Peterson v. Credit Agricole Am. Servs., Inc.: CPLR 5015(a) Vacatur Unavailable Absent a True Default; Inherent “Substantial Justice” Relief Limited; CPLR 3126 Dismissal Upheld for Willful, Deceptive Discovery Misconduct

Introduction

In Peterson v Credit Agricole Am. Servs., Inc. (2026 NY Slip Op 01078 [2d Dept Feb. 25, 2026]), the Appellate Division, Second Department reversed a Supreme Court order that had vacated an earlier order dismissing the plaintiff’s complaint as a discovery sanction.

The plaintiff, Kelley Peterson, sued multiple Credit Agricole entities and her supervisor, Mickael Abid, alleging hostile work environment and sexual harassment in violation of Executive Law § 296, including allegations that Abid coerced her into a romantic and sexual relationship. The key procedural dispute became whether the plaintiff’s repeated discovery failures—and alleged deception regarding control of documents and accounts—warranted dismissal under CPLR 3126, and whether the plaintiff could later undo that dismissal by moving to vacate under CPLR 5015(a).

The central legal issues were:

  • Whether the dismissal order was “entered on default,” permitting vacatur under CPLR 5015(a)(1).
  • Whether the court could vacate the dismissal order under its inherent authority “in the interest of substantial justice.”
  • Whether dismissal under CPLR 3126 was a proper sanction for the plaintiff’s discovery conduct.

Summary of the Opinion

The Second Department held that the February 1, 2024 dismissal/sanctions order was not entered on default because the plaintiff had submitted opposition and the order reflected that the opposition was considered (see CPLR 2219[a]). Therefore, vacatur under CPLR 5015(a)(1) was unavailable.

The Court further held that vacatur “in the interest of substantial justice” was not warranted because the plaintiff offered no evidence of fraud, mistake, inadvertence, surprise, or excusable neglect—recognized limits on the court’s inherent power to relieve a party from an order.

Finally, the Court indicated there was no basis, even on reargument, to disturb the underlying CPLR 3126 determination. The record supported an inference of willful and contumacious conduct, including selective withholding of documents, false claims of inability to access accounts, revelations produced only via forensic examination, and an unsupported claim that missing diary portions had been stolen. Under those circumstances, dismissal and monetary sanctions were justified.

Analysis

Precedents Cited

Aurora Loan Servs., LLC v Dorfman

The Opinion relies on Aurora Loan Servs., LLC v Dorfman, 170 AD3d 786, 788, for the proposition that courts possess an inherent discretionary power to relieve a party from a judgment or order “for sufficient reason and in the interest of substantial justice.” However, Aurora is used here as a gateway to emphasize that such power is not boundless; it must be tethered to recognized grounds (e.g., mistake or excusable neglect) rather than functioning as a general equitable “do-over.”

Matter of McKenna v County of Nassau, Off. of County Attorney

The core limiting principle comes from Matter of McKenna v County of Nassau, Off. of County Attorney, 61 NY2d 739, 742: a court’s inherent control over its orders and judgments “is not plenary,” and should be used only to relieve a party from orders/judgments taken through “mistake, inadvertence, surprise or excusable neglect” (and, as framed in this Opinion, also fraud). The Second Department deploys McKenna to reject the plaintiff’s attempt to invoke “substantial justice” absent a qualifying explanation.

Gutierrez v Hillside Hotel, LLC

The Court cites Gutierrez v Hillside Hotel, LLC, 234 AD3d 672, 674, alongside McKenna, reinforcing that the “substantial justice” rubric does not expand inherent authority into a free-floating equity power; it remains cabined by traditional vacatur grounds.

Amato v Lord & Taylor, Inc.

Amato v Lord & Taylor, Inc., 10 AD3d 374, 375, is cited for the procedural point that “reargument” is not an independent basis to vacate a prior order absent a showing that the earlier determination should be changed. The Opinion uses Amato to support its conclusion that even if the motion were treated as reargument, there was no basis to undo the CPLR 3126 dismissal.

Lucas v Stam; Morgenstern v Jeffsam Corp.; Duncan v Hebb; Dokaj v Ruxton Tower Ltd. Partnership

These decisions supply the sanction framework under CPLR 3126:

  • Lucas v Stam, 147 AD3d 921, 925: the nature and degree of penalty under CPLR 3126 lies within the Supreme Court’s discretion.
  • Morgenstern v Jeffsam Corp., 78 AD3d 913, 914: sanctions are appropriate where a party frustrates disclosure; willfulness/contumacy can be inferred from prolonged noncompliance and lack of adequate excuse.
  • Duncan v Hebb, 47 AD3d 871, 871: appellate courts will not disturb such sanctions absent an improvident exercise of discretion.
  • Dokaj v Ruxton Tower Ltd. Partnership, 91 AD3d 812, 814: striking a pleading may be warranted when a party’s conduct is willful and contumacious.

