Matter of M.S. (M.H.)

What happened

In an Erie County child protective proceeding, the county relied on 3 videos bearing 2019 timestamps that appeared to show a mother's live-in boyfriend abusing her 14-year-old daughter. The videos had been recovered during an FBI investigation from the computer of a man who said he had hacked into the family's home security cameras. Neither that man nor the boyfriend testified.

Family Court admitted the videos, largely on testimony that details in them matched the family's home, and found that the mother had abused and neglected her children. The Appellate Division, Fourth Department, affirmed, reasoning that doubts about the videos went to their weight rather than their admissibility.

What the court did

On February 17, 2026, the Court of Appeals reversed in an opinion by Chief Judge Wilson, joined by Judges Rivera, Cannataro and Halligan. The majority concluded that the videos had not been properly authenticated. It wrote that "the increasing prevalence of 'deepfake' videos has only rendered the method of matching circumstantial details in a video to personal observations a more suspect form of authentication." The disposition reads: "Orders reversed, without costs, and petitions dismissed."

Judge Troutman dissented, joined by Judges Garcia and Singas, writing that the majority "creates new and perhaps insurmountable hurdles for future authentication of video evidence." Judge Singas wrote a separate dissent, joined by Judge Garcia, disputing that technology available in 2019 could have produced such videos. The majority made no finding that the videos were fabricated. It ruled that their proponent had not shown they were what they purported to be.

Where it stands

The decision is final and is reported as 2026 NY Slip Op 00825. The opinion and both dissents are available from the New York State Law Reporting Bureau.

The obligation it engaged

No professional in this matter used an AI system. The case is included because it addresses the question every expert who handles recordings now faces. A video's resemblance to a real place does not show that the events in it occurred. The majority's reasoning tracks Independent authority: a recording's content cannot vouch for itself, and the chain from device to court has to be confirmed from sources outside the file.

For a forensic examiner, the practical consequence is a custody and provenance record that begins at the source device. The governing test asks whether a competent examiner, working from primary sources, could reproduce the conclusion that a recording is genuine. Where the only people who could speak to the recording's creation are absent, that test is hard to meet.
