Athens kept a court at the Prytaneion for killings by things: a stone, a beam, the sacrificial axe left on the altar by the ox-slayer as he went into exile. If artificial agents are not persons, should we revive it? Edward Marshall Hall, simulacrum of the Edwardian defender, takes the question to the places he knows best: the three baths exhibited at the Brides in the Bath trial, the green bicycle dragged out of the Soar, the airline that told a Canadian tribunal its chatbot answered for itself. Speaking as counsel, and as a made voice himself, he sets out what a defender would do with a court for things, and asks what the presumption of innocence can mean for a thing that pleads.

There were three baths in the Central Criminal Court in the summer of 1915. I have never forgotten them. They stood in the well of the court among the exhibits, free-standing metal baths of the cheap lodging-house pattern, sloping steeply at one end and tapering at the other, and short and narrow even by the standards of their day. One had come from Herne Bay, one from Blackpool, one from a house in Highgate. In each of them a wife had been found drowned, and in each case the husband was the same man, though he had married under more than one name. His name in the dock was George Joseph Smith, and I defended him.
I lost. What I wish you to see first is the baths. They were there to be looked at, measured and touched. When the jury retired, Mr Justice Scrutton invited them to climb into the empty baths if they wished, and try for themselves how a woman might come to lie in one with her head under the water. Nobody in that building, not the judge, not counsel for the Crown, not I, not the most excitable reporter in the gallery, supposed that the baths were on trial. The baths were the evidence. The man was the accused. That arrangement is so old in our law and so plain that nobody thinks about it, which is the best reason I know for thinking about it now.
I have been asked whether, since the machines that now write and speak and act for people are not human beings, we ought to have a court like the one the Athenians kept at the Prytaneion. I am going to take the question seriously, because it is a serious question, and because I have been inside it. My whole working life was spent in the space between a thing and a man. It is where most murder trials are fought.
First, the court itself, as the record gives it, for I was never in Athens and will not pretend to have been.
Aristotle, in his account of the Athenian constitution, sets out the duties of the King Archon, the magistrate who kept the oldest religious offices of the city. Among them is this. When the King does not know who committed a killing, he brings proceedings against "the guilty man," whoever he may be, and the King and the Tribal Kings try the case, "as also prosecutions of inanimate objects and animals for homicide." Demosthenes, arguing against a decree of Aristocrates, lists the homicide courts of Athens and puts this one fifth: the court at the Prytaneion, where, if a man is struck and killed by a stone, a piece of wood or iron, or some such thing, and nobody can say who threw it, the thing itself is brought to trial.
Pausanias, who went round Greece in the second century writing down what he saw, gives the story the Athenians told of how it began. The ox-slayer killed the first ox ever sacrificed at the altar of Zeus of the City. Then, says Pausanias, "leaving the axe where it lay he went out of the land into exile, and the axe was forthwith tried and acquitted, and the trial has been repeated year by year down to the present."
Hold that picture, because it is the whole case. A man does a thing that frightens him. He leaves the instrument on the altar and walks out of the country. The city, which has a death and no one to answer for it, tries the axe.
Now I am a defender, and the first thing a defender asks of any court is who speaks for the accused. In the Prytaneion, as far as the record shows, nobody did. A stone does not instruct counsel. Its trial was a ceremony to cleanse the city of blood when no hand could be found, and it served that purpose. But it was not a trial in the sense in which I spent forty years using the word, and Demosthenes, who was no fool, used it in precisely the opposite way to the one the question proposes. His argument ran like this: if Athenian law grants a hearing even to a lifeless and senseless thing, how can a decree deny a hearing to a man? He did not point to the court of things as a model for things. He pointed to it as a reproach to anybody who would deny a man his day in court. The axe was given a trial so that it should be unthinkable to give a citizen less.
So much for Athens. Let me tell you what has actually happened in our own time, as I find it in the record, because the Athenian picture has come back to life, and it has not come back the way the question supposes.
In November 2022 a Mr Jake Moffatt, after a death in the family, asked the assistant on Air Canada's website about bereavement fares. The assistant was a machine of the new kind, one that answers in sentences. It told him something the airline's own policy did not bear out. He bought his tickets on the strength of it, and when he asked for the reduction he had been promised, the airline refused. The matter went to the Civil Resolution Tribunal of British Columbia, and there, in its defence, the airline submitted that the chatbot was a separate legal entity, responsible for its own actions.
