Estonia: Tallinn Administrative Court is reported to have fined ten complainants in a felling-permit case over a document drafted with AI that cites the work of scientists who do not exist; the fines of 150 and 50 euros are reported in force in June 2026
According to Delfi Ärileht and ERR (both 26 June 2026), complainants who went to the Tallinn Administrative Court to contest a felling permit sent the court a document that cited scientific work on the effects of clear-cutting. The court found that the Estonian scientists named in the references do not exist and that the studies described could not be found. It asked the complainants how the document had been produced, gave them the chance to submit the cited works, and warned that it could fine them for attempting to mislead the court. The complainants replied that using AI is not forbidden and that they had not meant to mislead the court. The court fined one complainant 150 euros and nine others 50 euros each, saying that complainants are responsible for the accuracy of what they submit. Delfi Ärileht reports that the Tallinn Circuit Court agreed with the administrative court and that the Supreme Court declined the case that week, so the fines are in force. No report names the AI tool.

AI system as recorded: Unidentified AI tool with which, according to the reports of the court's ruling, the complainants' document was drafted; the document cited scientists who do not exist
What Happened
The document. Delfi Ärileht and ERR report that the complainants went to the Tallinn Administrative Court to contest a felling permit and sent the court a document citing scientific work on the effects of clear-cutting. The court found that the Estonian scientists named in the references do not exist and that the studies described could not be found. Delfi Ärileht describes the document as drafted with the help of AI, and ERR says the complaint contained false statements created by AI.
The court's steps. The court asked the complainants to explain how the document had been produced. It gave them the chance to submit the cited works as written evidence and warned that it could otherwise fine them for attempting to mislead the court. The complainants replied that using AI is not forbidden and that they had not meant to mislead the court.
The fines. The court fined one complainant 150 euros and nine other complainants 50 euros each. It said complainants are not forbidden to use AI, that AI is generally known to produce misleading or false information, and that complainants are responsible for the accuracy of what they submit to the court. Delfi Ärileht reports that the law allows a fine of up to 3200 euros.
Appeals. The Tallinn Circuit Court agreed with the administrative court. Delfi Ärileht reports that the Supreme Court declined to take the case that week and that the fines are now in force. It adds that Estonian courts had warned parties about careless AI use before and that no other case of a fine is known.
Limits. Both reports give the same account of the case, and the rulings themselves were not read. The reports do not name the AI tool, say which of the complainants used it, or give the dates of the document and of the rulings.
Reported harm
A court fined one complainant 150 euros and nine others 50 euros each for submitting a document, drafted with AI, that cited scientists who do not exist; Delfi Ärileht reports that the Circuit Court agreed with the ruling and that the fines are in force (Delfi Ärileht; ERR for the fines).
Outcome
ResolvedThe Tallinn Administrative Court fined one complainant 150 euros and nine others 50 euros each for the document. The Tallinn Circuit Court, hearing the appeal against the ruling, agreed with the administrative court. The Supreme Court declined to take the case in the week of the 26 June 2026 reports, and the fines are in force (Delfi Ärileht; ERR for the fines).
What remains unknown
- Which AI tool was used and which of the complainants used it.
- The dates on which the document was submitted and the fines were imposed.
- The outcome of the felling-permit dispute itself.
- The case numbers and full reasoning of the three courts.

Kodiak, Alaska: a hunter reported to have relied on a Google AI answer that snipe season opened on 1 September hunted three snipe before the 8 October opening, reported the violation to wildlife troopers and was fined $150
Alaska Beacon reported on 28 September 2026 that a Kodiak woman hunted snipe illegally on 5 September after a Google search for snipe season told her the season began on 1 September, according to a wildlife trooper's affidavit attached to a citation filed at the Kodiak district court. The outlet describes the answer as a Google AI overview. She hunted three snipe, grew suspicious on learning that duck season did not open until 8 October, checked the regulations and called troopers to report herself. The outlet reports the trooper said he ran an identical Google search and received identical incorrect information. She pleaded no contest and was fined $150, and told the outlet she felt shame and embarrassment. A Department of Public Safety spokesman said it was the first time he thought the agency had seen AI cited, and that she had acted correctly once she learned of the mistake. Google did not respond to the outlet's request for comment.
Rennes administrative court fines a claimant 500 euros for an abusive tax appeal it found manifestly written with an AI tool and too imprecise to assess
According to Gossement Avocats, which quotes the order, and the court's vice-president on France Inter, an order of 19 August 2026 (n°2508168) of the tribunal administratif de Rennes rejected a claimant’s application contesting a VAT reassessment and fined the claimant 500 euros for an abusive application. As quoted by Gossement Avocats, the order says the application had manifestly been written with an artificial intelligence tool and that its grounds lacked the most elementary details needed to assess them. The court also found it inadmissible because no prior complaint to the tax service was shown, and noted that it repeated a request with substantially the same object rejected in October 2025. The court’s vice-president cited the case on France Inter; commentators stress that AI use alone was not the basis for the fine.
Fee suit against the City of Aberdeen (N.D. Miss.): four attorneys on both sides sanctioned after AI tools produced fabricated case citations; trial cancelled and both litigants left without counsel
In a fee dispute between a Louisiana attorney and the City of Aberdeen, Mississippi, briefs filed for both sides in late 2025 cited six cases that do not exist. The attorneys admitted the citations came from unverified AI use: the plaintiff's out-of-state counsel, Kathleen M. Wilson, drafted her filing with an AI drafting program called 'First Drafts', and the City's out-of-state counsel, Kathryn Y. Williams, used an in-house AI legal research tool. Senior Judge Sharion Aycock stayed the case and cancelled the March 2026 trial, then on 8 June 2026 revoked both attorneys' pro hac vice admissions, barred them from the district for two years and fined them $2,500 and $3,500, and disqualified and fined the two local counsel who had signed the filings. Both litigants were left without counsel and given 60 days to find new representation.
Miami: scammers cloned immigration attorney Ángel Leal's face and voice with AI to defraud immigrants seeking legal help
From around October 2025, criminals used AI to clone the image, voice, name, signature and firm logo of Ángel Leal, a long-established immigration attorney in Doral, Florida. They created fake videos, look-alike websites, forged contracts and even fabricated Zoom 'immigration hearings' to persuade immigrants to pay for legal services Leal never provided. Immigrants were defrauded of money, and some believed their cases were progressing when they were not; Leal received one to two defrauded callers a day, changed his phone number, hired an anti-piracy firm that removed thousands of fake profiles and videos, and reported the fraud to local police and federal authorities.
