Key legal question
Whether the office and restaurant contracts formed a single lease relationship making separate termination of the office invalid.
Extracted holding
The contracts were separate; separate termination of the office lease was permissible.
Extracted reasoning
Art. 253a(1) OR and the parties' actual intent required a sufficiently untrammelled unity. The court found no decisive unity of contracts and no proof that the office was a conditio sine qua non of the restaurant lease.
