Questão jurídica principal
Whether the possession-based ownership presumption under Art. 930(1) CC applied to the disputed artworks.
Decisão extraída
The presumption did not assist the appellant because the possession was considered equivocal and, in any event, the respondent had proven ownership.
Fundamentação extraída
The court held that possession must be unambiguous; where the acquisition or control of the items is open to several explanations, the presumption may fall away. Here the lower court's finding that possession was doubtful did not matter because ownership was established by proof.
