Spoliation of Surveillance Video: Adverse Inference (Not Liability Preclusion) When Negligent Loss Causes Limited Prejudice

1. Introduction

Alvarez v 100-10 67th Rd. Condominium (2026 NY Slip Op 05261) addresses the proper remedy for spoliation of building surveillance video in a premises-liability slip-and-fall case. The plaintiff, a resident, alleged she slipped on water at the bottom of a stairwell between the fifth and sixth floors on September 4, 2020, and claimed the defendants (the condominium and related parties) were negligent in failing to repair a leaking, defective, and dangerous roof and/or skylight.

The central factual disputes were (i) whether the water was caused by a recurring leak or by an emergent broken skylight, and (ii) whether defendants had actual or constructive notice of the condition. The building had stairwell surveillance cameras that retained footage for three weeks before automatic overwrite. Less than two weeks after the incident, plaintiff’s counsel served a written preservation notice seeking preservation of any video and incident-related materials.

During discovery, defendants produced only a 1 minute 7 second cell-phone recording made by the superintendent from the surveillance system on the day of the incident, depicting moments after the fall—without showing the fall or the period before it. The broader footage was not preserved. The plaintiff moved under CPLR 3126 for spoliation sanctions, ultimately seeking liability-establishing relief or (at least) preclusion of liability defenses.

2. Summary of the Opinion

The Appellate Division, Second Department held that spoliation sanctions were warranted because defendants had a duty to preserve the surveillance footage, were at least negligent in failing to do so, and the missing footage was relevant to plaintiff’s claims. However, the court ruled that the trial court’s sanction—precluding defendants from presenting any testimony, evidence, or defense as to liability at trial—was too severe on these facts. The proper remedy was an adverse inference charge at trial regarding the missing surveillance video.

3. Analysis

3.1 Precedents Cited

Foundational spoliation doctrine and CPLR 3126 authority

Dagro Assoc. II, LLC v Chevron U.S.A., Inc. (206 AD3d 793): Cited for the core proposition that under the common-law doctrine of spoliation, negligent loss or intentional destruction of key evidence may warrant sanctions. In Alvarez, this principle anchors the court’s threshold determination that spoliation is sanctionable even absent proof of intentional destruction.
Yi Jiang Pai v Nelson Senior Hous. Dev. Fund Corp. (232 AD3d 822): Reinforces that spoliation sanctions are available under CPLR 3126 and common-law principles. The citation supports treating missing surveillance footage in routine premises cases as classic spoliation subject to judicial remedy.

The three-part test: duty, culpable state of mind, relevance

LaRose v City of New York (243 AD3d 775) (quoting Washington v Church & Nostrand Apparel Corp., 238 AD3d 1096): Supplies the controlling articulation of what the movant must show: (1) control plus an obligation to preserve at the time of destruction, (2) destruction with a culpable state of mind, and (3) relevance such that a factfinder could conclude the evidence would support the claim or defense. Alvarez applies this framework to surveillance video that was overwritten after a timely preservation notice.

Appellate discretion and proportionality of sanctions

Laporte v New York City Hous. Auth. (242 AD3d 1187) (quoting Hudesman v Dawson Holding Co., 230 AD3d 744): Cited for the proposition that the Supreme Court has broad discretion in selecting an appropriate spoliation sanction. The Second Department then emphasizes that this discretion is not unreviewable.
U.S. Bank N.A. v Sirota (189 AD3d 927): Cited for the appellate court’s authority to substitute its discretion for that of the trial court. This provides the doctrinal basis for the modification from liability preclusion to an adverse inference charge.
Battle v Fulton Park Site 4 Houses, Inc. (245 AD3d 667) (quoting Watson v 518 Pa. Hous. Dev. Fund Corp., 160 AD3d 907): Sets out key calibration factors for sanctions: knowledge and intent, explanation for the loss, and degree of prejudice. Alvarez uses these proportionality considerations to reject a sanction that effectively determines liability.

Comparable outcomes: when adverse inference is the right remedy

Gregorian v New York Life Ins. Co. (211 AD3d 706): Cited both to support that sanctions are warranted where the duty and relevance are shown, and—critically—to support that an adverse inference charge can be the appropriate remedy where preclusion is excessive.
Mendez v La Guacatala, Inc. (95 AD3d 1084): Supports the proposition that spoliation sanctions are appropriate where relevant evidence is not preserved.
Eksarko v Associated Supermarket (155 AD3d 826): Cited as another example where an adverse inference charge is an appropriate sanction for missing video evidence, underscoring the court’s preference for trial-level inference remedies when they adequately address prejudice.

