Abstract
The chapter looks at the protection of ecnomic competition (antitrust) from the perspective of the traditional division of law into public and private. Its point of departure is the assertion that competition law has, since its birth hovered the limits and principles of public and private law.
On examples from the current competition regulation the chapter demonstrates that this tension between protection of public and at the same time private interests is still present in the contemporary antitrust of the EU and Czechia.
