Noerr-Pennington Doctrine - Limited Scope

Limited Scope

The scope of Noerr-Pennington immunity, however, depends on the "source, context, and nature of the competitive restraint at issue." Allied Tube & Conduit Corp. v. Indian Head, Inc., 486 U.S. 492, 499, 100 L. Ed. 2d 497, 108 S. Ct. 1931 (1988).

• If the restraint directly results from private action there is no immunity. See id. at 500 (where the "restraint upon trade or monopolization is the result of valid governmental action, as opposed to private action," there is immunity). Passive government approval is insufficient. Private parties cannot immunize an anticompetitive agreement merely by subsequently requesting legislative approval.
• Private parties may be immunized against liability stemming from antitrust injuries flowing from valid petitioning. This includes two distinct types of actions.

1. A petitioner may be immune from the antitrust injuries which result from the petitioning itself. See Noerr, 365 U.S. at 143 (finding trucking industry plaintiffs' relationships with their customers and the public were hurt by the railroads' petitioning activities, yet the railroads were immune from liability).
2. Also, parties are immune from liability arising from the antitrust injuries caused by government action which results from the petitioning. See Pennington, 381 U.S. at 671 (holding plaintiffs could not recover damages resulting from the state's actions); Mass. Sch. of Law at Andover, Inc. v. Am. Bar Assoc., 107 F.3d 1026, 1037 (3d Cir. 1997) (holding Noerr gave immunity for any damages stemming from state adoption of requirements for bar admission to petitioners who lobbied for their adoption); 1 Areeda & Hovenkamp, supra, at P 202c. Therefore, if its conduct constitutes valid petitioning, the petitioner is immune from antitrust liability whether or not the injuries are caused by the act of petitioning or are caused by government action which results from the petitioning.
