Questão jurídica principal
Whether a psychological expert opinion on the child had to be ordered before deciding custody
Decisão extraída
The court held that no further psychological expert opinion was necessary because the facts were sufficiently clarified and the authority could rely on the existing record.
Fundamentação extraída
In child matters the court investigates ex officio, but it may reject evidence requests if it already has a sufficient basis for a proper child-welfare decision; the lower court's assessment was not arbitrary.
