Questão jurídica principal
Whether a negative declaratory action in an international case under the Lugano Convention requires a specific legal interest
Decisão extraída
Yes. The national requirement of a sufficient legal interest still applies; a mere desire to secure a favorable forum is not enough.
Fundamentação extraída
Art. 21 LugÜ governs lis pendens and does not preclude national procedural law from requiring a declaratory interest. The plaintiff’s wish to prevent the opponent’s later claim and choose the forum is not a protected interest.
