Iowa’s Bitcoin ATM Refund Law Does Not Apply Retroactively to Preenactment Fraud Transactions

1. Introduction

The Iowa Supreme Court held that Iowa Code section 533C.1004, enacted in 2025 to combat cryptocurrency fraud, does not impose refund obligations on Bitcoin ATM transactions completed before its enactment and applicability date. Applying its refund provision to a 2024 transaction would attach a new legal consequence to past conduct, contrary to Iowa’s statutory presumption against retroactivity.

The dispute concerned $11,500 that Gary VanderWerf deposited into a Bitcoin Depot ATM after being deceived by unidentified fraudsters. Bitcoin Depot supplied the corresponding bitcoin, which VanderWerf directed to the fraudsters’ wallet. Police recovered the cash from the ATM, but not the bitcoin. After the investigation ended, Bitcoin Depot sought return of the seized cash under Iowa Code chapter 809.

The district court denied that application because the newly enacted consumer-protection statute potentially required Bitcoin Depot to refund VanderWerf. The supreme court reversed. Its four-justice majority resolved the case through statutory retroactivity principles. Three justices concurred in the judgment on a different ground: even an enforceable refund obligation would not give VanderWerf an ownership or possessory interest in the particular cash seized from the ATM.

The decision therefore presents two distinct questions: when a new statutory liability may govern earlier conduct, and whether a personal claim for payment can defeat another person’s right to recover specific property. Only the first supplied the majority’s merits holding.

2. Background and Procedural History

The transaction and seizure

On August 12, 2024, VanderWerf deposited $11,500 into a Bitcoin Depot ATM in Cedar Falls. Before transacting, he accepted terms providing that deposited cash became Bitcoin Depot’s property in exchange for bitcoin supplied from its inventory. The ATM also warned against scams, described transactions as final and irreversible, and required customers to send bitcoin only to wallets they controlled.

Despite those warnings, VanderWerf designated a wallet controlled by fraudsters. Bitcoin Depot completed the requested transfer. After VanderWerf reported the fraud, police executed a search warrant on August 15 and seized $11,500 from the ATM. Bitcoin Depot assisted the investigation, but the transferred bitcoin was never recovered. The investigation eventually closed without charges.

The intervening legislation

In 2025, the legislature enacted section 533C.1004 to regulate digital financial asset transaction kiosks. The legislation contained an immediate-effect provision dated May 19, 2025, but separately specified that it applied to operators on or after July 1, 2025.

The statute introduced transaction limits, disclosure requirements, and refunds for qualifying fraud victims. For new consumers, subsection (8) requires a refund for qualifying transactions during the initial thirty-calendar-day period, subject to conditions including timely reporting to the operator and a government or law enforcement agency, and submission of proof of fraud. The enactment contained no express provision extending those obligations to earlier transactions.

The competing proceedings

Bitcoin Depot applied for return of the seized cash on July 18, 2025. At the hearing, the county attorney acknowledged that the investigation no longer required the money and that the material facts matched the supreme court’s recent Bitcoin Depot ownership precedent. VanderWerf attended without counsel and requested reimbursement, but did not file a competing written claim in that proceeding.

The district court nevertheless denied Bitcoin Depot’s application. It reasoned that section 533C.1004 was in effect when the application was filed and that its new-consumer refund provision displaced Bitcoin Depot’s entitlement. The court did not then order payment to VanderWerf.

While Bitcoin Depot’s appeal was pending, VanderWerf obtained a separate December 18, 2025 order directing release of the money to him. Bitcoin Depot received no notice of that proceeding. The State agreed to the release, and the cash was paid out. The supreme court learned of this development shortly before oral argument.

During the appeal, Bitcoin Depot entered Chapter 11 bankruptcy. GDP Holdings d/b/a Coinflip acquired the claim through an asset purchase agreement and was substituted as appellant. The court continued using “Bitcoin Depot” for clarity.

