asiantuntijatodistaja

Asiantuntijatodistaja is a person with specialized professional expertise who provides testimony in legal proceedings to clarify issues that require professional knowledge beyond common understanding. The role is used in Finnish judicial practice, and the expert may be appointed by a court or by a party to a case to evaluate facts, examine evidence, and offer a professional opinion on technical questions. The primary written deliverable is an asiantuntijalausunto, an expert opinion, which the judge uses alongside other evidence.

Appointment and scope: The court appoints the expert when the case involves matters requiring specialized analysis, such as medical findings, engineering assessments, or financial analyses. The expert’s mandate specifies the questions to answer and the standards to apply. Before accepting, the expert should disclose any conflicts of interest or prior relationships with the parties.

Duties and process: An asiantuntijatodistaja must perform work independently and impartially, following professional standards. They prepare a written report detailing methods, data, reasoning, and conclusions, and may be summoned to Court to explain and defend the findings under cross-examination. If new facts emerge, they may be asked to provide supplementary opinions.

Qualifications and limits: The expert should hold recognized qualifications in the relevant field and maintain professional integrity. Their task is to illuminate technical aspects and provide evidence-based analysis; they do not decide legal questions. The weight given to their testimony depends on credibility, methodology, and the quality of reasoning.

Context: In Finland, expert testimony is used in civil, criminal, and administrative cases, and the process is governed by applicable laws and statutes. The asiantuntijatodistaja thus serves to clarify complex issues and support judicial decision-making with expert insight.
