A Fulton County judge tossed out a legal malpractice complaint against Taylor English Duma and attorney Michael Trotter three weeks before trial, ruling that, even if the firm were negligent, the plaintiff could not prove the firm caused his claimed losses.

Engineer Michael LaLonde claimed that a contract drawn up by Taylor English lawyers allowed his partners to dissolve their company and lose the rights to a medical device he invented, costing him millions of dollars in capital and potential profits.
