New Mexico has made notable strides in law enforcement transparency, particularly in decertification reporting and police accountability reforms. Yet, when it comes to Brady and Giglio compliance—ensuring the disclosure of exculpatory and impeachment evidence—the state’s legal infrastructure remains fragmented, discretionary, and underdeveloped. While prosecutors are bound by clear constitutional obligations, there is no statutory requirement to track or disclose officer misconduct, no centralized Giglio list, and no uniform procedures across the state’s 13 judicial districts. Recent legislative reforms have aimed to improve public access to police disciplinary records, but implementation is uneven and lacks formal integration with prosecutorial disclosure obligations. As a result, officer credibility remains a blind spot in many New Mexico courtrooms, especially in rural and under-resourced jurisdictions.
Criminal prosecutions in New Mexico are handled by 13 elected District Attorneys, supported by the Office of the Attorney General, which handles state-level appeals and may take over high-profile or complex prosecutions. Discovery obligations in criminal cases are governed by:
New Mexico Rule of Criminal Procedure 5-501: Requires the state to provide the defense with any material evidence favorable to the accused.
Rule 3.8(d) of the New Mexico Rules of Professional Conduct: Mirrors the federal Brady standard, requiring prosecutors to disclose all information that tends to negate guilt or mitigate punishment, including impeachment evidence.
Law enforcement officers are certified by the New Mexico Law Enforcement Academy (NMLEA) and subject to oversight by the New Mexico Law Enforcement Certification Board, which has the authority to suspend or revoke certification for misconduct. However, there is no statutory or regulatory mandate requiring the board or police departments to report disciplinary actions to district attorneys. Likewise, there is no state-run database for Giglio-impairing misconduct, and no prosecutor is required to maintain or share a Brady or Do Not Call list.
New Mexico has a long and troubled history with police misconduct, civil rights violations, and excessive force—particularly in departments like Albuquerque Police Department (APD), which has been under a federal consent decree since 2014. The U.S. Department of Justice found that APD engaged in patterns of unconstitutional force and failed to hold officers accountable. Despite these findings, there was no corresponding reform to integrate these credibility concerns into prosecutorial disclosure practices.
Several wrongful convictions and case reversals have occurred due to failures to disclose exculpatory evidence or impeachment material. For instance, in State v. Duarte, the conviction was overturned because the prosecution withheld key evidence about a witness’s criminal history and cooperation with law enforcement. Such outcomes reflect the persistent disconnect between police accountability systems and prosecutorial disclosure obligations.
Recent legislative changes—such as SB 375 (2020), which broadened public access to sustained police misconduct records—signal a move toward greater transparency. Yet these reforms have not been tied directly to Brady or Giglio compliance, and there remains no mandate requiring prosecutors to actively monitor officer credibility or proactively disclose it across cases.
New Mexico’s Constitution enshrines due process and confrontation rights under Article II, Sections 14 and 24, mirroring federal guarantees.
Relevant statutes and rules include:
Rule 5-501 NMRA: Requires the prosecution to disclose any evidence favorable to the accused that is material to guilt or punishment.
Rule 3.8(d) NMRA (Ethics Rule): Requires prosecutors to disclose all information known to them that tends to negate guilt, mitigate punishment, or impeach state witnesses.
New Mexico Inspection of Public Records Act (IPRA): Grants access to public records, including certain police disciplinary records. However, internal affairs files may still be withheld unless discipline is final and sustained.
SB 375 (2020): Requires law enforcement agencies to disclose disciplinary records that result in suspension, demotion, or termination—though not all findings of dishonesty fall under this mandate.
No statute requires the creation or maintenance of a Giglio list, nor does state law mandate that law enforcement notify prosecutors of credibility-compromising disciplinary outcomes.
State v. Trujillo, 2002-NMSC-005: The New Mexico Supreme Court reaffirmed that the prosecution has an obligation to disclose impeachment evidence, even if it’s not directly requested by the defense.
State v. Duarte, 2007-NMCA-012: The court reversed a conviction due to nondisclosure of cooperation agreements between a key witness and the state.
State v. Baca, 1997-NMSC-045: Emphasized that Brady material includes not only evidence favorable to the defense but also evidence that could be used to impeach a witness’s credibility.
Despite these rulings, the judiciary has not imposed systemic requirements for recordkeeping, Giglio tracking, or inter-agency notification.
The New Mexico Law Enforcement Academy provides training in ethics and constitutional law but does not require Brady or Giglio-specific instruction. Agencies are not required to notify prosecutors when officers are found to have committed misconduct related to honesty, bias, or use of force—nor is there any system to flag these individuals before they testify in court.
