Key legal question
Whether the 3 June 1991 agreement included compensation for granting the option/right of emption, allowing the seller to keep the instalments.
Extracted holding
No. The cantonal court's finding that the parties never agreed on any remuneration for the granted right of emption is binding.
Extracted reasoning
Interpretation was based on the parties' actual common intent; there was no agreement on a fee for the option right, so the confidence principle could not be invoked.
