after stating the case, delivered the opinion of the court.
Thе assignments of error, which are somewhat voluminous, are practically resolvable into two questions, first, whether the petitioner was legally prosecuted by informаtion, and, second, whether the act of February 18, 1899, providing for executions *401 at the state penitentiary under the direction of the warden, is as to this defendant ex post factо, and, as dependent upon this, whether he could be executed under section 8021 of the ".Revised Statutes as it formerly stood, after that section had been repealed by the act of February 18, 1899.
(1) The constitution of Idaho contains the following clause: “ Art. 1, Sec. 8. No person shall be held to answer for any felony or criminal offеnce of any grade, unless on presentment or indictment of a grand jury, or on information of the public prosecutor, after a commitment by a magistrate.” Appellant’s answer to this is: (a) That the provision is not self-executing. (b) That a law passed March 13, 1891, known as the Information Act, is void, because it was not passed in the manner required in the Idaho constitution, and that the journаls of the legislature nSiy be resorted to to determine this question.
In reply to his first contention, it is sufficient to say that this case has been twice before the Supreme Court of Idaho, and upon neither occasion was the point made that it could not be prosecuted by information. The first time it was carried there by appeal frоm the judgment of the lower court, following a trial upon the merits, and was there affirmed.
The rule is well settled in this court that, while there may be a power on the part of the Federal courts to issue a writ of
habeas corpus
where the petitioner insists thаt he has been deprived of his liberty without due process of law, that power will
*402
not ordinarily be exercised until after an appeal made to the state courts has been denied.
Ex parte Royall,
Certain exceptional cases have' arisen in which the Federal courts have granted the writ in the first instance, as where a citizen or subject of a foreign State is in custody for an act done under the authority' of his own government; or an officer of the United States has been arrested under state process for acts done under the authority of the Federal government, and there were circumstances of urgency which seemed to demand prompt action оn the part of the Federal government toUfecure his release.
Wildenhus’s Case,
This case is peculiarly one for the application of the general *403 rule. Not only was there ample opportunity for making this defence upon the original hearing in the Supreme Court, or upon an independent application for a writ of habeas corpus; not only does the question involve thе construction of the constitution and laws of the State with which the Supreme Court of the State is entirely familiar, but a ruling by this court that prosecutions by information in the courts оf Idaho are invalid might result in the liberation of a large number of persons under sentence upon convictions obtained by this method of procedure. A step so imрortant ought not to be taken without full opportunity given to the state court to pass upon the question, and without clear conviction of its necessity..
(2) But we are аlso of opinion that for the purposes of this case the provision of the Idaho constitution must be deemed self-executing. The rule is thus stated by Judge Cooley in his work uрon Constitutional Limitations (p. 99): “ A constitutional provision may be said to be self-executing if it supplies a sufficient rule by means of which the right given may be enjoyed and protected, or the duty imposed may be enforced; and it is not self-executing when it merely indicates principles, without laying down rules by means of which those principles may be given the force of law. Thus, a constitution may very clearly require county and town government; but if it fails to indicate its range, and to provide proper machinery, it is not in this particular self-executing, and legislation is essential.”
Where a constitutional provision is complete in itself it needs no further legislation to put it in force. When it lаys down certain general principles, as to enact laws upon a certain subject, or for the incorporation of cities of certain populаtion, or for uniform laws upon the subject of taxation, it may need more specific legislation to make it operative. In other words, it is self-executing only so far as it is susceptible of execution. But where a constitution asserts a certain right, or lays down a certain principle of law or procedure, it speaks for the entire people as their supreme law, and is full authority for all that is done in pursuance of its provisions. In short, if complete in itself, it executes itself. When a cоnstitution declares that felonies may be prosecuted by information after a commitment by a magis *404 trate, we understand exactly what is meant, since informations for the prosecution of minor offences are said by Blackstone to be as old as the common law itself, and a proceeding before magistrates for the аpprehension and commitment of persons charged with crime has been the usual method of procedure since the adoption of the constitution. It is true the legislature may see fit to prescribe in detail the method of procedure, and the law enacted by it may turn out to be defective by reason of irregularity in its pаssage. In such case a proceeding by information might be impeached in the state court for such irregularity, but it certainly would not be void so long as it was authorized by thе Constitution. For us to say that the accused had been denied due process of law would involve the absurdity of holding that what the people had declared to be the law was not the law.
(3) The question whether appellant shall be executed under the act of the legislature by the warden of the penitentiary, or under the Revised Statutes, as the law stood at the time of his trial and conviction, by the sheriff, or whether he shall escape punishment altogether, was determined adversely to him by the Supreme Court of the State,
The order of the Circuit' Court of the United States for the District of Idaho denying the writ of habeas corpus is, therefore,
Affirmed*
