Phillips v. Delaware Power and Light
In Phillips v. Delaware Power and Light, Del. Supr., 59 Del. 179, 216 A.2d 281, 9 Storey 179 (1966) the plaintiffs sought recovery for damage to his home caused by a gas explosion from a gas main.
The theory of recovery was that the City of Wilmington had negligently performed street resurfacing work that caused the break in the main.
Since the plaintiff could not produce an expert witness who could testify to anything more than the possibility, not the probability, the acts of the City caused this break, the plaintiff could not establish a causal connection between the alleged wrongdoing and an injury.
