In each of these cases the initiation and enforcement of the program under attack involved a mixture of private and public decision making. In each case, notwithstanding the state participation in the decision, the private party exercised sufficient freedom of choice to enable the Court to conclude that he should be held responsible for the consequences of his decision. . . . There is nothing unjust in a conclusion that respondents participation in the decision is sufficiently significant to require that its conduct implementing the decision, like comparable conduct by unregulated businesses, conform to applicable federal law. Accordingly, even though there may be cases in which the States participation in a decision is so dominant that it would be unfair to hold a private party responsible for his conduct in implementing it, this record discloses no such unfairness.

The distribution of electric light bulbs in Michigan is unregulated. [N]either the Michigan Legislature, nor the Commission, has ever made any specific investigation of the desirability of a lamp-exchange program or of its possible effect on competition in the light bulb market. Other utilities regulated by the Michigan Public Service Commission do not follow the practice of providing bulbs to their customers at no additional charge. The Commissions approval of respondents decision to maintain such a program does not, therefore, implement any statewide policy relating to light bulbs. We infer that the States policy is neutral on the question whether a utility should, or should not, have such a program.

Broadly speaking, the Parker doctrine represents a judgment by the Supreme Court that, in regulating anticompetitive business conduct, Congress was not seeking to regulate the states themselves; and the states include their executive branches quite as much as their legislatures and their courts. The municipalities have been given less protection under Parker on the stated ground that technically speaking, they are not the state. . . .

In these cases, the Administrators interpretation represents a reasonable accommodation of manifestly competing interests and is entitled to deference: the regulatory scheme is technical and complex, the agency considered the matter in a detailed and reasoned fashion, and the decision involves reconciling conflicting policies. Congress intended to accommodate both interests, but did not do so itself on the level of specificity presented by these cases . . . . While agencies are not directly accountable to the people, the Chief Executive is, and it is entirely appropriate for this political branch of the Government to make such policy choicesresolving the competing interests which Congress itself either inadvertently did not resolve, or intentionally left to be resolved by the agency charged with the administration of the statute in light of everyday realities.

[O]ften it is difficult to determine whether the state has a regulatory program designed to supplant the operation of the free market. It may have a regulatory program but one that can coexist happily with the full enforcement of federal antitrust principles because the program does not require the supplanting of competition . . . .
Hardy v. City Optical Inc., 39 F.3d 765, 768 (7th Cir. 1994).
States must accept political responsibility for actions they intend to undertake. It is quite a different matter, however, for federal law to compel a result that the States do not intend but for which they are held to account. Federalism serves to assign political accountability, not to obscure it. Neither federalism nor political responsibility is well served by a rule that essential national policies are displaced by state regulations intended to achieve more limited ends. For States which do choose to displace the free market with regulation, our insistence on real compliance with both parts of the Midcal test will serve to make clear that the State is responsible for the price fixing it has sanctioned and undertaken to control.

[S]ince the Oregon statute speaks solely of authorizing the OPUC to approve exclusive service territories, the states clearly articulated policy is to have the OPUC decide whether to sanction anticompetitive conduct. It follows, therefore, that we must look to the decisions of the OPUC to determine whether PGEs conduct was part of a clearly articulated state policy.
