The Supreme Court ruled this morning that when a county seizes a home for unpaid property taxes, the "fair market value" under the Fifth Amendment is simply whatever the property fetches at auction—and nothing more. In *Pung v. Isabella County, Michigan*, the Court decided against the Pung family, who lost their $194,400 house after it was seized for a $2,241.93 tax bill and sold at auction for just $76,008. The decision means homeowners in similar situations are entitled only to surplus proceeds from the auction, not the home's actual market value, though the Court left open the question of whether the auction must be "fairly conducted" to meet constitutional standards.
The case centers on a dramatic sequence of events: Isabella County, Michigan retroactively reclassified the Pung family's home as a second residence for the years 2007 to 2011, creating an unpaid property tax bill of $2,241.93 in 2012. Three years later, in 2015, the county seized the house and sold it at what the National Taxpayers Union Foundation's Taxpayer Defense Center called a "sham auction" for $76,008. The auction winner immediately resold the property for $195,000, leaving the Pungs with a loss of $118,000 on a debt of roughly $2,200. The family sued, arguing this violated both the Takings Clause of the Fifth Amendment (which requires "just compensation" when property is taken for public use) and the Excessive Fines Clause of the Eighth Amendment (which prohibits disproportionate penalties).
In an opinion written by Justice Alito, the Supreme Court held that fair market value for Fifth Amendment purposes is the auction price, but only if the sale was fairly conducted. The Court didn't define what constitutes a "fair sale," instead directing the lower court to make that determination. Similarly, on the Eighth Amendment claim, the Court found that while property forfeiture can be a fine, there's no evidence that a fairly conducted tax sale is punitive. Justice Thomas, in a concurrence joined by Justice Gorsuch, described the "fundamental unfairness" of the county's actions and emphasized that the Pungs' fight isn't over—the lower courts should carefully scrutinize whether the auction proceedings met constitutional standards, and if they didn't, the county still violated the Takings Clause.
The ruling leaves a critical opening for future challenges but establishes a tough standard for homeowners. The Court's decision means that even when a property worth nearly $200,000 is seized over a $2,200 debt and sold for a fraction of its value, the constitutional question hinges entirely on auction procedures rather than the proportionality of the loss. The NTUF's Taxpayer Defense Center had argued in a supporting brief that losing $118,000 for a $2,241 tax bill is clearly disproportionate, but the majority didn't accept that framing. Justice Thomas noted that the county not only confiscated property for a tax the Pungs didn't originally owe, but also chose to seize real property "vastly more valuable than the miniscule assessment" rather than other, more proportionate assets.
The case now returns to the lower court to determine whether Isabella County's auction was conducted fairly. If the auction procedures didn't meet constitutional standards, Justice Thomas wrote, the Pungs' rights will still be vindicated. For thousands of Americans who lose homes to tax foreclosure auctions each year, the message is clear: the auction price is the ceiling on compensation, but the fairness of that auction is now the battleground where constitutional protections will be won or lost.
