A court expert opinion is a written result of research into questions requiring specialized knowledge. In Russian civil proceedings, the court appoints the examination, and the expert studies the supplied objects and answers the questions set by the court. The opinion is evidence, but it has no predetermined weight and must be assessed with the rest of the case material.
When a court appoints an expert examination
An examination is appropriate where a relevant fact cannot be established through ordinary knowledge and requires expertise in science, technology, art, or a trade. Common examples include:
- construction defects, their causes, and repair costs;
- authenticity of a signature or document;
- market value of property;
- medical causation;
- accounting calculations and transaction flows;
- computer and digital-data analysis.
Legal questions—interpretation of legislation, whether a legal violation occurred, and a party’s liability—are decided by the court. Framing them as expert questions is usually improper.
How the examination is appointed
- A party files an application, or the court raises the need for expertise where procedure permits.
- The participants propose questions, an expert or institution, and information about the objects to be examined.
- The court issues an order containing the final questions, expert, materials, and time frame.
- The expert conducts the research within their professional competence and prepares a written opinion.
- The opinion is examined at the hearing, and the expert may be questioned for clarification or supplementation.
The court must explain why it rejects questions proposed by the parties. Participants may review the appointment order and opinion, propose a particular expert, challenge an expert where grounds exist, and request an additional or repeat examination.
What the opinion should contain
| Section | What to check | Risk if missing |
|---|---|---|
| Expert details | Education, specialty, experience, institution, and warning about legal responsibility | Doubts about competence or procedural form |
| Basis | Court order, questions, dates, and place of research | Work outside the mandate |
| Materials and objects | Complete list and condition of the examined objects | Conclusions based on incomplete or unsuitable data |
| Method and research | Description of operations, calculations, measurements, and methods | The reasoning cannot be tested |
| Conclusions | An answer to every question, clarity, and consistency with the research | Ambiguity, contradiction, or incompleteness |
Court-appointed and private examinations
A study commissioned by a party before the court appoints an examination may help assess the case, formulate questions, and support a position. Its procedural status depends on how it was obtained and the applicable procedural rules, not merely on its title. A court may admit it as documentary evidence or a specialist’s opinion, hear its author, or appoint a judicial examination.
A private report does not automatically replace an examination appointed by court order. At the same time, it should not be rejected solely because one party commissioned it: relevance, admissibility, and reliability must be assessed.
How to review the opinion
- Does the expert’s competence match the subject?
- Were all necessary materials provided?
- Were the objects preserved and lawfully obtained?
- Is the method described and suitable for the question?
- Do the conclusions follow from the research section?
- Are there internal contradictions or answers to legal questions?
- Were alternative explanations and the parties’ source data considered?
A wet-ink stamp or notarized copy does not itself prove scientific validity. Competence, procedure, adequate objects, methodology, and verifiable reasoning are what matter.
Additional and repeat examinations
Additional examination
Used where the opinion is unclear or incomplete, or new questions arise. It may be assigned to the same or another expert.
Repeat examination
Used where the conclusions appear incorrect or insufficiently reasoned, or opinions contradict each other. It is assigned to another expert or commission.
Simple disagreement with the result is insufficient. An application should identify concrete problems: contradictions, incomplete materials, an unsuitable method, work beyond the expert’s competence, or a procedural violation.
Frequently asked questions
Must the court agree with the expert?
No. The court assesses the opinion with other evidence and must explain why it accepts or rejects the conclusions.
Who pays for the examination?
Advance payment is usually made by the party requesting it, or by the parties in proportions set by the court. Final allocation of litigation costs depends on the outcome and procedural rules.
May the expert collect evidence independently?
As a rule, the expert studies supplied materials and requests additional items through the court. The expert should not replace a party in collecting evidence.
Does every expert need a license?
There is no universal license covering every kind of forensic examination. Requirements depend on the field, institution, and special regulation; the relevant qualification and legality of the particular activity must be checked.