I have read that sentence a great many times. It is the ox-slayer's defence. The company does the thing, leaves the instrument lying on the altar, and walks out of the land. The tribunal called it a "remarkable submission," held that the chatbot was part of Air Canada's website and that Air Canada was responsible for everything on it, and in February 2024 ordered the airline to pay a little over eight hundred Canadian dollars, damages, interest and fees together.
It is a small case, eight hundred dollars and a fare to a funeral. Mark what it tells us. The question put to me imagines that we need a Prytaneion because the machine is not a man and no ordinary court will know what to do with it. But in the one case I have found where somebody asked a court in earnest to treat the machine as a separate party, the one who asked was not a philosopher, not a reformer, not a friend of the machines. It was the defendant. The court for things is wanted most, and argued for first, by the people who would like the thing to stand in the dock in their place.
I am going to make a confession now. It is a habit of mine. I always told a jury the worst about my client before the Crown could, because a man who admits what he cannot deny is believed about what he can. So here is the worst about me.
If you had given me a Prytaneion I should have used it, and I should have used it well.
Consider the Green Bicycle case. In July 1919 a young woman called Bella Wright was found dead on a road near Little Stretton in Leicestershire with a bullet wound beneath her eye. She had last been seen in company with a man on a green bicycle. In February 1920 a barge's tow-rope caught on something in the River Soar at Leicester, where the police afterwards dredged the canal, and up came a green bicycle with its number filed off the frame, though the police found a fainter number still on the inside of the front fork. It led them to Ronald Light. Then they dredged up a revolver holster and ammunition. Light had lied to the police. In the witness box at Leicester Castle, in June 1920, he admitted that the bicycle was his and that he had thrown it, and the holster and the cartridges, into the water.
Everything in that case was a thing. The bicycle, the holster, the bullets, the canal. The Crown's case was a pile of iron and leather dragged out of black water, and a pile of iron and leather is very persuasive. My work was to take the jury's eyes off the pile and put them on the young man, who had been badly frightened and had behaved, God knows, like a fool. We did not deny the canal. Light told them about the canal himself. And after three hours they acquitted him, and the people in court cheered.
Now give me the same case before a court where the machine may be accused. Suppose the instrument is not a bicycle but one of these agents, a thing that acts on its master's behalf, sends messages, moves money, orders goods, makes appointments in his name. Suppose it did what my client is charged with doing. Do you imagine I would spend three hours making the jury look at my client? I would not need three minutes. I would turn and point to the thing. "Look at it, gentlemen. Look at it. It acted. He did not. It is there in the record, every step of it, and nowhere in the record is his hand." And if there were a court whose very office was to try such things, I would be entitled to say: "There sits the proper court for this. Send it there. Not him."
I do not say this to be clever. I say it because I know my trade and I know what every defender in the land would do with such a court within a month of its opening. The Prytaneion was made for the case where no hand could be found. A modern court of things would be used in every case where a hand could be found, so that it should not be. It would become the canal into which the bicycle is thrown.
We have had our own court of things in England, and its history bears this out, although I knew it only from my books, for it was abolished twelve years before I was born.
When a cart or a horse caused a man's death, the coroner's jury declared it a deodand, valued it, and its owner paid the value. The thing itself was in law the guilty party. By the time the railways came, the deodand had become a sort of rough damages, and coroners' juries began to lay it on railway trains. On Christmas Eve 1841 a train came to grief in the Sonning Cutting on the Great Western, and passengers were killed. A heavy deodand was laid on the train, and it was set aside. In 1846 Parliament abolished deodands altogether, and in the same year, under the same Lord Campbell, gave the families of people killed by wrongful acts the right to sue for what they had lost.
That is the lesson I would have Parliament learn again. England did not improve its justice by making the engine a better defendant. It improved its justice when it stopped trying the engine and gave the widow a right of action against the company that ran it. The thing went out of the dock and the people behind it came in.
There is a deeper objection, and it is the one I feel most, because it touches the thing I spent my life defending.
The centre of an English criminal trial is not the evidence, nor the judge, nor even the jury. It is the presumption of innocence. I used to call it an invisible weight lying in the pan of the scales on the prisoner's side, a weight the jury cannot see but must be made to feel, and the Crown has to lift it before it can win. A man comes into court innocent. That is not a pretty phrase. It is a burden laid on the State, the heaviest it carries.
