status. By virtue of this fact, in this article we pursue the following objectives: identification of the mechanism for protecting the victims of trafficking in human beings in terms of national and international regulations; knowledge of national and international legal provisions in the field of criminalization of trafficking in human beings; continuous adaptation of investigators to new challenges related to preventing and combating trafficking in human beings; exposing the general and special conditions of hearing the victims of the offences of trafficking in human beings. All these are able to improve the efficiency of the activity of hearing the victims of the offences of trafficking in human beings.
