A battalion of Beanie Babies has marched a legal question before us. While on a quest to torch his wife Ramona’s Beanie Baby collection, Robert Sager nearly burnt down the family house. Ramona now seeks to collect under the couple’s homeowners policy with Farm Bureau for Robert’s pyromaniacal actions. The policy, however, contains an exclusion for “intentional loss” at the hand of “an insured.” In a matter of first impression, we hold Iowa’s standard fire insurance policy, as set forth in Iowa Code section 515.138 (1999), renders the exclusion unenforceable. We reverse and remand for further proceedings.
I. Facts and Prior Proceedings
The facts are stipulated. Robert Sager intentionally set a fire in the basement of a house he shared with his wife Ramona in DeWitt. Angry after Ramona told him she was ending their relationship, Robert torched Ramona’s Christmas decorations in the basement of their house. 1 The fire quickly spread, and portions of the house were soon engulfed in flames. Robert’s pyromaniacal act caused approximately $100,000 damage to the house and its contents. Not surprisingly, Robert and Ramona later divorced.
At the time of the fire, Robert and Ramona were named insureds under a homeowners policy with Farm Bureau Mutual Insurance Company. When Ramona sought payment, Farm Bureau denied her claim. To justify its nonpayment, Farm Bureau cited exclusions in the policy for “intentional loss” and “concealment or fraud.”
The “intentional loss” exclusion barred recovery for “any loss arising out of any act committed ... (l)[b]y or at the direction of an ‘insured’ ... and (2)[w]ith the intent or expectation of causing a loss.” Farm Bureau contended this exclusion precluded payment to Ramona because *10 Robert, an insured, had purposefully started the fire.
The “concealment or fraud” exclusion barred coverage where an insured
(1) Intentionally concealed or misrepresented any material fact or circumstance;
(2) Engaged in fraudulent conduct; or
(3) Made false statements;
relating to [the] insurance.
Farm Bureau denied Ramona benefits under this exclusion because its “own investigation revealed substantial inaccuracies in [Ramona’s ‘Sworn Statement in Proof of Loss’] regarding the extent of damage to personal property.” In a deposition conducted at Farm Bureau’s invitation, Robert alleged many items in Ramona’s sworn proof of loss statement were, in fact, undamaged or salvageable.
.After Farm Bureau denied her claim, Ramona sued to recover under the policy. In the district court, Ramona argued the “intentional loss” exclusion was unenforceable because it (1) did not meet the minimum provisions of Iowa’s standard fire insurance policy, as set forth in Iowa Code section 515.138 (1999), and (2) was ambiguous due to a formatting error. The district court dismissed. First, the court ruled
Vance v. Pekin Insurance Co.,
Although Farm Bureau had also argued Ramona could not recover under the policy because she had misrepresented the extent of her loss, the district court declined to “answer whether such misrepresentation bars Ramona from recovery.”
The court of appeals reversed and remanded for entry of judgment in favor of Ramona. First, the court distinguished Vance; in Vance, we were not presented with the statutory argument, i.e., whether a policy which bars an innocent coinsured spouse from recovering violates Iowa Code section 515.138, our state’s standard fire insurance policy. Pointing to the great weight of authority, the court of appeals concluded the “intentional loss” exclusion in the Sagers’ policy violated the minimum protections afforded by the statute, and was therefore unenforceable. As a result, the court did not reach whether formatting errors also rendered the exclusion unenforceable. Second, the court of appeals determined “reasonable fact finders could differ on whether the inaccuracies on Ramona’s proof of loss form rose to the level of material misrepresentations or fraud.” Since this case was tried on stipulated facts, however, the court did not remand. The court of appeals reasoned the district court was in no better position than it to judge credibility, making a remand inefficient. The court simply held “Farm Bureau cannot establish the applicability of the concealment of fraud exclusion as a matter of law, [and therefore] it is not entitled to affirmance on this alternate ground.”
Farm Bureau sought further review, which we granted. Farm Bureau contends the court of appeals (1) erred in holding Iowa Code section 515.138 renders the intentional loss exclusion in the policy unenforceable and (2) failed to hold Ramona’s misrepresentations “material.” Should we affirm the court of appeals’ decision, Farm Bureau also asks us to provide guidance on how much Ramona is entitled to recover.
