Question juridique clé
Whether the appeal was admissible regarding the CHF 35,000 already awarded by the lower court and the related interest claim.
Solution extraite
The appellant lacked legal interest to challenge the award in his favor, and he did not sufficiently challenge the rejection of interest.
Motifs extraits
A party cannot seek reversal of a portion of the judgment that is favorable to it without being aggrieved; a separate, reasoned challenge is required for the interest issue.
