Key legal question
Whether the wife's withdrawal of her maintenance claim amounted to an irrevocable waiver under cantonal procedure
Extracted holding
The withdrawal was interpreted as a waiver communicated to the husband and could not be revoked once communicated.
Extracted reasoning
If an express statement that one wants no pension already constitutes a binding waiver once communicated, then a communicated cancellation of a pension claim can likewise be treated as a waiver; this interpretation was not arbitrary.
