Robert D. MacMahon
Secured summary judgment in Philadelphia County CCP for the defendants and prevailed in an appeal to the Pennsylvania Superior Court in a matter of first impression, when the Court held in Donald Newell v. Mont. W., 2017 PA Super 15 (Jan. 19, 2017), that a landowner does not owe a duty to its business invitees who are injured on a public roadway adjoining the landowner's property.
Successfully achieved a defense verdict in a five-day jury trial. Rob’s client was a building engineer in a case involving an electrical shock accident. The plaintiff was attempting to remove the copper wire from a live switchgear box when he received a substantial electric shock which resulted in the amputation of his middle and ring fingers from his left hand. The plaintiff claimed he was told by the building engineers that the switchgear had been dead for 20 years. The building engineers of Rob’s client denied this and testified they told the plaintiff that the switchgear was hot and not to touch it. The plaintiff and the defendant building engineer each presented expert testimony from an electrical engineer and a doctor. The co-defendant building owner/building management denied knowing the plaintiff and his friend were in in the building, but both the plaintiff and his friend testified to the contrary. The co-defendant building owner/building management settled with the plaintiff on a Joint tortfeasor release while the jury was deliberating. The jury found the defendant building engineer negligent, but the negligence was not the cause of the injuries. The verdict was therefore rendered in favor of the defendant building engineer.
Obtained a defense verdict after 15 days of trial in the Philadelphia County Court of Common Pleas. He represented a property owner of a Class A building in Philadelphia along with the property management company for the building. The plaintiff’s settlement demand was $7.2 million and no offer was ever made. She was claiming permanent disability via Complex Regional Pain Syndrome. The plaintiff posted in excess of $4.1 million in economic damages to the jury. The plaintiff presented 21 witnesses in her case-in-chief, including six expert witnesses, four on damages. The defendants presented five expert witnesses on damages and an expert on liability, along with fact witnesses. The jury found no negligence attributable to any of the defendants.
