Questão jurídica principal
Whether the appeal against the custody allocation was admissible and whether the federal court could review only constitutional violations
Decisão extraída
In marital protection matters, only constitutional violations can be raised; the appeal was admissible only insofar as it challenged custody allocation.
Fundamentação extraída
Such decisions are provisional measures under Art. 98 BGG, so review is limited to constitutional rights, with stringent reasoning requirements.
