Results

Unanimous Defense Verdict in Premises Liability Civil Jury Trial Under COVID Restrictions

We obtained a unanimous defense verdict in a civil jury trial in Northampton County, Pa. under COVID restrictions. In this premises liability case, the plaintiff claimed he had slipped on snow and ice on a sidewalk and suffered a comminuted tri-malleolar fracture, requiring two surgeries. At trial, Jason demonstrated that the plaintiff failed to establish that the accident occurred on the property his client maintained as power-of-attorney, or that his client breached any limited duty owed to a licensee. The socially-distanced jury returned its verdict in favor of the defense in one hour.
