Questão jurídica principal
Whether the appeal against the provisional maintenance order is admissible under Art. 93 LTF
Decisão extraída
The order is an incidental decision; the appeal is only admissible if irreparable harm is shown.
Fundamentação extraída
The provisional support order under former Art. 283 aCC is an advance enforcement measure, not a mere regulatory measure. Because no separate jurisdictional ruling was notified, Art. 92 LTF does not apply.
