Questão jurídica principal
Whether the appellant, as a third-party claimant, had standing to appeal the attachment execution decision
Decisão extraída
A third-party claimant has no legally protected interest to challenge defects in the execution of the attachment itself; ownership claims must be pursued in the opposition procedure.
Fundamentação extraída
Under Art. 76 BGG, a civil appeal requires a legally protected interest. The appellant asserted only ownership of the seized motorcycle and complained about the manner of execution. Such objections do not confer standing; the proper remedy is the third-party opposition procedure under Art. 106 ff. SchKG.
