Kernrechtsfrage
Whether the husband's deteriorated health and reduced earning capacity justified modifying the divorce maintenance obligation
Extrahierter Entscheid
The husband did not prove a sufficiently important, durable and unforeseeable worsening of his economic situation.
Extrahierte Begründung
The cantonal findings that his future invalidity benefits would roughly replace his former income were binding; the resulting economic change did not show the required durable deterioration under former divorce law.
