Rule of reason

Definition

The rule of reason is a legal doctrine used in antitrust law that assesses whether a business practice promotes or suppresses market competition. It determines the legality of certain business behaviors based on their actual effects on competition, rather than categorizing them as inherently lawful or unlawful. This approach allows for a nuanced evaluation of practices like price-fixing or mergers, considering the context and circumstances in which they occur.
