Questione giuridica chiave
Whether the cantonal court arbitrarily found that the buyer had requested a two- to three-month delay in implementation.
Decisione estratta
No arbitrariness was shown; the buyer itself acknowledged granting additional time, and the court had not ignored the relevant letter.
Motivazione estratta
The challenged finding was supported by the record, including the buyer's own correspondence. Any argument about allocation of fault under federal contract law was inadmissible in public-law review.
