Key legal question
Whether the federal appeal against the cantonal provisional-measures decision was sufficiently reasoned under Art. 106(2) LTF
Extracted holding
No. The appellants failed to demonstrate arbitrariness in the cantonal court's finding that they had not made a likely showing of infringement of their reserved shares.
Extracted reasoning
In a case reviewable only for constitutional violations, the appellants had to identify and substantiate arbitrary reasoning. They merely opposed their view to the cantonal court's without proving how the assessment of estate value and reserved shares was manifestly untenable.
