For the class

Morgan & Morgan's John Yanchunis is tackling the biggest class-action lawsuit in history, as lead counsel in the Yahoo data breach case.

But work like this isn't far-fetched for the Tampa-based lawyer, who has had his hands in several notable class-action cases regarding data breaches. The list includes suits against The Home Depot Inc. and Target Corp.

Northern District of California Judge Lucy Koh, in a Feb. 9 order, determined Yanchunis would be the most appropriate lead plantiffs' counsel and chair of the plantiffs' executive committee in the Yahoo case. Yanchunis beat out three other firms for the position.
