A dramatic family feud over the inheritance of a prized Oregon winery has concluded with a landmark penalty for the misuse of artificial intelligence in court proceedings, exposing deep rifts between siblings and raising serious questions about legal ethics in the digital age.
Valley View Winery, founded in 1972 by Frank Wisnovsky and his wife Ann, faced sudden change when Frank died. Ann continued operating the winery with assistance from her two youngest sons, Mark and Michael, who managed grape cultivation and wine sales while she handled finances and property ownership.
The four Wisnovsky children—oldest Robert, second-oldest Joanne Couvrette, and younger brothers Mark and Michael—were originally set to receive equal stakes in Valley View after their mother’s death. However, in 2016, Ann modified her will to grant full ownership of the business exclusively to her youngest sons. This decision ignited simmering tensions, particularly with Couvrette, who had never returned to the winery after leaving for college, unlike Robert who had briefly helped run the business.
In 2019, Couvrette filed a new estate plan with Ann that would transfer winery ownership to herself and Robert, simultaneously moving her mother to live near her in Southern California. Two years later, she escalated the conflict by suing her younger brothers for $12.6 million, accusing them of manipulating their mother in earlier inheritance arrangements. The brothers counter-sued, alleging Couvrette was attempting to steal their inheritance. After Ann’s death in 2023 amidst ongoing court proceedings, the legal battle intensified dramatically.
Couvrette hired lawyer Steve Brigandi, who agreed to represent her for free because she was dating his son. However, this arrangement proved disastrous when court documents filed by Brigandi were found to be riddled with false, AI-generated citations that were irrelevant to the case or complete hallucinations.
Citing persistent AI misuse in Couvrette’s court filings, the judge dismissed her case against her brothers and imposed a nearly $100,000 fine on Brigandi. The penalty was described as particularly onerous compared to other punishments for AI use in court, with the judge declaring the Valley View Winery case ‘notorious’ and criticizing Couvrette and her lawyer for not being ‘forthcoming, candid, or apologetic about their conduct.’