3. Summary of the Opinion

• The State could appear as appellee. It had an interest in the contested disposition of property seized and held during its criminal investigation.
• The appeal was not moot. Reversal could affect Bitcoin Depot’s ability to challenge the later release order or pursue relief concerning the distributed money.
• The refund statute did not govern the 2024 transaction. Applying it would impose a new liability for conduct preceding its enactment, without the express legislative authorization required by Iowa Code section 4.5.
• Bitcoin Depot was entitled to the seized cash under existing precedent. The district court therefore erred in denying its application.
• Further proceedings were necessary. The supreme court did not determine the validity of the later release order or the remedy for cash already paid to VanderWerf.

Justice Waterman wrote for Chief Justice Christensen and Justices Mansfield and McDermott. Justice Oxley, joined by Justices McDonald and May, agreed with reversal but considered the retroactivity question unnecessary. Thus, all seven justices agreed on the judgment, while dividing four to three over the controlling rationale.

4. Analysis: The Majority’s Legal Reasoning

A. The relevant event was the transaction, not the application

The district court and the State focused on the date Bitcoin Depot requested return of its property. Because the new law already applied to operators by then, they treated its use as prospective.

The majority rejected that characterization. VanderWerf’s claimed entitlement arose entirely from the fraudulent transaction completed in August 2024. At that time, Bitcoin Depot had no statutory duty of the kind later created to reimburse him. Using the new law to deny recovery of its cash would therefore attach a new consequence to an already completed transaction.

This distinction is central to the precedent. A statute does not operate prospectively merely because a court applies it after its effective date. The inquiry concerns the conduct or event to which the statute attaches legal consequences.

B. Iowa’s three-stage retroactivity inquiry

The court applied a three-stage framework:

1. Is the proposed application actually retrospective?
2. If so, does the statute authorize retrospective application?
3. If it does, does substantive law nevertheless prohibit that application?

The proposed application satisfied the first stage because it would create a refund obligation absent when the transaction occurred. The majority also noted the statute’s potential civil penalties, including penalties of up to $10,000 per violation, as further evidence of newly imposed legal consequences. It did not impose any penalty in this case.

At the second stage, Iowa Code section 4.5 controlled: “A statute is presumed to be prospective in its operation unless expressly made retrospective.” Section 533C.1004 contained no express retroactivity language. The court therefore concluded that the legislature had not authorized its application to VanderWerf’s earlier transaction.

Having resolved the case at that stage, the majority did not reach the third stage. It made no constitutional ruling about whether retroactive cryptocurrency regulation would violate due process.

C. Settled expectations supported the statutory interpretation

The majority explained why retrospective liabilities are disfavored: parties cannot adjust completed conduct to comply with obligations created later. If Bitcoin Depot had known of the refund obligation in 2024, it might have adopted additional safeguards, such as transaction caps, delayed transfers, or wallet-control authentication.

Those examples did not establish new operational duties or findings of negligence. They illustrated the lost opportunity to respond to a legal risk before it arose. The court’s concern was that a later statute should not unexpectedly alter the consequences of a completed transaction without legislative direction.

D. The State’s textual arguments did not establish retroactivity

“New” and “existing” consumers

The State argued that the distinction between new and existing consumers implied coverage of transactions preceding the statute. The majority disagreed. The legislature could distinguish consumers by experience while regulating their transactions prospectively. Recognizing an existing customer relationship does not necessarily impose liability for every earlier transaction in that relationship.

Transaction limits and refunds formed a coordinated scheme

The statute limited daily deposits or withdrawals to $1,000 and imposed an additional $10,000 limit during a new consumer’s first thirty days. Those safeguards plainly could not govern deposits already completed. VanderWerf’s single $11,500 deposit illustrated the problem.

The majority declined to “slice and dice” the statute by applying refund obligations retrospectively while treating the associated risk-limiting provisions as prospective. Its reasoning treated the safeguards and liabilities as interrelated parts of the legislative scheme.

