The MLA request is to be executed in accordance with the relevant provisions of the law of the Slovak Republic; provisions of law of the foreign state may be used only if they are not contrary to the fundamental principles of the Slovak legal order (contrary to the interests of the State protected by the law). A list of questions to be asked must be submitted with the request for a hearing. A witness may be interrogated only to the extent necessary for the criminal proceedings. They may be asked questions to supplement the testimony or to clarify the deficiencies, ambiguities, or discrepancies. Questions must be asked clearly and tactfully. However, the witness may not be asked questions that indicate their response to them or misleading questions, or questions that could contain facts that are to be ascertained only from their testimony. Questions must not unjustifiably interfere with the privacy of the interrogated person with the exception of finding the motives of the accused, particularly if the witness is ill, or a witness damaged by a criminal offence against human dignity. It is possible to request the presence of a police or judicial authority or other persons involved in the criminal proceedings (e. g. a defence lawyer). Their supplementary questions can only be asked via the Slovak authorities.
Hearing victims:
The victim has a right to be accompanied by a confidant. A natural person possessing legal capacity who is chosen by the victim may be a confidant. The confidant shall provide the victim with the required assistance, especially psychological help. The confidant may also be a proxy of the victim. A person who holds the position of a judge, public prosecutor, accused, defence counsel, witness, expert or interpreter in the criminal proceedings cannot be a confidant. The confidant is obliged to maintain the confidentiality of the facts that they learnt during the course of the criminal proceedings.
Hearing children:
If a person under 18 years of age is examined about matters whose recovery from the memory due to his or her age, relationship to the offender or dependence on the offender and the nature and circumstances of the offence could adversely affect his or her mental and moral development or expose him/her to the risk of secondary victimisation, or if it is a criminal offence against human dignity, the examination must be carried out in a particularly respectful and substantive manner. Where the guardian is not present at the interrogation, a psychologist or expert who is to contribute to the proper conduct of the interrogation with regard to the subject matter of the interrogation and the level of intellectual development of the interrogated person shall be invited for the interrogation, as well as a representative of the body of social-legal protection of children and social curatorship. If they can contribute to the correct performance of the interrogation, the legal representative or a pedagogue shall also be invited for the interrogation.
