Key legal question
Whether the refusal to take evidence on the wife's working rate violated the right to proof / hearing.
Extracted holding
No violation: the offered evidence was rejected after anticipatory assessment because it could not alter the outcome; in any event, the wife's current salary was irrelevant.
Extracted reasoning
A party has a right to relevant evidence, but the court may refuse proof that is manifestly unsuitable or immaterial. Here the contested fact could not affect the legally decisive criterion.