The chapter’s older applicability provision did not control

The State also relied on section 533C.1003, which broadly referenced money transmission on or after October 1, 2003. The court held that the specific, later-enacted July 1, 2025 applicability provision for the kiosk legislation controlled over that broader language.

Iowa Code sections 4.7 and 4.8 supported that conclusion: a specific provision ordinarily controls over a conflicting general provision, and a later enactment prevails when provisions cannot be reconciled.

Other amendments demonstrated how to provide retroactivity expressly

The legislature had expressly made several 2024 amendments to the same chapter retroactive to July 1, 2023. Its omission of comparable language from the 2025 kiosk legislation reinforced the conclusion that section 533C.1004 operated only prospectively.

E. The State’s participation was proper

Although the State sought neither forfeiture nor continued evidentiary retention, the majority treated it as an interested party in the disposition of money it had seized and held. Iowa Code section 13.2(1)(a) requires the attorney general to defend appellate causes in which the State is a party or interested.

The court also noted that Bitcoin Depot had not objected to the county attorney’s participation below. It denied the motion to strike the State’s appellate appearance. This was a ruling about the State’s participation, not recognition of any State ownership interest in the cash.

F. Distribution of the cash did not eliminate the controversy

The subsequent payment to VanderWerf complicated the available relief but did not make the appeal academic. Reversal could preserve Bitcoin Depot’s opportunity to challenge the later order or argue that the State was liable for the cash’s value. Affirmance could effectively foreclose those avenues.

The majority did not decide whether those arguments would succeed. It also did not conclusively invalidate the later order. Questions concerning that order, the consequences of the pending appeal, and available remedies were left for the district court.

The State faulted Bitcoin Depot for failing to obtain a stay or post an appeal bond. The court rejected that criticism: the appealed ruling merely denied Bitcoin Depot’s application and did not direct payment to VanderWerf. Bitcoin Depot did not need a bond or stay to protect its appeal from that denial while the State still held the money.

5. The Concurrence: A Refund Claim Is Not an Interest in Particular Cash

Justice Oxley identified what she considered a logically prior issue. Even assuming section 533C.1004 applied, its refund obligation did not alter ownership of the deposited cash. Consequently, its retroactivity should not have been addressed.

A. Ownership and payment obligations are different rights

Under the transaction terms, Bitcoin Depot became owner of the cash when it supplied the purchased bitcoin. Section 533C.1004 required qualifying refunds but did not invalidate transactions affected by third-party fraud, reverse that transfer of ownership, or create a lien on deposited cash.

For the concurrence, the victim’s entitlement was therefore, at most, an unsecured claim against the operator. Such a claim seeks payment from a debtor; it does not itself establish ownership of any particular asset belonging to that debtor.

B. Chapter 809 concerns interests in the seized property

The concurrence emphasized chapter 809’s focus on immediate possession of identified property. Applicants must describe the items sought, their interest in them, and the grounds for return. Claims to the same property ordinarily must be heard together.

Because VanderWerf’s hypothetical refund entitlement did not create an interest in the seized banknotes, it could not defeat Bitcoin Depot’s superior possessory claim. The concurrence also observed that VanderWerf had not filed the required written competing claim in Bitcoin Depot’s proceeding. His later application in a separate case was a different procedural development.

C. The cash was not property whose possession was prohibited by law

The State relied on section 809.5’s exception for property whose possession is “prohibited by law.” Justice Oxley explained that this language concerns unlawful possession, including inherently illegal items and otherwise lawful items rendered unlawful by their use or the possessor’s status.

Nothing in the refund statute made Bitcoin Depot’s possession of its cash illegal. Owing a refund was not equivalent to possessing contraband. The concurrence would therefore have ordered reversal without interpreting the statute’s temporal reach.

