Pung v. Isabella County: Why SCOTUS Just Put Tax‑Sale Auctions Under the Microscope

The June 23, 2026 ruling in Pung v. Isabella County doesn’t kill tax sales — it turns auction design into a constitutional variable for every jurisdiction in the country. 🔍

----------------------------------------------------------------------------

1. The case that picked up where Tyler left off 🧩

On June 23, 2026, the U.S. Supreme Court decided Pung v. Isabella County, Michigan (No. 25‑95), one of the most important tax‑foreclosure decisions since Tyler v. Hennepin County in 2023.

A Michigan family owed about $2,242 in property taxes on a home the county itself had appraised at $194,400. 🏠💸 The county foreclosed, sold the home at a tax auction for $76,008, and the buyer later flipped it for $195,000.

After returning $73,766 in surplus, the county argued that was all the Constitution required. The owners argued “just compensation” should track fair market value, not a distressed auction price.

2. What SCOTUS actually decided ⚖️

The Court took a middle path. It vacated and remanded the lower court’s decision instead of declaring that tax foreclosures must always pay full fair market value.

At the same time, it refused to bless any low auction price as automatically constitutional. ❌

Instead, the justices adopted a process‑fairness test:

• Just compensation now depends on how the auction was run — was it public, competitive, and reasonably structured?
• Rules like cash‑only bidding, bans on pre‑sale inspections, limited marketing, and very short bidding windows can all count against a jurisdiction if they predictably depress prices. 💳🚫🔎📉

In plain English: auction architecture is now part of the constitutional analysis.

The Court largely sidestepped the separate Excessive Fines question, leaving room for future cases where the gap between the tax debt and lost equity is even more extreme. 🚨

3. Why this matters for each side of the table 🏚️🏦🏛️

• Homeowners and their lawyers 🏚️⚖️

Pung preserves the basic tax‑sale system but opens a new process‑based path to challenge bad outcomes. Owners and their counsel don’t have to prove outright fraud; they can point to structural choices that suppress competition and argue those choices fail the process‑fairness test.

• Tax lien investors and funds 🏦📊

For roughly two decades, local governments “owned” the auction rules and investors focused on yield. Now those worlds overlap.

Jurisdictions that insist on cash‑only, no‑inspection, under‑marketed auctions aren’t just operationally inefficient — they may be § 1983 class‑action targets, with investors’ deals pulled into the litigation record. ⚠️

• Local governments and collectors 🏛️📑

Tax sales survive Pung, but the risk profile changes.

Counties that modernize toward transparent, well‑advertised, multi‑channel auctions with realistic settlement terms will be in the strongest position. ✅ Those that don’t will be asked, in court, to explain why bidders were boxed out and prices predictably depressed. ❓

4. How to evaluate a tax‑sale auction after Pung ✅📋

In the full JurisDeed guide, we break the new process‑fairness standard into five practical categories and provide a Process Fairness Audit Checklist you can run against any jurisdiction:

• 📢 Advertising & notice – Are properties marketed beyond the legal‑notice page, and for long enough that bidders can do real diligence?
• 🎯 Bidding access & competition – Are online and absentee bidding allowed, or do local rules shrink the bidder pool without a solid justification?
• 🧾 Property access & information – Can bidders at least see the exterior and basic records, or are they flying blind?
• 💳 Payment & settlement – Is there a reasonable closing window and more than one payment method, or is the sale structured only for insiders with cash in hand?
• 📬 Surplus and post‑sale rights – Are surplus proceeds automatically calculated and returned, with clear notice to the former owner, as Tyler requires?

Unchecked boxes on that checklist map directly to litigation exposure — from moderate to critical risk. 🔴

5. What comes next — and where to go deeper 📈

Pung is not the last word on tax foreclosure. It’s the opening move in a long run of process‑fairness litigation and statutory clean‑up that’s coming next. ⚖️📚 As lower courts start applying this standard — and as states scramble to modernize their auction rules — the real story will be how different jurisdictions respond. 🏛️🗺️

That’s the part we’ll be tracking. As new decisions land, as legislatures revise tax‑sale statutes, and as best‑practice auction architectures emerge, we’ll be breaking those changes down through the same lens: what actually shifts risk for homeowners, investors, and local governments, and what is just noise. 🏚️🏦🏛️📊
