Questão jurídica principal
Whether the auction notice could still be challenged in the cost-invoice appeal after the earlier appeal on the auction notice became moot
Decisão extraída
Because the prior appeal was struck off as moot and no merits decision was rendered, the auction notice was generally binding in the enforcement proceedings, subject only to review for nullity.
Fundamentação extraída
A decision ending a complaint as moot does not decide the merits and gives the underlying order limited material finality. Only nullity under Art. 22 SchKG may still be raised at any time.