3.2 Legal Reasoning

Duty to preserve was triggered early. The preservation notice was served on September 15, 2020—within the three-week overwrite window described in the record. Because defendants controlled the surveillance system, the notice made it reasonably foreseeable that the footage would be sought in litigation, creating an obligation to preserve it.
Culpable state of mind: negligence sufficed. The Second Department did not require a showing of willful or contumacious conduct. It was enough that defendants were “at least negligent” in failing to preserve the footage once obligated to do so.
Relevance was self-evident given the disputed issues. The missing period (including time before the fall and potentially the fall itself) bore directly on how long water was present, the source of the condition (recurring leak vs emergent skylight break), and therefore notice—core issues in slip-and-fall litigation.
Sanctions must be proportionate to prejudice. Although sanctionable spoliation occurred, the trial court’s preclusion of all liability defenses would have functioned as a near-determinative sanction on contested issues. Applying proportionality factors (intent, explanation, prejudice), the appellate court concluded that an adverse inference at trial adequately remedies the evidentiary gap without over-penalizing defendants beyond the demonstrated prejudice.
The court selected a remedy that restores fairness without deciding the merits. The adverse inference charge permits the jury to infer the missing footage would have been unfavorable to defendants, but still requires plaintiff to prove liability—aligning the sanction with the purpose of spoliation doctrine: leveling the playing field rather than automatically awarding victory.

3.3 Impact

Early preservation letters have real consequences for routine surveillance systems. Building owners and managers using short retention/auto-overwrite systems are on notice that receipt of a preservation demand can obligate immediate action (exporting footage, securing DVR/NVR access, preserving relevant cameras and time windows).
Limits on “case-ending” sanctions for missing video. The decision reinforces that, even where duty/negligence/relevance are established, sweeping preclusion on liability may be deemed excessive absent a stronger showing of willfulness or extreme prejudice. Courts are encouraged to tailor remedies, often favoring adverse inference where it can cure the harm.
Guidance for motion practice under CPLR 3126. Practitioners should frame spoliation motions around the proportionality factors: what the missing footage likely would have shown, why alternative evidence cannot substitute, and how the loss concretely affects proof on key elements (e.g., notice and recurrence).
Trial dynamics: adverse inference as a powerful middle-ground. An adverse inference charge can significantly influence settlement and trial outcomes by allowing jurors to treat the absence of footage as indicative of unfavorable content, while avoiding automatic liability.

4. Complex Concepts Simplified

Spoliation of evidence: The loss, destruction, or significant alteration of evidence that should have been preserved for litigation. It can be intentional or merely negligent.
CPLR 3126: A New York procedural rule allowing courts to sanction parties for failing to disclose or preserve evidence. Sanctions range from mild (costs or adverse inference) to severe (preclusion or striking pleadings).
Adverse inference charge: A jury instruction permitting (but not requiring) jurors to infer that missing evidence would have been unfavorable to the party responsible for its loss.
Preclusion: A sanction barring a party from offering evidence or defenses on particular issues. When applied to “liability,” it can effectively determine the case’s central question.
Actual vs. constructive notice: Actual notice means the defendant truly knew of the hazard; constructive notice means the hazard existed long enough, and was visible and apparent enough, that the defendant should have discovered and corrected it.
Willful/contumacious conduct: Conduct showing intentional, stubborn, or bad-faith disregard of obligations. Some severe sanctions are more likely when this is proven, but Alvarez confirms negligence can still warrant sanctions—just typically less drastic ones.

5. Conclusion

Alvarez v 100-10 67th Rd. Condominium clarifies that while negligent failure to preserve relevant surveillance footage after a timely preservation demand warrants spoliation sanctions, courts must calibrate the remedy to culpability and prejudice. On these facts, the Second Department held that a liability-preclusion sanction was an improvident exercise of discretion and replaced it with an adverse inference charge—preserving the jury’s role in resolving disputed premises-liability issues while addressing the evidentiary imbalance created by the missing video.
