Auction-Price Baseline for Just Compensation in Fairly Conducted Tax Sales (and No Eighth Amendment “Fair Market Value” Requirement)

1) Introduction

Case: Pung, Personal Representative of the Estate of Pung v. Isabella County, Michigan, 609 U. S. ____ (2026).
Court: U.S. Supreme Court (Opinion by JUSTICE ALITO).
Posture: Certiorari to the Sixth Circuit; judgment vacated and remanded.

This case sits in the wake of Tyler v. Hennepin County, 598 U. S. 631 (2023), which recognized that when the government keeps value beyond what is needed to satisfy a tax debt, the owner has a protected property interest in the surplus proceeds. Here, the Pung family’s home—assessed at $194,400—was sold at public auction for $76,008 to satisfy a $2,241.93 tax delinquency. The litigation asked whether the Constitution requires more than return of surplus proceeds when the auction price is below the home’s “hypothetical fair market value.”

Core issues:

  • Takings Clause baseline: Is “just compensation” after a tax foreclosure sale measured by the auction sale price (with surplus returned), or by a hypothetical fair market value?
  • Excessive Fines Clause: Does the Eighth Amendment require payment up to fair market value on the theory that keeping less constitutes an “excessive fine”?
  • Procedural fairness carve-out (left open): What happens if the tax-sale process is allegedly “unfair”?

Parties: Petitioner Michael Pung, personal representative of the Estate of Timothy Scott Pung, versus Respondent Isabella County, Michigan.

2) Summary of the Opinion

The Court holds that the proper constitutional baseline for measuring “just compensation” in the tax-sale context is the tax-auction sale price, not the property’s hypothetical fair market value, at least when the sale is “fairly conducted in light of our country’s history of tax sales.” The Court further holds that the Eighth Amendment Excessive Fines Clause does not require a fair-market-value payout following such a sale.

The Court thus rejects Pung’s attempt to constitutionalize a “fair market value” guarantee for tax foreclosure auctions. However, it expressly declines to decide Pung’s newly emphasized arguments that the County’s procedures were unfair, leaving the Sixth Circuit to determine on remand whether those arguments were preserved and, if so, whether they have merit.

3) Analysis

3.1 Precedents Cited (and How They Shape the Holding)

(a) The Tyler framework—and its limit

Tyler v. Hennepin County, 598 U. S. 631 (2023), is the doctrinal starting point. In Tyler, the Court recognized a protected property interest in the surplus proceeds of a tax sale. Pung clarifies what Tyler did not decide: whether “just compensation” must be keyed to a property’s fair market value even when an auction yields less.

(b) Historical federal statutes and early practice

The opinion relies heavily on continuity between English practice, early federal statutes, and state practice: tax-sale regimes historically required return of the “overplus” (surplus proceeds) after paying the tax debt, costs, and charges—but not payment up to fair market value. The Court treats that tradition as powerful evidence of what the Takings Clause permits in the specific tax-collection setting.

(c) This Court’s tax-sale surplus cases: United States v. Taylor and United States v. Lawton

United States v. Taylor, 104 U. S. 216 (1881), and United States v. Lawton, 110 U. S. 146 (1884), supply the canonical rule: government may sell to satisfy tax debts but must return the surplus. Lawton is especially important because it ties surplus retention to constitutional wrong: “To withhold the surplus from the owner would be to violate the Fifth Amendment….” Pung uses these cases to define the constitutional floor and ceiling: surplus must be returned, but nothing in these cases suggests a fair-market-value top-up is required.

(d) Reasonable limits on surplus rights: Nelson v. City of New York

Nelson v. City of New York, 352 U. S. 103 (1956), is invoked to show that even the right to surplus can be subject to procedural constraints (e.g., reasonable time limits). That supports the broader premise that the Takings Clause analysis in tax enforcement is sensitive to historically accepted administrative mechanisms rather than purely theoretical “full value” recovery.

(e) Auction price as legally operative value in forced-sales contexts: BFP v. Resolution Trust Corporation

BFP v. Resolution Trust Corporation, 511 U. S. 531 (1994), though a bankruptcy/foreclosure decision, is used for a crucial analogy: where state-law foreclosure requirements are satisfied, “reasonably equivalent value” can be the price “in fact received” at foreclosure sale. The Court draws from BFP to resist importing fair-market-value assumptions into a forced-sale framework that is structurally different from ordinary market transactions.

