Key legal question
Whether the federal appeal sufficiently challenged the cantonal court's refusal to decide on domicile in A.
Extracted holding
No. The appellants failed to explain why the cantonal court should have been required to enter into the matter, so the complaint did not meet the federal reasoning requirements.
Extracted reasoning
The filing contained no specific criticism of the cantonal court's finding of lack of subject-matter jurisdiction and therefore did not satisfy Art. 42(2) and Art. 106(2) BGG.
