Waiver of Household Vehicle Exclusion: Insurer Must Timely Plead Policy Exclusions as Affirmative Defenses; Mione Did Not “Change” Pennsylvania Law

I. Introduction

In Haley Rodd v. James McCoy; Progressive Specialty Insurance Co., No. 25-1601 (3d Cir. Mar. 3, 2026) (not precedential), the Third Circuit affirmed a series of trial-level rulings that prevented an insurer—Progressive Specialty Insurance Co.—from invoking a Pennsylvania auto policy’s “household vehicle exclusion” to defeat underinsured motorist (“UIM”) coverage.

The dispute arose after Haley Rodd was injured in a 2017 collision while driving her uninsured vehicle. The tortfeasor’s coverage was insufficient, so Rodd sought UIM benefits under her parents’ Progressive policy. Progressive initially denied coverage based on the household vehicle exclusion, then reversed course after Gallagher v. GEICO Indemnity Co., 201 A.3d 131 (Pa. 2019), and agreed UIM benefits were available. When the parties later litigated the amount of coverage (and Rodd added bad faith), Progressive tried—years into the case and again at trial—to reintroduce the household vehicle exclusion as a dispositive defense, asserting that Erie Insurance Exchange v. Mione, 289 A.3d 524 (Pa. 2023), restored the exclusion’s enforceability.

The key issues on appeal were procedural but outcome-determinative: (1) whether Progressive could amend its answer to add the exclusion as an affirmative defense; (2) whether it could file a second summary-judgment motion premised on that defense; and (3) whether it could obtain judgment at trial on a defense it had not timely pleaded.

II. Summary of the Opinion

The Third Circuit affirmed. The court held that:

Policy exclusions are affirmative defenses, and Progressive’s failure to plead the household vehicle exclusion in its answer meant it was waived for purposes of later dispositive motions and trial.
Progressive’s attempt to justify delay by claiming Mione changed the law failed because Mione did not create a new rule; it clarified that Gallagher was limited to “de facto waiver” of stacking and did not render household exclusions “ipso facto unenforceable.”
The District Court did not abuse its discretion in denying leave to amend for undue delay under Rule 15(a), nor did it err in denying subsequent motions predicated on an unpleaded defense.

III. Analysis

A. Precedents Cited

1. Pennsylvania household exclusion and UIM background

Eichelman v. Nationwide Ins. Co., 711 A.2d 1006 (Pa. 1998): The cornerstone authority recognizing the general validity of the household vehicle exclusion. The Third Circuit relied on Eichelman to show that the exclusion was not “newly viable” after Mione; rather, it had been recognized for decades, including in scenarios where an insured seeks UIM benefits under a resident relative’s policy after operating an uninsured or separately insured household vehicle.
Gallagher v. GEICO Indemnity Co., 201 A.3d 131 (Pa. 2019): A narrower decision invalidating use of the household vehicle exclusion where it operated as a “de facto waiver” of stacking without the statutorily required waiver form. The Third Circuit emphasized Gallagher did not announce that household exclusions are categorically invalid; it addressed a specific conflict with Pennsylvania’s stacking-waiver requirements.
Erie Insurance Exchange v. Mione, 289 A.3d 524 (Pa. 2023): The Pennsylvania Supreme Court reaffirmed that Gallagher is limited to the stacking context and reiterated that household vehicle exclusions are not “ipso facto unenforceable,” expressly citing Eichelman. The Third Circuit used Mione against Progressive: it was framed as a clarification/reaffirmation, not a change that excused late pleading.
Erie Ins. Exch. v. Mione, 253 A.3d 754 (Pa. Super. 2021): Cited to show that even before the Pennsylvania Supreme Court’s 2023 Mione decision, Pennsylvania’s intermediate appellate court had already explained that Gallagher invalidated household exclusions only when used to circumvent stacking-waiver requirements. This undercut Progressive’s claim that it could not reasonably plead the defense when it answered in 2021.
Donovan v. State Farm Mut. Auto. Ins. Co., 256 A.3d 1145 (Pa. 2021): Cited for the proposition that Eichelman and Gallagher address different issues; Gallagher turns on stacking-waiver interplay. Again, this signaled that the law was already developed at the time Progressive filed its answer.
Stockdale v. Allstate Fire & Cas. Ins. Co., 441 F. Supp. 3d 99 (E.D. Pa. 2020) (quoting Butta v. GEICO Cas. Co., 383 F. Supp. 3d 426, 431) (E.D. Pa. 2019): Used to illustrate contemporaneous federal-court understanding that Gallagher and Eichelman are not in conflict because Eichelman did not involve stacking across policies.