(f) Eminent domain cases invoked—then cabined

Pung relied on eminent-domain doctrine (where fair market value is often the default). The Court acknowledges Knick v. Township of Scott, 588 U. S. 180 (2019), and Penn-East Pipeline Co. v. New Jersey, 594 U. S. 482 (2021), but emphasizes that “just” compensation is context-dependent. It cites United States v. 564.54 Acres of Monroe and Pike County Land, 441 U. S. 506 (1979), for the proposition that the Court has “refused to designate market value as the sole measure of just compensation,” especially where the standard is inappropriate or would cause “manifest injustice.”

(g) State authorities and “multiple chattels” cases rejected as inapposite

The Court rejects reliance on Rafaeli, LLC v. Oakland County, 505 Mich. 429, 485-522, 952 N. W. 2d 434, 466-487 (2020) (Viviano, J., concurring), as a late-arising, state-constitutional concurrence. It also distinguishes a line of cases involving sales of multiple distinct items beyond what was necessary: Cone v. Forest, 126 Mass. 97 (1879); Lane v. Roma Lumber Co., 234 Ala. 551, 176 So. 283 (1937); Denton v. Caroll, 4 App. Div. 532, 40 N. Y. S. 19 (1896); Seekins v. Goodale, 61 Me. 400 (1873). Those cases involved discrete items (e.g., cows) and over-seizure by selling more units than needed. Here, the County sold a single parcel of real property, and Pung did not argue subdivision was feasible.

(h) Incorporation/historical persistence: Chicago, B. & Q. R. Co. v. Chicago

The Court draws an institutional inference from Chicago, B. & Q. R. Co. v. Chicago, 166 U. S. 226 (1897): after incorporation against the States, longstanding tax-sale practices persisted. The Court treats that persistence as evidence against a novel interpretation that would render tax sales “untenable.”

(i) Excessive Fines Clause: Austin v. United States and United States v. Bajakajian

For the Eighth Amendment, the Court relies on Austin v. United States, 509 U. S. 602 (1993), for the proposition that forfeiture can be a “fin[e]” if it serves “in part to punish,” and United States v. Bajakajian, 524 U. S. 321 (1998), for the punitive-exaction framing. It then resolves the claim by pointing to a lack of historical or precedential support for treating a fairly conducted tax sale (returning only surplus proceeds) as an excessive fine.

3.2 Legal Reasoning

(a) The Court’s rule: auction price is the baseline (with a fairness condition)

The central doctrinal move is definitional: in tax sales, the Constitution requires return of the surplus above the tax debt, but it does not require the government to ensure that the owner receives what the property might have fetched in a non-forced, “at leisure” market sale. Thus, the auction price becomes the relevant constitutional benchmark for measuring the owner’s recoverable interest—provided the sale is “fairly conducted in light of our country’s history of tax sales.”

(b) Why fair market value is rejected in this context

  • Text and tradition: The Court reads history as establishing a stable “surplus proceeds” model, not a “fair market value” model.
  • Context sensitivity of “just compensation”: Even in eminent domain, market value is not the only constitutionally acceptable measure (United States v. 564.54 Acres of Monroe and Pike County Land).
  • Avoidability rationale: The Court emphasizes that owners generally can avoid tax sales by paying, refinancing, borrowing, or selling prior to foreclosure—making the traditional surplus-only regime “just” in the Court’s view.
  • Administrability and systemic consequences: Requiring governments to “top up” to fair market value would, in the Court’s telling, either (i) force governments into the real-estate-sales business (holding property, marketing it, bearing vacancy risk) or (ii) produce frequent net losses where auction prices are below appraised values—potentially collapsing tax-sale systems as a debt-collection mechanism.

(c) The “fairly conducted” limitation—and what the Court does not decide

The Court deliberately avoids specifying the “contours” of what makes an auction “fairly conducted,” and it declines to reach Pung’s claims that Isabella County’s procedures were unfair (e.g., selling the home rather than pursuing other collection tools, or alleged bailee duties). The opinion leaves open that “blatantly unfair procedures” (e.g., a sham sale or strategic delay through market collapse) might implicate constitutional limits, but it sends the case back for preservation and development of those arguments.

JUSTICE SOTOMAYOR’s concurrence underscores that point: she reads the majority as not endorsing any party’s proposed articulation of the fairness standard and as leaving those questions for remand.

