delivered the opinion of the court.
By an indictment returned in the District Court of the Second Judicial District of the Territory of Utah, at its May term, 1895 — that being a court- of general jurisdiction — the plaintiff in error and one Jack Moore were charged with the crime of grand larceny alleged to have been committed March 2, 1895, in Wayne County of that Territory, by unlawfully and feloniously stealing, taking and driving away one calf, the property of Heber Wilson.
. The case was first tried when Utah was a Territory, and by a-jury composed of twelve persons. Both of the defendants were found guilty as charged, and were recommended to the mercy of the court. A new trial hawing been granted, the' case was removed for trial to another county. But it was not again tried until after the admission of Utah'into the Union as a State.
At the second trial the defendant was found guilty. .He moved for a new trial upon the ground among others that the jury that tried him was composed of only eight jurors; whereas by the law in. force at the time of the commission of the alleged offence a lawful jury in his case could not be composed of less than twelve jurors. The application- for a new trial having been overruled, and the accused having been called for sentence, he renewed his objection to the composition of the jury, and moved by counsel that the verdict be set aside and another trial ordered.
This objection was overruled, the accused duly excepting to the action of the court. He was then sentenced to the state prison for the term of three years. The judgment of conviction was affirmed by the Supreme Court of Utah, the court *345 holding that ■ the trial of the accused by a jury composed of' eight persons was' consistent with the Constitution of the United States.-
By the statutes of the Territory o.f. Utah in force at the time of-the-commission of the alleged offence it was provided that a- trial jury in a District Court .should consist of twelve, and in a justice’s court of six, persons, unless the parties to the action-or proceeding, in other than criminal cases, agreed upon ‘ a less number.; that a felony' was a crime punishable with ' death or by imprisonment in the penitentiary, every other crime'being a misdemeanor; that tho stealing of a calf was grand larceny and punishable by confinement in the penitentiary for not less than one riormore than ten years; that no person.should be convicted of a public offence unless b}r the verdict of a jury, accepted and recorded by the court, or upon a plea of guilty, or upon judgment .against- him upon a demurrer, or upon the judgment of a court, a jury having been waived in a criminal action not am'ounting to -a felony; and that issues of fact should be tried by jury,- unless a trial in that mode was waived in criminal cases not- amounting, to a felony by the consent of both parties expressed in. open court and entered in its-minutes. 2 Compiled Laws,-Utah, 1888, §§ 3065, 4380, .4643, 4644, 4790, 4997.
By the constitution of the State of Utah it is" provided :• “ In capital case's the right of trial by jury shall remain .inviolate. In courts of general jurisdiction, except in capital cases, a jury shall consist of eight jurors.- In courts of inferior jurisdiction a jury shall consist of four jurors. In- criminal cases the verdict shall be unanimous.” ■ Art. I, Sec. 10. Also :• “ All' criminaLprosecutions and penal actions which may have arisen or which may arise before the change from a territorial to a state government, and which shall then be pending, shall be' prosecuted to judgment and execution in the name of the State, and in ■ the- court having jurisdiction thereof. All offences committed against the laws of the Territory o.f Utah, •before the change from a territorial'to a state government, and which shall not have been prosecuted before such .change, may be prosecuted in the name and by the authority of the State *346 of Utah, with like effect, as though such change had not taken place, and all penalties incurred shall remain the same, as if this'constitution had not .been adopted.” Art. XXIV, Sec. 6.
As the offence of which the plaintiff in error was convicted was a felony, and as. by the law in force when the crime was committed he could not have been tried by a jury of a less number than twelve jurors, the question is presented whether the provision in the constitution of Utah, providing for a jury of eight persons in courts of general jurisdiction, except in capital cases, can be made applicable to a felony committed within the. limits of the State while it was a Territory, without bringing that provision into conflict with the clause of the • Constitution of the United States prohibiting the passage by any State of an ex post facto law.'
The Constitution of the United States provides.: “ The trial of all crimes, except in cases of impeachment, shall be by jury; and such trial shall be held in the State where the said crimes shall have been committed, but when not committed within any State, the trial shall be at such place or places as the Congress may by law have directed.” Art. HI, Sec. 2. And by. the Sixth Amendment of the Constitution it is declared : “ In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the State and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his. • favor, and to have the assistance of counsel for his defence.”
That the provisions of the Constitution of the United States ' relating to the right of trial by jury in suits at common law ■apply to the Territories of the United States is no longer an open question.

It is equally beyond question that the provisions of the National Constitution relating to trials by jury for crimes and to criminal prosecutions apply to the Territories of the United States.

v.

