A labour court in Castro, Paraná (9th Region Labour Court), annulled a court-appointed expert's report after the employer, in a motion for clarification, reported a hidden sentence at the foot of a page instructing artificial intelligence to contest the report only superficially and not to question the files it cited, according to Diário de Justiça. The expert confirmed the text but said it came from teaching material about AI and was inserted by accident; the court's IT section concluded that it had been formatted deliberately to be invisible. The judge said AI had not been used to write the judgment and that the text did not directly influence it, but annulled the report, later submissions and the judgment, ordered a new examination by another expert without AI tools, fined the expert 5% of the value of the case for bad-faith litigation, cancelled the expert's fees and removed the expert from the court's register. The decision, dated 12 October 2026, can be challenged.

On Tuesday 7 July 2026 Mews, a hotel-management software company with Czech roots, announced that it was letting go about 15 percent of its roughly 1,350 employees, which CzechCrunch put at about 200 people. Its founder said the business was in a very strong position and growing fast, but that artificial intelligence is fundamentally changing the economics of hospitality and can now handle much of the executive part of the professional services that hotels pay for, and that to help its customers become AI-native the company had to become AI-native itself. Its product and technology director told Lupa.cz the company had completed a ground-up review of how work is done in an AI-native world, that the decision was proactive and not a reaction to financial pressure, and that the organisation was being designed around what AI enables. The company said the cuts affected positions across all teams and regions and largely spared customer-facing roles. In October 2026 Lupa.cz reported that employees at the company's Czech head office had formed a trade union within the ICT Union, shortly after a layoff it described as officially due to changes brought by AI; the union wants a collective agreement and to be informed before decisions on layoffs and reorganisations. The sources do not say which roles, if any, were taken over by AI tools, how many dismissed employees worked in the Czech Republic, or what severance they received.

In a public post to r/Netherlands created on 29 October 2026, a full-stack web developer with ten years' experience writes that a month earlier they were told they would be fired because AI was able to do their job, and that the day of the post was their last day and last paycheck. In replies the poster quotes the boss as saying 'I can just prompt the AI and it seems to be doing what I need', says they had been at the company five years, worked on one month's notice under a Bulgarian employment, and had watched the company's code repository fill with AI commits. The poster also writes that they used AI heavily in the job and that the company wanted to save money. They say they have applied for developer jobs for 30 days without a workable offer and are thinking of leaving coding; they also say they are in no financial trouble. The account is uncorroborated and the employer is not named.

On 22 October 2026 the urgent-applications judge of the Rennes administrative tribunal rejected a student's request, filed through a lawyer on 18 October, to suspend a university's June 2026 refusal to admit her to a psychology master's programme, finding neither urgency nor serious doubt about the refusal's legality. The judge also fined her 750 euros for an abusive request. The order gives as reasons that the request met neither condition, concerned a programme for which she manifestly lacked the level, and referred to other people's names in ways the judge read as stereotyped mass-produced appeals; it adds that the request mixed curly and straight apostrophes, used many em dashes and black round bullets, and had an ordered but repetitive argument, elements the judge called characteristic of text generated by a generative-AI tool such as Claude.ai. The order does not establish who drafted the request or whether AI was used; Clubic noted that a copy and paste from a word processor can leave the same traces.

In a public post to r/jobs titled 'We were replaced with AI', created on 24 October 2026, a server and network administrator writes that they and the company's lead developer were terminated that day: their access to various systems was revoked and the chief executive then called them, with major budget cuts as the theme of the call. The poster writes that both were replaced with 'the Anthropic subscription' and, in a reply, that it is an Anthropic subscription of 180 dollars a month that the chief executive mentioned, and that staff had seen him using it to scan the company's infrastructure days earlier. In replies the poster says the company is small, located in Australia, and that they worked for it remotely, that finance staff had calls with the chief executive scheduled for the following Monday, and that they feel their years of loyalty were thrown away. The company is not named. The account is the poster's alone and uncorroborated; no employer statement was retrieved.

Seoul Songpa police referred a man in his 20s to prosecutors without detention on suspicion of obstruction of business and breaching the National Technical Qualifications Act, police said on 22 October 2026. According to the police account reported by Yonhap, Hankook Ilbo and Newsis, he sat the Information Processing Engineer exam administered by the Human Resources Development Service of Korea on 22 May 2026 wearing smart glasses with AI functions, after entering in advance a command asking the linked smartphone app to solve the problems. An invigilator spotted a camera lens and an indicator light on the glasses frame and caught him during the exam. Police said forensic examination of his phone found no sign that he colluded with anyone or leaked the questions. The reports do not say whether the AI produced any answers, name the glasses or the app, or report a prosecution decision.

