An initial contract might not violate the antitrust laws at the time of its formation but arguably could become violative of those same laws when one of the contracting parties later gains unlawful dominance and control over a market as a result of a series of contracts or acquisitions. 104 CA 685.

Cited. 35 CS 136.

Sec. 35-27. Monopolization or attempt to monopolize unlawful. Every contract, combination, or conspiracy to monopolize, or attempt to monopolize, or monopolization of any part of trade or commerce is unlawful.

Cited. 169 C. 344.

Such organizations, or the members thereof, shall not be held or construed to be illegal combinations or conspiracies or monopolies in restraint of trade, under the provisions of this chapter.

Cited. 179 C. 324.

Cited. 35 CS 136.

Subsec. (b):

Activities relative to interconnection of telephone devices, though regulated by state agencies, are not specifically directed or required by statute, and are therefore not immune from antitrust liability under Subsec. 169 C. 344. Cited. 181 C. 655, overruled, see 335 C. 174; 235 C. 1. Sec. 35-44b was inapplicable in present case concerning a state antitrust statute without federal parallel and did not require court to incorporate federal case law defining state action immunity into its construction of Subsec.; Subsec. has no parallel in federal antitrust statutes and its specific language, which provides qualified state action immunity for anticompetitive conduct that is specifically directed or required by statute, takes precedence over the general language of case law construing generalized provisions of federal statutes covering same subject matter; trial court improperly rendered summary judgment for defendants as there was a genuine issue of material fact as to existence of wholesale water market in southeastern Connecticut and defendants were not specifically directed or required by statute to engage in all of the anticompetitive activities and thus were not immune from antitrust liability under subsection. 273 C. 786. Given the city was acting in a proprietary rather than regulatory capacity when enforcing a project labor agreement in a pre-bid specification that required the successful bidder to perform all project work with union labor, the city was not entitled to qualified immunity for its anticompetitive conduct. 303 C. 402.

Sec. 35-32. Attorney General to bring actions in the name of state or as parens patriae. (a) The Attorney General, in the name of the state and on behalf of the people of the state, shall enforce the provisions of this chapter.

Such proceedings may pray that such violation be temporarily or permanently enjoined, or otherwise prohibited.

(b) The Attorney General may also, in his discretion, intervene and appear in any proceeding pending before any court, agency, board, or commission in this state in which matters related to this chapter are in issue.

(c) The Attorney General may also, in enforcing the provisions of this chapter, bring an action in the name of the state as (1) parens patriae for persons residing in the state with respect to damages sustained by such persons, or, if the court finds in its discretion that the interests of justice so require, as a representative of a class or classes consisting of persons residing in the state who have been damaged; or (2) parens patriae with respect to damages to the general economy of the state or any political subdivision thereof; provided that such damages shall not be duplicative of those recoverable under subdivision (1) of this subsection.

(d) The Attorney General may also bring a civil action in the name of the state in the district courts of the United States under the federal antitrust laws to recover damages and secure such other relief as provided for in such laws as (1) parens patriae for persons residing in the state with respect to damages sustained by such persons, or, if the court finds in its discretion that the interests of justice so require, as a representative of a class or classes consisting of persons residing in the state who have been damaged; or (2) parens patriae with respect to damages to the general economy of the state or any political subdivision thereof; provided that such damages shall not be duplicative of those recoverable under subdivision (1) of this subsection.

History: P.A. 75-508 and P.A. 75-567 substituted “chapter” for “part”, specified that attorney general acts “in the name of the state and on behalf of the people of the state”, specified that proceedings “may pray that such violation be temporarily or permanently enjoined, or otherwise prohibited” and added Subsec. (b); P.A. 76-218 added Subsecs. (c) and (d).

Subsec. (c):

Subdiv. (2) affords the state standing to pursue a parens patriae claim for damages to its general economy caused by violations of the Connecticut Antitrust Act. 286 C. 454.

Sec. 35-32a. Funds received by state re antitrust actions deposited in General Fund. (a) All (1) gifts or grants made to the state for antitrust enforcement purposes, (2) funds awarded to the state or any agency of the state for the recovery of costs and attorney's fees in an antitrust action, (3) civil penalties imposed pursuant to section 35-38, and (4) damages collected by the state for injuries to its business or property pursuant to a judgment or settlement agreement in an antitrust action, shall be deposited in the General Fund.

(a) by abolishing antitrust revolving fund and adding provision that all funds enumerated in Subdivs. (1) to (4), inclusive, shall be deposited in the general fund; amended Subsec. (b) by deleting authority of attorney general to expend funds from the revolving fund for expenses incurred in antitrust actions and adding provision that any balance remaining in the revolving fund on July 1, 1985, shall be transferred to the general fund.

Sec. 35-33. Superior Court jurisdiction. The Superior Court of this state is hereby vested with jurisdiction to prevent and enjoin violations of this chapter. Any action or proceeding brought by the state, or any private party, for violation of the provisions of this chapter shall be brought in the superior court of the judicial district where the offense, or any part thereof, is committed, or in any judicial district where any of the alleged offenders reside or are found, or any agent resides or is found, or where any proprietor, association, firm, partnership, or corporate defendant does business.

The Attorney General may institute proceedings on behalf of the state, its municipalities, school districts and other political subdivisions organized under the authority of this state in federal court to recover damages or to seek injunctive relief provided for under any provision of federal law comparable to the provisions of this chapter; provided, the authority of any such municipality, school district or political subdivision to bring such action on its own behalf shall not be impaired nor shall its authority to engage its own counsel in connection therewith be impaired.

Sec. 35-44b. Judicial construction of Connecticut Antitrust Act. It is the intent of the General Assembly that in construing sections 35-24 to 35-46, inclusive, the courts of this state shall be guided by interpretations given by the federal courts to federal antitrust statutes.

(P.A. 92-248, S. 2.)

Cited. 235 C. 1. Sec. 35-35 must be interpreted consistently with relevant provisions of federal case law. 260 C. 59. This section does not deprive the state of standing to pursue a parens patriae action for antitrust damages to its general economy pursuant to Sec. 35-32(c)(2) because this section does not incorporate the federal preclusion of general economy damages into the state antitrust scheme. 286 C. 454. To have standing to bring a claim under the antitrust act, a plaintiff must adequately plead both that it has suffered an antitrust injury and that it is an efficient enforcer of the antitrust act, thus a claim that a plaintiff has failed to allege an antitrust injury or that it has failed to allege that it is an efficient enforcer of the antitrust laws implicates the trial court's subject matter jurisdiction and should be raised by way of a motion to dismiss. 333 C. 672.

(b) Upon proof being made, at any hearing on a complaint under subsection (a) of this section, that there has been discrimination in price, the burden of rebutting the prima-facie case thus made by showing justification shall be upon the person charged with a violation of this section, and unless justification shall be affirmatively shown, an order terminating the discrimination may be issued; provided nothing herein contained shall prevent a seller rebutting the prima-facie case thus made by showing that his lower price to any purchaser or purchasers was made in good faith to meet an equally low price of a competitor.
