In Soule vs. General Motors Corporation, Mr. Barbaro won a $1.65 million jury verdict for his client Terri Soule in a complex automobile defect case against General Motors Corporation.

General Motors Corporation was unwilling to concede defeat after the 12-0 jury verdict. Armed with unlimited resources, General Motors Corporation appealed the case all the way to the California Supreme Court.

After Mr. Barbaro argued for Ms. Soule before the Supreme Court Justices, the Court found in favor of Ms. Soule. This ruling created a landmark decision concerning the application of the consumer-expectation test in the area of products liability. To this day, this case is taught in every law school in the country.
