Questão jurídica principal
Whether the constitutional appeal was admissible against the completed sale of the property.
Decisão extraída
The appeal was inadmissible because even a finding that the authorities acted unlawfully would not undo the executed private sale involving third parties; only an ordinary civil court can decide on the transaction's validity.
Fundamentação extraída
The challenged act concerned a bilateral private-law transaction already completed and transferred to a third party. A federal constitutional appeal cannot annul such a sale, and any judgment would lack practical effect; therefore the matter is moot.
