Ohio Attorney General Marc Dann sued Marsh & McLennan and four of the nation’s largest insurance companies.  Having settled with the state of New York back in early 2005 for $850 million, Marsh faces identical allegations.

Dann claims that Marsh and the insurers violated the state’s anti-trust laws and orchestrated a conspiracy to eliminate competition in the commercial insurance industry.

Full coverage of this new lawsuit will be in the Sept. 25 issue of LexisNexis Mealey’s Publication:  Insurance Broker Liability.
