Londoner v. City and County of Denver

Denver's city charter authorized local improvements with costs assessed against specifically benefited properties, and required due notice and a hearing opportunity before any such assessment; Mr. Londoner and other property owners (plaintiffs) sued in state court to challenge a street-paving assessment on their abutting properties, and the trial court granted relief, specifically finding the city had given them no opportunity for a hearing before assessing the cost. The state supreme court reversed on the merits without disturbing that factual finding about the lack of a hearing opportunity, and Londoner sought U.S. Supreme Court review.
