In the competition for customers, things can and may get tough at times. But the limits of fair competition should be respected. Competition law, and in particular so-called fair trading law, is concerned with the rules of fair commercial conduct. The respective competitors and consumers are protected. The goal is undistorted competition.
The boundaries to unfair competition are often difficult to determine in individual cases and require close examination and design.
Antitrust law also protects competition in the form of the structure of the applicable economic order. It is designed to prevent monopolies and agreements that restrict competition.
