A multimillion-dollar class action against The Hartford Insurance Co. had the semblance of David vs. Goliath — a group of automotive body shops taking on an insurance industry powerhouse.

Thomas Rohback, a Hartford, Conn., partner at Axinn, Veltrop & Harkrider, set out to convince jurors that the little-guy perception was just a facade. Rohback focused on showing that Hartford’s policies were not driving the shops out of business, as they alleged. The shops, he maintained, were profitable — and looking to eliminate competition.
