Filed-Rate Doctrine Law and Legal Definition

Filed-Rate Doctrine is a common law rule which provides that any entity that is required to file tariffs governing the rates, terms, and conditions of service must adhere strictly to those terms. This principle forbids a regulated entity from charging a rate other than the one on file with the appropriate federal regulatory authority. For example, this general principle is codified in the Communications Act, which requires interstate communications common carriers to file tariffs and not to deviate from them. 47 USCS § 203 (a) (c).

Filed-Rate Doctrine is also known as filed tariff doctrine.
