Terry v. Tyson Farms, Inc.

(1) Whether an injury to competition must be pleaded and proved to establish liability for violation of § 192(a) and (b) of the Packers and Stockyards Act; and (2) whether, assuming that § 192 is ambiguous, the courts should have deferred, under Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc., to Department of Agriculture decisions holding that § 192(a) and (b) does not require a showing of injury to competition.
