Kernrechtsfrage
Whether the cantonal court properly established the content of Brazilian law under Art. 16 LDIP
Extrahierter Entscheid
The cantonal court did not establish foreign law ex officio and instead relied on the parties' concordant interpretation.
Extrahierte Begründung
Art. 16 LDIP requires the judge to determine foreign law on his own initiative, with party cooperation as a supplement only. The judge is not bound by the parties' legal characterization and may apply Swiss law only if foreign law cannot reliably be established.