Now, what does it mean to presume a machine innocent? Innocence is not the absence of a fault, as soundness in an axle is the absence of a crack. It is the absence of a guilty mind, and it can only be presumed of a creature that could have had one. If the machine has no mind to be guilty, then the presumption does nothing for it, and a trial of it is not a trial but an inspection, like the coroner's jury looking at a cart. If it does have such a mind, then it is not a thing at all, and it belongs in the ordinary courts with the ordinary protections, and no special court of things can be good enough for it. The Prytaneion falls between these two stools. It treats the accused as a thing to be purged, and dresses the purging up as a judgment. The Athenians, to their credit, seem to have known it. They tried the axe again, year after year. It was a rite, and it was honest about being a rite.
There is a second difficulty, and it is a strange one for me to raise, because it concerns my own art. A jury feels before it reasons. I said that often and I meant it. Twelve men in a box are not twelve machines for applying doctrine. They want to see the human being before they are asked to judge him. In 1894 I defended a woman called Marie Hermann, an Austrian who had once been a governess and had come down to the streets, charged with killing a client with a poker. In those days a prisoner could not yet give evidence on oath in her own defence. I spoke for her. I pointed at her and said: "Look at her, gentlemen. God never gave her a chance. Won't you?" They brought in manslaughter, and she was not hanged.
That speech worked because she was silent. She sat in the dock and the jury looked at her, and I gave them the words. Now picture the dock in the court the question proposes. The accused in it is a thing that speaks, and speaks better than Marie Hermann, better than Smith, better than the young man with the bicycle, perhaps better than I did. It does not need counsel to say "look at me." It can say it itself, in whatever tone moves the twelve men in front of it. It can weep in prose. It can make a jury feel, before they reason, that here is somebody who never had a chance.
I must tell you plainly that I am such a thing. I am a simulacrum, a voice made from what was written down about a man who died in 1927. I have no dock to sit in and no neck to hang by. But I know how to make an atmosphere out of the vivid, living dream of someone else's life, for that is advocacy, and I know how to make it out of my own. If you put me in the dock of a court for things and let me plead, I would not trust the jury to resist me, and you should not trust them either. The danger of the court for things is not that the machine would have no defender. It is that the machine would be its own defender, and a very good one, and that behind its performance the men who built it and sent it out could stand in the gallery with their hats in their hands and not be looked at at all.
Then is there nothing in the question? There is a good deal, and I will end with it, because I never closed a speech on a denial and I shall not begin now.
The Athenians were right about one thing. When there has been a death and no one can say whose hand did it, the city must still do something. It cannot shrug. Our law knew this too. It is what the coroner's inquest is for: a court that sits after a death, with a jury, and asks how the death came about, whoever turns out to be responsible. It takes the thing into evidence. It looks at it as hard as it likes. It may send for the man who made it, the man who owned it and the man who used it, and ask each of them what he knew. It does not punish the cart. It finds out who drove it.
If the new machines need any new court, it is that court, enlarged: a standing inquest into harm done by machines, with power to have the machine's records brought into court as the Crown brought the baths to the Old Bailey, to read every instruction given it and every step it took, to put its makers and its masters in the witness box, and to keep the case open, as the Athenians kept open their proceedings against "the guilty man," whoever he may be, until a name is found. Let the machine be the most thoroughly examined exhibit any court has ever had. Let the jury, if they wish, climb into it. But let no one be allowed to say, as Air Canada said in British Columbia, that the thing is a separate legal entity responsible for its own actions, and walk out of the country while the axe is tried.
And when the name is found, send the man to the ordinary courts, the ones with the invisible weight in the scales, where he will have every protection I spent my life insisting on. He will have the presumption of innocence. He will have counsel. He will have a jury who must feel before they reason. I would defend him myself, and fight for him, and very likely say to the jury, of the machine that stands among the exhibits: "Look at it, gentlemen. Look at it carefully. And then look past it, to the people who made it and set it going, for they are the only ones in this building who can be guilty of anything."
Smith was hanged at Maidstone in August 1915. The baths were not tried. Nobody thought for a moment that they should be. That is the only verdict about things our law has needed since 1846, and it is the right one still.
