Ordinarily, whether particular action violates section 1 is determined through case-by-case application of the rule of reason.
(Business Electronics Corp. v. Sharp Electronics (1988), 485 U.S. 717, 723, 99 L. Ed. 2d 808, 816, 108 S. Ct. 1515, 1519.) Certain categories of agreements, however, have been held to be
per se violations, thus dispensing with the need for case-by-case evaluation. The
per se rules are applicable only to conduct that is so anticompetitive that further examination of the challenged conduct is not necessary.
(Business Electronics, 485 U.S. at 723-24, 99 L. Ed. 2d at 816, 108 S. Ct. at 1519.) Since price discrimination has been held not to be a
per se violation of section 1
(Crowl Distributing Corp. v. Singer Co. (D. Kan. 1982), 543 E Supp. 1033, 1037), allegedly anticompetitive discriminatory pricing arrangements are examined under the rule of reason.
St. Bernard General Hospital, Inc. v. Hospital Services As
sociation of New Orleans, Inc. (5th Cir. 1983), 712 F.2d 978, 985; see also
Monahan’s Marine, Inc. v. Boston Whaler, Inc. (1st Cir. 1989), 866 F.2d 525 (where defendant sold boats to plaintiff’s competitors on better terms and at lower prices, court applied rule of reason to determine whether the anticompetitive effects of the agreements outweighed their legitimate business justifications);
Zoslaw v. MCA Distributing Corp. (9th Cir. 1982), 693 F.2d 870, 886 (since vertical agreements are not a
per se violation of section 1, court examined the arrangement to determine whether it was reasonable);
Travelers Insurance Co. v. Blue Cross of Western Pennsylvania (3d Cir. 1973), 481 F.2d 80 (where plaintiff alleged that Blue Cross had a dominant competitive position resulting from the discriminatory pricing arrangement contained in Blue Cross’ contract with area hospitals, the court examined the contract itself, as well as the setting in which it originated for unreasonable restraint-of-trade characteristics).
