If, at a hearing before a trial court, a person heard as a witness or for information contradicts the conclusions of an expert report or provides new information from a technical point of view, the president asks the experts, the public prosecutor, the defence and, if applicable, the civil party, to present their observations. The court, in a reasoned decision, declares either that the proceedings will be dispensed with or that the case will be adjourned to a later date. In the latter case, the court may prescribe any measure it deems useful with regard to the expert opinion.
