In 2012, New Orleans officials detect code violations at city-owned property. Yikes! They commence enforcement action against a former owner (from whom they’d seized the house in 1998 over unpaid taxes). In 2015, officials sell the house to couple without mentioning the still-ongoing code enforcement proceedings. By happenstance, the couple catches wind, persuade officials to cancel the lien against the house. Yikes! Without warning, the city demolishes the house. The couple complains; officials send them an $11k bill for the demo. Fifth Circuit: Could be the couple have some colorable Fourth, Fifth, and Fourteenth Amendment claims.