II. Standard of Review
Our review is for errors at law. Iowa R.App. P. 6.4. Factual findings *11 made by the trial court are binding on appeal if supported by substantial evidence. Id. 6.14(6)(a). This case was tried on stipulated facts in the district court. That is,
To save expense, and to simplify the issue, the facts were agreed upon by the parties, upon which the court should render judgment. The parties, in effect, said to the court, “these are the facts, and now we wish judicially to know what are the rights of the parties thereunder.”
Logan v. Hall,
III. Merits
A. The Problem of the Innocent Coinsured Spouse
1. Vance
In
Vance v. Pekin Insurance Company,
we held that where one spouse had intentionally set fire to the family home, an innocent coinsured spouse could not recover under a homeowners policy which clearly and unequivocally excluded coverage from losses resulting from the intentional acts of
“an insured.”
Vance
contained an intentional loss exclusion similar to the case at bar. In
Vance,
we interpreted the phrase “an insured” in the policy to mean “an unspecified insured” who intentionally sets fire to the house.
2. Iowa Code § 515.138
After
Vance
was decided, however, a new question arose in other jurisdictions: If an innocent coinsured spouse is denied coverage under the express terms of the policy, do those policy provisions then violate the mandatory coverage provisions in state statutes? Citing a relatively recent Minnesota decision,
Watson v. United Services Automobile Association,
Found in Iowa Code section 515.138, our state’s standard fire insurance policy “lists various permissible standard provisions for fire policies.... ”
Thomas v. United Fire & Cas. Co.,
It shall be unlawful for any insurance company to issue any policy of fire insurance upon any property in this state ... different from the standard form of fire insurance policy herein set forth.... An insurer may issue a [different] policy ... if such policy includes provisions with respect to the peril of fire which are the substantial equivalent of the minimum provisions of such standard policy....
Iowa Code § 515.138. Insurance companies which offer or issue policies “other or different from the standard form” are guilty of a simple misdemeanor.
Id.
§ 515.140. Such policies, however, nonetheless remain binding upon the insurance company.
Id.; cf. A.A. Cooper Wagon & Buggy Co. v. Nat’l. Ben Franklin Ins. Co.,
Notwithstanding the principle that the meaning of an insurance contract is generally determined from the language of the policy, statutory law may also affect our interpretation of policy provisions .... [W]hen a policy provision conflicts with a statutory requirement, the policy provision is ineffective and the statute controls.
Lee v. Grinnell Mut. Reins. Co.,
The standard fire insurance policy itself is too lengthy to set forth here. As we have previously pointed out, however, “[t]he standard type of insurance policy is what is generally known as the New York type. It was first adopted in the state of New York and has been followed in Iowa and many other states since its original adoption.”
Olson Enters., Inc. v. Citizens Ins. Co.,
When interpreting our standard fire insurance policy, we look to the decisions of other jurisdictions with a similar policy.
See, e.g., Olson,
[WJhile there is no specifically designated intentional acts exclusion in the [standard policy], it includes other provisions dealing generally with the insurer’s right to void coverage based upon conduct of “the insured.” In each instance, the standard policy uses language indicative of a several obligation whereby the insured bears the responsibility for his or her own conduct. We find no provision ... creating a joint obligation whereby the wrongful actions of one insured could prejudice the rights of an innocent co-insured.
Volquardson,
Farm Bureau contends the foregoing cases are distinguishable because of a difference in the Iowa statute. As indicated, Iowa’s statute only prohibits those policies which are not the “substantial equivalent” of the statutory policy. Iowa Code § 515.138. Although this “substantial equivalent” provision is, so far as we can tell, somewhat peculiar to Iowa, it is not unique.
See
1959 Iowa Acts ch. 329 (adding “substantial equivalent” proviso to standard fire policy). In
Volquardson,
for example, the Nebraska Supreme Court rejected an identical claim.
[t]here is an obvious substantive difference between joint and several obligations of multiple insureds with respect to a coverage exclusion based upon conduct. Where the obligation is joint, commission of a proscribed act by one insured voids coverage as to all. However, where the obligation is several, the proscribed conduct defeats the policy rights of the insured who committed the act but not those of an innocent coin-sured.
Volquardson,
Lastly, we reject Farm Bureau’s contention that accepting Ramona’s argument “overrules” Vance. Farm Bureau maintains we must assume that we considered and rejected Ramona’s statutory argument in Vance, because in that case we denied recovery to an innocent coinsured spouse—notwithstanding the fact Iowa Code section 515.138 was “on the books” at that time. Farm Bureau points out that Vance was written in response to a certified question from the federal district court; certified questions, it alleges, are different than cases taken on direct appeal, because our review in certified questions is not limited to issues raised, briefed, and argued by the parties.
