Questão jurídica principal
Whether the Federal Supreme Court could hear the ESTV's appeal against the remand decision
Decisão extraída
The remand decision was an interlocutory decision and did not cause irreparable harm or justify immediate review; the appeal was therefore not admissible.
Fundamentação extraída
The lower court still required the ESTV to re-examine the case and decide anew. No purely mechanical implementation remained, and the required clarification would not necessarily lead to a lower assessment. Neither Art. 93(1)(a) nor Art. 93(1)(b) BGG was satisfied.
