How it applies
Common Examples
2
State Tax on Out-of-State Insurers
Riverfront Developments, an out-of-state insurer, faces a discriminatory premium tax enacted by State X on policies sold to residents. Congress has passed legislation expressly authorizing states to impose such taxes on insurance to protect local markets. State X has enacted the required statute, satisfying the regulated-by-state-law condition and triggering the McCarran-Ferguson antitrust exemption.
Private Nursing Home Transfers
Riverside Healthcare, a privately operated nursing home receiving substantial Medicaid funding, adopts a policy of transferring certain patients. Extensive state statutes govern licensing, funding, and patient rights at such facilities. Those statutes illustrate the lower threshold referenced in the definition even though the transfer decisions themselves do not qualify as state action.

Frequently Asked

What level of state involvement satisfies regulated by state law under McCarran-Ferguson?+
Enactment of a statute addressing the insurance activity is enough. Active supervision or detailed rules are not required, and the standard is lower than the one for state-action immunity.
Supporting sources
Why does McCarran-Ferguson use a lower standard for regulated by state law than state-action immunity?+
A higher standard would render the McCarran exemption superfluous because the same conduct would already be protected under state-action doctrine. The statute therefore requires only the existence of a state law on the subject.
Supporting sources
Does a state need to enforce its insurance statute for the regulated-by-state-law condition to be met?+
No. The condition is satisfied by passage of the statute itself. Enforcement or active regulation is not necessary under the McCarran-Ferguson framework.
