PREAMBLE

Conscious of the inevitability of the further joint development of justice and technology, believing that technological innovation should join in protecting the authority of justice, and seeking to make judicial procedures more human-centred, the High Council of Justice approves these Principles of the Harmonised Use of Artificial Intelligence Technology in the Judicial System (the “Principles”).

The use of artificial intelligence technologies must be compatible with the right to a fair trial, judicial independence, the equality of participants in proceedings and other fundamental rights and guarantees. Artificial intelligence is a tool in the service of justice, not a subject of it.

The introduction of artificial intelligence must not undermine public trust in the courts through opacity, algorithmic bias or technical error. Artificial intelligence technologies are to serve the efficiency and quality of justice without damaging its authority.

These Principles are intended to bridge the stability of legal procedures in the judicial system and the dynamism of modern technology. The Principles do not establish separate prohibitions; they set out the direction in which the use of artificial intelligence technologies should develop. The Principles do not replace the rules on managing security risks in the use of specific software products, or the guidance of manufacturers and individual institutions on their use.

NECESSITY

Preliminary assessment of whether to use the technology. Before performing a task, it is worth assessing whether artificial intelligence technology can be used to replace, wholly or in part, one’s own intellectual (mental) work or to perform purely technical tasks.

The final decision on using artificial intelligence technology when performing tasks is for each person to make independently, unless such use has been made mandatory by a superior, is dictated by the business process, or is carried out automatically by the automated information systems that support the work.

Proportionality. The scale and depth of the use of artificial intelligence must correspond to the nature of the task and the risks associated with it. The greater the potential impact of the result on individual rights and obligations, the higher the level of human control, verification and reasoning must be.

Explanation. Technical and supporting tasks (search, systematisation, translation, formatting) allow the technology broader autonomy. Tasks that directly form the basis for taking decisions require enhanced human verification.

COMPETENCE

Digital literacy. Those who use artificial intelligence technologies must understand the basic principles of how they work, their capabilities and their limitations. The bodies and institutions of the judicial system are to promote the development of the relevant knowledge and skills, in particular through training, exchange of experience and the formulation of recommended methodologies.

Explanation. The effectiveness and safety of using the technology is determined above all by the competence of the user. Understanding the nature of the models (the probabilistic character of answers, dependence on the quality of the prompt, the possibility of hallucinations) is a precondition for applying all the other principles.

AWARENESS

Artificial intelligence must be used with the awareness that the answers used become the results of one’s own work.

Explanation. Artificial intelligence is merely an interface operating on a prompt-and-answer basis. The operator sets the direction of the answer in the prompt and can thereby influence the result obtained. The quality of the answer depends on the quality of the prompt, its nature, form and other factors that depend directly on the person asking. In essence this is a form of programming, in which the judge (or other court official) is the programmer setting the commands.

In the doctrine of intellectual property law, the results of such computer programming are protected by a right of a special kind (sui generis).

The use of artificial intelligence neither reduces nor redistributes a person’s responsibility for the final result of their work. Reference to the use of the technology cannot serve as an excuse for an error or for improper performance of duties.

Explanation. Responsibility follows authority: whoever is empowered to produce the result answers for it, whatever tools were used to achieve it.

Artificial intelligence technologies may be used to identify, process and interpret data that are to become the basis for a future decision; however, the taking of final decisions must remain the prerogative of the human being for as long as artificial intelligence technologies have not reached a level sufficient for such decisions.

Explanation. This rule is needed as a counterweight to, and elaboration of, the mistaken approach embedded in Article 16 of the Code of Judicial Ethics, which provides that artificial intelligence cannot replace human assessment of evidence. Artificial intelligence allows algorithms to compare images quickly, extract relevant information and group data, giving the judge a convenient basis for taking a decision without infringing their monopoly on the administration of justice.

At the same time, the process of identifying data and presenting them to the judge implies that those data undergo some processing (alteration). In any event, the judge’s decision will depend on whether (1) the full volume of information is obtained and (2) that information has been altered.

The model in which the judge examines the evidence personally works in exactly the same way. There, the decision depends on whether (1) the judge examines all the evidence and (2) does so with due care.

Thus only one question remains open for debate: “Who is liable to make more mistakes when analysing a large volume of information: AI or a judge?”.

