Londoner v. City and County of Denver
The Supreme Court ruled that Denver violated the due process rights of landowners when it assessed them for a street-paving project after only letting them submit written complaints, without ever giving them a real chance to argue their case or offer proof.
The decision establishes that when a government body decides how much an individual property owner owes based on facts specific to that owner, due process requires an actual opportunity to be heard—not just the right to file paperwork that no one reviews or responds to.
“a hearing in its very essence demands that he who is entitled to it shall have the right to support his allegations by argument however brief, and, if need be, by proof, however informal”
The Court's core statement of what due process requires beyond simply accepting written objections.
How it got here: A Colorado trial court sided with the landowners; the Colorado Supreme Court reversed and ordered judgment for the city; the landowners brought the case to the Supreme Court by writ of error.
The Case in Depth
What happened
Landowners in Denver's Eighth Avenue Paving District were assessed for the cost of paving a street next to their property. They believed the assessment was improperly calculated and far exceeded any benefit the paving gave their land, and they filed written objections with the city as the charter allowed. The city council never held a hearing on those objections before finalizing the assessment.
The question before the Court
When a city assessed landowners for the cost of paving a street, did letting them file written objections—without ever actually hearing them—satisfy the Constitution's due process guarantee?
Why it matters
Property owners facing government assessments—for paving, sewers, or similar local improvements—are entitled to more than a chance to mail in a written complaint. Cities and other local governments administering special assessments must build in an actual hearing, with a chance to make arguments and present evidence, before the charge becomes final and enforceable.
What changes now
The judgment of the Colorado Supreme Court is reversed, meaning the landowners are entitled to a decree freeing their land from the tax lien created by the void assessment. The Court did not need to reach the landowners' separate argument that their corner lots were assessed for more than their value. Colorado and its cities would need to build an actual hearing process into similar assessment procedures going forward.
What this does not decide
The Court did not decide whether the underlying paving statute itself was unconstitutional, nor whether the city council could validly decide without notice that a proper petition for the work had been filed — it upheld that separate step. It also left aside whether the corner-lot assessments were excessive in amount.
Concurrences and dissents
Dissent — Justice Fuller
The Chief Justice, joined by Justice Holmes, dissented from the Court's judgment. The opinion does not include any explanation of their reasoning beyond the notation that they dissented.
How the Court got there
The legal reasoning, step by step
- The Court distinguished two different government functions under the city charter: first, the decision to order the paving work at all (a legislative-type decision that could be made conclusively by the city council without individualized notice), and second, the assessment of costs against specific landowners (a decision that turns on facts particular to each owner).
- For the initial decision to authorize the work, the Court held that the charter could validly let the city council determine conclusively, without notice to landowners, whether a proper petition had been filed, because no assessment or property right was yet at stake at that stage.
- For the assessment of costs on specific lots, the Court applied the settled due process rule that when a legislature delegates to a subordinate body the job of deciding whether, how much, and on whom a tax will fall, the person taxed must get notice and a chance to be heard before the tax becomes final.
- The Court held that merely allowing landowners to file written objections, with no one ever reviewing or responding to them in any hearing, does not satisfy that requirement — a real hearing means the right to support one's claims with argument and, if needed, informal proof.
- Because the city council adopted a resolution confirming the assessment without holding any hearing on the landowners' filed objections, the Court concluded the assessment process failed to give them the process the Constitution demands.
- The Court therefore held the assessment as applied was void for lack of due process, regardless of whether the underlying paving statute itself was constitutionally sound.