(d) Eighth Amendment: why the “fair market value” theory fails

On the Excessive Fines Clause, the Court takes a historically anchored approach similar to Austin v. United States: the dispositive defect is the absence of historical evidence or precedent treating a fairly conducted tax sale (with return of surplus proceeds) as a punitive “fine” requiring further payment. The Court also stresses that adopting Pung’s Eighth Amendment theory would replicate the same practical disruption it identified under the Takings Clause.

Notably, the Court declines to decide broader doctrinal questions raised by the County and the United States: whether the Fifth and Eighth Amendments can both apply to the same action, and whether the Excessive Fines Clause is limited to crime-connected fines.

3.3 Impact

(a) A new ceiling on Tyler-based recovery theories

After Tyler, many challenges targeted governmental retention of value in tax foreclosures. Pung draws a firm line: Tyler guarantees surplus proceeds, not fair market value. Litigants seeking “full value” compensation must pivot away from valuation theory and toward process theory—arguing that the sale was not “fairly conducted” (or that the government exceeded historical authority in the manner of collection).

(b) Litigation shifts to “fairness of the tax sale”

Because the Court reserves the fairness inquiry, the next wave of cases is likely to focus on:

  • Whether notice and redemption opportunities were adequate in practice, not just in form.
  • Whether auction mechanisms were structured to depress price (or constitute a “sham sale”).
  • Whether delays, fees, bundling practices, or bidder restrictions materially undermined competitiveness.
  • Whether the government’s chosen enforcement steps are consistent with “our country’s history of tax sales” (the Court’s phrasing), a standard that may invite deeper historical analogies and record development.

(c) Government operations: preservation of traditional tax-sale systems

For state and local governments, the decision is a strong validation of traditional foreclosure-and-auction collection models—so long as they remain within historically recognizable boundaries. The Court’s policy discussion (administrative feasibility, risk allocation, and potential revenue impacts) signals an institutional reluctance to constitutionalize an approach that would routinely require governments to pay delinquent taxpayers out of general revenues because an auction cleared below appraised value.

(d) The Thomas concurrence as a roadmap for future procedural challenges

JUSTICE THOMAS agrees that surplus proceeds can be just compensation when consistent with historical practice, but he describes facts suggesting potential illegality or unfairness (including disputed notice, disputed validity of the tax, and the large gap between assessed value and auction price). His opinion sketches historically “strict limits” on tax enforcement—such as exhausting personal property first, selling only so much land as necessary, and punctilious compliance—implying that if a plaintiff can show departure from those limits, the “auction price” baseline may not control. Even where not binding, this concurrence may shape how litigants frame “unfairness” on remand and in future cases.

4) Complex Concepts Simplified

  • Takings Clause / “just compensation”: When the government takes private property for public use, it must pay “just compensation.” In this case, the dispute is not whether compensation is owed (surplus is owed under Tyler), but how to measure what is “just” after a tax sale.
  • Fair market value: The price a willing buyer would pay a willing seller in an ordinary, non-forced sale. The Court says tax auctions are structurally different and need not be measured by this hypothetical benchmark.
  • Surplus proceeds (overplus): The money left after the tax debt (and lawful costs) is paid from the sale proceeds. Pung treats return of surplus as the constitutionally required measure in a fair tax sale.
  • “Fairly conducted” tax sale: A sale consistent with the Nation’s historical and traditional tax-sale practices. The Court does not define the full test; it flags that extreme unfairness (sham sales, strategic delays) could matter.
  • Excessive Fines Clause: The Eighth Amendment limits punitive economic sanctions. Pung argued the shortfall from fair market value is an “excessive fine”; the Court rejects that absent historical support and because the mechanism is framed as tax collection, not punishment, when fairly conducted.

5) Conclusion

Pung v. Isabella County establishes a clear rule with a significant qualifier: in tax foreclosure sales, the auction sale price—paired with return of surplus proceeds—is the constitutional baseline for “just compensation,” not hypothetical fair market value, so long as the tax sale is fairly conducted in light of historical practice. The Court also refuses to use the Eighth Amendment to impose a fair-market-value payout obligation.

The decision narrows the post-Tyler landscape by foreclosing “fair market value” as a general constitutional entitlement in tax-sale settings, while simultaneously opening (and redirecting) the main battlefield to whether the government’s procedures were historically and constitutionally “fair”—an issue the Court intentionally leaves for further litigation on remand.