Precedential distinction: This property-versus-debt analysis was the position of three justices concurring in the judgment. The majority expressly declined to decide whether even a valid refund claim could defeat a chapter 809 application. The concurrence should not be presented as a holding of the court.

6. Precedents Cited and Their Influence

A. Ownership of Bitcoin ATM deposits and standards of review

Bitcoin Depot Operating, LLC v. Carlson (In re Property Seized for Forfeiture from Bitcoin Depot Operating, LLC), 21 N.W.3d 157 (Iowa 2025)

This was the central substantive precedent. A fraud victim purchased bitcoin and directed it to a third party’s wallet; police then seized the cash deposited into the ATM. The court held that Bitcoin Depot had the greater right to possession. Without evidence that it knew of the customer’s duress, the contract was not avoided and the cash remained its property.

The majority treated that decision as controlling once the new statute was excluded. The concurrence regarded it as controlling regardless of retroactivity because a refund obligation did not change ownership. The earlier case also established the equitable character and de novo review of the return proceeding. Its rejection of an analogy to recovering stolen goods from a pawnbroker reinforced the distinction between the transferred bitcoin and the deposited cash.

Standard Water Control Sys., Inc. v. Jones, 938 N.W.2d 651 (Iowa 2020)

This decision supplied the standard for statutory interpretation: correction of errors at law. The court distinguished that legal review from its de novo review of the underlying equitable proceeding.

B. Retroactivity and statutory construction

Miller v. State, 18 N.W.3d 498 (Iowa 2025)

Miller v. State was the majority’s principal methodological authority. It restated the three-stage retroactivity inquiry and emphasized section 4.5’s express-language requirement. Its treatment of the Fraud in Assisted Reproduction Act supplied a close analogy: absent language reaching earlier conduct, a newly created liability operated prospectively. It also supported declining constitutional analysis after statutory interpretation resolved the dispute.

Hedlund v. State, 991 N.W.2d 752 (Iowa 2023)

This case supplied the three-stage framework quoted through Miller v. State and explained the fairness concerns underlying prospective application. Its emphasis on settled expectations and the opportunity to conform conduct helped explain why posttransaction refund liability would be retrospective.

Hrbek v. State, 958 N.W.2d 779 (Iowa 2021)

Quoted through Hedlund v. State, this decision defined retrospective operation as applying a new rule, standard, or consequence to an earlier act or omission. That definition directed attention away from the 2025 application and toward the completed 2024 transaction.

Nahas v. Polk County, 991 N.W.2d 770 (Iowa 2023), and Doe v. W. Dubuque Cmty. Sch. Dist., 20 N.W.3d 798 (Iowa 2025)

The court cited Nahas v. Polk County for the proposition that retrospective applicability is a question of statutory interpretation. It identified Doe v. W. Dubuque Cmty. Sch. Dist. only to disclose that Nahas v. Polk County had been overruled on other grounds. The opinion did not draw a separate substantive rule from Doe v. W. Dubuque Cmty. Sch. Dist..

Iowa Comprehensive Petroleum Underground Storage Tank Fund Bd. v. Shell Oil Co., 606 N.W.2d 370 (Iowa 2000)

The State relied on this environmental-liability decision, which permitted retrospective application of legislation addressing petroleum leaks. The majority distinguished its express reference to “past and existing petroleum leaks.” The kiosk statute contained no comparable reference to past fraud; its distinction between new and existing consumers did not perform the same function.

Me. Yankee Atomic Power Co. v. United States, 44 Fed. Cl. 372 (1999)

This authority concerned the foreseeability of additional regulation in heavily regulated industries and its relevance to due process. The majority explained that the State’s similar argument belonged at the constitutional third stage. Because legislative authorization for retroactivity was absent, that issue was not reached.

