Villanueva v. Las Vegas Metropolitan Police Department is a Nevada federal civil-rights action in which a September 29, 2026 order distinguished discoverable ChatGPT case summaries from protected expert prompts, deposition preparation and draft-report material.[1]

Underlying action

According to the court’s February 17, 2026 order, Jose Villanueva alleged that corrections officer Francis Soriano used excessive force against him while he was detained at the Clark County Detention Center. The court granted the defendants’ dismissal motion in part and denied it in part; it permitted the municipal-liability claim to proceed and granted leave to replead the federal excessive-force claim under the Fourteenth Amendment. The allegations had not been resolved by a liability finding in that pleading-stage order.[2]

September 29 expert-discovery order

The court recounted that expert Tom Melton testified that he used ChatGPT to research and draft his report. Magistrate Judge Albregts had ordered production of his entire 40-page ChatGPT history log. District Judge Traum reviewed the log and partially sustained Villanueva’s objection.[1]

The court required production of the AI-generated case summaries that Melton considered in forming his opinions, treating them as facts or data within Rule 26(a)(2)(B). It protected his questions and prompts, deposition-outline preparation and draft-report material because they revealed mental impressions or fell within draft-report and trial-preparation protections. The ruling applied these distinctions to the particular expert log.[1]

In that context, the court concluded that Melton’s use of ChatGPT as a research, drafting and editing application did not waive otherwise privileged information. It also observed that concerns about his methodology and reliance on ChatGPT could be addressed through impeachment at trial.[1]

The same order overruled objections concerning deferred punitive-damages financial discovery and a requested protective order against requests for admission. It recorded that the defendants’ summary-judgment motions remained pending as of September 29.[1]
