Questão jurídica principal
Whether the appeal against the interlocutory MLAT decision was admissible because of immediate and irreparable harm
Decisão extraída

Fundamentação extraída
Interlocutory MLAT decisions are appealable only for issues causing such prejudice; broader objections must be reserved for the final closing decision.
