Kernrechtsfrage
Whether the appeal raised a new and therefore inadmissible argument that the husband must support child B. under art. 159(3) CC
Extrahierter Entscheid
The argument was raised for the first time before the Federal Supreme Court and was therefore inadmissible.
Extrahierte Begründung
The wife had not invoked this federal-law argument in the cantonal proceedings; only the prematurity of removing the child-related pension share was argued below.
