TL;DR
South Korea’s National Court Administration published a survey on November 2, 2026, in which judges reported encountering nonexistent or distorted legal citations in court filings. The findings measure judges’ experiences, not the share of filings containing false citations; the administration says it plans to propose procedural-law changes allowing fines.
South Korea’s National Court Administration published a survey on November 2, 2026, reporting that judges have encountered nonexistent or distorted legal citations in court filings, including purported precedents linked to artificial intelligence. The survey covered 360 judges; the administration says it plans to propose changes to procedural laws that would allow fines for false citations.
The survey was conducted from October 6 to 16 among judges at courts of all levels. The administration’s release says about 80% of responding judges handling civil, family and administrative cases had experienced cases involving false or nonexistent precedents. That figure refers to this group, not all 360 respondents: a report by the Korean newspaper Kyunghyang Shinmun put the all-respondent total at 243 judges, or 67.5%.
Among judges who reported encountering false citations, 196 (80.7%) identified precedents that did not exist, while 159 (65.4%) identified real precedents cited with false content. Respondents could select more than one category. The release also lists false or nonexistent statutes and academic materials. These are reports of judges’ experiences; the survey does not establish what proportion of filings contained such material.
Judges identified both litigants and lawyers as sources. In the survey, 164 judges (69.5%) named a party to a case, and 136 (57.6%) named a lawyer acting for a party. The administration described false citations as appearing in documents submitted by both groups. Those figures are responses about who submitted the material, not a count of individuals found responsible.
Judges Seek Rules for False Citations
The findings point to a practical problem for courts: judges and opposing parties may have to spend time checking whether a cited ruling exists and whether it supports the argument made. The administration said false citations can add verification work for the other side and hinder the speedy progress of trials.
91.7% of respondents supported an institutional response, according to the release. Popular proposed measures included a legal basis for fines, a duty to verify citations and a duty to disclose AI use. Those responses show support among surveyed judges, but do not themselves create new legal obligations. Any change would require action through the relevant legislative process.
The issue also reaches beyond the use of AI. The survey records examples of invented cases, inaccurate descriptions of real rulings and other false legal references. A court filing can therefore require scrutiny regardless of whether the error came from an AI tool, a human writer or another source.

What the Survey Measures
The National Court Administration is the administrative arm of South Korea’s Supreme Court. Its four-page Korean-language release said the survey was prompted by concerns that AI-generated errors were producing false or nonexistent precedent citations. The administration’s stated concern was the burden such material places on other parties and the progress of proceedings.
The release describes examples including fabricated judgments formatted to resemble Supreme Court decisions, case numbers attached to reasoning that could not be found in searches, real rulings presented with altered meaning, and text from AI conversations or litigation-strategy notes copied into filings. These examples are described by the administration; the survey does not quantify how often each type occurs.
The denominator matters when interpreting the headline result. The roughly 80% figure applies to responding judges in civil, family and administrative cases. The 67.5% figure reported by Kyunghyang Shinmun is the number of judges said to have encountered false citations among all 360 respondents. The administration’s published release does not itself print that all-respondent percentage.
Survey Limits and Open Questions
The survey measures what judges said they had encountered, not the rate of false citations across court filings. The administration’s release does not state how many judges were invited to participate or provide the wording of the questions, making it difficult to assess response rates and how respondents interpreted each category.
The reported percentages use different denominators. Some describe the subgroup of judges handling civil, family and administrative cases; other figures concern responses to questions about the type or source of false material. Because multiple answers were allowed, category counts should not be treated as mutually exclusive totals.
The release gives examples of material associated with AI but does not establish how many cases involved AI, identify particular litigants or lawyers, or say whether anyone faced a sanction. It also does not set out the proposed legislation’s final text, timing or scope. The survey alone cannot determine whether false citations were deliberate, mistaken or generated by a tool.
Proposed Procedural Law Changes
The National Court Administration says it plans to propose amendments to South Korea’s Civil and Criminal Procedure Acts that would provide a legal basis for fines. The published survey describes judges’ preferred responses, including citation verification and disclosure of AI use, but does not establish that these duties will be included in a bill or adopted.
The next developments to watch are whether the administration publishes draft language, when any proposal is submitted, and how lawmakers and courts define responsibility for inaccurate citations. Until those steps are clear, the survey records judges’ reported experience and preferences rather than a change in current court rules.
Key Questions
What did the South Korean judges’ survey find?
The National Court Administration reported that judges had encountered nonexistent precedents and real rulings cited with false content. About 80% of responding judges handling civil, family and administrative cases said they had experienced such cases.
Does the 80% figure refer to all 360 judges?
No. It applies to respondents handling civil, family and administrative cases. Kyunghyang Shinmun reported that 243 of all 360 respondents, or 67.5%, had encountered false citations.
Did the survey establish that AI caused the false citations?
No. The administration cited concerns about AI-generated errors and described examples of AI-related material, but the survey does not quantify how many false citations were produced by AI or establish the source of each error.
What action is the court administration considering?
It says it plans to propose changes to the Civil and Criminal Procedure Acts to allow fines. The survey also found support for citation-verification and AI-disclosure duties, but the proposed legal text and its prospects are not yet clear.