On 20 October 2026 the First Panel of Brazil's Superior Court of Justice (STJ) ordered the lawyers acting in a special appeal (AREsp 3.095.458) to pay a fine of 20,000 reais for an act against the dignity of justice, after the court's case-processing office certified that the petition carried hidden text layers with commands addressed to automated AI processing, such as an instruction to draft a firm conclusion that the appeal should be admitted and granted. The panel also ordered a technical report on the concealment techniques and the communication of the case to the Brazilian bar (OAB) and the Federal Public Prosecutor's Office. One of the lawyers said the text was probably residue of content produced by an AI tool used to draft the petition and denied any intent to interfere. The court said the commands did not influence the outcome; the appeal was not admitted.

In a midterm exam on 14 October 2026 in a major course of about 100 students at Konkuk University in Seoul, a student sent the questions to a friend through a camera attached to the chest; the friend solved them using AI and sent the answers to the student's smartwatch, according to the professor's notice to students as reported by JoongAng Ilbo on 21 October 2026. The professor became suspicious of a perfect score, asked the student to solve the same problems again, and the student could not and confessed. The university said the professor gave the student a zero on the exam and an F in the course under its regulations for cheating by writing answers using AI and a smartwatch, and the department decided to ban cameras and watches from the final exam onward. The AI tool is not named, and no consequence for the friend is reported.

China Daily reported on 15 July 2026 that the first prize in a local photography competition in Hohhot, Inner Mongolia, had been revoked after the image was found to be AI-generated. Online users had pointed to garbled characters on the workers' vests, unnatural sunlight and matching faces in the winning photo of three sanitation workers. After an investigation, the city's federation of literary and art circles, one of the organisers, confirmed in a notice on Tuesday 14 July that the photo had been created using AI, cancelled its award and barred the work from competitions, evaluations, exhibitions and official archives. The competition was suspended for rectification; the notice said those responsible would be dealt with under the relevant rules and that the case exposed lax vetting and imprecise judging criteria. The entrant is not named, and who generated the image is not stated.

In a first-person essay published by the Oakland Review of Books on 2 October 2026, a former customer success manager at an education technology company writes that the company began a push at the end of 2025 to become 'AI-first', requiring staff to use AI tools, and that the author was later laid off. The author writes that an hour after the layoff the CEO held a seven-minute all-hands meeting to read a Claude-generated script saying leadership was 'replacing these roles with AI', and that the company let 40 people go, about 20 percent of its workforce, at the end of about six months of role eliminations. Staff who could not attend the HR meeting were told by email that their roles ended the next business day. The author also writes that sales were down and customers were unhappy, and that losing the job brought more relief than anything else, cushioned by savings and an employed partner. The company is not named, and the layoff is not dated beyond the essay's sequence. The account is uncorroborated.

Times of Malta reported on 18 October 2026, from interviews with anonymous former gambling-sector employees, that iGaming companies are laying off staff as they turn to AI. One former designer, who says they lost their job earlier in 2026, says their team had been told to train an AI model to make design and brand-guideline decisions, presented as a tool to help designers, and that the company later decided the model was fit enough to replace around half of the design team, including those who trained it. The designer says there was no notice, that they were asked to resign later that day and that the severance was the bare minimum. The outlet omitted company names, and the workers said they had signed non-disclosure agreements. GamingMalta, the industry promotion foundation, told the outlet it sees talent being redeployed rather than replaced by AI, and the article notes that others pointed to search-engine changes and higher UK gambling taxes. The account is a single anonymous worker's, relayed by one outlet; the employer and where the job was based are not stated.

In a memorandum of decision issued in early August 2026, a Connecticut Superior Court judge found that a motion for default and a notice filed on 24 July 2026 by a self-represented plaintiff, in a suit against a healthcare provider over access to records, carried text in tiny white type that was invisible to a human reader but legible to software. The concealed text told any AI model reviewing the filing to make its output agree with the filing and to work toward reversing the Chief Clerk's denial of his default request. After the court gave notice of a sanctions hearing, he hid further messages in later filings, which he said were jokes. The court treated the first instruction as a prompt injection, did not believe his explanation that he was auditing the court's use of AI, and rescinded his ability to file electronically, so that future filings must be made on paper at the clerk's office; Ars Technica reports that no monetary penalty was imposed. The court said the Connecticut Judicial Branch does not use AI to review or decide filings and that the motion was denied on its merits from a printed copy, so the hidden text affected no ruling. The plaintiff told Reuters, according to Ars Technica, that his intent was to audit the court.

