Key legal question
Whether the Swiss court had to stay the divorce case because a Brazilian proceeding was first pending under Art. 9 IPRG
Extracted holding
No stay was required because the Brazilian judicial-separation proceeding did not have the same subject matter as the Swiss divorce action.
Extracted reasoning
Art. 9 IPRG requires identity of parties and subject matter. A judicial separation and a divorce are distinct under Brazilian law; the Brazilian case concerned separation, not divorce, so there was no lis pendens conflict.
