The subject of this paper is related to the contract of adhesion. The author questions the contractual aspect of this type of “contract,” and proposes a theoretical construct in line with private civil law. According to this proposition, the contract of adhesion would be a hybrid legal act which would include a contractual part and an imposed terms and conditions part (clause à contenu imposé). This paradigm shift aims to facilitate better public protection with regards to the imposed terms and conditions. More broadly, this paper looks into the contemporary definition of “contract” and the way we define our private civil law concepts.