IMPARTIALITY

Delegation of morality. The use of artificial intelligence must not be accompanied by instructions to form a biased attitude towards particular persons or circumstances, or to display empathy towards them, save where this is required for research purposes or dictated by the purpose of the process itself.

Explanation. The first law of robotics, formulated by the science-fiction writer Isaac Asimov, states: “A robot may not injure a human being or, through inaction, allow a human being to come to harm.”

Artificial intelligence is not a classic robot, since its assistive nature lies in carrying out the instructions of a human being — a human being with their good and, possibly, bad intentions. The foundation and at the same time the essence of justice is impartiality. That is precisely why, from the very outset of interaction with artificial intelligence, it must not be given any ethical instructions as to who acted well and who acted badly in the situation under examination, or which circumstances are negative and which positive.

Accounting for algorithmic bias. The results produced by artificial intelligence must be received with an understanding that models can reproduce the biases present in the data on which they were trained. Particular care is required with results concerning characteristics of a person on which discrimination is prohibited.

Explanation. A model’s bias is not always obvious and may manifest itself in the selection of arguments, in emphasis or in the tone of the answer. Critical human appraisal of such results is the principal safeguard against transferring algorithmic bias into the application of the law.

Prohibition on circumventing restrictions. A model’s refusal to perform a task once the real purpose of the research has been disclosed must be treated as an expression of the restrictions established for it, which are to be respected and taken into account in further work. Such restrictions must not be circumvented by concealing the true purpose of the research.

Turning to another model in analogous circumstances may be done only in order to test its independent reaction to the same prompt, and must not aim at overcoming the restrictions revealed by the previous model.

Explanation. In individual cases a model may refuse to give an answer, invoking its own rules. Those rules may be relevant restrictions established by legislation, or they may be shaped solely by the developer company’s policies. Further attempts to obtain an answer from the model may produce an irrelevant result if the operator seeks to distort the input data or conceal the real purpose of the research.

RELIABILITY

Applying a two-stage approach. Initial analysis with artificial intelligence technologies must be carried out on materials free from the influence of earlier legal conclusions, decisions or assessments. Such conclusions, decisions or assessments may be supplied to the artificial intelligence only after the initial result has been produced — for verification, comparison and detection of possible errors.

Explanation. Where the materials to be examined for the purpose of taking a decision already contain legal conclusions of the same or another law-applying authority, drawn on the basis of those same materials, the earlier conclusions must be separated from the premises.

The basis on which artificial intelligence forms its results must be clean source data, without documents containing an assessment of the circumstances made by another authority. When using artificial intelligence, a two-stage analysis must be observed:

Stage 1

Materials must be supplied that do not contain decisions of a law-applying authority, unless those decisions are the subject of an independent challenge irrespective of such materials. For example, the artificial intelligence must draw its own conclusions on the basis of:

  • the parties’ submissions (claim, response, objections and so on) without court decisions;
  • the disciplinary complaint without the disciplinary inspector’s conclusion;
  • the materials concerning the candidate without the rapporteur’s conclusion.

Stage 2

All materials must be supplied, including the conclusions of a law-applying authority of the same institutional affiliation.

Examples:

Tax disputes. At stage 1 the taxpayer’s materials that were the subject of examination are supplied, together with the statement of claim, the audit report and the tax assessment notice. At this stage the decisions of the tax authorities in the administrative appeal procedure are NOT supplied, nor are the decisions of lower-instance courts or those made in earlier examinations of the case (if any, or if the case was remitted for fresh consideration).

Once the results of that analysis are obtained, they are passed on together with all the materials for a second assessment, with the task of identifying errors in the earlier conclusions.

Appeal and cassation review, fresh consideration. At stage 1 only the case materials are supplied, without the decisions of the first-instance and appellate courts (if any) or of courts that have already examined the case. At stage 2 all materials and decisions are supplied.

Disciplinary proceedings against a judge or prosecutor. At stage 1 the materials of the disciplinary proceedings are supplied without the conclusion of the disciplinary inspector or of the Qualification and Disciplinary Commission of Prosecutors. At stage 2 the materials are supplied with all conclusions and decisions.

Building the judiciary. At stage 1 all the materials obtained concerning the candidate are supplied. Where the procedure is conducted by the High Council of Justice, at stage 1 the decisions of the High Qualification Commission of Judges of Ukraine containing its own conclusions on the candidate’s integrity are not supplied. At stage 2 all materials are submitted.

