Key legal question
Whether the Federal Court could review the wife's factual assertions and the appellate court's findings on need and savings.
Extracted holding
Challenges to factual findings were inadmissible because they were not subject to final cantonal review; only questions of federal law could be freely reviewed.
Extracted reasoning
Under the Zurich Nichtigkeitsbeschwerde system, alleged arbitrary fact-finding was not a final cantonal decision; federal review was therefore barred for those points.
