State v. Trevizo: Three-Part Waiver Test for Third-Party Presence and a Narrow Mandatory-Reporting Exception to Physician-Patient Privilege

1. Introduction

In State v. Trevizo (N.M. July 30, 2026), the Supreme Court of New Mexico addressed the scope of the physician-patient privilege under Rule 11-504 NMRA and the circumstances under which that privilege may be lost through statutory reporting duties or waived when third parties (including police officers) are present. The State brought an interlocutory appeal from a district court order suppressing evidence it obtained after hospital staff summoned police to the defendant’s hospital room during an emergent medical event following childbirth.

The central legal issues were: (1) whether mandatory child-abuse reporting under NMSA 1978, Section 32A-4-3(A) (2021, amended 2025) and the “required-by-law-to-report” exception in Rule 11-504(D)(4) eliminated the privilege; and (2) whether the defendant waived the privilege by speaking in the presence of her mother and uniformed police officers. The Court affirmed suppression on privilege grounds and declined to reach the separate Miranda dispute.

2. Summary of the Opinion

The Court held:

  • Mandatory reporting does not create a blanket forfeiture of the privilege. The Rule 11-504(D)(4) exception is narrow and covers only “material” the physician is required by law to report—here, the “matter” of knowledge or reasonable suspicion of child abuse or neglect under Section 32A-4-3(A). Once the hospital notified law enforcement that a deceased infant had been found, the reporting duty was satisfied; privileged communications remained protected beyond that limited report.
  • No waiver occurred despite third-party presence. The Court rejected a per se waiver rule and announced a structured test for waiver-by-third-party-presence requiring: (1) actual knowledge of the third party’s presence, (2) mental and physical capacity to waive, and (3) voluntariness under the totality of the circumstances. On these facts—narcotic medication, profound pain, bleeding, emergent condition, and a “confrontational” disclosure made in the presence of armed officers positioned in the doorway—the defendant lacked capacity and did not voluntarily waive the privilege.

The result: the Court affirmed suppression of “all evidence obtained by the State in violation of the physician-patient privilege.”

3. Analysis

A. Precedents Cited

1) Privilege purpose and application in criminal cases

  • State v. Roper, 1996-NMCA-073, ¶ 6: Trevizo relied on Roper for the classic justification of the privilege— encouraging complete disclosure for diagnosis and treatment “without fear of publication”—and for the proposition that the physician-patient privilege applies in criminal cases, not merely civil disputes.
  • State v. Lucero, 2023-NMCA-035, ¶ 22: The Court reinforced that accurate diagnosis and treatment depend on patients being able to share potentially “embarrassing” or “incriminating” information, anchoring the privilege in patient autonomy and access to care.
  • State v. Gonzales, 1996-NMCA-026, ¶ 14: Cited to acknowledge the privilege is not absolute, setting the stage for examining exceptions and waiver.

2) Standards of review for privilege and waiver

  • Allen v. LeMaster, 2012-NMSC-001, ¶ 11: Trevizo used Allen to ground de novo review of privilege and waiver questions as issues of law (and the trial court’s construction of privilege rules).
  • Pacheco v. Hudson, 2018-NMSC-022, ¶ 24: Cited for the proposition that whether specific communications are privileged is a mixed question of fact and law with de novo review.

3) Statutory/rule construction methodology

  • State v. Strauch, 2015-NMSC-009, ¶¶ 13-14: Provided the interpretive framework emphasizing legislative intent, context, and avoiding absurd or unjust results—central to rejecting the State’s “too broad” reading of the reporting exception.
  • Kipnis v. Jusbasche, 2017-NMSC-006, ¶¶ 10-11: Extended the same interpretive tools to court rules, supporting the Court’s harmonized reading of Section 32A-4-3(A) and Rule 11-504(D)(4).

