TL;DR
South Korea’s National Court Administration published a survey in which judges reported encountering nonexistent or distorted legal citations in court filings, including cases involving AI-generated material. Judges backed institutional measures, and the administration plans to propose procedural-law changes allowing fines. The survey measures judges’ reported experiences, not the share of filings containing false citations, and it does not establish that AI produced every example.
South Korea’s National Court Administration said on November 2 that judges have encountered nonexistent or distorted legal citations in court filings, including material that may be generated by artificial intelligence, and plans to propose changes to procedural laws that would allow fines. The survey of 360 judges records judges’ reported experiences; it does not measure how many filings contain false citations or establish that AI was responsible in every case.
In the administration’s survey, about 80% of responding judges handling civil, family and administrative cases said they had encountered false or nonexistent precedents. Among judges reporting such experiences, 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 type.
The “about 80%” figure does not apply to all 360 respondents. South Korean daily Kyunghyang Shinmun reported that 243 of the 360 judges (67.5%) had encountered false citations. The court administration’s release does not print that overall figure; it measures judges’ observations rather than the prevalence of false citations in court documents.
Judges also identified who had submitted the material: 164 (69.5%) pointed to litigants representing themselves, and 136 (57.6%) to lawyers acting as representatives or defense counsel. These figures come from a question that allowed multiple responses. The administration said examples included fabricated judgments formatted to resemble Supreme Court decisions, real rulings misrepresented in filings, and text from AI conversations or litigation-strategy notes left in submitted documents.
How False Citations Burden Courts
Fabricated or distorted authorities can force opposing parties and judges to spend time checking whether a cited decision exists and what it actually says. The court administration said this creates an unnecessary verification burden and can hinder the speedy progress of trials. The issue is not limited to the use of AI: the survey describes false citations and gives AI-generated material as one source, while also reporting that both self-represented litigants and lawyers were identified.
The proposed response could affect how lawyers and litigants prepare and verify court submissions. 91.7% of respondents supported an institutional response, according to the source account. The most commonly selected measures included a legal basis for fines, a duty to verify citations and a duty to disclose AI use. The survey records judges’ preferences, not rules already in force or a finding that any named person committed misconduct.

What the Court Survey Measured
The National Court Administration is the administrative arm of South Korea’s Supreme Court. Its Judicial Support Office issued the four-page survey release, titled “Results of the Survey on Citations of AI-Generated False Precedents and Similar Material.” Judges at courts of all levels answered between October 6 and 16, 2026; the administration published the results on November 2.
The release says the survey was prompted by concern that AI hallucinations can produce false or nonexistent precedent citations. It does not state how many judges were invited or reproduce the exact wording of the questions. Those limits matter: the results describe the experiences and views of participating judges, not an audited count of faulty filings across South Korean courts.
The source account says the administration plans to propose amendments to the Civil and Criminal Procedure Acts to permit fines. It also places the proposal against examples of sanctions or referrals involving lawyers in New York and London. Those overseas cases are context, not evidence that South Korea has adopted the same rules.
What the Survey Cannot Establish
The survey does not establish how often false citations appear in filings, because it records judges’ experiences rather than reviewing a defined sample of court documents. The administration also did not disclose how many judges were invited, and the available release does not provide the exact question wording or enough detail to assess how respondents were selected.
Nor does the survey show that AI generated every false citation. The release describes AI hallucinations as a concern and includes AI-related examples, but does not attribute each reported incident to a chatbot or identify the parties involved. It also does not say whether any individual faced a penalty. A translation issue in an English-language report further underlines the need to check the original: the Korean source says 164 judges named the litigants themselves as a source, not that the judges had cited false precedents themselves.
Proposed Rules Face a Next Step
The National Court Administration plans to propose amendments to the Civil and Criminal Procedure Acts that would provide a legal basis for fines, according to the source account. The survey also records support for requiring citation checks and disclosure of AI use, but the available material does not establish that the administration will include every preferred measure in its proposal.
The next developments to watch are the text and timing of any proposed amendments, whether lawmakers take them up, and what standards would apply before a fine could be imposed. Until those details emerge, no new penalty regime is confirmed; the published results are a survey of judicial experience and opinion.
Key Questions
Did the survey find that AI caused all the fake citations?
No. The administration cited AI hallucinations as a concern and described AI-related examples, but the survey does not attribute every reported false citation to AI.
Does “about 80%” mean 80% of all 360 judges?
No. The figure applies to responding judges handling civil, family and administrative cases. Kyunghyang Shinmun reported that 243 of all 360 respondents, or 67.5%, said they had encountered false citations.
Who did judges say submitted false material?
Judges identified both litigants representing themselves and lawyers acting as legal representatives or defense counsel. Respondents could give more than one answer, so the groups are not mutually exclusive.
Are fines already in force for fake citations?
The source account says the National Court Administration plans to propose procedural-law changes that would allow fines. The survey does not report that those amendments have been enacted.
What kinds of false citations did judges report?
Examples included nonexistent judgments presented in a court-like format, real precedents described inaccurately, and AI-chat text or litigation-strategy notes left in filings. The survey does not provide a count of all such filings.
