Questão jurídica principal
Whether the federal criminal appeal against the preventive seizure was admissible despite its incidental nature.
Decisão extraída
The appeal was admissible because the seizure could cause an irreparable legal prejudice to the accused.
Fundamentação extraída
A seizure securing costs is an incidental decision, but it is challengeable when it may deprive the accused of free disposal over property and affect ownership rights in a way that a later favorable decision could not repair.