Internal affairs investigations are typically shielded until they result in final, sustained discipline. Even then, the information is often siloed within the department and not communicated to prosecutors unless specific inquiries are made. Many departments, especially in rural counties, lack formal policies governing disclosure to prosecutors.
Some individual prosecutors—such as those in Bernalillo County (Albuquerque)—have developed informal “Do Not Call” lists, but these are not standardized, publicly disclosed, or coordinated statewide.
There is no centralized body in New Mexico responsible for auditing Brady or Giglio compliance. Complaints against prosecutors are handled by the Disciplinary Board of the New Mexico Supreme Court, but sanctions for Brady-related misconduct are extremely rare.
The New Mexico Law Enforcement Academy Board may decertify officers for misconduct, but this information is not automatically shared with district attorneys. Nor is there any mandate that prosecutors notify other jurisdictions if an officer on a Giglio list transfers or testifies in a different county.
Recent legislation has begun to require the reporting of officer use-of-force incidents and misconduct to the state—but no mechanism yet ties this data to prosecutorial duties or courtroom disclosures.
Albuquerque Police Department DOJ Investigation (2014–Present)
Federal investigators found patterns of excessive force, misleading reports, and poor accountability. Many officers identified in the investigation later testified in court without defense counsel being informed of their conduct history.
State v. Duarte (2007)
The court overturned a conviction where the prosecution failed to disclose that the testifying witness had received favorable treatment in exchange for cooperation. No internal list or system existed to flag such relationships.
Luna County Sheriff’s Office Scandal (2020)
An officer fired for dishonesty and excessive force was later hired by another agency and permitted to testify without disclosure of prior findings. The case revealed the absence of inter-agency communication and lack of prosecutorial tracking.
These cases highlight the systemic gaps in New Mexico’s disclosure infrastructure. Officers with sustained credibility issues continue to testify. Prosecutors often lack full knowledge of their witnesses’ disciplinary history, and defense counsel may remain unaware of impeachment material unless they independently uncover it—usually too late. Even in high-profile cases, there is no guarantee of candid disclosure without persistent legal effort.
No Central Giglio Tracking: Prosecutors are not required to maintain, update, or share lists of officers with credibility issues.
No Mandatory Reporting from Law Enforcement: Police agencies are not obligated to report sustained findings of dishonesty to prosecutors or the courts.
Internal Affairs Records Remain Opaque: Many disciplinary files are not disclosed unless requested through litigation or subpoena.
Lack of Consistent Training: Neither prosecutors nor officers receive mandatory, standardized training on Brady/Giglio disclosure obligations.
Efforts to codify disclosure practices have stalled amid pushback from law enforcement associations and county prosecutors. Attempts to expand public records access—particularly regarding personnel files—have faced legal challenges and administrative inertia. Prosecutorial independence and decentralized police oversight contribute to the lack of a cohesive, enforceable statewide standard.
Create a Statewide Giglio Registry
Require every prosecutor’s office to report and maintain a list of officers with sustained credibility-impairing misconduct, accessible to all prosecutors and the courts.
Mandate Reporting from Law Enforcement Agencies
Require all police departments to notify the relevant District Attorney’s Office within 30 days of any sustained misconduct finding involving dishonesty, excessive force, or civil rights violations.
Integrate POST and Prosecutorial Systems
Ensure that any officer decertified or disciplined by the Law Enforcement Academy Board is flagged for Giglio review and reported to all relevant legal parties.
Update Criminal Rule 5-501
Amend the rule to explicitly require affirmative, pretrial disclosure of all impeachment evidence known to any part of the state’s investigative team.
Amend IPRA to Ensure Disclosure of Sustained Misconduct
Require automatic release of sustained findings related to truthfulness, bias, or rights violations—regardless of privacy exceptions.
Establish a Prosecutorial Oversight Commission
Create an independent board to audit Brady/Giglio compliance, issue public reports, and investigate disclosure failures.
Build a Defense-Accessible Giglio Portal
Allow defense attorneys to request and verify Giglio status of testifying officers via a secure system.
Standardize Disclosure Policies Across Districts
Mandate that every prosecutor’s office develop, publish, and follow a written policy on Giglio material tracking and disclosure.
New Mexico is a state in transition—its public records laws are improving, and its awareness of police misconduct is growing. But when it comes to prosecutorial candor, the gap between principle and practice remains wide. Without centralized tracking, mandatory reporting, and enforced disclosure rules, constitutional guarantees remain aspirational. Justice demands more. Candor in New Mexico must evolve from a matter of ethics into a matter of enforceable law.
