Key legal question
When does partial res judicata arise for a first-instance divorce judgment that is only partly appealed?
Extracted holding
The question is governed by cantonal procedural law. Under the revised Lucerne practice, the mere declaration of appeal suspends finality for the entire judgment at first, but the unchallenged part becomes final once the specific appeal and cross-appeal requests are filed with the appellate court, at the latest upon expiry of the cross-appeal declaration period.
Extracted reasoning
The court departed from its former practice of treating the entire divorce judgment as stayed in finality even when only ancillary points were appealed. It aligned Lucerne practice with other cantons and with federal appeal procedure, which distinguishes between the notice of appeal and the subsequent concrete appellate requests.
