Keogh "filed-price doctrine"

The Supreme Court articulated the Keogh "filed-rate doctrine" in the case of Keogh v. Chicago & N. W. R. CO., 260 U.S. 156 (1922). The filed-rate doctrine generally forbids the recovery of treble damages under the Sherman Act based on the payment of rates that are established by regulated tariffs, even if the defendants engaged in illegal price-fixing.
