South Korea proposes court sanctions for AI-fabricated citations, from cost-shifting to bar referral

After judges caught nonexistent AI-generated precedents in court briefs, South Korea's National Court Administration proposed a framework that shifts litigation costs, refers lawyers for discipline, and records the falsity in the judgment. A separate bill would add fines.

South Korea is assembling a way to punish lawyers and litigants who file court documents citing precedents that do not exist. The trigger was concrete. In April, the Seoul High Court identified several nonexistent precedents in an appeal brief filed in a lease-deposit return dispute, and similar fabrications turned up in both self-represented and lawyer-prepared filings. The common thread was generative AI producing plausible-looking case law that no court ever decided.

In response, the National Court Administration (법원행정처) convened a task force that ran from November 2025 to March 2026. According to Korean legal press, it drew ten members, eight judges and two lawyers, and its brief was AI-assisted false claims and fabricated evidence in litigation. Its output is a recommended framework, not a rule already in force, which matters for how counsel should treat it.

Three routes, and none of them is a fine

The task force framework gives a court three levers when a filing rests on fabricated authorities. First, the court may shift some or all litigation costs onto the party whose fake citations wasted the court's and the opponent's time. Second, the court may restrict oral argument on the tainted brief and record the falsity directly in the judgment, so the fabrication becomes part of the permanent, public case record. Third, the court may refer the responsible lawyer to the Korean Bar Association (대한변호사협회) for possible disciplinary action.

That third route is the one working lawyers should weigh most carefully. A discipline referral is a reputational and licensing risk that a one-time cost order is not. The second route compounds it. A finding that a filing contained fabricated authorities, written into the judgment itself, produces a durable public record that any future opponent, client, or regulator can read. In a system where the same lawyers appear before the same courts, that record follows the practitioner rather than expiring with the case.

The framework also does not draw a line between negligent and deliberate fabrication in the way a single fine schedule would. It hands the court a graduated set of tools and lets the bench decide how far to go, which means a lawyer cannot price the risk in advance as a fixed cost of doing business.

A separate bill would add money penalties

The task force framework and the money penalties are two different things. On July 5, 2026, Rep. Lee Sung-yoon of the Democratic Party proposed amendments to the Civil Procedure Act and the Criminal Procedure Act. As reported, those bills would allow fines of up to 5 million won, roughly 3,270 US dollars, against a plaintiff, representative, or lawyer who submits documents containing fabricated precedents or nonexistent case numbers. The bills are proposed, not enacted, and the specific bill numbers could not be independently confirmed. Treat both the fine amount and the statutory fine route as proposed, not as current law.

The task force also floated a practical tool: a "fake case-number check" feature on the judicial information portal (사법정보공개포털) that would let filers confirm whether a cited case number is real before submission.

What it does not do yet

None of this is binding today. The cost-shifting, judgment-notation, and bar-referral triad is a recommended framework, and the fines live in bills that have only been introduced. There is a gap the reporting makes explicit: forged physical evidence can already be prosecuted under existing criminal law, but no current statute squarely addresses fabricated precedents or invented case numbers in filings. That gap is exactly what the proposals aim to close. Until they advance, courts would be applying general cost and discipline powers rather than a purpose-built rule.

The cross-border read for US counsel

For a US litigator, this is the Korean answer to the same problem that produced Mata v. Avianca and the growing body of US AI-sanctions decisions and standing orders. The instructive difference is the mechanism. US courts have leaned on Rule 11 monetary sanctions and show-cause orders. Korea's proposed routes are cost-shifting, a bar-discipline referral, and a falsity finding written into the judgment text itself. That last mechanism is a reputational sanction that travels with the lawyer and the case, and US counsel coordinating Korean matters may underestimate it precisely because it is not a headline dollar figure. The underlying professional duty is identical in both systems: a human must verify that every cited authority exists before it reaches the court.