C. Mootness, appellate jurisdiction, and the later distribution

Riley Drive Ent. I, Inc. v. Reynolds, 970 N.W.2d 289 (Iowa 2022)

This decision established mootness as a threshold issue and permitted consideration of matters technically outside the district court record when deciding it. That allowed consideration of the separately entered release order. Although the State invoked the public-importance exception discussed in this precedent, the court found a live controversy and did not need that exception.

Bribriesco-Ledger v. Klipsch, 957 N.W.2d 646 (Iowa 2021)

This case required appellate courts to police their jurisdiction independently. Accordingly, the parties’ shared preference for a merits decision did not relieve the court of examining mootness.

Homan v. Branstad, 864 N.W.2d 321 (Iowa 2015)

Quoted through Riley Drive Ent. I, Inc. v. Reynolds, this case explained that courts ordinarily decline questions whose answers no longer matter because circumstances have changed. The possible consequences of reversal distinguished this appeal from such an academic dispute.

Republic Nat'l Bank of Mia. v. United States, 506 U.S. 80 (1992)

This decision held that transfer of the property at issue does not itself divest an appellate court of jurisdiction in an in rem forfeiture action. The majority used that principle to reject the argument that payment of the cash necessarily ended appellate jurisdiction. It did not use the case to establish a particular repayment remedy.

Freer v. DAC, Inc., 929 N.W.2d 685 (Iowa 2019), and Wolf v. City of Ely, 493 N.W.2d 846 (Iowa 1992)

These cases supplied the general rule that perfecting an appeal removes the district court’s authority over matters pending on appeal. They supported Bitcoin Depot’s potential challenge to the later order concerning the same cash. The majority nevertheless left the validity and consequences of that order for initial determination on remand.

D. Authorities supporting the concurrence’s property-rights analysis

State v. McCollaugh, 5 N.W.3d 620 (Iowa 2024)

The concurrence invoked this case’s instruction to interpret statutory language as written. A statutory right to a refund could not be expanded into an unstated lien, ownership interest, or rescission of the original transaction.

United States v. $20,193.39 U.S. Currency, 16 F.3d 344 (9th Cir. 1994)

This federal forfeiture decision distinguished unsecured creditors from creditors with interests in particular assets. It supported the concurrence’s conclusion that a general refund claim did not establish an interest in the seized cash.

United States v. $461,940.00 in U.S. Currency, 562 F. Supp. 3d 645 (C.D. Cal. 2021)

This decision likewise required a specific interest in forfeited property. It reinforced the concurrence’s distinction between a claim against an owner and a claim to that owner’s identified asset. The federal forfeiture authorities were analogies, not direct interpretations of Iowa’s return statute.

In re Prop. Seized from Wagner, 482 N.W.2d 160 (Iowa 1992)

An ex-wife’s child-support judgment did not establish an interest in seized funds where garnishment had not occurred before seizure. This Iowa authority demonstrated that even a judgment debt does not automatically confer rights in particular currency.

Commonwealth v. One Hundred Twenty-five Thousand One Hundred Ninety-one Dollars, 921 N.E.2d 997 (Mass. App. Ct. 2010)

This case denied an unsecured judgment creditor intervention in a forfeiture proceeding for lack of the required property interest. It supplied additional persuasive support for keeping personal payment claims separate from asset-specific proceedings.

In re 1972 Euclid Ave., No. 07-0552, 2008 WL 2039310 (Iowa Ct. App. May 14, 2008)

This case supported the importance of filing a claim. An alleged victim’s asserted entitlement to seized trees could not defeat the applicant’s request when the victim had not used the statutory claims procedure. The concurrence applied that reasoning to VanderWerf’s failure to file a written claim in the original proceeding.

State v. Ludtke, 446 N.W.2d 797 (Iowa 1989)

This decision distinguished inherently unlawful property from otherwise lawful property rendered unlawful by its use. The concurrence used those categories to explain why the “prohibited by law” exception did not encompass ordinary cash merely because its owner might owe a refund.