In
Mormon Church
v.
United States,
Assuming then that the provisions of the Constitution relating to trials for crimes and to criminal prosecutions apply to the Territories of the United States,, the next inquiry is whether the jury referred to in the original Constitution and in the Sixth Amendment is a jury constituted, as it was at common law; of twelve persons, neither more nor less. 2 Hale’s P.'C. 161 ; 1 Chitty’s Cr. Law, 505. This question must be answered in the affirmative. When Magna Charta declared that no freeman'should be deprived of life, etc., “ but by the judgment of-, his peers or by the law of the land,” it referred to a trial by twelve jurors. Those who emigrated to this *350 country frotn England brought with them this great privilege “ as their birthright and inheritance, as a part of that admirable common law which had fenced around and interposed barriers on every side against the approaches of arbitrary power.” 2 Story’s Const. § 1779. In Bacon’s Abridgment, Title Juries, it is said: “ The trial per pais, or by a jury of one’s country, is justly?- esteemed one of the principal excellencies of our Constitution; for what greater security can any person have in his life, liberty or estate, than to be sure of not being divested of, or injured in any of these, without the sense and verdict of twelve honest and impartial men of his neighborhood % And hence we find the common law herein confirmed by Magna Charta.” So, in 1 Hale’s P. C. 33: “ The law of England hath afforded the best method of trial, that is possible, of this and all other matters of fact, namely, by a jury of twelve men all concurring in the same judgment, by the testimony of witnesses viva voce in the presence of the judge and jury, and by the inspection and direction of the judge.” It must consequently be taken that the word “ jury” and the words “ trial by jury ” were placed in the Constitution of the United States with reference to the meaning affixed to them in the law as it was in this country and in England at the time of the adoption of that instrument; and' that when Thompson committed the offence of grand larceny in the Territory of Utah — which was under the complete jurisdiction of the United States for all purposes of government and legislation — the supreme law of the land required that he should be tried by a jury composed of not less than twelve persons. And such was the requirement of the statutes of Utah while it was a Territory.
Was it then competent for the State of Utah, upon its admission into the Union, to do in respect of Thompson’s crime what the United States could not have done while Utah was a Territory, namely, to provide for his trial by a jury of eight persons \ '■
We are of opinion that the State did not acquire upon its admission into, the Union'the power to provide, in respect of felonies committed within its limits while it was a Territory, *351 that they should be tried otherwise than by a jury such as is provided by the Constitution of the United States. When Thompson’s crime was committed, it was his constitutional right to demand that his liberty should not be taken from him except by the joint action of the court and the unanimous verdict of a jury of twelve persons. To hold that a State could deprive him of his liberty by the concurrent action of a court- and eight jurors, would recognize the power of the State not only to do what the United States in respect of Thompson’s crime could not, at any time, have done by legislation, but to take from the accused a substantial right belonging to him when the offence was committed.
It is not necessary to review the numerous cases in which the courts have determined whether particular statutes come within the constitutional prohibition of
ex post facto
laws. It is sufficient now to say that a statute belongs to that class which by its necessary operation and “ in its relation to the offence, or its consequences, alters the situation of the accused to his disadvantage.”
United States
v.
Hall,
Now, Thompson’s crime, when committed, was punishable by the Territory of Utah proceeding in all its legislation under the sanction of and in subordination to.the authority of the United States. The court below substituted, as a basis' of judgment and sentence to imprisonment in the penitentiary, the unanimous verdict of eight jurors in place of a unanimous verdict of twelve. It cannot. therefore be said that the constitution of Utah, when applied to Thompson’s case, did not deprive him of á substantial right involved in his liberty, and *353 did not materially alter the situation to his disadvantage.' If, in respect to felonies committed in Utah while it was & Territory, it was competent for the State to- prescribe a jury of eight persons, it could just as well have prescribed a jury of four or two, and, perhaps, have dispensed altogether with a jury, and provided for a trial before a single judge.
The Supreme Court of Utah held that this case came within the principles announced by it in
State
v Bates,
It is said that the accused did not object, until after verdict, to a trial jury composed of eight persons, and therefore he should not be heard to say that his-trial by such a jury was in violation of his constitutional rights. It is sufficient to say that it was not in the power of one accused of felony, by consent expressly given or by his silence, to authorize a jury of only eight persons to pass upon the question of his guilt. The law in force, when this crime was committed, did not permit any tribunal to deprive him of his -liberty, except, one constituted of a court and a jury of twelve persons. In the case of Hopt v. Utah, above cited, the question arose whether *354 the right of an accused, charged with felony, to be present before triers of challenges to jurors was waived by his failure to object to their retirement from the court room, or to their trial of the several challenges in his absence. The court said : “ We are of opinion that it was not within the power of the accused or his counsel to dispense with the statutory require- ■ ment as to his personal presence at the trial. The argument to the contrary necessarily proceeds upon the ground that he alone is concerned as to the mode by which he may be deprived of his life or liberty, and that the chief object bf the prosecution is to punish him for the crime charged. But this is a mistaken view as well of the relations which the accused holds to the public as of the end of human punishment. The natural life, says Blackstone, cannot legally be disposed of or destroyed by any individual, neither by the person himself, nor by any other of his fellow creatures, merely upon their own authority. 1 Bl. Com. 133. The public has an interest in his life and'liberty. Neither can be lawfully taken except in the mode prescribed by law. That which the law makes essential in proceedings involving the deprivation, of life or liberty cannot be dispensed with or affected by the consent of the accused, much less by his mere failure, when on trial and in custody, to object to unauthorized methods. The great end of punishment is not the expiation or atonement of the offence committed, but the prevention of future offences of the same kind. 4 Bl. Com. 11. Such being the relation which the citizen holds to the public, and the object of punishment for public wrongs, the legislature has deemed it essential to the protection of one whose life or liberty is involved in a prosecution for felony, that he shall be personally present at the trial; that is, at every stage of the trial when his substantial rights may be affected by the proceedings against him. If he be deprived of his life or liberty without being so present, such deprivation would be without that due process of law required by the Constitution.”
If one under trial for a felony the punishment of which is confinement in a penitentiary could not legally consent that the trial proceed in his absence, still less could he assent to be *355 •deprived of bis liberty by a tribunal not authorized by law to determine his guilt.
In our opinion, the provision in the constitution of Utah providing for the trial in courts of general jurisdiction of criminal cases, not capital, by a jury composed of eight persons, is ex post facto in its application to felohies committed before the Territory became 'a State, because, in respect of such •crimes, the Constitution of the United States gave the accused, at the time of the commission of his offence, the right to be tried by a jury of twelve persons, and made it impossible to •deprive him of his liberty except by the unanimous verdict of such a jury.
The judgment is reversed and the cause. is rema/nded for further proceedings not inconsistent with this opi/nion.