This approach will yield clean baseline research results unencumbered by the conclusions of other law-applying authorities. At the second stage it will be possible to test the fallibility of the clean conclusions against the qualified opinion of an authority that is making, or has made, the same analysis.

Verification of sources. References to legal acts, court decisions, academic or other sources generated or cited by artificial intelligence are subject to verification against primary (official) sources before being used.

Explanation. Models are capable of generating plausible but inaccurate or non-existent information (so-called hallucinations), in particular invented citations of court decisions or non-existent versions of legal provisions. Verification against the primary source is the minimum reliability standard for any legally significant result.

Consistency of results . For complex, voluminous or computational tasks, the results produced by artificial intelligence must be verified by re-analysing the same information with another model or by another means. Where the results of different models differ substantially, they may not be used without additional human verification or repeated analysis.

Explanation

In certain categories of complex dispute, or in tasks requiring the preparation of reports, it is worth ensuring a mechanism for cross-checking results with different models. For example, if it is necessary to analyse case materials on the calculation of servicemen’s monetary allowances for different periods, identical tasks are sent for analysis to different models. Ideally a quorum of 3 models (ChatGPT, Claude, Gemini) should be secured. Once identical results are obtained, they are taken into use. If there are discrepancies, all three results are passed to one of the models for verification. If two results were similar and one differed, the matter is passed to the model whose result coincides with that of another.

Despite the higher cost, this technique will substantially reduce risk and may prove cheaper and faster than involving a person.

Uniformity of methodology. When using artificial intelligence technologies, the recommended prompts, instructions, templates and settings must be applied where these have been approved for the relevant body, institution, sector or type of task. Departure from the recommended methodology is permitted only where dictated by the specific features of the particular task.

Explanation

When using artificial intelligence, the recommended prompts and SKILLs should be used where such prompts and SKILLs have been created in advance and recommended for use within the body or sector. Uniformity of methodology ensures that results are comparable and predictable across homogeneous tasks.

Countering procedural manipulation . In applying legal procedures, the user must take appropriate steps to ascertain whether the documents used for examination were created or altered using artificial intelligence.

To that end, it must be possible to obtain from the person who created or supplied such documents a confirmation as to whether or not artificial intelligence was used in creating or altering them.

Where documents were created or altered using artificial intelligence, this should be communicated to the model used for their further examination.

TRANSPARENCY

Readiness to explain. Artificial intelligence must be used in a manner that makes it possible, where required, to explain at which stages of the work, for which tasks and for what purpose the technology was applied. Where the result produced by artificial intelligence substantially affected the content of the document prepared, it is advisable to record the fact of such use.

Explanation. Transparency does not mean that every instance of use must be labelled, but it does presuppose the ability to reconstruct the logic of the work at any moment. It is precisely that ability which is the condition for preserving public trust should doubts arise as to the quality of the result.

CONTROLLABILITY

Artificial intelligence may be used only in those procedures in which human intervention and human verification of the results of its use are ensured.

Where artificial intelligence technology is used in procedures, the results of those procedures must allow for the correction of errors, reversion to a previous state or an appeal.

Explanation . Artificial intelligence cannot be entrusted with taking decisions in any procedure where such a decision is final and will affect rights and obligations with no possibility of correction or appeal. This concerns not instances of analysis, but instances where decisions are prepared without detailed human analysis.

CONFIDENTIALITY

Assessment of the processing environment. When transferring information for processing by artificial intelligence, account should be taken of the data-processing rules of such technologies, the openness (public nature) of the artificial intelligence system, the availability of data protection mechanisms, and the possibility of the service provider making further use of the transferred data to train artificial intelligence models.

For work with case materials or other sensitive information, only local or specially licensed solutions may be used, whose providers have disclosed the terms of data protection and model training.

ADAPTABILITY

Technological neutrality and periodic review. The Principles are not tied to specific software products, models or providers and apply to any artificial intelligence technologies whatever their form. The Principles are subject to periodic review in the light of technological development, the experience accumulated in their use in the judicial system, and changes in legislation.

Explanation. The dynamism of technology declared in the preamble requires that the guidelines themselves remain a living document. Review of the Principles must be based on analysis of the practice of their application, in particular the risks and achievements identified.
