A Legal Theory of Platform Law

This paper discusses the recently emerging platform law from a jurisprudential point of view. After defining the platform as a general coordination mechanism, it deals with topics such as the rationale for regulation, its main goals, and its general characteristics. According to the study, the main argument for regulation is that the platform, as a coordination mechanism, tends to become unstable without intervention, or to become harmful from the point of view of society. Above all, it tends to abuse the asymmetric power situation that exists between the platform and its users. These conditions must be prevented from occurring, and platform users must be protected in certain situations. The study lists four features that characterise platform law: its ex ante regulatory nature, the predominance of technology regulation and self-regulation, and the extensive use of user protection tools, such as complaint mechanisms, protection of user accounts, and explainability obligations. This toolbox partly resembles the long-established methods of consumer protection, but it also differs from it in certain ways.