In Peterson, these precedents collectively support the Court’s conclusion that dismissal was within the permissible sanction range, particularly given findings of selective production, misrepresentations about access/control, and noncompliance requiring forensic measures.

Legal Reasoning

1) The dismissal order was not “entered on default” (CPLR 5015(a)(1) unavailable)

The Second Department drew a bright procedural line: when a party submits opposition papers and the order indicates those papers were considered (see CPLR 2219[a]), the resulting order is not “on default.” As a result, CPLR 5015(a)(1)—the default-vacatur mechanism—does not apply. This prevents litigants from reframing an adverse, merits-based (or discretion-based) motion determination as a default simply because the order was unfavorable or issued “without comment.”

2) “Substantial justice” does not confer plenary vacatur power

The Opinion acknowledges that New York courts possess inherent authority to vacate orders in the interest of substantial justice, but emphasizes that this authority is exceptional and bounded. Citing Aurora Loan Servs., LLC v Dorfman and Matter of McKenna v County of Nassau, Off. of County Attorney, the Court held that inherent relief should be reserved for circumstances akin to fraud, mistake, inadvertence, surprise, or excusable neglect. The plaintiff’s motion failed because it offered no evidentiary basis fitting those categories.

3) Dismissal under CPLR 3126 was justified on this record

Applying the CPLR 3126 standard, the Court held the plaintiff’s conduct could be deemed willful and contumacious, inferred from:

  • Extended failure to comply with discovery demands.
  • Inadequate excuses (counsel’s “slipped through the cracks”).
  • A late but deficient response.
  • The need for a CPLR 3124 motion to compel and a forensic examination request.
  • Selective withholding of hundreds of documents relevant to whether the relationship was consensual, while denying access/control.
  • Revelations during a court-ordered forensic examination that documents/accounts were in the plaintiff’s control (including a Dropbox created under her personal email).
  • Partial diary production followed by a claim the remainder was “stolen,” after repeated requests for full production.

The Court thus endorsed dismissal and monetary sanctions as proportionate to misconduct that did not merely delay discovery, but undermined the integrity of the disclosure process through apparent deception—especially where the withheld material went to a “key issue” in dispute.

Impact

Procedural impact: limiting post-order “second bites”

The decision reinforces that CPLR 5015(a)(1) is not a vehicle to revisit adverse motion outcomes where opposition was filed and considered. Practically, parties seeking to challenge a CPLR 3126 dismissal must pursue appropriate routes (timely reargument/renewal where applicable, or appeal), rather than relabeling the decision as a default to invoke CPLR 5015(a)(1).

Sanctions impact: heightened risk where noncompliance includes deception

Peterson underscores that CPLR 3126 dismissal is especially supportable where noncompliance is intertwined with misrepresentations about possession, custody, control, or access to electronically stored information (and other evidence). The Opinion signals that courts may treat forensic examinations and subsequent revelations as powerful proof of willfulness/contumacy, making dismissal more likely to withstand appellate review.

Substantive-case context: discrimination claims do not insulate discovery misconduct

Although the underlying claims involve sexual harassment and hostile work environment under Executive Law § 296, the Court’s analysis emphasizes process integrity: serious substantive allegations do not prevent dismissal where the plaintiff’s discovery behavior is found willful, obstructive, and dishonest.

Complex Concepts Simplified

  • CPLR 3124 (motion to compel): a request asking the court to order the other side to provide overdue discovery.
  • CPLR 3126 (sanctions for discovery misconduct): allows the court to impose penalties—up to and including dismissal/striking pleadings—when a party refuses to obey discovery obligations or court orders.
  • “Willful and contumacious”: conduct showing intentional, stubborn noncompliance (often inferred from repeated failures, inadequate excuses, and disregard of court directives).
  • CPLR 5015(a)(1) (vacatur for default): permits vacating an order entered because a party failed to appear or respond; it does not apply when opposition was filed and considered.
  • “In the interest of substantial justice” (inherent power): an exceptional court power to correct certain unjust outcomes, but limited to recognized grounds like mistake or excusable neglect; it is not a general power to redo decisions.
  • CPLR 2219(a): requires that an order deciding a motion reflect that the court considered the papers (supporting the conclusion that the order was not entered on default).
  • Forensic examination (in discovery): technical inspection of devices/accounts to identify relevant data and evaluate whether information was deleted or withheld.

Conclusion

Peterson v Credit Agricole Am. Servs., Inc. delivers three key takeaways. First, an order deciding a motion after reviewing opposition is not “on default,” and CPLR 5015(a)(1) cannot be used to vacate it. Second, the court’s inherent “substantial justice” authority is tightly constrained and requires proof of traditional vacatur grounds (e.g., mistake or excusable neglect). Third, CPLR 3126 dismissal will be sustained where prolonged noncompliance is coupled with selective production and apparent deception—particularly when the missing evidence bears on a central disputed issue.