4) Mandatory reporting and the scope of resulting disclosure

  • State v. Clark, 2013-Ohio-4731, ¶ 85, 999 N.E.2d 592 (O'Connor, C.J., dissenting), rev'd, 576 U.S. 237 (2015): Quoted (via Strauch) for the idea that reporting statutes often require “minimal” disclosure—supporting Trevizo’s conclusion that mandatory reporting triggers limited, not expansive, loss of confidentiality.
  • People v. Covington, 19 P.3d 15, 22 (Colo. 2001) (en banc): Served as persuasive authority for the distinction between (a) unprivileged information necessary to satisfy the mandatory report and (b) continued privilege for broader patient statements made for treatment.

5) Waiver doctrine: third-party presence, voluntariness, and capacity

  • State v. Lucero, 2023-NMCA-035, ¶¶ 24-30: The Court treated Lucero as the closest New Mexico authority on whether a third party overhearing medical communications defeats confidentiality. Trevizo adopted Lucero’s patient-autonomy lens and its insistence that waiver requires conduct reflecting voluntary consent or acquiescence, not mere third-party presence.
  • In re Termination of Parental Rights of Sherry C. & John M., 1991-NMCA-137, ¶¶ 26-28: Used to highlight an additional foundational element implied by “voluntariness”: the patient must have capacity to waive. Trevizo brought that capacity consideration to the foreground and made it an explicit factor in its waiver test.

6) Jurisdiction and issues not reached

  • State v. Smallwood, 2007-NMSC-005, ¶¶ 6, 10-11: Cited to support the Court’s jurisdiction to hear an interlocutory appeal where the defendant could face life imprisonment.
  • Miranda v. Arizona, 384 U.S. 436 (1966): Although the district court found a Miranda violation, the Supreme Court did not reach it because privilege suppression was dispositive.

B. Legal Reasoning

1) Harmonizing mandatory reporting with privilege (Rule 11-504(D)(4) + Section 32A-4-3(A))

The State advanced a categorical theory: because physicians are mandated reporters under Section 32A-4-3(A), and Rule 11-504(D)(4) removes privilege for material “required by law to report,” the privilege never attached in this scenario.

The Court rejected that reading as overbroad and instead construed the statute and rule “together so that they operate harmoniously.” It made two key moves:

  1. Define the unit of required disclosure narrowly. The statute requires reporting “the matter” of knowledge or reasonable suspicion of child abuse or neglect; therefore, the rule’s exception applies only to “material” concerning that specific reportable matter.
  2. Separate the report from subsequent investigative leverage. The report triggers law enforcement’s obligation to investigate (Section 32A-4-3(C)). Once the report is made, the mandated reporter’s duty ends; the privilege does not evaporate to facilitate law enforcement evidence gathering inside the treatment relationship.

This approach prevents the reporting regime from becoming an end-run around confidentiality in emergent care—particularly where treatment settings are vulnerable to coercion and patients may be medically compromised.

2) New Mexico’s waiver-by-third-party-presence rule: a three-part test

The Court explicitly rejected the State’s urged per se rule that third-party presence automatically waives the privilege whenever the third party is “not necessary for care or treatment.” Instead, it extracted and systematized waiver principles from Rule 11-511 (waiver requires “voluntary” disclosure or consent), State v. Lucero (voluntary consent or acquiescence), and In re Termination of Parental Rights of Sherry C. & John M. (capacity concerns).

The Court announced that, for a valid waiver based on a third party’s presence, “at least” these requirements must be met:

  1. Actual knowledge of the third party’s presence (when the third party is not essential to care);
  2. Mental and physical capacity to waive the privilege;
  3. Voluntariness under the totality of the circumstances.

