In Paul v. Virginia (75 U.S. (8 Wall.) 168 (1868)), the Supreme Court ruled that "[i]ssuing a policy of insurance is not a transaction of [interstate] commerce." United States v. South-Eastern Underwriters Ass ' n. (322 U.S. 533 (1944)) held that the federal antitrust laws were applicable to an insurance association's interstate activities in restraint of trade. Although the 1944 Court did not specifically overrule its prior determination, the case was viewed as a reversal of 75 years of precedent and practice, and created significant apprehension about the continued viability of state insurance regulation and taxation of insurance premiums. Congress' response was the 1945 McCarran-Ferguson Act. In addition to preserving the states' ability to tax insurance premiums, McCarran-Ferguson prohibits application of the federal antitrust laws and similar provisions in the Federal Trade Commission Act, as well as most other federal statutes, to the "business of insurance" to the extent that such business is regulated by State law --except that the antitrust laws are applicable if it is determined that an insurance practice amounts to a boycott. Inasmuch as "[t]he primary purpose of the McCarran-Ferguson Act was to preserve state regulation of the activities of insurance companies since it was the power of the states to regulate and tax insurance companies that was threatened after ... South-Eastern Underwriters ...," we first answer the questions, "What is insurance?"; and, "is it defined pursuant to state or federal law?" Then, given that the statute addresses itself to the "business of insurance," this report sets out some judicial opinions about just what does--and does not--constitute the "business of insurance," as well as state regulation of such business, and the scope of McCarran's "boycott" exception. Finally, it will note some McCarran-related legislation introduced in the 110 th and 109 th Congresses, and discuss, briefly, the possible consequences of the measures, especially in light of the non-statutory state-action doctrine in antitrust law. In response to the Securities and Exchange Commission's insistence that insurers issuing variable annuity contracts register them as securities under the federal securities laws, the insurers asserted that McCarran-Ferguson shielded them from federal regulation, but that even if it did not, they qualified for the insurance exemptions from the federal securities laws. The Supreme Court, reversing lower court decisions, held that neither state regulation of variable annuities nor their issuance by insurers qualified the annuities as "insurance." Accordingly, neither insurers nor state regulators could (1) invoke McCarran-Ferguson as a shield against federal regulation of variable annuities or (2) qualify as beneficiaries of the insurance exclusions in the federal securities laws. Moreover, the case established that the definition of "insurance" under McCarran-Ferguson is a federal, not a state, question. NationsBank v. VALIC made a similar determination concerning the sale of fixed annuities, which are sold both by insurers and by banks. The Court agreed with the Comptroller of the Currency that in the provision of fixed annuities, "banks are essentially offering financial investment instruments of the kind congressional authorization permits them to broker. Hence, [it was reasonable to characterize the] permission NationsBank sought as an 'incidental powe[r] ... necessary to carry on the business of banking.'" The scope of McCarran-Ferguson protection--the statute's applicability in instances in which insurance companies are actors in an area in which the federal government clearly has not ceded its regulatory authority to the states--has been addressed numerous times, both by the Supreme Court and the lower federal courts. Generally, it has been found that federal statutes are not trumped by McCarran except where the "business of insurance" is directly involved, or where a state insurance regulatory scheme or state insurance administration would be adversely affected. Securities and Exchange Commission ( SEC ) v. National Securities, Inc. , limited the scope of the term "business of insurance" to activities that involved only insurance companies' relationships with their policyholders. The merger of two insurance companies was challenged by the SEC, which alleged violations of federal securities laws, despite the merger's approval by the Arizona Director of Insurance. National Securities argued that the merger was in compliance with state law, and that the McCarran-Ferguson Act precluded application of an inconsistent federal law. The Court disagreed, holding that a state statute aimed at protecting the stockholders of insurance companies was not a statute regulating the "business of insurance": " whatever the exact scope of the statutory term, it is clear where the focus was [in McCarran]--it was on the relationship between the insurance company and the policyholder. [Only s]tatutes aimed at protecting or regulating this relationship ... are laws regulating the ' business of insurance. ' " About 25 years after National Securities limited the term "business of insurance" to activities involving only insurance companies' relationships with