We reject this argument. We were not presented with the standard fire insurance policy in Vance, and our answers to certified questions are no different than our decisions on direct appeal, insofar as both proceedings are adversarial. In either sort of case, we generally consider only questions argued by the parties; answers to certified questions should not be understood as all-encompassing court-approved treatises on a given body of law.
Farm Bureau’s argument also ignores the organic nature of law: the law develops over time, in no small part due to the ability of lawyers to develop new arguments. Unfortunately, the best arguments are not marshaled before us in every case. We do not, then, “overrule”
Vance,
because in that case we were not presented with the statutory argument. Instead, our decision today simply “adds a second step to the contractual analysis.”
Watson,
Because we find the intentional loss provision is unenforceable against Ramona, we need not decide whether it is also rendered unenforceable due to ambiguity.
B. Concealment or Fraud Exclusion
Having determined the “intentional loss” provision is unenforceable against Ramona, it must still be determined whether she is barred from recovery under the policy’s “concealment or fraud” exclusion. Farm Bureau argues Ramona is barred from recovery because she materially misrepresented the extent of personal property destroyed in the fire. In support of its argument, Farm Bureau cites
Webb v. American Family Mutual Insurance Co.,
in which we denied recovery where an insured had “intentionally misrepresented the extent of personal property destroyed and ... the misrepresentation was material.”
On this issue, the district court made only a limited number of factual findings. The record contains contradictory evidence about the condition of numerous items of personal property left in the house after the fire. The court expressly found Ramo
*15
na submitted a proof of loss form which “contained a substantial number of items ... not destroyed in the fee.” The court later characterized Ramona’s actions as a “misrepresentation,” but regrettably declined to “answer whether such misrepresentation bars Ramona from recovery.”
See id.
at 811 (concealment or fraud clause will not void policy unless inaccuracies in the proof of loss form were made with intent to defraud);
Goldstein v. St. Paul Fire & Marine Ins. Co.,
The procedural posture of this case, then, is manifestly unlike
Webb.
In
Webb,
a jury expressly found the insured had “with intent to defraud, concealed a material fact or circumstance as to the extent of the personal property destroyed.”
As indicated, appellate review is “limited to assigned error in the district court’s application of law pertinent to the controversy.”
Stewart,
In a final assignment of error, Farm Bureau contends the court of appeals failed to provide guidance on Ramona’s interest in the loss and how much she is entitled to recover. Because we do not decide whether Ramona will ultimately recover under the policy, we do not reach this issue. A ruling on this issue is too speculative at this time, and, in any event, must initially be made by the trial court.
See Wilson v. Ribbens,
IV. Conclusion
We hold Iowa’s standard fire insurance policy renders unenforceable an “intentional loss” exclusion clause in the Sagers’ policy which would otherwise preclude Ramona from collecting. In this respect, we affirm the court of appeals, and reverse the district court. We remand for factual findings and a legal determination as to whether Ramona is barred from recovery under the concealment or fraud exclusion in her Farm Bureau policy.
*16 DECISION OF COURT OF APPEALS AFFIRMED IN PART AND VACATED IN PART; DISTRICT COURT JUDGMENT REVERSED; REMANDED WITH INSTRUCTIONS.
Notes
. At a deposition conducted months later, Robert described the scene and his subsequent actions as follows:
She had Beanie Babies everywhere and I was sick of them sons of bitches and I decided I was going to barbecue them. I had a big brush pile that I was going to burn outside and I had decided I was going to get all her Beanie Babies and take them out and barbecue the sons of bitches and went to get the charcoal lighter. Christmas has always been another big issue between us just because, you know, she sees it differently than I do, and I went in the basement to get the charcoal lighter and take it upstairs and fry her Beanie Babies and all her Christmas stuff was sitting there and I sprayed some charcoal lighter on her Christmas stuff and threw a couple of matches at it and it flared up a lot faster than I thought it was going to....
According to Ramona, 150 Beanie Babies and Buddies perished in the fire. She claimed $1100 in damages for these collectible dolls.
. Although Farm Bureau and the court of appeals at times approached the issue as whether Ramona's statements are ''material,” the question is whether Ramona’s actions demonstrate an intent to defraud Farm Bureau. "Personal property in an insured’s home is 'material’ insofar as it is the object of the insurance policy which covers it.”
Webb v. Am. Family Mut. Ins. Co.,