3) Application to the record: incapacity and coercive circumstances

Although the defendant knew police and her mother were present, the Court found the remaining factors decisive:

  • Capacity: The Court found “unequivocally” that the defendant lacked capacity due to excruciating pain, administration of multiple medications including morphine (dose unknown), ongoing severe bleeding, the physical and psychological shock of childbirth, and the doctor’s recognition that the defendant could die from postpartum hemorrhage. Notably, the Court treated the presence of morphine in the infant’s heart blood as corroboration that morphine had meaningful physiological effect in the medical episode.
  • Voluntariness: The Court emphasized the “ambush” nature of the encounter: the physician chose not to speak to the patient about the crisis until police were present “as witnesses,” then entered with armed officers who blocked the doorway, and immediately confronted the patient with “We discovered a dead baby in the bathroom,” without giving any opportunity to exclude nonessential third parties.

Under these circumstances, any purported waiver could not be considered a free and deliberate relinquishment of confidentiality.

C. Impact

1) A clearer, more protective waiver framework in medical settings

Trevizo creates an operational test that trial courts must apply when the State claims a patient waived privilege because police or others overheard medical communications. The emphasis on capacity and totality-of-circumstances voluntariness is likely to be especially important in emergency departments, ambulances, and other high-acuity settings where pain, medication, hemorrhage, shock, or fear may undermine autonomous choice.

2) Limits on using mandatory reporting as an evidentiary pipeline

By construing Rule 11-504(D)(4) narrowly, the Court reduces the risk that mandated reporting statutes become a generalized exception swallowing confidential treatment communications. Hospitals and clinicians may report suspected abuse/neglect, but the State cannot treat that duty as authorization to convert subsequent bedside questioning into unprivileged investigative interrogation.

3) Likely downstream litigation and practice adjustments

  • Suppression motions: Defendants will likely cite Trevizo to challenge admission of statements made during treatment in the presence of police, security, or other third parties, especially where medication or medical distress bears on capacity.
  • Hospital protocols: Institutions may revisit practices around police entry into treatment spaces, documentation of disclosures, and ensuring patients can exercise control over who is present during sensitive communications when medically feasible.
  • Prosecution strategy: The State may be pushed toward evidence independent of privileged treatment communications and toward clearer separation between mandated reporting and investigative interviewing.

4. Complex Concepts Simplified

  • Physician-patient privilege (Rule 11-504): A rule that lets a patient keep private what they tell (and sometimes what is communicated with) their medical provider when it is for diagnosis or treatment, so people can seek care and speak candidly.
  • Confidential communication (Rule 11-504(A)(5)): A communication made privately and not intended to be shared beyond those helping with the medical purpose.
  • Mandatory reporting (Section 32A-4-3(A)): A legal duty requiring certain professionals (including physicians) to immediately report suspected child abuse or neglect to authorities.
  • Exception for required reports (Rule 11-504(D)(4)): The privilege does not cover the limited information the doctor is legally required to report—but Trevizo clarifies that the exception is not limitless; it extends only to the specific reportable “matter.”
  • Waiver (Rule 11-511): You can lose privilege if you voluntarily disclose or agree to disclose a significant part of the privileged communication. Trevizo clarifies that “voluntary” includes having capacity and being free from coercive circumstances.
  • Capacity: The ability—mentally and physically—to make an informed, autonomous choice. Severe pain, shock, blood loss, or sedating medication can undermine it.
  • Totality of the circumstances: Courts do not look at one fact (like whether police were present); they evaluate all surrounding conditions to decide whether a choice was genuinely voluntary.

5. Conclusion

State v. Trevizo establishes two significant clarifications in New Mexico evidence law: (1) the mandatory-reporting exception in Rule 11-504(D)(4) is narrow and limited to what the clinician is required to report under Section 32A-4-3(A), not a wholesale elimination of confidentiality; and (2) waiver of the physician-patient privilege based on third-party presence requires actual knowledge, capacity, and voluntary consent under the totality of the circumstances.

By centering patient autonomy and the realities of emergency medical care, Trevizo raises the evidentiary bar for the State to use bedside statements obtained in the shadow of law enforcement presence and acute medical vulnerability, and it reinforces the privilege’s role in preserving access to candid, lifesaving treatment.