their policyholders, the Court extended that ruling. It held, in U.S. Department of Treasury v. Fabe , that state laws addressing the liquidation of insurers constitute "the business of insurance"--and, under McCarran-Ferguson, preempt conflicting federal statutes-- but only to the extent that they are necessary to protect the insolvent's policyholders. The United States had argued that an Ohio statute determining the order in which claims against an insolvent insurance company are to be paid should be preempted by the federal priority statute authorizing the payment of U.S. claims against an insolvent entity. The Court disagreed, however, with respect to the payment of policyholder claims and payment of the administrative expenses "reasonably necessary to" the payment of policyholder claims, and said: "[t]he primary purpose of a statute that distributes the insolvent insurer's assets to policyholders in preference to other creditors is identical to the primary purpose of the insurance company itself: the payment of claims made against policies." Later decisions continued the distinction made by Fabe between statutes that address the "business of insurance" and may, therefore, "reverse-preempt" conflicting federal statutes, and those that will be preempted under traditional, constitutional principles. For example, International Ins. Co. v. Duryee involved an Ohio statute that "effectively prohibit[ed] out-of-state insurance companies from removing cases from [Ohio] state to federal court by barring such companies from further business in Ohio." The United States Court of Appeals for the Sixth Circuit emphatically stated there, that "[t]he McCarran-Ferguson Act was not meant to protect a statute so tangentially related to insurance from the general rule of federal law supremacy." The court first quoted from a 1922 Supreme Court ruling, Terral v. Burke Const. Co. , [A] state may not, in imposing conditions upon the privilege of a foreign corporation's doing business in the state, exact from it a waiver of the exercise of its constitutional right to resort to the federal courts, or thereafter withdraw the privilege of doing business because of its exercise of such right, whether waived in advance or not. And then it quoted from Fabe itself: the Fabe Court found that the "broad category of laws enacted 'for the purpose of regulating the business of insurance' ... necessarily encompasses more than just the 'business of insurance.'" Group Life & Health Insurance Co. v. Royal Drug Co. stands for the proposition that McCarran-Ferguson's "exemption is for the 'business of insurance,' not the 'business of insurers.'" Independent retail pharmacies charged Blue Shield of Texas with price fixing in the negotiation of Pharmacy Agreements, based on which the insurance company had issued policies that facially entitled policyholders to purchase prescription drugs from any pharmacy. In reality, the independents argued, insureds were more likely to choose pharmacies that had entered into the "Pharmacy Agreements" because at those establishments (mostly larger, chain pharmacies) policyholders were required to pay only $2 for each prescription drug purchased; a "Pharmacy Agreement"-pharmacy would be reimbursed for its costs and the $2 charge would be its profit. At nonparticipating pharmacies (mostly smaller, independent stores), insureds would be expected to pay the entire cost of any drug, and then seek reimbursement from Blue Shield for 75% of the cost. The Supreme Court rejected Blue Shield's argument that the McCarran-Ferguson Act made the Pharmacy Agreements immune to prosecution under the antitrust laws, the Court emphasizing that although "the agreements between Blue Shield and the participating pharmacies ... [may] serve ... to minimize the costs Blue Shield incurs in fulfilling its underwriting obligations," they "do not involve any underwriting or spreading of risk," are not integral to the relationship between the insurer and the insured, and are not limited to entities within the insurance industry. In Gilchrist v. State Farm Mutual Auto Ins. Co. , the United States Court of Appeals for the Eleventh Circuit appeared not to continue the Royal Drug reasoning. When policyholders challenged the practice of certain automobile insurers of improperly limiting the scope of insurance coverage for auto body repairs, the court distinguished some earlier decisions concerning the scope of the McCarran-Ferguson exemption. The appeals court first emphasized that Royal Drug (as well as a later case in which chiropractors challenged the insurance-company policy of peer reviewing chiropractic fees and practices ) concerned challenges by non-policyholders to insurance companies' agreements with third parties. But, it noted, "Gilchrist [on the other hand] is a policyholder whose claim is that Insurers have charged excessive premiums for inferior repair work on her automobile." That, it said, is a direct challenge to the insurance policy itself, and the company's rate-making decisions, "the paradigmatic example of the conduct that Congress intended to protect by the McCarran-Ferguson Act." Courts have almost unanimously determined that state regulation need not meet the standards of federal antitrust law in