Yes, it is possible. In criminal proceedings experts are invited to elaborate expert opinions in case special knowledge is required to establish the circumstances important for the case, which exceeds the level of general knowledge available to authorities involved in criminal proceedings. Experts may be invited to present their opinions either in pre-trial proceedings (to provide expert evaluations), where they are invited either by the Police or the public prosecutor, in trial proceedings (to provide expert evidence), where they are invited by the presiding judge. The experts are selected from a list of accredited experts maintained by the Ministry of Justice or by Regional court, or it can be another person or legal entity that has the required professional knowledge. Expert opinions may also be submitted as evidence by other parties to the proceedings, typically the accused person.
