Rule of reason refers to a legal standard used to evaluate whether a franchisor’s practices unreasonably restrict competition, weighing both pro-competitive benefits and anti-competitive harms. It requires a case-by-case analysis rather than automatic illegality. In franchising, the rule of reason is often applied to assess territorial restrictions, pricing policies, and non-compete clauses.
Rule of reason in franchising describes the legal principle under antitrust law where a court or regulator analyzes the competitive effects of a franchisor’s practices to determine if they are lawful. Instead of declaring certain practices automatically illegal (as under a "per se" rule), the rule of reason looks at the practice’s purpose, the structure of the market, and the actual impact on competition. In franchising, courts apply the rule of reason when evaluating common system controls such as exclusive territories, supply mandates, or restrictions on franchisees’ outside activities. If the franchisor’s conduct is found to promote healthy competition or legitimate brand protection, it is generally upheld. The rule of reason provides flexibility and recognizes that some restrictions can be necessary for the successful operation of a franchise system.
Additional Definition: Under federal antitrust law, a method for judging illegality. Under the laws, certain practices are presumed to be illegal “per se” without regard to the precise harm they have caused or the business justification for their use. Other practices are judged under the 'Rule of Reason',under which the practices are generally deemed illegal only if, on balance, they harm competition. Also see “Antitrust Law.”

The concept of the rule of reason was first introduced by the U.S. Supreme Court in the 1911 case Standard Oil Co. v. United States. As franchising expanded in the mid-20th century, courts recognized that franchise systems needed a level of uniformity and control to succeed, and not all restrictions harmed competition. By the 1970s and 1980s, the rule of reason became the dominant approach to evaluating franchise practices under antitrust laws. Today, franchisors routinely design their agreements and policies with the rule of reason in mind to ensure that system-wide controls are legally defensible and appropriately balanced.
Rule of reason is a critical legal standard in franchising that balances competitive concerns with legitimate system needs. It ensures that franchise practices are not automatically condemned but are fairly assessed for their actual market impact. Understanding the rule of reason helps franchisors design legally compliant systems and helps franchisees recognize when restrictions may be fair business practices rather than antitrust violations.
