Chicago ? State Farm has filed a lawsuit alleging that a Florida company and a recruiter arranged unnecessary, fraudulent medical tests on auto accident victims at chiropractors’ offices across the country.

The civil racketeering lawsuit challenges more than 600 insurance claims filed in 40 states and is seeking more than $4.5 million in damages.

Named as defendants in the lawsuit filed Tuesday are Brad Goldstein of Boca Raton, Fla., whose businesses provided technicians and mobile equipment to perform the tests; David Goroway of Fort Lauderdale, Fla., who recruited chiropractors for Goldstein; Dr. Gary Weiss, a Florida neurologist; and Robert J. Brown, Weiss’ former office administrator.

Brown said he had not seen the lawsuit but defended the tests as “effective tools.”

“Insurance carriers have a lot of power,” Brown said. “They can file suits and scare everybody, but that doesn’t mean they’re right.”
