Over the past three decades, anti-SLAPP statutes have become a familiar part of the litigator\u2019s toolkit.  When a lawsuit targets speech or petitioning activity, many lawyers instinctively reach for statutory anti-SLAPP protections and the procedural advantages they provide.  In the process, however, an older, and often broader, defense has been pushed into the background: the Noerr-Pennington<\/em> doctrine.<\/p>\n\n\n\n

Noerr-Pennington<\/em> remains one of the most effective civil defenses when faced with a claim arising from a party\u2019s petitioning activity.  Unlike many anti-SLAPP statutes, application of the doctrine does not hinge on whether the petitioning activity involves a matter of public concern.  And to overcome application of the Noerr-Pennington<\/em> doctrine, a plaintiff must prove that a defendant\u2019s petitioning activity was both objectively and <\/em>subjectively baseless. <\/p>\n\n\n\n

In an era when courts frequently wrestle with the scope of anti-SLAPP statutes, the Noerr-Pennington<\/em> doctrine continues to provide broad constitutional protection for genuine efforts to influence governmental action, even when the dispute is entirely private. <\/p>\n\n\n\n

Constitutional Origins<\/strong><\/h2>\n\n\n\n

The Noerr-Pennington<\/em> doctrine traces its roots to two Supreme Court decisions: Eastern Railroad Presidents Conference v. Noerr Motor Freight, Inc.<\/em>, 365 U.S. 127 (1961), and United Mine Workers of America v. Pennington<\/em>, 381 U.S. 657 (1965).<\/p>\n\n\n\n

In Noerr<\/em>, the Supreme Court held that railroads could not be subjected to antitrust liability for lobbying government officials to adopt legislation that would disadvantage competitors.[1]<\/a>  The Court reasoned that Congress could not have intended the Sherman Act to punish citizens for exercising their constitutional right to petition government.[2]<\/a>  Pennington<\/em> reaffirmed and expanded that principle,[3]<\/a> and California Motor Transport Co. v. Trucking Unlimited<\/em>, 404 U.S. 508, 515 (1972), later extended the doctrine beyond legislative lobbying to administrative proceedings and litigation itself.<\/p>\n\n\n\n

Although born in the antitrust context, the doctrine rests on broader constitutional principles.  As the Supreme Court has explained, the rights \u201cto assemble peaceably and to petition for a redress of grievances are among the most precious of the liberties safeguarded by the Bill of Rights.\u201d[4]<\/a>  Because of those constitutional foundations, courts have extended the Noerr-Pennington<\/em> doctrine far beyond antitrust claims. <\/p>\n\n\n\n

Rhode Island courts have embraced that view.  For example, in Hometown Properties, Inc. v. Fleming<\/em>, 680 A.2d 56, 60 (R.I. 1996), the Rhode Island Supreme Court observed that Noerr-Pennington<\/em> \u201ctakes precedence over common-law tort doctrines\u201d and statutory causes of action.  Likewise, in Pound Hill Corp. v. Perl<\/em>, 668 A.2d 1260, 1264 (R.I. 1996), the court recognized the doctrine\u2019s First Amendment roots and its role in protecting petitioning activity, but only when such petitioning is not a \u201csham.\u201d <\/p>\n\n\n\n

The Sham Exception<\/strong><\/h2>\n\n\n\n

The limiting principle of the Noerr-Pennington <\/em>doctrine is the so-called \u201csham exception\u201d established by the Supreme Court in Professional Real Estate Investors, Inc. v. Columbia Pictures Industries, Inc.<\/em>, 508 U.S. 49 (1993).  In accordance with the exception, petitioning activity in the form of litigation loses First Amendment protection only if it is both objectively and subjectively baseless.  Litigation is objectively baseless if \u201cno reasonable litigant could realistically expect success on the merits.\u201d[5]<\/a>  If there is any reasonable basis for the litigation, the analysis ends and immunity applies.  \u201cOnly if challenged litigation is objectively meritless may a court examine the litigant\u2019s subjective motivation.\u201d[6]<\/a>  At that stage, the question is whether a defended used \u201cthe governmental process itself\u2014as opposed to the outcome<\/em> of that process\u2014as\u201d a weapon.[7]<\/a>  In other words, a party does not lose protection simply because it seeks a competitive advantage or hopes to harm a rival through lawful governmental action. <\/p>\n\n\n\n

Anti-SLAPP Statutes and the Noerr-Pennington<\/em> Doctrine are Not Interchangeable<\/strong><\/h2>\n\n\n\n

The rise of anti-SLAPP statutes has caused many practitioners to overlook the Noerr-Pennington <\/em>doctrine, but anti-SLAPP statutes and Noerr-Pennington<\/em> are not interchangeable. <\/p>\n\n\n\n

Many anti-SLAPP statutes focus on speech or petitioning relating to matters of public concern.[8]<\/a>  Courts applying those statutes often must determine whether the challenged activity involves public participation, public issues, or matters of societal importance.[9]<\/a>  If the dispute is purely private, anti-SLAPP protection may be unavailable. <\/p>\n\n\n\n

While anti-SLAPP defenses are hamstrung by the public concern element, the Noerr-Pennington<\/em> doctrine imposes no such requirement.  Whether the party seeks a zoning variance, files an administrative complaint, initiates litigation, opposes a competitor\u2019s permit application, or advocates for governmental action affecting only a handful of private actors, the constitutional protection remains the same.  The inquiry is not whether the issue is newsworthy or politically significant; the inquiry is whether the conduct constitutes genuine petitioning activity.<\/p>\n\n\n\n

That distinction is particularly important in commercial litigation.  Businesses frequently engage in petitioning activity directed at courts, agencies, licensing boards, or regulatory bodies over disputes that have little public significance.  Such disputes may fall outside the reach of anti-SLAPP statutes while remaining squarely within the protection of Noerr-Pennington<\/em>.<\/p>\n\n\n\n

The doctrine has also proven resistant to efforts to create broad motive-based exceptions.  Courts have repeatedly held that allegations of improper intent, including claims that petitioning activity was retaliatory, do not by themselves defeat immunity.  As the Fifth Circuit observed in Bayou Fleet, Inc. v. Alexander<\/em>, 234 F.3d 852, 861\u201362 (5th Cir. 2000), the Supreme Court has never recognized a separate retaliation exception to the Noerr-Pennington <\/em>doctrine.<\/p>\n\n\n\n

Noerr-Pennington <\/em><\/strong>Remains a Potent Defense<\/strong><\/h2>\n\n\n\n

Despite being overshadowed by anti-SLAPP statutes, the Noerr-Pennington <\/em>doctrine remains a formidable defense.  It is derived from the First Amendment itself, applies across a wide range of petitioning activities, and frequently can be asserted at the pleading stage.[10]<\/a>  Courts have also imposed substantial burdens on plaintiffs seeking to overcome the doctrine, requiring specific factual allegations supporting application of the sham exception.  For businesses facing claims arising from their litigation efforts, administrative filings, lobbying efforts, or other petitioning conduct, the Noerr-Pennington<\/em> doctrine deserves renewed attention.  <\/p>\n\n\n\n