order for McCarran-Ferguson to apply, and that the federal government may not require "uniform state regulation." However, whether state regulation needs to meet any particular standard to qualify as preempted "regulation"has remained a question. In 1958, in Federal Trade Commission (FTC) v. National Casualty Co. , for example, the Court had already decided that McCarran-Ferguson "withdrew from the ... Commission the authority to regulate [insurers'] advertising practices in those States which are regulating those practices under their own laws"; and that the FTC could not, therefore, order the multistate-insurance-company defendants to stop using advertising that the Commission deemed false, deceptive, and misleading in violation of section 5 of the FTC Act. But the Court expressly declined to examine whether the states' laws had been effectively applied, finding it sufficient that "[e]ach State in question ha[d] enacted prohibitory legislation which proscribe[d] unfair insurance advertising and authorize[d] enforcement through a scheme of administrative supervision." Most decisions have found it sufficient for McCarran-Ferguson "regulated by state law" purposes that state insurance departments have jurisdiction over insurance practices and the authority to act, whether they exercise their authority or not. In 1982, however, a federal district court in Florida held that "it is essential to conduct some sort of inquiry into the adequacy and effectiveness of state legislation asserted to preempt the antitrust laws." Whether the boycott referred to in the statute is solely a boycott of entities within the insurance industry, or a consumer-protection facet of the otherwise industry-friendly McCarran law, was addressed in St. Paul Fire Marine Insurance Co. v. Barry, where the Supreme Court ultimately found in favor of the latter. In St. Paul, doctors sued four companies that sold medical malpractice insurance, alleging that one of the companies had changed its malpractice policy in a manner unfavorable to the doctors, who were then unable to take their business elsewhere because the other companies refused to sell them malpractice policies of any sort. This, the doctors charged, was the result of an unlawful conspiracy and constituted a boycott in violation of the antitrust laws. The district court held that the purpose of McCarran's "boycott" language was to protect industry members from being "black-listed." The court of appeals reversed, finding that the protection of insurance consumers by the "usual reading of 'boycott, coercion, or intimidation' does not ... pose a grave danger to state authority." The Supreme Court agreed, holding that the "conduct in question accords with the common understanding of a boycott": if Congress had intended to limit the scope of the boycott exception to industry members, the Court said, it would have done so explicitly. In Hartford Fire Ins. Co. v. California , however, a divided Court--differentiating between "conspiracy" and "boycott," refused to find for the nineteen states which alleged that the practices of several U.S. and foreign insurers--acting to force other insurers to sell only policies with terms similar to those in the defendants' policies--violated the antitrust laws. It distinguished between a true boycott (which the Court defined as a concerted refusal to deal on matters unrelated or collateral to the insurance contract at hand) and a McCarran-protected mere concerted refusal to deal on certain contract terms deemed to be central to the insurance contract, but noted that absent McCarran-Ferguson, either would violate the antitrust laws: A conspiracy is a combination of two or more persons acting in concert to accomplish a common unlawful purpose. ... Of course as far as the Sherman Act (outside the exempted insurance field) is concerned, concerted agreements on contract terms are unlawful. ... The McCarran-Ferguson Act, however, makes that conspiracy lawful ... unless the refusal to deal is a 'boycott.' At least two, bipartisan bills to "end the insurance industry's exemption from the requirements of [the antitrust] laws," by amending the McCarran-Ferguson Act were introduced in the 110 th Congress. The identical bills-- S. 618 (Leahy, with the co-sponsorship of Senators Specter, Lott, Reid, and Landrieu) and H.R. 1081 (DeFazio, with the co-sponsorship of Representatives Taylor, Jindal, Melancon, Alexander, and Jones [NC])--would have specified that the Federal Trade Commission Act "as it relates to unfair methods of competition" would, in addition to the Sherman Act and Clayton Act, be applicable to the "business of insurance," thus eliminating the phrase "to the extent that such business is not regulated by State law." Both however, would have specified that the Federal Trade Commission Act, "as it relates to areas other than unfair methods of competition" would continue to be applicable to the "business of insurance to the extent that such business is not regulated by State law." Each would have restored the authority of the Federal Trade Commission, pursuant to its 15 U.S.C. SS 46(a) powers, to investigate the insurance industry; that authority was removed in 1980 by section 5 of P.L. 96-252 , Federal Trade Commission Antitrust