Key legal question
Whether the Lugano Convention's exclusive jurisdiction rule for leases of immovable property applied to the hangar dispute.
Extracted holding
Yes. The hangar lease fell within Art. 16(1)(a) LugÜ, so only the courts of the state where the property is situated had jurisdiction.
Extracted reasoning
The dispute concerned a lease of an immovable property. The fact that the parties were Swiss residents and that only rent was claimed did not remove the case from Art. 16 LugÜ. The purpose of the rule is to align forum and applicable special tenancy law; no teleological reduction was justified.
