delivered the opinion of the Court:
It is the contention of counsel for appellant that, according to the affidavit of the complaining witness accompanying the requisition stating the facts upon which the prosecution relies, appellant can not be charged with a violation of the confidence game statute above quoted; that the most he is shown to have done was to secure credit upon certain alleged false representations orally made to the complaining witness, and that this only constitutes a crime in Illinois when such representations are made in writing. Hurd’s Rev. Stat. chap. 38, sec. 97. But counsel seem to overlook the fact that appellant is charged with *572the commission of a crime under an express statute of the State of- Illinois. When this appears, further inquiry will not be indulged in habeas corpus proceedings to prevent extradition. It may well be that an indictment based upon this complaint would fall when assailed by a motion in arrest of judgment, or even on demurrer as a defective pleading, but those are all questions for the courts of Illinois. Even this would require us to anticipate the nature of the indictment which may be framed which makes such tests totally inapplicable when a crime, as here, is charged merely by affidavit. As was said in Pierce v. Creecy, 210 U. S. 387, 52 L. ed. 1113, 28 Sup. Ct. Rep. 714: “We are unable to adopt the test suggested by counsel, that an objection, good if taken on arrest of judgment, would be sufficient to show that the indictment is not a charge of crime. Not to speak of the uncertainty of such a test, in view of the varying practice in the different States, there is nothing in principle or authority which supports it. Of course, such a test would be utterly inapplicable to cases of a chargé of crime by affidavit, which was held to be within the Constitution. In Re Strauss, 197 U. S. 324, 49 L. ed. 774, 25 Sup. Ct. Rep. 535. The only safe rule is to abandon entirely the standard to which the indictment must conform, judged as a criminal pleading, and consider only whether it shows satisfactorily that the fugitive has been in fact, however inartificially, charged with crime in the State from which he has fled.”
Under the Constitution, full power resides in each State to control its own criminal procedure. Hence, whether the demand in extradition be based upon an indictment or an inartificial affidavit upon which a warrant has been issued, the extradition amounts to nothing more than a step in securing arrest and detention. Especially is this true where the request from the demanding State is based upon a complaint filed with a committing magistrate, since it implies further proceedings.before the defendant can be brought to trial. “It may be, ahd is true, that in many of the States some further proceeding is, in the higher- grade of offenses at least, necessary before the party can be put upon trial, and that the proceedings before an examin*573iug magistrate are preliminary, and only with a view to the arrest and detention of the alleged criminal; but extradition is a mere proceeding in securing arrest and detention. An extradited defendant is not put on trial upon any writ which is issued for the purposes of extradition, any more than he is upon the warrant which is issued by the justice of the peace directing his arrest.” Ibid. Or as was said in Virginia v. Paul, 148 U. S. 107, 37 L. ed. 386, 13 Sup. Ct. Rep. 536: “Proceedings before a magistrate to commit a person to jail, or to hold him to bail, in order to secure his appearance to answer for a crime or offense, which the magistrate has no jurisdiction himself to try, before the court in which he may be prosecuted and tried, are but preliminary to the prosecution, and are no more a commencement of the prosecution, than is an arrest by an officer without a warrant for a felony committed in his presence.”
But we are not prepared to say, if we were called upon to decide, in view of the decisions of the courts of Illinois, that the circumstances of this case, as stated in the accompanying affidavit of the complaining witness, are sufficient to withdraw it from the operation of the confidence game statute. In Chilson v. People, 224 Ill. 535, 79 N. E. 934, where the defendant entered into a contract of partnership with another for the purpose of purchasing and selling real estate, but where it appeared that the contract was a mere cloak to enable defendant to defraud his partner, it was urged that a prosecution could not be maintained under the confidence game statute, since what occurred amounted to nothing more than a breach of a contract to carry on a legitimate business. In disposing of this contention the court said: “We think it clear that Chilson obtained the confidence of Spooner by representing that he would engage in the contemplated business with Spooner, as his partner, in Milwaukee, and by reason of the confidence so inspired induced Spooner to pay the money to Marden. It is also evident that Chilson did not intend to engage in the business in Milwaukee, and that he falsely pretended he would do so for the purpose of leading Spooner to pay his money for lots, which seem to *574have been of little or no value. Chilson says he has been convicted merely 'for a failure to cany out a plain civil contract or for a breach thereof,’ and that the distinction between the breach of a contract and the false and fraudulent scheme called the confidence game has been disregarded. If plaintiff in error had entered into the contract in good faith his reasoning would be conclusive. Where a contract apparently legal is entered into by one party with the intention of taking no step to carry it out, but with the wrongful intent of causing the other to part with his money without receiving any adequate consideration there-, for, such contract may, and in this case did, become a mere incident of the 'false and fraudulent scheme.’ The ordinary case of 'agreeing to sell the gullible one a gold brick now in the possession of the aged Indian presents a breach of a.contract, and yet counsel would scarcely pretend that it is for that reason any the less a confidence game. The fact that the affair was made to assume the guise of an ordinary business transaction, whereby, as a preliminary, Spooner was required to pay his money for the lots, is without significance. It is the substance, and not the form, that is material. The transaction in question was a 'swindling operation, in which advantage was taken of the confidence reposed by the prosecuting witness in the plaintiff in error,’ — a confidence that Kad been obtained by deceit and .false promises. The case came within the confidence game statute.”
In the present case the fact remains that appellant stands charged in a complaint duly verified by oath, drawn in conformity with the statute, of the offense of having perpetrated a confidence game, and this is sufficient to warrant his removal to the demanding State. Manifestly, the courts of this District will not in a habeas corpus proceeding to prevent extradition assume the jurisdiction which belongs exclusively to the courts of Illinois and determine the sufficiency of the complaint by a construction of the various statutes of that State touching the case. The rule, many times laid down by the courts of this country, both State, and Federal, was again announced by Mr. *575Justice Moody, speaking for the court, in Pierce v. Creecy, supra, as follows:
“This court, in the cases already cited, has said, somewhat vaguely but with as much precision as the subject admits, that the indictment, in order to constitute a sufficient charge of crime to warrant interstate extradition, need show no more than that the accused was substantially charged with crime. . . . If more were required it would impose upon courts, in the trial of writs of habeas corpus, the duty of a critical examination of the laws of States, with whose jurisprudence and criminal procedure they can have only a general acquaintance. Such a duty would be an intolerable burden, certain to lead to errors in decision, irritable to the just pride of the States and fruitful of miscarriages of justice. The duty ought not to be assumed unless it is plainly required by the Constitution, and, in our opinion, there is nothing in the letter or the spirit of that instrument which requires or permits its performance.”
It is sought to parallel this case with the case of Hard v. Splain, ante, 1. In that case, it was sought to remove Hard to the State of Michigan to answer the charge of kidnapping. It appeared from the complaint and the affidavit in support thereof that Hard was in fact charged with kidnapping his own daughter by taking her from the custody of her mother and bringing her into the District of Columbia. An examination of the statutes of Michigan disclosed no law in that State upon which such a charge of crime could be based. Hence, the writ was granted to prevent Hard’s removal upon the sole ground that, because of his relation to his daughter, as disclosed by the record, the daughter not having been placed in the custody of the mother by the decree of a court, he was a person incapable of committing the crime of kidnapping in Michigan in the manner charged. We were not called upon to determine whether Hard had committed an offense under this or that statute of Michigan. It was clear that there was a total absence of any legal basis for the complaint. Here no such question is involved. What we are asked to do is to try the case to the extent of determining which, if any, of several statutes of the demanding *576State may have been violated. This the courts have persistently refused to do.
The judgment is affirmed, with costs.
Affirmed.