Improvements Act of 1980, except to the extent that such studies were specifically requested by Congress. Both measures would have deleted 15 U.S.C. SS 1013, in which the 79 th Congress (1) made the antitrust laws inapplicable to the "business of insurance" until June 30, 1948; but (2) specified, at the same time, that the antitrust laws would nevertheless be applicable to boycotts, coercion, or intimidation, or agreements to create or further those activities. Lastly, each would have permitted the Department of Justice and the FTC to "issue joint statements of their antitrust enforcement policies regarding joint activities in the business of insurance." Measures in the 109 th Congress ( e.g. , S. 1525 ; H.R. 3359 ) would have, notwithstanding McCarran-Ferguson, prohibited commercial insurers who provide medical malpractice insurance from "price fixing, bid rigging, or market allocation in connection with" such provision. Joint rate setting, generally accepted as a method of establishing premium rates, has long been considered valid as a McCarran-Ferguson "business of insurance" activity, and many states explicitly authorize it. The courts' increasingly narrow interpretation of "the business of insurance" would, however, arguably exclude at least the latter two, specified activities, even absent such language; similarly, such language in future bills would not likely be necessary to enable courts to find, for example, that bid-rigging or market allocation are outside the scope of McCarran protection. H.R. 2400 would have established a Commission--the Emergency Malpractice Liability Commission (EMLIC)--to "examine the causes of soaring medical malpractice premiums and propose a comprehensive strategy to alleviate the impact of the crisis" there; and submit a report of its findings to Congress, which would have been obligated to hold hearings on the report within six months after it was received. The Commission would have been directed, for example, to "investigate and determine whether a causal relationship exists between skyrocketing malpractice insurance premiums, jury awards, decreased accessibility and affordability of health care; and the increase in the number of physicians moving, quitting or retiring from practices.... " The bill remained pending in committee. H.R. 2401 , unlike the bills discussed above, would have applied without reference to any specific line of insurance. It would have amended McCarran-Ferguson to clarify that the antitrust laws would be generally applicable, except with respect to the smallest entities in the insurance industry, to such activities as price fixing ( e.g ., currently permissible joint rate setting), geographic market allocation, "tying the purchase of insurance to the sale or purchase or another type of insurance," or monopolization of "any part of the business of insurance." Contracts or conspiracies for the purpose of joint collection of historical loss data, however, would be explicitly permitted. Again, however, given the courts' narrowing definition of the "business of insurance," they would not be likely, in any event, to find such activities as market allocation, tying, or monopolization protected by McCarran-Ferguson from the application of the antitrust laws. S. 4025 , "Insurance Industry Antitrust Enforcement Act of 2006," was introduced to "subject the insurance industry to Federal antitrust law." The bill would have amended SS 2(b) of McCarran-Ferguson (15 U.S.C. SS 1012(b)) to clarify that the federal antitrust laws would be applicable to the business of insurance "except to the extent [that] the conduct of a person engaged in the business of insurance is undertaken pursuant to a clearly articulated policy of a State [and] that is actively supervised by that State; ..." Those words appeared to represent tacit acknowledgment that (1) the original purpose of McCarran-Ferguson was to assure the ability of the states to regulate the business of insurance; and (2) the existence of the state action doctrine in antitrust law. That doctrine might easily afford immunity from prosecution under the federal antitrust laws to both (a) the narrowly interpreted "business of insurance" protection provided by McCarran-Ferguson, and (b) any other activity of insurance companies that the states choose to authorize and actively regulate. S. 2509 would have made, with certain exceptions, the federal antitrust laws applicable to federally licensed insurance producers "to the same extent as other businesses are subject to such laws," and would have retained the McCarran-Ferguson "business of insurance" exemption "to the extent that such insurers and producers are subject to State law." The state action doctrine, first enunciated by the Supreme Court in Parker v. Brown , has come to stand for the proposition that federalism dictates that the antitrust laws are not applicable to the states. It has, over the years since 1943, been interpreted, clarified and expanded to the point that it now confers antitrust immunity not only on the states qua states (including state agencies and officials acting in their official state capacities), or those private individuals who act in furtherance of state-directed activity, but also extends to those who act pursuant