The Turner Rule: Tenth Circuit Bars Post-Discovery Pivot—Plaintiffs Must Amend Pleadings to Rely on New Factual Theories

1. Introduction

Shyers v. Metropolitan Property & Casualty Insurance Co., No. 24-5036 (10th Cir. July 25, 2025) arose from a commercial-property fire, an insurance dispute, and ultimately a fatal procedural misstep. The deceased insured, Michael Turner (substituted on appeal by his estate administrator, P. J. Shyers), alleged that MetLife and its local agent, Farmer Brown, misrepresented the scope of “replacement-cost” coverage and acted in bad faith.

The crux of the appeal was not the fire, but pleading practice. Turner attempted to oppose summary judgment with factual theories—e.g., seasonal business-loss calculations, unlimited replacement coverage, constructive fraud—that never appeared in his operative complaint. The Tenth Circuit seized the opportunity to crystallise a principle that had been implicit in prior authority:

Plaintiffs cannot defeat summary judgment by springing new factual theories drawn from discovery; they must either plead them or formally amend under Rule 15.

This commentary unpacks that new “Turner Rule”, the court’s reasoning, and its implications.

2. Summary of the Judgment

Jurisdiction preserved: Despite Turner’s death before the Notice of Appeal, Rule 3(c)(7) and Rule 43(a) allowed substitution; the Court rejected MetLife’s jurisdictional attack.
Reformation claim rejected: Turner lacked clear and convincing evidence of a prior meeting of the minds on unlimited replacement coverage. His sole evidence—a self-serving declaration—was inadmissible hearsay after his death.
Contract-breach & bad-faith claims rejected: All were parasitic on the failed reformation theory or on new factual contentions (mis-calculated seasonal losses, “other coverages”) that had never been pled.
Negligence/fraud against agent rejected: The operative pleading stated “negligence”; the late pivot to fraud at summary-judgment stage was impermissible.
Leave to amend properly denied: Years of delay, closed discovery, and perceived “salvage” motives justified refusal under Rule 15(a).

3. Detailed Analysis

3.1 Precedents Cited and Their Influence

Celotex Corp. v. Catrett, 477 U.S. 317 (1986) – bedrock summary-judgment standard: burden shifts to non-movant to show triable facts.
Whitaker v. Milwaukee Cnty., 772 F.3d 802 (7th Cir. 2014) – forbids “radical” factual shifts at summary judgment; adopted by analogy.
Estate of Slade, 952 F.2d 357 (10th Cir. 1991) – substitution of deceased party; used to defeat MetLife’s jurisdictional argument.
Oklahoma Oncology & Hematology v. U.S. Oncology, 160 P.3d 936 (Okla. 2007) & Gentry v. Am. Motorist Ins., 867 P.2d 468 (Okla. 1994) – standards for contract reformation; Turner's evidence fell short.
Minter v. Prime Equip. Co., 451 F.3d 1196 (10th Cir. 2006) – factors governing late amendments; guided the denial of leave to amend.
Argo v. Blue Cross & Blue Shield, 452 F.3d 1193 (10th Cir. 2006) – admissibility at trial required for summary-judgment evidence; fatal to Turner’s declaration.

3.2 The Court’s Legal Reasoning

Pleading/Due-Process Nexus. Rule 8 requires “fair notice”. When discovery unearths new facts, Rule 15—not Rule 56—is the vehicle to bring them into play. Allowing new theories at summary-judgment stage ambushes defendants and erodes judicial efficiency.
Evidentiary Gatekeeping at Summary Judgment. Because Turner died, his declaration became inadmissible hearsay. Without admissible proof of pre-loss representations, the reformation claim collapsed under Oklahoma’s clear-and-convincing standard.
Cascade Effect. Once reformation failed, the expanded replacement-cost and derivative bad-faith counts necessarily failed. Remaining breach-of-contract/bad-faith theories lacked pleaded factual support and could not be raised belatedly.
Leave to Amend—Discretionary and Contextual. Two years of litigation, closed discovery, and plaintiff’s “salvage” motive satisfied the Minter factors for denying amendment.

3.3 Impact of the Decision (“The Turner Rule”)

Litigation Strategy: Plaintiffs in the Tenth Circuit must now treat discovery as a prompt to amend, not a license to pivot at summary judgment. Early, iterative pleading is essential.
Defense Playbook: Defendants can confidently move to strike or disregard unpleaded factual theories advanced in Rule 56 papers, invoking Turner.
Insurance Litigation: Insureds challenging policy limits (reformation) will face higher evidentiary hurdles; self-serving affidavits are inadequate where clear-and-convincing proof is required.
Hearsay Awareness: When a key witness is elderly or ill, counsel must preserve testimony (e.g., depositions) early; reliance on later declarations is risky.
Rule 3 & 43 Guidance: Turner clarifies that omission of a decedent’s personal representative in the notice of appeal does not defeat jurisdiction if intent to appeal is clear.

4. Complex Concepts Simplified

Summary Judgment (Rule 56): A mechanism to end cases without trial when no material fact is disputed and movant is entitled to judgment as a matter of law.
Pleading vs. Proof: “Pleading” invokes Rule 8’s notice standard; “proof” arises later under Rules 56/50. Turner conflated the two, pleading sparsely then trying to prove extensively.
Contract Reformation: Equitable remedy rewriting a document to reflect the parties’ true agreement, available only upon clear and convincing evidence of mutual mistake or fraud.
Clear and Convincing Evidence: Higher than “preponderance”, lower than “beyond reasonable doubt”; evidence must make the fact “highly probable”.
Hearsay vs. Former Testimony Exception (Rule 804): Out-of-court statements offered for truth are inadmissible unless an exception applies. A mere declaration is not “former testimony” because there was no opportunity for cross-examination.
Rule 15 Amendment: Pleadings may be amended “freely” early, but courts weigh delay, prejudice, bad faith, and futility when litigation is advanced.

5. Conclusion

The Tenth Circuit’s decision in Shyers v. MetLife transcends the immediate insurance dispute. It crystallises a procedural rule of broad application:

A plaintiff who uncovers new facts in discovery must amend the complaint; reliance on those facts for the first time at summary judgment is barred.

This “Turner Rule” promotes fair notice, curbs gamesmanship, and streamlines litigation. Coupled with the court’s evidentiary vigilance and pragmatic stance on appellate substitution, the judgment furnishes a road-map for both plaintiffs and defendants navigating complex civil cases in the Tenth Circuit and beyond.