2. Affirmative defenses, pleading, amendment, and waiver

Miller v. Bos. Ins. Co., 218 A.2d 275 (Pa. 1966) and Gen. Refractories Co. v. First State Ins. Co., 855 F.3d 152 (3d Cir. 2017): Cited for the principle that an insurer’s reliance on a policy exclusion is an affirmative defense for which the insurer bears the burden.
Gay v. Petsock, 917 F.2d 768 (3d Cir. 1990), Fed. R. Civ. P. 15(a), and Fed. R. Civ. P. 7(a): Cited to frame the general rule favoring amendment of pleadings, while recognizing answers are pleadings subject to Rule 15.
In re Fine Paper Antitrust Litig., 685 F.2d 810 (3d Cir. 1982) and Bjorgung v. Whitetail Resort, LP, 550 F.3d 263 (3d Cir. 2008): Cited for the district court’s broad discretion over docket control and amendment decisions.
Cox v. Horn, 757 F.3d 113 (3d Cir. 2014): Cited for the abuse-of-discretion standard—error of fact, law, or application.
Mullin v. Balicki, 875 F.3d 140 (3d Cir. 2017) (citing Foman v. Davis, 371 U.S. 178 (1962)): Sets out the classic grounds to deny leave to amend, including undue delay.
Adams v. Gould Inc., 739 F.2d 858 (3d Cir. 1984) and Cureton v. Nat'l Collegiate Athletic Ass'n, 252 F.3d 267 (3d Cir. 2001): Provide the undue-delay framework; the focus is on the movant’s reasons for not amending sooner.
Charpentier v. Godsil, 937 F.2d 859 (3d Cir. 1991): Supplies the waiver rule: failure to raise an affirmative defense in a responsive pleading or appropriate motion generally waives it.
Fed. R. Civ. P. 8(c): Quoted/relied on to reject Progressive’s argument that incorporating the “entire policy” into its answer sufficed; exclusions must be affirmatively stated.

3. Trial-motion standards referenced

Walter v. Holiday Inns, Inc., 985 F.2d 1232 (3d Cir. 1993), Spartan Concrete Prods., LLC v. Argos USVI, Corp., 929 F.3d 107 (3d Cir. 2019), and Sabinsa Corp. v. Creative Compounds, LLC, 609 F.3d 175 (3d Cir. 2010): Cited to explain terminology and standards for “directed verdict”/judgment as a matter of law in the bench-trial context and the appellate lens for reviewing such rulings.

B. Legal Reasoning

The court’s reasoning tracks a straightforward procedural syllogism:

A policy exclusion is an affirmative defense. The opinion treats this as settled in Pennsylvania insurance law (citing Miller v. Bos. Ins. Co. and Gen. Refractories Co. v. First State Ins. Co.).
Affirmative defenses must be pleaded. Under Fed. R. Civ. P. 8(c), the defendant must “affirmatively state” them. A generic incorporation of the policy is not enough.
Progressive did not plead the household vehicle exclusion in its answer. It filed 22 affirmative defenses but omitted the exclusion it later sought to rely on.
Progressive’s proposed excuse—intervening change in law—failed. The Third Circuit held Mione did not change the governing law; it reaffirmed the continuing enforceability of household exclusions outside the stacking-waiver scenario highlighted in Gallagher. In the court’s view, the legal basis to plead the exclusion existed long before Progressive answered and throughout the litigation (including in Erie Ins. Exch. v. Mione (Pa. Super. 2021), Donovan (Pa. 2021), and federal district decisions like Stockdale and Butta).
Undue delay justified denying amendment. Applying Rule 15(a) and the Foman/Adams/Cureton framework, the district court permissibly found that waiting nearly two years (and approaching/through trial) to add a known, central coverage defense was “undue,” especially given the absence of a true legal shift.
Waiver foreclosed dispositive motions and trial relief. Under Charpentier v. Godsil, Progressive’s failure to raise the defense timely meant it could not be revived via a second summary-judgment motion or a directed verdict/judgment as a matter of law.

Notably, the panel did not decide the ultimate merits of applying the exclusion to Rodd’s claim. Instead, the case stands for a procedural holding: even a potentially meritorious exclusion defense cannot be used if it is not timely pleaded and properly preserved.

C. Impact

Although designated “NOT PRECEDENTIAL,” the opinion offers a clear roadmap for litigants in federal insurance cases applying Pennsylvania law:

Insurers must plead exclusions early and explicitly. The household vehicle exclusion (and similar exclusions) must appear as an affirmative defense in the answer; referencing the policy generally is insufficient.
“Change in law” arguments face close scrutiny. Parties cannot treat clarifying decisions—especially those that reaffirm existing limitations—as retroactive permission to add late defenses. Here, Mione was treated as a clarification of Gallagher, not a doctrinal pivot.
Procedural waiver can decide coverage litigation. The case underscores that waiver rules are not technicalities; they can control entitlement to summary judgment and trial judgment even in coverage disputes where the exclusion may have substantial support under decisions like Eichelman.
Strategic consistency matters. Progressive’s earlier reversal of its denial after Gallagher may have been prudent risk management, but it did not relieve Progressive of pleading requirements once litigation began. A party uncertain about an exclusion’s enforceability should still plead it in the alternative to preserve it.

IV. Complex Concepts Simplified

Underinsured motorist (UIM) coverage: Coverage that can pay the insured when the at-fault driver’s liability limits are not enough to cover the insured’s injuries (see 75 Pa. Cons. Stat. § 1702).
Household vehicle exclusion: A policy clause that can bar UIM recovery for injuries sustained while occupying a vehicle owned by or regularly available to the insured or a household relative, when that vehicle is not covered for UIM under the policy at issue.
Stacking: The ability to combine UIM limits across multiple vehicles or policies. In Gallagher, the exclusion was invalid because it functioned like an end-run around statutory requirements for waiving stacked coverage.
Affirmative defense: A defense the defendant must plead and prove—often one that avoids liability even if the complaint’s factual allegations are true (here, a policy exclusion).
Undue delay (Rule 15): Not merely the passage of time, but an unjustified lateness in seeking amendment that burdens the court or unfairly disadvantages the other side; courts focus on the reasons for not acting sooner.
Waiver of defenses (Rule 8(c)): If a party does not affirmatively state an affirmative defense in its responsive pleading (or properly raise it by motion), the defense is typically lost and cannot be used later to win the case.

V. Conclusion

The Third Circuit’s decision affirms a practical, litigation-shaping rule in insurance coverage disputes: policy exclusions must be timely and specifically pleaded as affirmative defenses. Progressive’s attempt to reintroduce the household vehicle exclusion late in the case failed because Erie Insurance Exchange v. Mione did not create new law; it reiterated that Gallagher v. GEICO Indemnity Co. is confined to the stacking-waiver context and left intact the broader enforceability recognized in Eichelman v. Nationwide Ins. Co.. Even where substantive coverage law may favor an insurer, this opinion highlights that procedural preservation is indispensable.
