Suburban Restoration Co., Inc. appeals from an order of the United States District Court for the District of Connecticut, T.F. Gilroy Daly, J., enforcing Magistrate Thomas P. Smith’s order dismissing Suburban’s complaint against defendants ACMAT Corporation (ACMAT), Laborers’ International Union of North America, Local 665 AFL-CIO (the Union), and Robert D. Witte. Magistrate Smith and Judge Daly concluded that Suburban’s suit under the Connecticut Unfair Trade Practices Act (CUTPA), Conn.Gen.Stat. § 42-110b(a), аnd the common law of tortious interference with a business expectancy, for damages resulting from defendants’ filing of a lawsuit in a Connecticut state court was barred by the first amendment to the United States Constitution as interpreted in the
Noerr-Pennington
doctrine. The
Noerr-Pennington
doctrine refers to a trilogy of Supreme Court cases,
Eastern Railroad Presidents Conference v. Noerr Motor Freight,
I. Background
This case arises out of an invitation to bid issued by the City of Bridgeport, Connecticut, on October 3, 1980, seeking proposals for a contract to renovate and remove asbestos from a school building. Appellant Suburban and appellee ACMAT were among the bidders; Suburban submitted the lowest bid, and the city began the process of awarding the contrаct to Suburban. ACMAT, as a disappointed bidder, and appellee Union, as a city taxpayer, then brought suit against officials of the city in the Connecticut Superior Court, through their attorney, appellee Witte. Suburban was not a party to the suit. ACMAT and the Union sought a writ of mandamus and an injunction against the award of the contract to Suburban on the ground that Suburban’s bid was deficient. The suit was settled when the city agreed not to award the contract to Suburban, but to resubmit the project to bidding. Suburban was not successful in the second round of bidding.
This lawsuit, in the federal courts because of diversity, ensued. Appellant Suburban claims that the stаte court action was a groundless suit constituting an unfair method of competition and an unfair and deceptive trade practice under CUTPA and a tortious interference with a business expectаncy under the common law that caused appellant to lose $700,000. Appellees moved to dismiss for failure to state a cause of action and for summary judgment. These motions presented several issues of state law, including whether filing a groundless lawsuit can be an unfair trade practice under CUTPA. Magistrate Smith, however, granted the motion to dismiss on a ground not raised by the parties. He found that the threshold issue in the case was whether the complaint alleged conduct falling within the sham exception to the NoerrPennington doctrine, and he concluded that it did not, so that the doctrine barred Sub *100 urban’s suit. Judge Daly adopted this рosition in his order enforcing the dismissal.
The Noerr-Pennington doctrine and the sham exception were developed by the Supreme Court in a series of cases in which it was alleged that defendants’ attempts to obtain commercially favorable actions from different branches of government violated the Sherman Act. Eastern R.R. Presidents Conference v. Noerr Motor Freight, Inc., supra (seeking legislation); United Mine Workers v. Pennington, supra (attempting to influence executive actions); California Motor Transport Co. v. Trucking Unlimited, supra (instituting administrative and judicial proceedings). In Noerr and Pennington the Court held that the activity alleged was outside the scope of the Sherman Act; in California Motor Transport, the Court recognized that the act of filing a legitimate lawsuit was within the Noerr-Pennington doctrine, i.e., not covered by the Sherman Aсt, but held that the Act can reach sham litigation such as the multiple baseless proceedings alleged in California Motor Transport. Since Suburban concedes that the state court suit does not fit into the sham exception, California Motor Transport would сlearly have required dismissal if Suburban had brought suit under the Sherman Act, instead of under CUTPA and the common law. But the question remains whether the result must be similar under state law. The parties have focused their arguments on aрpeal on the question raised by the magistrate’s decision, namely, whether the Noerr-Pennington doctrine is mandated by the United States Constitution. This issue apparently has not been definitively resolved by the Supreme Court and hаs not been squarely addressed in this circuit. See generally Fischel, Antitrust Liability for Attempts to Influence Government Action: The Basis and Limits of the Noerr-Pennington Doctrine, 45 U.CM.L. Rev. 80, 94-104 (1977).
Magistrate Smith concluded without much discussion that the doctrine is constitutionаlly mandated, and that therefore it must apply to Connecticut’s law as well as to the Sherman Act. There is some support for this position in the cases, but it is.not conclusive.
Noerr
expressly refrains from deciding whеther the activities complained of are protected under the first amendment, basing its holding solely on a construction of the Sherman Act.
The decision in
Pennington
four years later adds nothing that is inconsistent with limiting
Noerr
to statutory construction. Indeed, Justice White’s majority opinion states that
Noerr
hеld that “[t]he Sherman Act ... was not intended to bar concerted action of this kind .... ”
Courts in other jurisdictions have taken this position. In
Pennwalt Corp. v. Zenith Laboratories, Inc.,
This circuit has not gone so far as to apply the
Noerr-Pennington
doctrine to state law causes of action. But it has, in the process of applying
Noerr-Pennington
and the sham exception to Sherman Act claims, explicitly described the doctrine аs an application of the first amendment. See
Landmarks Holding Corp. v. Bermant,
We are not bound to follow the language of
Landmarks Holding
and
Miracle Mile
quoted above, since it was not necessary to the holdings of those cases, and since the first amendment basis of the doctrine was not treated as an issue by the court or by the parties. But we find it unnecessary to decide this constitutional issue at all. It remains an open question whether, аs a matter of statutory construction, filing a groundless lawsuit is the sort of “unfair trade practice” that CUTPA was intended to prohibit. Apparently the Connecticut courts have never addressed the issue. In the absеnce of Connecticut precedent construing CUTPA, we must “do the best we can in estimating ‘what the state court would rule to be its law.’ ”
Bailey Employment System, Inc. v. Hahn,
We affirm the judgment of the district court.