to state-sanctioned, but not necessarily mandated, courses of action. Its essence is captured in the two-part test set out in California Retail Liquor Dealers Ass ' n v. Midcal Aluminum Inc. There, the Court made clear first, that the challenged restraint must be "one clearly articulated and affirmatively expressed as state policy" (most generally via legislatively enacted statute), and second, the policy must be "actively supervised" (i.e., enforced) by the State itself. It is, thus, apparent that, since at least 1980, "regulated by state law" has been a prong of the judicially created state action doctrine in antitrust law, a doctrine which was developing simultaneously with McCarran-Ferguson case law. As McCarran-Ferguson immunity for activities constituting the "business of insurance" has steadily been narrowed since the act's passage in 1945, and legislative action toward limiting or abolishing the exemption entirely has increased, the doctrine of state action immunity from prosecution under the federal antitrust laws has steadily been expanded since the doctrine was first announced in 1943. Presently, entities acting at the behest or authorization of a state regulatory scheme--so long as that scheme is envisioned by the state legislature in "clearly articulated" language, and so long as the state exercises sufficient "active supervision" over the authorized but possibly anticompetitive activities of private entities--become the equivalent of "derivative beneficiaries" of the states' own immunity from prosecution under the federal antitrust laws. Although virtually every state maintains some form of insurance regulation, whether existing state regulation of the insurance industry is sufficient to satisfy the "active supervision" prong of Mical may not, however, always be clear or assured. Whether, especially in view of the existence and potential application of the state-action doctrine, legislative efforts to circumscribe the scope of the McCarran-Ferguson Act will continue, is presently an unanswered question.

Summary:
In Paul v. Virginia (75 U.S. (8 Wall.) 168 (1868)), the Supreme Court ruled that "[i]ssuing a policy of insurance is not a transaction of [interstate] commerce." United States v. South-Eastern Underwriters Ass'n. (322 U.S. 533 (1944)) held that the federal antitrust laws were applicable to an insurance association's interstate activities in restraint of trade. Although the 1944 Court did not specifically overrule its prior determination, the case was viewed as a reversal of 75 years of precedent and practice, and created significant apprehension about the continued viability of state insurance regulation and taxation of insurance premiums. Congress' response was the 1945 McCarran-Ferguson Act. It prohibits application of the federal antitrust laws and similar provisions in the Federal Trade Commission (FTC) Act, as well as most other federal statutes, to the "business of insurance" to the extent that such business is regulated by State law--except that the antitrust laws are applicable if it is determined that an insurance practice amounts to a boycott. Early McCarran-Ferguson decisions mostly favored insurance companies. After 1969, however, the exemption for the "business of insurance" was generally limited to activities surrounding insurance companies' relationships with their policyholders. In 2003, the Supreme Court ruled that McCarran case law prohibiting the indirect application of federal antitrust (or other) laws to the "business of insurance" would no longer control with respect to those areas over which Congress has unquestionable legislative authority (e.g., ERISA, civil rights, securities), notwithstanding insurance-company involvement. The issue of amending McCarran Ferguson so as to further limit the scope of the exemption for the "business of insurance" continued to receive attention in the 110th Congress, with the introduction of at least two bipartisan measures. S. 618 would not only have eliminated the antitrust exemption provided by McCarran-Ferguson, it would also have restored the FTC's authority to investigate the insurance industry. An identical bill, H.R. 1081, was introduced in the House. Both bills would have retained the exemption for the applicability of the FTC Act, "as it relates to areas other than unfair competition." It is not known at this time whether the issue will be revisited in the 111th Congress. Even in the event the McCarran exemption were to be severely limited or totally eliminated, however, the state-action doctrine in antitrust law has the potential to mitigate the consequences of either. State action stands for the proposition that the federal antitrust laws do not apply to the states, nor to private individuals acting either under state order or authorization. To the extent that state regulation of insurance embodies "clearly articulated" state policy, and regulators "actively supervise" the activities of insurance companies, the industry's antitrust exemption could actually be broadened to include actions not clearly "the business of insurance." (Those phrases have been firmly embedded in the state-action-doctrine jurisprudence in the antitrust law for more than 25 years.) This report will be updated as needed.
