On a Long Island train platform in 1924, a man ran to catch a departing train. A guard on the platform pushed him aboard from behind. Another guard on the train pulled him up. In the confusion, the man dropped an unmarked package.
The package contained fireworks.
The fireworks exploded. The blast shook the platform. Something at the far end of the platform, a scale, tall and heavy, tipped and fell on a woman named Helen Palsgraf. She sued the railroad.
Did the railroad cause her injury? Yes, in the literal sense that every law student learns first: if the guards had not pushed the man, he would not have dropped the package, the fireworks would not have exploded, the scale would not have tipped, and Mrs. Palsgraf would have stayed on her feet. Cause-in-fact runs straight from the shove to the injury like a line of dominoes.
And the New York Court of Appeals said: not good enough.
The opinion was written by Benjamin Cardozo, one of the great writers ever to sit on a bench, and it is one of the strangest and most beautiful things in American law. Cardozo did not deny the domino line. He drew a different one. The question, he said, was not whether the railroad’s negligence led to Mrs. Palsgraf’s injury. The question was whether the railroad’s negligence was aimed at a risk it should have foreseen would fall on someone like her. Wrong to the unknown package holder, he wrote, was not wrong to the woman standing at the far end of the platform. She was outside the “orbit of danger.”
That is proximate cause.
It is the doctrine that gives judges permission to say: yes, you caused this. And yes, the law still stops here.
The reason the doctrine exists is uncomfortable, and it is honest. Cause-in-fact runs forever. Every event has a hundred causes stretching back to the beginning of the day, the year, the century. Without a stopping rule, tort law becomes a search for the first person in a chain of events long enough to reach any tragedy. Proximate cause is the stopping rule. It draws a line and says: the defendant is responsible only for the harm that was, in some real sense, within the zone of what could have been anticipated. Beyond that line, however tragic the outcome, the law goes quiet.
For the plaintiff, the move is to shrink the distance. The harm was foreseeable. The victim was foreseeable. The type of injury was foreseeable. If you can put your client inside the orbit of danger, cause-in-fact does the rest.
For the defense, the move is to stretch it. The harm was bizarre. The victim was accidental. The chain was too long, the intervening events too strange, the plaintiff too far from anything the defendant could have expected. Every unforeseen actor between the negligence and the injury is a wedge widening the distance.
The move for the rest of us: when you read that a case was dismissed even though the defendant “clearly caused” the harm, look for the words proximate cause. They mean the court agreed the domino line was real. And drew the line anyway.
One word, two technically, and a hundred years of tort law lives inside it.