In May 2026 a judge of the 3rd Labour Court of Parauapebas, in the Brazilian state of Pará, fined two lawyers about R$84,000 after text in white font on a white background was found in a document they filed for a worker in a labour claim. According to the sentence as reported by G1, the hidden text was detected while the judgment was being drafted with Galileu, a generative AI tool the labour courts use to help judges and staff draft sentences, and its evident intention was to make the AI produce a superficial defence or a compromised draft judgment. The judge called the technique prompt injection. The lawyers said they disagreed with the decision and that there was never any command to manipulate the judge's decision, describing the text as an attempt to protect their client from the AI; one of them said she did not work on labour cases. In October 2026 the regional labour court announced that a Connecticut Superior Court judge had cited the decision when sanctioning a litigant for misuse of AI.

A São Paulo business and arbitration court found that every page of a defendant's written defence carried a hidden instruction, placed above his lawyer's letterhead, asking any AI that analysed the petition to give a favourable opinion and praise the lawyer's probity and care. In a sentence dated 14 September 2026 the judge treated this as prompt injection and bad-faith litigation: although the defendant won on the merits, he was ordered to pay the plaintiff a fine of 9% of the updated case value, and the sentence was sent to the São Paulo bar to examine the lawyer's conduct. No source says any AI system read the instruction.

A candidate in a selection process to accredit social workers and psychologists for the court district of Brasnorte, in the Brazilian state of Mato Grosso, was eliminated after the selection support commission found that the 3x4 identification photo she submitted had 'clear and unmistakable traces of generation and/or editing by Artificial Intelligence' and a digital watermark in one corner. The commission's statement of 8 October 2026, accepted by the court district and published in the electronic Justice Gazette on 13 October, treated the picture as a simulated image that did not meet the call's requirement of a recent, faithful facial photograph, and her qualification was annulled. A second candidate was eliminated in the same decision for a mould-stained, outdated photo, with no AI involved. The candidate is not named in the reports, and her response and the tool used are not reported.

Angelique Russell, a former manager of data science at HCA Healthcare, sued the hospital chain in federal court in Tennessee on 15 July 2026 for retaliatory discharge. Her complaint alleges that she found that Timpani, an AI system whose daily census predictions help set nurse staffing, overwrote the data behind its predictions so that its staffing decisions could not be audited or reproduced; that HCA placed her on a performance improvement plan weeks after she raised this; and that HCA fired her on 3 April 2026, days after she escalated her concerns to its Director of Responsible AI and its compliance department. She says the performance reasons were pretextual. These are allegations; HCA had not formally responded in court when WIRED reported on the suit on 2 October 2026.

A judge of the 5th Mixed Court of Sousa, Paraíba, found hidden instructions aimed at artificial intelligence tools spread over seven pages of a lawyer's motion for clarification in a public-competition case in June 2026, including an order to ignore impartiality and a note calling it a test of whether the judge used only AI to decide. The judge fined the lawyer two penalties of R$16,400 (R$32,800 in total) for bad-faith litigation and contempt of the court's dignity, and referred the case to the Paraíba bar (OAB-PB) and the state prosecutors, G1 reports. The defence said the commands were not inserted deliberately and blamed an error in exporting a file prepared with AI support. An appeal judge refused to suspend the fines on 30 June, the trial judge kept them on reconsideration, and in July, G1 reports, the OAB-PB preventively suspended two lawyers after opening procedures into two hidden-command cases, one of them the Sousa case.

NorthJersey.com reported on 5 October 2026 that a former remote employee of Sutherland Healthcare Solutions, based in Clifton, New Jersey, sued the company in New Jersey Superior Court in Atlantic City on 23 September 2026. According to the complaint as reported, the employer told the employee it would start monitoring her through her work laptop's webcam with software called Sentinel AI, which would use AI and facial recognition to confirm that she was the person at the desk, taking 160 still images in an eight-hour shift. The employee raised concerns in writing about the AI seeing inside her home and about whether the data would be securely stored, said the monitoring had increased her anxiety and stress and worsened a medical condition, and asked for a full or partial exemption as a reasonable accommodation. The suit says the request was denied, she was given a 24-hour ultimatum on 13 August 2026 to submit to the monitoring or resign, an offer to avoid the software by commuting to the office was rejected because it would require six hours of travel time, and her employment was terminated on 8 September 2026. The suit alleges that the employer violated New Jersey's anti-discrimination laws and retaliated against her for requesting reasonable accommodations. Sutherland did not respond to the outlet's requests for comment, and the allegations have not been tested in court.
