California’s insurance commissioner announced the end to a pair of civil suits, filed over his agency’s efforts to force insurance companies to stop investing in corporations working in Iran.

California Commissioner Steve Poizner filed a lawsuit challenging the state Office of Administrative Law’s (OAL) ruling that his efforts to stop insurers from investing in Iran constituted an underground regulation.

The California Office of Administrative Law (OAL) declared the state insurance commissioner’s actions against insurers holding investment relations with Iran to be “improper.”

National insurance companies are defending their business practices after being included on a list released by the California Department of Insurance of those refusing a voluntary moratorium on future investments in firms linked to Iran.

A public hearing into why insurers would not disclose their investments in Iran was canceled after all 1,327 companies licensed in the state outlined their financial dealings to state regulators.

Designating Iran as a “state sponsor of terrorism,” California’s insurance commissioner wants $12 billion in investments by companies doing business in the state completely divested in a move that could be mirrored by other state regulators.
