NJ Brady-Giglio Policy: Disclosure, Sources, and Remedies

New Jersey’s Brady/Giglio policy requires prosecutors to turn over any evidence favorable to the defense and any information that could undermine the credibility of a testifying law enforcement officer, whether or not the defense asks for it. The framework comes from two U.S. Supreme Court decisions, Brady v. Maryland and Giglio v. United States, and is implemented statewide through Attorney General Law Enforcement Directive 2019-6 and the Department of Law and Public Safety’s disclosure policy.¹

What Prosecutors Must Disclose

Two kinds of material fall within the duty. The first is any evidence favorable to the accused that is relevant to guilt or punishment. The second is impeachment evidence that could cast doubt on a government witness, which for most criminal cases means a police officer.

Directive 2019-6 identifies nine categories of information about a law enforcement officer that may qualify as Giglio material and must be gathered for possible disclosure:²

A sustained finding that the officer filed a false report or submitted a false certification in any matter, professional or personal.
A sustained finding of untruthfulness or lack of candor.
Any pending criminal charge or conviction, including disorderly persons offenses and driving while intoxicated.
A sustained finding that contradicts the officer’s claimed educational achievements or expert witness credentials.
A judicial or administrative finding that the officer was intentionally untruthful.
A sustained finding that the officer intentionally mishandled or destroyed evidence, failed to follow collection procedures, or disregarded forensic protocols.
Any pending investigation involving allegations of dishonesty, bias, or integrity.
Information suggesting the officer may be biased for or against a party in the case.
A sustained finding that the officer is biased against people based on gender, gender identity, race, ethnicity, or similar characteristics.

The list is not exhaustive. Prosecutors are expected to consider other conduct that bears on an officer’s reliability as a witness even when it does not neatly match one of the nine categories.²

The duty applies whether the defense makes a specific request, a general request, or no request at all. In United States v. Bagley, the Supreme Court held that the constitutional obligation to disclose is the same in each situation.³ New Jersey follows that rule.¹

When and How Disclosure Happens

Brady and Giglio material moves through the ordinary discovery process under New Jersey Court Rule 3:13-3.¹ The prosecution must provide discovery within seven days of the return or unsealing of an indictment, absent good cause for delay.⁴ That window covers physical evidence, witness statements, scientific reports, police reports, and exculpatory information, and the officer-history disclosures travel through the same channel.

The prosecutor decides the extent and manner of disclosure. Redactions are routine to protect the privacy of third parties and the officer, and prosecutors typically seek protective orders restricting how the defense may use the information.¹

After disclosure, the prosecutor must notify a designated liaison within the officer’s law enforcement agency and provide any court filings related to the impeachment information. The liaison then informs agency leadership and the officer that a disclosure was made and what was shared.

The obligation is continuous. It begins when charges are filed and runs through the end of proceedings, so evidence that surfaces later in the case still has to be turned over promptly.

Where the Officer Information Comes From

Most Giglio material about police officers originates in internal affairs files. New Jersey’s Internal Affairs Policy and Procedures requires every law enforcement agency to maintain an internal affairs function, accept misconduct complaints from any source, and investigate allegations promptly and objectively.⁵

A sustained finding — one where the evidence shows the officer violated a law, regulation, policy, or procedure — is the usual trigger for disclosure. But pending investigations into truthfulness, bias, or integrity also qualify under the directive. That means a prosecutor may have to disclose information before the internal investigation is resolved.²

Internal affairs records are retained for long periods so the material stays available. Files involving criminal matters that led to an officer’s arrest are kept for 75 years, and other investigative records are maintained for the officer’s entire career plus five additional years.⁵

How Far the Duty Reaches

The prosecutor’s responsibility extends beyond the files sitting on their own desk. In Kyles v. Whitley, the Supreme Court held that the prosecutor has a duty to learn of any favorable evidence known to others acting on the government’s behalf, including police officers from other agencies working the same case.⁶ If a multi-agency task force investigates a case, the lead prosecutor is responsible for the full set of files.

Not every omission is a constitutional violation. Courts apply a materiality test: evidence is material only when there is a reasonable probability that disclosure would have changed the outcome. Reasonable probability does not require a showing that acquittal was more likely than not; it requires enough probability to undermine confidence in the verdict.³ Courts assess the suppressed material together, not piece by piece, so items that look minor in isolation can be material in combination.

Good faith is not a defense. The original Brady decision established that the prosecutor’s state of mind is irrelevant: if material favorable evidence is suppressed, the defendant’s due process rights are violated regardless of intent.⁷

What Happens to Flagged Officers

An officer whose history generates ongoing Giglio disclosures can lose much of their usefulness as a witness. If a prosecutor concludes that the officer cannot testify credibly because of past misconduct, the officer may face discipline up to termination. Officers may be reassigned away from investigative work, kept out of situations requiring them to make arrests they would later have to testify about, or passed over for promotion. New Jersey courts have upheld decisions by municipalities declining to rehire officers whose credibility had been compromised by Brady/Giglio issues, and off-duty conduct can carry the same consequences when it relates to truthfulness, bias, or integrity.

Remedies When Disclosure Fails

If a Brady or Giglio violation surfaces during trial, the court can declare a mistrial or bar the prosecution from using evidence the suppressed material would have undermined. Most violations, though, come to light only after conviction, because the defense does not know what it was never shown.

A defendant who later discovers suppressed evidence can seek post-conviction relief under New Jersey Court Rule 3:22. For Brady claims, the petition must be filed within one year of when the defendant discovered, or reasonably should have discovered, the factual basis for the claim. The court then evaluates whether the newly discovered evidence, viewed alongside the full trial record, creates a reasonable probability of a different outcome.

Civil damages are harder to obtain. A person whose conviction resulted from a Brady violation may sue under 42 U.S.C. § 1983, which makes anyone acting under color of state law liable for depriving a person of constitutional rights.⁸ The underlying conviction must first be overturned, because a Section 1983 claim that would call the conviction into question cannot proceed while the conviction stands. Qualified immunity is available to many defendants, supervisory prosecutors generally have absolute immunity from damages for Brady violations, and municipalities can be held liable only under stringent standards. These barriers make Section 1983 recovery for Brady violations uncommon, though the possibility adds a layer of accountability for officers who withhold evidence from prosecutors in the first place.
