We live in a time when concerns about influence over the American political process by powerful private interests have reached an apogee, both on the left and the right. Among the laws originally intended to fight excessive private influence over republican institutions were the antitrust laws, whose sponsors were concerned not just with monopoly, but also its influence over legislatures and politicians. While no one would claim that the antitrust laws were meant to be comprehensive anti-corruption laws, there can be little question that they were passed with concerns about the political influence of powerful firms and industry cartels.

Since the 1960s, however, antitrust law’s scrutiny of corrupt and deceptive political practices has been sharply limited by the Noerr-Pennington doctrine, which provides immunity to antitrust liability for conduct that can be described as political or legal advocacy. The doctrine was created through apparent First Amendment avoidance, based on the premise that the Sherman Act could not have been intended to interfere with a right to petition government.

The Noerr decision, dating from 1961, was strained when it was decided and has not aged well. As an interpretation of the antitrust laws, it ignored Congressional concern with political mischief undertaken by conspiracy or monopoly. Its legitimacy has always rested on avoidance of the First Amendment, and while Noerr itself may have legitimately reflected such avoidance, the subsequent growth of a Noerr immunity has blown past any First Amendment-driven defense of its existence. For that reason, others have suggested a reformulation of the doctrine. The better answer is that, lacking constitutional or statutory foundation, Noerr should be overruled.

The First Amendment guarantees freedom of speech, assembly, and “to petition the government for a redress of grievances.” It therefore protects efforts to influence political debate as well as legitimate petitioning in the legislative, judicial or administrative processes. The First Amendment does not, however create a right to bribe government officials, deceive agencies, file false statements, or abuse government process through repeated filings designed only to injure a competitor. Nonetheless, each of these activities has, in some courts at least, been granted immunity under the overgrown Noerr immunity. It is an extra-constitutional outlier ripe for reexamination.

Overruling Noerr would not make political petitioning illegal. It would, instead, require defendants to rely on the First Amendment when seeking to defend what would otherwise be conduct that is illegal under the antitrust laws. Doctrinally, this is to force courts to address whether conduct in question is actually an antitrust violation, and if, so whether it is protected by the First Amendment or not, drawing on an established jurisprudence for some of the problems presented in the Noerr context.
