The assistance of expert witnesses shall be requested by the judge or the prosecution, either on their own initiative or at the request of one of the parties to the proceedings, and they shall be remunerated. In these cases, the doctor, psychologist, or computer engineer uses their technical and scientific knowledge to better understand what happened.
