Helen Palsgraf, Respondent, v. The Long Island Railroad Company, Appellant Facts A passenger carrying a package, while hurrying to catch and board a moving Long Island Rail Road train, appeared to two of the railroad's (Defendant's) employees to be falling. The employees were guards, one of whom was located on the car, the other of whom was located on the platform. The guard on the car attempted to pull the passenger into the car and the guard on the platform attempted to push him into the car from behind.The guards' efforts to aid the passenger caused the package the passenger was holding to fall on the rails.

Unbeknownst to the guards, the package, which was approximately 15 inches (38 cm) long and wrapped in newspaper, contained fireworks, and the package exploded when it hit the rails. The shock reportedly knocked down scales at the other end of the platform (although later accounts suggest that a panicking bystander may have upset the scale), which injured Mrs. Helen Palsgraf (Plaintiff). Palsgraf sued the railroad, claiming her injury resulted from negligent acts of the employee.The trial court and the intermediate appeals court found for Palsgraf (Plaintiff) by verdict from a jury, and Long Island Rail Road appealed the judgment. The Court of Appeals (the highest court in New York) reversed and dismissed Palsgraf's complaint, deciding that the relationship of the guard's action to Palsgraf's injury was too indirect to make him liable.

Cardozo, writing for three other judges, wrote that there was no way that the guard could have known that the package wrapped in newspaper was dangerous, and that pushing the passenger would thereby cause an explosion.The court wrote that "there was nothing in the situation to suggest to the most cautious mind that the parcel wrapped in newspaper would spread wreckage through the station. If the guard had thrown it down knowingly and willfully, he would not have threatened the plaintiff's safety, so far as appearances could warn him. " Without any perception that one's actions could harm someone, there could be no duty towards that person, and therefore no negligence for which to impose liability (duty is a matter of aw to be decided by a judge; therefore, a finding that there was no duty was sufficient to overturn the jury's guilty verdict). The court also stated that whether the guard had acted negligently to the passenger he pushed was irrelevant for her claim, because the only negligence that a person can sue for is a wrongful act that violates their own rights.

Palsgraf could not sue the guard for pushing the other passenger because that act did not violate a duty to her, as is required for liability under a negligence theory. It is not enough for a plaintiff to merely claim an injury. If the harm was not willful, he must show that the act as to him had possibilities of danger so many and apparent as to entitle him to be protected against the doing of it though the harm was unintended. " This concept of foreseeability in tort law tends to limit liability to the consequences of an act that could reasonably be foreseen rather than every single consequence that follows. Otherwise, liability could be unlimited in scope, as causes never truly cease having effects far removed in time and space (ex.

the Butterfly Effect).
