Questão jurídica principal
Whether refusing to hear the former spouse violated the right to be heard and arbitrariness prohibitions.
Decisão extraída
The refusal was permissible because the requested testimony could not reasonably change the assessment already supported by the file.
Fundamentação extraída
The court accepted an anticipatory assessment of evidence: the written record already sufficiently established the relevant facts, and the later proposal to hear the ex-spouse was not decisive.
