When attorney Mark Goodheart asked opposing counsel for a copy of the surveillance footage captured by a video camera on the front of the train that collided with his client’s truck, he had no idea he was sparking an electronic discovery fight that would last nearly two years.

In Pannunzio v. Norfolk Southern, Goodheart, an attorney with Cohen, Placitella & Roth in Philadelphia, represented plaintiff William M. Pannunzio, who was injured when his delivery truck was hit by a train owned and operated by defendant Norfolk Southern Corp., according to court papers.
