Renewed Discovery of Electronic Medical Record Audit Trails After New Deposition Evidence (Harms v. Lewis)

1. Introduction

Harms v Lewis (2026 NY Slip Op 02550 [4th Dept Apr. 24, 2026]) arises from a medical malpractice and wrongful death action brought by Florence Louise Harms, individually and as executor of the estate of Robert L. Harms (plaintiff-respondent), against, among others, TLC Health Network and Lake Shore Health Care Center (defendants-appellants).

The appeal concerns a recurring discovery dispute over disclosure of electronic medical record (EMR) audit trails—metadata that can show who accessed a chart, when entries were created or modified, and related activity. The key issues were:

  • Whether the trial court properly compelled additional audit-trail-related discovery after a prior appellate decision had affirmed denial of similar relief.
  • Whether the law of the case doctrine barred the renewed discovery motion.
  • Whether new deposition testimony undermining earlier affidavits justified expanded discovery into audit trails and retention practices.

2. Summary of the Opinion

The Fourth Department unanimously affirmed Supreme Court’s order compelling defendants to comply with discovery demands related to EMR audit trails. The court held that:

  • Trial courts have broad discretion over disclosure, and there was no abuse of discretion in granting the renewed (second) motion.
  • The order did not conflict with the court’s earlier ruling because the second motion relied on new evidence developed after the first motion—particularly deposition testimony contradicting prior affidavits about audit-trail availability and knowledge of retention policies.
  • The law of the case doctrine did not bind Supreme Court because intervening depositions introduced additional evidence and issues; in any event, law of the case does not bind the Appellate Division’s review.

3. Analysis

3.1. Precedents Cited

A. The case’s procedural anchor: the prior Harms audit-trail appeal

The court framed the dispute as a sequel to Harms v TLC Health Network (215 AD3d 1295 [4th Dept 2023]). In that earlier appeal, the Fourth Department had affirmed denial of plaintiff’s motion to strike or compel, emphasizing two points that became pivotal here:

  • Plaintiff had not shown “willful, contumacious, or . . . bad faith” noncompliance, and
  • The record contained “no showing, beyond mere conjecture” that audit trails would yield relevant information unobtainable from already-produced records, and defendants provided “reasonable explanations” for why some information was no longer available.

In Harms v Lewis, the Fourth Department treated Harms (2023) not as a categorical bar to audit-trail discovery, but as a record-dependent ruling. Because the evidentiary record materially changed after depositions, the earlier affirmance did not control the renewed request.

B. Broad discretion over discovery

The court reiterated that supervision of disclosure is committed to trial-court discretion and is rarely disturbed absent clear abuse, relying on:

  • Prattico v City of Rochester (197 AD3d 882 [4th Dept 2021])
  • Castro v Admar Supply Co., Inc. [appeal No. 2] (159 AD3d 1616 [4th Dept 2018])
  • Allen v Wal-Mart Stores, Inc. (121 AD3d 1512 [4th Dept 2014])

These cases supplied the standard of appellate review: unless Supreme Court’s disclosure management was clearly improvident, the order stands.

C. Scope of disclosure under CPLR 3101(a)

The opinion quoted CPLR 3101(a): “There shall be full disclosure of all matter material and necessary in the prosecution or defense of an action,” and cited Crysler v Erk [appeal No. 2] (227 AD3d 1410 [4th Dept 2024]) to reinforce that New York’s disclosure standard is broad. This statutory premise supported compelling not only the audit trails themselves (if they exist), but also discovery reasonably calculated to determine existence, retention, and accessibility (e.g., policies, knowledgeable witnesses, and production methods).

D. When audit trails are discoverable

The Fourth Department drew a clear doctrinal line for EMR metadata discovery: audit trails are subject to discovery where a plaintiff raises legitimate questions whether medical records were withheld or altered, citing:

  • Wright v Stephens (239 AD3d 1271 [4th Dept 2025])
  • Vargas v Lee (170 AD3d 1073 [2d Dept 2019])

Harms v Lewis applied that principle to the post-deposition record: deposition testimony contradicted earlier representations about audit-trail nonexistence and revealed uncertainty about retention practices, supporting a non-speculative basis to suspect additional relevant audit-trail information may exist and may not have been produced.

