Abstract

The 1980 Vienna Convention on Contracts for the International Sale of Goods (CISG) is currently the law of ninety-seven countries around the world. Part II (Formation of the Contracts) deals with the conclusion of the contract by way of the meeting of minds through offer and acceptance. CISG has been able to adapt to modern electronic means of communication such as email, despite the fact that the means of communication mentioned in the CISG are the ancient telegram and telex.
When dealing with the electronic contract of sale, we are referring to those in which the offer and acceptance are made by electronic means, as derived from the rules of the offer and the acceptance under the CISG.
In short, we are thinking about computers—today also mobile phones—connected to a network (internet). From this perspective, every purchase and sale contract under the CISG is capable of being concluded by electronic means following the classic and universal parameter (we find it in all legal systems in the world) of consent through the two declarations of will that give life to the contract, the offer and the acceptance. The offer and acceptance as a mechanism well present in the life of the contract and not only in its formation since other issues such as its modification or termination are observed under those parameters.
The Vienna Convention has demonstrated its flexibility by adapting and applying without problems to electronic contracting. Technologies are evolving rapidly and we no longer question the validity of contracts concluded through electronic means but new and interesting perspectives emerge, as well as various legal problems that can be associated with the era of the digital economy, from the use of platforms as an intermediary in the contracting of goods or services—or simply as a meeting place or recreational or social exchange—when not as part of the commercial contracts themselves, the use of computer programs in the formation and performance of the contract, legal transactions on data, or the use of artificial intelligence in contracting.
From a legal perspective, the question is whether the CISG, which is a traditional instrument of contract law, is sufficient to respond to the problems posed by the digital economy, specifically in the rise of the so-called SmartCcontracts, and the use of Artificial Intelligence (AI) in the formation of the contract.