In re Prop. Seized for Forfeiture from Clark, No. 13-0062, 2014 WL 2601503 (Iowa Ct. App. June 11, 2014)

The court there rejected forfeiture of glass pipes without evidence satisfying the statutory definition of drug paraphernalia. The concurrence used it to illustrate that unlawful possession depends on a statute’s actual reach, not a general association with wrongdoing.

State v. McGuire, 921 N.W.2d 77 (Neb. 2018)

This decision expressed the principle that government must return property when its legitimate interests in retaining it have ended. It supported the concurrence’s conclusion that, absent another property interest or unlawful possession, the closed investigation left no basis to retain Bitcoin Depot’s cash.

7. Impact and Limits of the Decision

For statutory retroactivity

The opinion reinforces that courts must identify the event generating liability rather than simply apply whatever law exists when a case is heard. A later application, demand, or hearing does not by itself permit new substantive consequences for completed conduct.

It also provides a drafting lesson: legislation intended to reach earlier transactions should say so expressly. General regulatory purposes, historical applicability language elsewhere in a chapter, and references to existing customers did not supply the necessary authorization here.

For cryptocurrency operators and consumers

The ruling protects operators against this statute’s newly created refund liabilities for preenactment transactions. It does not exempt them from prospective transaction limits, disclosures, or qualifying refund duties. Nor does it eliminate every possible remedy for earlier fraud; it resolves the applicability of this particular statutory scheme.

For consumers, the decision separates recovery of the bitcoin lost to fraud from recovery of cash exchanged for that bitcoin. Under the controlling ownership precedent, recovery of cash from an ATM does not automatically establish the victim’s right to that cash.

For seized-property practice

The separate release proceeding highlights the need to identify competing claims, notify affected parties, and account for pending appeals before distributing contested property. The concurrence’s discussion of chapter 809’s consolidated-claim procedure is especially relevant, although the majority did not decide the validity of the later proceeding.

Questions left open

• Whether VanderWerf satisfied the refund statute’s notice and proof requirements.
• Whether a valid statutory refund claim can defeat a chapter 809 application for specific cash.
• Whether constitutional limits would bar expressly authorized retroactive regulation.
• Whether the later release order was invalid or otherwise ineffective against Bitcoin Depot.
• What relief is available after the State has distributed the money.

The concurrence offers a developed answer to the second question, but that answer did not command a majority.

8. Complex Concepts Simplified

Retroactive or retrospective application

Using a new law to change the legal consequences of something completed before the law applied. The opinion uses these terms interchangeably.

Prospective application

Applying a law to conduct occurring after its applicable starting date.

In rem proceeding

A proceeding focused on rights in identified property—here, the seized cash—rather than simply whether one person owes another money.

Unsecured claim

A right to demand payment without a special legal interest in a particular asset. On the concurrence’s view, a refund obligation alone falls into this category.

Lien

A legally recognized claim against particular property that secures payment of an obligation. The concurrence found no statutory lien on the deposited cash.

Mootness

A case becomes moot when deciding it can no longer affect the parties’ rights. Possible relief after reversal kept this appeal live.

De novo review

Independent appellate review of an equitable case. Statutory interpretation remained subject to the separate standard of correction of legal errors.

Contraband

Property whose possession is unlawful, either inherently or because of its use or the possessor’s circumstances. A disputed obligation to pay money does not itself make cash contraband.

9. Conclusion

The controlling rule is that Iowa’s 2025 Bitcoin ATM refund statute does not impose new refund consequences on the 2024 transaction at issue. The absence of express retroactivity language, reinforced by the statute’s specific applicability date and coordinated safeguards, required prospective operation.

The court consequently recognized Bitcoin Depot’s entitlement under existing ownership precedent and reversed. Recovery after the cash’s separate distribution remains a matter for remand. The concurrence adds an important but nonbinding distinction: owing a refund is not necessarily the same as surrendering ownership of particular seized cash.
