Questione giuridica chiave
Whether all pre-delivery payments under the aircraft sale contract were subject to the same legal regime as arrhes/penalty
Decisione estratta
The parties could, under the trust principle, reasonably understand all pre-delivery payments to be subject to the same regime.
Motivazione estratta
The draft purchase agreement predating the final contract treated all instalments identically; the final wording could not be read in isolation from that prior common understanding.
