Michael J. Silvestri (Of Counsel-Baltimore, MD) and Pascal Moleus (Associate-Baltimore, MD) obtained summary judgment in favor of a client utility contractor, resulting in dismissal of a negligence claim over a construction laborer who was involved in a manhole cover explosion at a construction site, resulting in serious injuries to the laborer’s head and abdomen and the amputation of two of the laborer’s right foot toes. In granting the motion, the Circuit Court for Baltimore City, Maryland, found that the laborer alleged professional negligence against the utility contractor but failed to produce required expert testimony establishing either the professional standard of care owed by the utility contractor or causation.
