Lewis, Pearce, Atwood, and Jeter were convicted,, in the county court of Greene county, of the offense of. riot. Thereupon they petitioned the superior court for the writ of certiorari,, which was granted. On the hearing of the certiorari the judge of the superior court entered an order sustaining it as to three of the petitioners and overruling it as to Lewis; and from this judgment he brings error. In their petition for the writ of certiorari no complaint is made of any specific error of law,’the one error assigned being that there was no evidence to support the verdict;. and upon this one assignment of error the court overruled the certiorari as to the plaintiff in error, but sustained it as to the other three defendants, and, as' to them, remanded the case for another trial.
There is some evidence in the record which tends to show that all of the defendants (or plaintiffs in certiorari) participated in the offense -with which they were charged, and if the-' superior court had seen proper to overrule the certiorari as to all of the petitioners,, or had remanded it for a new trial as to all of them, this court would not have disturbed the judgment. But we are clear that the-judgment sustaining the certiorari as to the three and overruling' *497it as to the remaining one is without legal support. Riot, at common law, required the participation of three or riiore persons with common intent and concert of action in the commission of the offense. Our statute (Penal Code, §354) changes the definition of the common law only by reducing the number who must participate in the offense from three to two persons. In this State, therefore, the statutory offense of riot can not be committed by one person. There must be at least two persons participating in an unlawful act of violence, or any other act in a violent and tumultuous manner, before this offense can .be committed. In other words, it is a joint offense, for which one person alone can not be indicted or convicted. The general rule is that all the persons who participate in the unlawful act must be set forth in the indictment; but it can name one person who acted jointly with' others vhose names are unknown to the grand jurors; and if the evidence shows that the party named, jointly with one or two others whose names are unknown, participated in the unlawful act of violence, or any other act in a violent and tumultuous manner, charged in the indictment, this would be sufficient to convict the one named of the offense. In the accusation in question all of the persons who were charged to have participated in the unlawful act of violence were named, and all were convicted, but the reviewing court, on certiorari, sustained the assignment of error that the verdict was without support of evidence as to three of the defendants, thus leaving only one defendant, in the opinion of the court, guilty of the offense charged, „under the evidence. It was a legal impossibility for this une alone to commit this offense, and the finding of the court is tantamount to a verdict of acquittal as to the three and of conviction as to the one. The Supreme Court, in Martin v. State, 115 Ga. 255 (41 S. E. 576), following a long line of decisions in England and in this country, held that where several persons are indicted for a riot and the proof shows the guilt of only one, all must be acquitted, unless the indictment contain the allegation that the defendant committed the offense of riot sinful cum aliis juratoribus ignotis. In Turpin v. State, 4 Blackf. (Ind.) 72, an indictment was against three persons for riot. There was a verdict of guilty as to one, and of not guilty as to the others. It was held that upon this verdict judgment could not be rendered against the defendant found guilty, though it would have been au*498thorized if the indictment had been against the defendant together with others whose names were unknown. In Eex v. Scott, 3 Burr. 1264, the great English jurist, Lord Mansfield, tersely covers the point now under consideration, .as follows: “Six were indicted; two of them are acquitted; two are dead, untried. The jury have found these two to be guilty of a riot: consequently, it must have been together with those two who have never been tried; as it could not otherwise have been a riot.” And this is the rule laid down by all of the criminal writers and upheld by all the decisions of the courts on this -subject, in England and in this country.
What, we have said above would not apply to a case where there is a severance and a separate trial of each defendant; for then the acquittal of the one first tried would not operate to acquit the others. This under our Penal Code, §969. Rachels v. State, 51 Ga. 375. We therefore conclude that the learned judge of the superior court, for the reasons stated, erred in not sustaining the certiorari as to the plaintiff in error. Judgment reversed.
