Late “Supplemental” Expert Disclosure Is Precludable Absent Good Cause—Especially When It Adds a New Specialty After the Note of Issue

3.1 Precedents Cited

A. Expert disclosure timing, supplementation, and preclusion (CPLR 3101[d])

• Freeman v State of New York: Quoted for the proposition that although CPLR 3101(d)(1)(i) does not specify a disclosure deadline, trial courts may set one and impose sanctions for noncompliance. In Schultz, this supplied the doctrinal basis for enforcing scheduling orders and rejecting late expert additions.
• Bohlke v General Elec. Co.: Cited with Freeman to reinforce trial court discretion to manage expert deadlines under general supervisory authority.
• Douglass v St. Joseph's Hosp.: Central to the court’s analysis; it states preclusion is within discretion where the noncomplying party fails to show good cause for delay and/or that disclosure was not intentionally withheld. The Third Department used Douglass to frame “good cause” as the critical missing element in plaintiff’s request.
• Lasher v Albany Mem. Hosp.: Used twice—first for the standard that only a “clear abuse” of discretion warrants appellate intervention, and again to support denial of late expert disclosure absent good cause.
• Maggio v Doughtery: Reinforces deference to the trial court’s discretion on expert preclusion and scheduling enforcement.
• Colucci v Stuyvesant Plaza, Inc. (and “lv denied” reference) and Tienken v Benedictine Hosp.: Both support the point that lengthy discovery periods and repeated extensions make unexplained late disclosure harder to justify; they underscore that “protracted” timelines do not excuse noncompliance.
• Meyer v Zeichner: Cited as additional support for denying late expert disclosure where good cause is absent.

B. Summary judgment burdens in medical malpractice

• Henderson v Takemoto: Cited for the defendant’s prima facie burden on summary judgment—proof (often via records and expert affidavits) that defendant complied with accepted standards of care or did not cause injury.
• Sovocool v Cortland Regional Med. Ctr.: Cited for both stages of the burden-shifting framework: defendant’s prima facie showing and plaintiff’s obligation to come forward with evidence of deviation and proximate cause.
• Schwenzfeier v St. Peter's Health Partners: Reinforces plaintiff’s responsive burden to raise a triable issue on both departure and causation.
• Snyder v Simon, Hoffman v Pelletier, and Rossi v Arnot Ogden Med. Ctr. (and “lv denied” reference): These cases support the principle applied here—that conclusory or off-point expert proof that does not specify the standard of care, the deviation, and causation fails to defeat summary judgment.

C. Preservation of issues for appellate review

• Carroll v Rondout Yacht Basin, Inc. (and “lv dismissed” reference) and Kumar v Franco: Cited for the rule that arguments not raised before Supreme Court are unpreserved on appeal. The Third Department invoked these cases to reject plaintiff’s argument regarding defendant allegedly naming a nonparty.

D. Loss of consortium in wrongful death actions

• Liff v Schildkrout and Sand v Chapin: Cited for the rule that loss of consortium is not recoverable as part of a wrongful death action in New York; therefore, plaintiff’s derivative consortium claim was properly dismissed.

E. Expert competency outside specialty

• Samer v Desai and Postlethwaite v United Health Servs. Hosps.: Used in a footnote to emphasize that if an expert opines outside their specialty, they must explain their familiarity with the relevant area; this underlines why plaintiff’s pathologist affidavit could not silently bridge into endoscopy/fall-risk standards.

3.2 Legal Reasoning

A. “Supplementation” is not a magic word—courts look at substance

Plaintiff argued he preserved the ability to supplement by inserting generic language reserving the right to seek permission to amend or supplement expert disclosure. The Third Department rejected that framing. The court treated the request as what it functionally was: not a clarification of the existing forensic pathologist’s opinions, but the late introduction of a second expert—“a surgeon”—with opinions on surgery and postoperative supervision, i.e., a “wholly unrelated field” to the pathologist’s cause-of-death focus.

That characterization matters because adding a new specialty changes the litigation landscape: it expands theories of departure, may require additional depositions, and alters motion practice fairness—precisely the types of prejudice and disruption that scheduling orders are meant to prevent.

B. Timing and the “good cause” gap

The court emphasized three timing facts: (1) plaintiff disclosed the second expert’s identity and opinion only in response to defendant’s summary judgment motion; (2) the surgeon’s affidavit was dated seven months after the note of issue; and (3) plaintiff offered no excuse—“much less good cause”—despite lengthy discovery and multiple extensions.

In the Third Department’s framing (consistent with Douglass v St. Joseph's Hosp. and Lasher v Albany Mem. Hosp.), the absence of a concrete explanation is dispositive: without good cause, the trial court may preclude the expert and appellate courts will not interfere absent clear abuse of discretion.

C. Summary judgment: defendant’s prima facie showing versus plaintiff’s responsive proof

On the merits, the court applied the standard burden-shifting approach. Defendant met its initial burden through medical records and three expert affidavits (gastroenterologist, oncologist/hematologist, pathologist), each opining that care conformed to accepted standards—specifically, that the upper endoscopy was necessary and appropriately performed, that fall risk was appropriately assessed, and that the autopsy met proper standards and regulations.

Plaintiff’s problem was evidentiary: once the late surgeon was excluded, the only admissible expert proof was the forensic pathologist, whose affidavit did not:

• identify or define the applicable standard of care for endoscopy or fall-risk assessment,
• explain how defendant deviated from accepted practice in treating the decedent, or
• address causation—how any alleged departure proximately caused the injuries or wrongful death.

Under the cited Third Department authorities (Snyder v Simon, Hoffman v Pelletier, Rossi v Arnot Ogden Med. Ctr.), that omission is fatal: expert proof must connect the dots—standard, departure, and causation—to create a triable issue.

D. Preservation and wrongful-death damages boundaries

The court also resolved two “cleanup” points that frequently recur in appeals: it deemed plaintiff’s “nonparty naming” argument unpreserved (Carroll v Rondout Yacht Basin, Inc.; Kumar v Franco), and it reaffirmed that loss of consortium is not a cognizable component of wrongful death damages (Liff v Schildkrout; Sand v Chapin).

3.3 Impact

Schultz consolidates and sharpens a practical rule in New York malpractice litigation: a party cannot wait until summary judgment (or after filing the note of issue) to pivot into a new liability theory by labeling a new expert as a “supplement.” Trial courts may treat such attempts as untimely new disclosures, and—absent a specific, supported showing of good cause—preclude them.

The decision also illustrates a recurring summary judgment consequence: even where a plaintiff has an expert, the expert must be fit-for-purpose. A forensic pathologist’s views about autopsy issues will not, without articulated familiarity and specific standards analysis, substitute for specialty-specific proof on endoscopy practice, inpatient fall-risk precautions, postoperative monitoring, or medical causation.

Finally, the reaffirmation of Liff v Schildkrout in this posture serves as a reminder to plead and damages-strategize correctly: wrongful death claims do not carry a free-standing consortium component in New York.
