Florida Judge Peffer Suspended Over a Deepfake Recording: How Fake Audio Is Fought in a Criminal Case

A judge sending a newspaper a fake phone call between Florida Supreme Court justices sounds like politics. It’s also a clean example of something that now comes up in criminal cases: a recording that sounds real, comes from someone who wants it believed, and was never checked. Faked audio is cheap to make now, and a recording offered in a Florida criminal case has to clear an authenticity requirement before the jury hears it.

What the Court Did

In Inquiry Concerning a Judge (Lauren Nichole Peffer), JQC No. 2025-001, No. SC2025-0647 (Fla. Oct. 9, 2026), the Florida Supreme Court approved the findings of its Judicial Qualifications Commission (the JQC, which investigates complaints against judges) and imposed discipline. Judge Peffer sits on the Seventeenth Judicial Circuit bench in Broward County.

In a 2024 interview with the South Florida Sun Sentinel, she spoke of an “image crisis within Florida’s judiciary” and pointed to a book by a former Ninth Circuit employee. The court says she “had in fact never read the book and later admitted that she took no steps to authenticate the veracity of any statements therein.” Asked whether she had evidence for the book’s claims, she “sent the interviewer a recording of a supposed conversation between justices of this Court and the Ninth Judicial Circuit chief judge.” The court called it “a fabricated and fake telephone conversation.”

News reports on the JQC’s May 2025 charges add that the recording was “likely” made “using computer manipulation or generative-AI,” and that the charges said she didn’t “exercise due diligence to ascertain whether the recording was fabricated before using it publicly.” The order itself doesn’t say how the recording was made.

The court applied Canon 7A(3)(b) of the Florida Code of Judicial Conduct, which says a judicial candidate “shall maintain the dignity appropriate to the judicial office and act in a manner consistent with the impartiality, integrity, and independence of the judiciary.” She admitted the violation but said it was unintentional. The court answered: “Intentional or not, her conduct undermined public confidence in the integrity of the judiciary,” because she “failed to verify the accuracy of the book or recording on which she relied.” It fined her $10,000, suspended her for 30 days, ordered a public reprimand and ordered her to pay costs. Justices Muñiz and Francis recused.

Why Fake Audio Is a Courtroom Problem

The judge’s case was a disciplinary matter, not a criminal one. Still, the court’s criticism is the same one a defense lawyer makes about a recording in a criminal case: nobody checked where it came from.

A complainant produces a voicemail and says it’s a threat. A witness plays a recorded call and says it’s a confession. In each, the case may rest on a file that someone on one side made, kept and handed over, and the law makes the side offering it show it’s genuine.

What Section 90.901 Requires

Florida’s Evidence Code puts the rule in one short section. Section 90.901 reads in full: “Authentication or identification of evidence is required as a condition precedent to its admissibility. The requirements of this section are satisfied by evidence sufficient to support a finding that the matter in question is what its proponent claims.”

“Proponent” means the side offering the evidence, usually the prosecutor. “Condition precedent” means it has to happen before the jury sees or hears the item. And section 90.105(1) says “the court shall determine preliminary questions concerning … the admissibility of evidence,” so the judge decides whether the foundation was laid.

The bar is a low one. The proponent doesn’t have to prove the recording is genuine beyond doubt. The proponent has to offer enough that a fact-finder could find it genuine. The statute says nothing about AI, so the same words cover a voicemail and a file someone may have synthesized.

Florida appellate courts enforce it. In Santana v. State, 191 So. 3d 946 (Fla. 4th DCA 2016), a drug-trafficking case, the State played recorded calls between the defendant and a confidential informant. The agent couldn’t testify that the recordings were true representations of what was said, and the informant didn’t testify. The Fourth District wrote that the State “did not introduce evidence that the recording was a fair and accurate representation of the conversation that occurred,” and held that admitting the recordings “without this foundation was an abuse of discretion.” Id. at 948. Identifying the speakers wasn’t enough on its own.

The Original File and Copies

A second set of rules governs the recording itself. Section 90.952 says that, “[e]xcept as otherwise provided by statute, an original writing, recording, or photograph is required” to prove the contents of the recording. Section 90.951(3) defines an original of a recording as “the writing or recording itself,” and says that if data is stored in a computer, “any printout or other output readable by sight and shown to reflect the data accurately is an ‘original.’”

Section 90.954 lets in other evidence of the contents when, among other things, “all originals are lost or destroyed, unless the proponent lost or destroyed them in bad faith.” That matters when the State offers a forwarded clip or a screen recording and the original is gone. Who lost it, when, and why becomes the question.

What the Defense Asks For

Where a recording is part of the case, a defense lawyer asks early, and in writing, for these things.

The original file, not a copy. That means the native file from the device or account where it was first saved, with its metadata (the data inside a file that records things like when it was created and what software touched it).

Who made it and who kept it. The person who recorded the call, the device used, and every person and system that handled the file between the recording and the courtroom. That’s the chain of custody, the record of who held the evidence and what they did with it. A gap in the chain is where an edit can hide.

Who is on it. The State has to link the voice to the accused. Recognizing a voice isn’t a verified match, and a synthetic voice is built to sound familiar.

A forensic examiner. When the file matters to the case, a qualified digital forensics examiner can look at the file’s structure, its history and signs of editing or synthesis. The firm’s page on digital forensics defense in Florida covers how that work fits into a case, and the forensic science defense page covers how the State’s other scientific evidence gets tested.

A foundation hearing. If the State can’t put a witness on the stand who can say the recording is a fair and accurate account of what was said, Santana is the argument that the recording stays out. The firm’s earlier post on AI chats and Florida’s written threats law covers a related question.

Judge Peffer’s order faulted her for using a recording without verifying it. The same standard is fair to ask of anyone who offers one against a person accused of a crime.

Common Questions

Can the State use a recording in a Florida criminal case without authenticating it?

No. Section 90.901 makes authentication a condition of admissibility. The proponent has to offer evidence sufficient to support a finding that the recording is what the proponent says it is. In Santana v. State, 191 So. 3d 946, 948 (Fla. 4th DCA 2016), the court held that admitting audio recordings without a foundation as to their accuracy was an abuse of discretion.

Does Florida have a special rule for deepfakes in criminal trials?

Section 90.901 doesn’t mention AI or deepfakes. The general authentication rule applies to every recording, and a defense lawyer tests a suspect file with the same tools: the original, the metadata, the chain of custody and a forensic examiner.

What did the Florida Supreme Court do to Judge Peffer?

On October 9, 2026, it suspended her for 30 days, fined her $10,000, ordered a public reprimand and ordered her to pay the costs, for violating Canon 7A(3)(b) of the Code of Judicial Conduct while she was campaigning in 2024.

Was the recording in the Peffer case made with AI?

The court called it “a fabricated and fake telephone conversation.” The JQC’s charges, as reported in May 2025, said it was likely made with computer manipulation or generative AI. The order doesn’t say how.