E. Law of the case limits when the record changes

Defendants argued the prior appellate decision bound Supreme Court under law of the case. The Fourth Department rejected that position, relying on:

  • Milligan v Bifulco (153 AD3d 1624 [4th Dept 2017])
  • M & T Bank Corp. v Moody's Invs. Servs., Inc. (191 AD3d 1288 [4th Dept 2021])
  • Ziolkowski v Han-Tek, Inc. (126 AD3d 1431 [4th Dept 2015])

The court’s core point: law of the case does not apply where subsequent discovery “introduced additional evidence and raised further issues.” Depositions taken after the first motion did exactly that.

The opinion further emphasized an important appellate nuance: even if law of the case could be argued at the motion court level, it is “not binding upon this Court’s review,” citing:

  • Ziolkowski v Han-Tek, Inc. (126 AD3d 1431 [4th Dept 2015])
  • Martin v City of Cohoes (37 NY2d 162 [1975], rearg denied 37 NY2d 817 [1975])
  • Micro-Link, LLC v Town of Amherst (155 AD3d 1638 [4th Dept 2017])

3.2. Legal Reasoning

  1. Discovery discretion and CPLR breadth. Starting from CPLR 3101(a)’s “material and necessary” standard, the court applied the deferential abuse-of-discretion review described in Prattico, Castro, and Allen.
  2. Audit-trail discovery requires more than conjecture—but may be justified by later-developed evidence. The court distinguished the earlier denial (based on lack of non-speculative support and “reasonable explanations” of unavailability) from the present record. Deposition testimony supplied the missing predicate: contradictions to earlier affidavits and uncertainty about retention practices supported “legitimate questions” under Wright v Stephens and Vargas v Lee.
  3. No impermissible conflict with the prior appellate determination. The prior decision was explicitly grounded in the then-existing record. Because the renewed motion was supported by new deposition evidence suggesting availability and potential withholding, the trial court’s order was consistent with, rather than contrary to, the earlier ruling.
  4. Law of the case does not freeze discovery when the facts evolve. The court reasoned that intervening depositions changed the evidentiary landscape, precluding law-of-the-case application under Milligan v Bifulco and related cases. It also underscored that appellate review is not constrained by law of the case in the same way the motion court might be.

3.3. Impact

Harms v Lewis reinforces and operationalizes two practical rules for New York discovery disputes involving EMR audit trails:

  • Record-dependent entitlement: audit trails are not automatically discoverable, but plaintiffs can obtain them (and related process/policy discovery) when they develop a concrete basis—such as deposition admissions or contradictions—to question completeness or integrity of produced records.
  • Renewed motion pathway: a prior denial or affirmance does not foreclose later audit-trail discovery if later discovery (especially depositions) materially changes what is known about existence, retention, accessibility, or prior representations. Courts may compel production of knowledgeable witnesses, retention policies, and technical details necessary to locate and produce audit trails.

For healthcare defendants and institutional litigants, the decision heightens the litigation importance of: (i) accurate affidavits about data retention and availability, (ii) producing properly prepared corporate/organizational witnesses, and (iii) being able to explain audit-trail architecture and preservation in a consistent, technically competent manner.

4. Complex Concepts Simplified

  • EMR “audit trails”: computerized logs that can show user access and changes to an electronic chart (e.g., who opened a record, when, and what was edited). They are often stored differently from the “printed” or displayed medical record.
  • “Material and necessary” (CPLR 3101[a]): New York’s broad discovery standard; information is discoverable if it is reasonably related to the claims or defenses, even if it would not itself be admissible at trial.
  • “Willful” or “contumacious” noncompliance: stubborn, intentional failure to comply with discovery obligations—often relevant to harsh sanctions like striking an answer.
  • Law of the case: a doctrine that generally discourages re-litigating issues already decided in the same case; it is weakened or inapplicable when new evidence emerges or when the later motion raises materially different issues.
  • Abuse of discretion (discovery context): the appellate court will not substitute its judgment for the trial court’s unless the order is clearly unreasonable or erroneous.

5. Conclusion

Harms v Lewis stands for a pragmatic, evidence-sensitive rule in EMR metadata disputes: while audit-trail requests cannot rest on conjecture, a plaintiff who later uncovers contradictions or gaps through depositions may renew discovery and obtain audit trails and related foundational discovery (policies, production methods, and knowledgeable witnesses). The decision also underscores that a prior appellate affirmance on a different record does not lock in discovery outcomes under law of the case when subsequent evidence changes the landscape.
