Background

Cheri Sheree Moore gave birth at Mercy Medical Center in May 2015 following a prolonged labor. Her newborn son, P.C.M., was delivered by emergency cesarean section on May 29, 2015, and required intubation for respiratory distress. He was subsequently diagnosed with stridor and vocal-cord paralysis and later developed seizures, temporary paralysis, speech delays, and other serious conditions. Moore filed a medical-malpractice complaint against Mercy Medical Center and two treating physicians, Dr. Godwin Meniru and Dr. Albert Domingo, alleging deviations from the accepted standard of care during her labor and delivery.

Moore’s expert, Dr. Martin Gubernick, issued a November 2022 report concluding that the standard of care required a C-section by 7:00 p.m. on May 28, 2015—a time when Dr. Meniru was off duty and Dr. Domingo was managing Moore’s care. When Dr. Meniru moved for summary judgment on the ground that the alleged malpractice occurred during his absence, Moore filed a new affidavit from Dr. Gubernick in April 2023. That affidavit incorporated the November 2022 report by reference but added a previously unasserted opinion: that Dr. Meniru independently breached the standard of care on the morning of May 29 by failing to order a C-section within 30 minutes of being notified of fetal distress upon resuming care.

Dr. Meniru moved to strike the April 2023 affidavit as a sham affidavit—arguing it was manufactured solely to defeat summary judgment and directly contradicted Dr. Gubernick’s prior report. The trial court agreed, struck the affidavit, and granted summary judgment for Dr. Meniru. The Fifth District Court of Appeals affirmed, and the Supreme Court of Ohio accepted the case on two propositions of law concerning the scope and application of the sham-affidavit rule.

The Court’s Holding

The Supreme Court of Ohio, in a 5-2 decision authored by Justice Hawkins, affirmed. The court held that when an expert incorporates a Civ.R. 26(B)(7) expert report by reference into a properly framed affidavit under Civ.R. 56(E), the expert adopts the contents of that report as part of the sworn affidavit for summary-judgment purposes. Once the report is thus brought before the court as sworn material, the court may assess the consistency of the opinions in the report and the affidavit under the sham-affidavit rule—even though the original report was unsworn.

The court rejected Moore’s argument that the sham-affidavit rule is limited to contradictions between sworn statements, such as a prior deposition and a later affidavit. Because Dr. Gubernick’s report was incorporated by reference into his affidavit and both documents were properly before the trial court, the report effectively became part of the sworn record. The court further found that the two opinions were clearly contradictory: the original report fixed the standard-of-care deadline at 7:00 p.m. on May 28 (when Dr. Meniru was off duty), while the affidavit extended that deadline to the morning of May 29 (when Dr. Meniru had resumed care).

The court also rejected Moore’s explanation that the contradiction was justified by new information from Dr. Meniru’s March 2023 deposition. Dr. Meniru’s operative report—available before Dr. Gubernick wrote his November 2022 report—already disclosed that he had been paged around 7:30 a.m. on May 29 and informed of fetal heart decelerations. Because the underlying facts were knowable before the original report, Moore provided no sufficient explanation for the changed opinion, and the trial court acted within its discretion in striking the affidavit.

Key Takeaways

  • When an expert incorporates a Civ.R. 26(B)(7) report into a Civ.R. 56(E)-compliant affidavit, the report’s contents are treated as sworn testimony for summary-judgment purposes, making them subject to the sham-affidavit rule.
  • The sham-affidavit rule is not limited to contradictions between prior sworn depositions and later affidavits; it applies whenever a sworn affidavit contradicts a prior statement properly before the court as part of the sworn record.
  • A party seeking to explain away a contradiction must demonstrate that the changed opinion is based on genuinely new information not previously available; if the underlying facts were accessible before the original report, the explanation is insufficient.
  • A trial court acts within its discretion in striking a contradictory expert affidavit rather than merely treating the inconsistency as a question of credibility or weight at the summary-judgment stage.

Why It Matters

This decision clarifies and extends Ohio’s sham-affidavit doctrine in a context that frequently arises in medical-malpractice litigation: an expert who issues a disclosure report under Civ.R. 26(B)(7) and later attaches that report to a summary-judgment affidavit cannot use the affidavit to introduce materially contradictory new opinions without adequate justification. Defense counsel can now argue that incorporating an expert report into an affidavit effectively “locks in” the expert’s disclosed opinions, making it harder for plaintiffs to pivot their theory of liability at the summary-judgment stage by exploiting the technical distinction between sworn and unsworn documents.

The two-justice dissent argued that the opinions were not truly contradictory—both physicians could have independently breached the standard of care at different points in time—and cautioned that the sham-affidavit rule should be applied sparingly and only when a clear contradiction exists, with all inferences drawn in favor of the nonmoving party. The dissent’s reasoning underscores that the boundaries of the rule remain contested, and litigants in Ohio should expect continued scrutiny over when an expert’s later affidavit genuinely supplements versus impermissibly contradicts a prior disclosure report.
