Key legal question
Whether the tax mortgage had lapsed because of procedural defects in collection and enforcement.
Extracted holding
No lapse: the authority could rely on the enforcement office's information, the owner had no right to be included in the collection proceedings, and the challenged conduct did not breach good faith or hearing rights.
Extracted reasoning
The enforcement office knew the debtor and had investigated his assets; its assessment was reliable. The owner had no claim to participate unless she paid the tax and became subrogated. The later collection delay was attributable to pending remedies by the debtor.
