ABSTRACT
The day-to-day operations of any business – aviation-related or otherwise – would simply not be possible without the law of contract. Contracts are fundamental to any commercial enterprise and their application is so widespread that people may enter into contractual arrangements without even knowing it. The development of contract law in the civil law system can be traced back to the fourth and fifth centuries BC, in the period when the Greeks and Romans came to rely on laws designed to deal with international transactions. This chapter explains notion of causa in detail. Acceptance in civil law systems is the element that provides evidence that the other party has agreed to the terms proposed and thus leads to the formation of a contract. In common law systems, the doctrine of frustration operates so as to relieve the parties of their duty to perform when performance has either become impossible or totally impracticable without fault on either side.
