26.Italy also resorted to rebus sic stantibus after the First World War, through transitional legislation, which allowed the use of force majeure to cases, which the war had made performance extremely onerous to one party. Even after that, Italian courts applied rebus sic stantibus, either by accepting it as a general principle of law or by extending the concept of force majeure so as to include contracts that had become notably onerous because of unforeseen events. However, the highest courts (Cortes di Cassazione) of Florence, Rome and Turin resolutely rejected rebus sic stantibus soon after. [12]
