Criminal Law—Burden op Establishing Depense op Insanity—Instructions—Preponderance op Evidence—Reasonable Doubt.— In a criminal prosecution, after the court had correctly instructed the jury that the burden of establishing the defense of insanity rested on the defendant, and that the insanity may be established “by a preponderance of evidence merely,” it was erroneous to further define that phrase as meaning “that degree of evidence which proves to a moral certainty, or, in other words, that degree of proof that produces conviction in an unprejudiced mind, regardless of the number of witnesses from whom it proceeds.” The definition so given was substantially the same as that of “proof beyond a reasonable doubt,” and the instruction in effect erroneously told the jury that it was incumbent on the defendant to establish insanity beyond a reasonable doubt.The defendant, charged with murder in the unlawful killing of one Clarence A. Baker, was convicted of murder in the first degree, and adjudged to suffer death. We have an appeal by him from the judgment.
The only defense was that defendant was insane at the time he killed the deceased. The court correctly instructed the jury, in substance, in view of the settled law of this state, that while it was essential to a conviction that the guilt of the defendant be established to their satisfaction beyond all reasonable doubt except on the single question of insanity, that as to insanity the burden of proof was on defendant, and that it was incumbent on him to show insanity by a preponderance of the evidence before he could be acquitted on that ground. The jury were explicitly and correctly instructed that it was not necessary for defendant to show his insanity beyond all reasonable doubt, but only by a preponderance of evidence, as in civil cases; and also that the proof must be
“Preponderance of the evidence means that degree of evidence which proves to a moral certainty, or, in other words, that degree of proof that produces conviction in an unprejudiced mind, regardless of the number of witnesses from whom it proceeds.”
The court refused to give an instruction requested by defendant reading in part as follows, and being in all other respects a correct statement of the law:
“Then what is the term ‘preponderance of the evidence’? By preponderance of evidence is meant the greater and superior weight of evidence; and if the evidence of insanity preponderates in the slightest degree in favor of the defendant you must find him not guilty.”
Defendant’s main contention on this appeal is that the instruction given was erroneous, and we are satisfied that this contention is well based. It is plain to us that the definition thus given by the court was substantially the same as that of proof beyond a reasonable doubt, and that certainly a jury of laymen could find no possible distinction. It is clear that our law contemplates, as does the law generally, a material distinction between the two terms. Always has it been the established rule in this state that proof of guilt beyond all reasonable doubt is essential to the conviction of one of a crime, while a mere preponderance of evidence is sufficient in a civil case, and this rule is expressly stated in section 2061 of our Code of Civil Procedure. The existence of this distinction was fully recognized by the trial judge in this case, who advised the jury as to the necessity of proof of guilt beyond all reasonable doubt, and that defendant was required to prove his insanity only by a preponderance of evidence. The term “reasonable doubt” was fairly enough defined by him, in accord with the definition thereof given by Chief Justice Shaw in Commonwealth v. Webster, 59 Mass. (5
“It is not mere possible doubt; because everything relating to human affairs, and depending -on moral evidence, is open to some possible or imaginable doubt. It is that state of the case, which, after the entire comparison and consideration of all the evidence, leaves the minds of jurors in that condition that they cannot say they feel an abiding conviction, to a moral .certainty, of the truth of the charge. . . . The evidence must establish the truth of the fact to a reasonable and moral certainty; a certainty that convinces and directs the understanding, and satisfies the reason and judgment, of those who are bound to act conscientiously upon it. ’ ’
In instructing the jury as to the meaning of the term “proof beyond a reasonable doubt,” the trial judge, in line with this definition, expressly told the jury that “moral certainty only is required or that degree of proof which produces conviction in an unprejudiced mind”; and again, that “the evidence must establish the truth of the fact to a reasonable and moral certainty; a certainty that convinces and directs the understanding, and satisfies the reason and judgment of those who are bound to act conscientiously upon it. ’ ’ Clearly, the jury was thus given substantially the same definition of both the terms “preponderance of evidence” and the term “proof beyond a reasonable doubt,” thus making it essential for the defendant to establish his defense of insanity by evidence showing the same to the satisfaction of the jurors beyond a reasonable doubt. That such is the effect of the instruction given is shown by what is said in People v. Wreden, 59 Cal. 393 , and People v. Wells, 145 Cal. 142 , [ 78 Pac. 470 ], where it is held that an instruction declaring that insanity “must be clearly established by satisfactory proof” is the full equivalent of one making it incumbent on a defendant to establish insanity beyond a reasonable doubt.
No such definition of the term “preponderance of the evidence” as that given by the trial judge is sanctioned by the authorities. The term simply means what it says, viz., that the evidence on one side outweighs, preponderates over, is more than, the evidence on the other side, not necessarily in number of witnesses or quantity, but in its effect on those to whom it is addressed. As good a definition as we have found
The error of the learned trial judge in this connection was doubtless induced by certain rather carelessly drawn provisions contained in our Code of Civil Procedure enacted in an attempt to satisfactorily define or declare the degree of proof essential to the establishment of a fact by evidence. (See secs. 1826 and 1835, Code Civ. Proc.) Manifestly these provisions are not in accord with other provisions of law in all
We regard the error thus made as one most substantially affecting the rights of defendant. In effect as we have said, the jury was instructed that he could not be acquitted on the ground of insanity unless he established the fact of insanity to their satisfaction beyond a reasonable doubt. We have carefully examined the evidence in order to determine whether, in view of the provisions of section 4% of article VI
Concurrence
In view of our conclusion on the point discussed, it is unnecessary to consider any other point made for reversal.
We find on an examination of the reporter’s transcript of the proceedings at the trial that the same includes all arguments made by counsel to the court on questions of law arising during the trial. In the aggregate many pages of the transcript are devoted to this use. The incorporation of such arguments in a transcript for use on appeal serves no uséful purpose. To the contrary, it not only impedes the examination of the record by an appellate court, but it also unnecessarily adds to the cost of the transcript to the county. The law does not require the insertion of any such matter in a transcript of the evidence to be used on appeal, and the trial judge should see that such a transcript is not unnecessarily lengthened by the incorporation of superfluous matter.
The judgment is reversed and the cause remanded for a new trial.
Shaw, J., Sloss, J., Melvin, J., Lorigan, J., and Henshaw, J., concurred.
I concur in the foregoing opinion of the chief justice. Section 1835 of the Code of Civil Procedure, like section 1826 of the same code, is dealing exclusively with evidence in criminal cases. The difficulty is entirely removed if to the sentence in section 1835, “Such evidence alone will justify a verdict,” there be added “of conviction.” That these sections have applicability solely to criminal cases is made manifest not only by the history and development of the law governing criminal trials, but from two additional facts, each equally convincing. The one fact is that if those sections were made to apply to trials by jury in civil cases, it is within bounds to say that ninety-nine such cases out of a hundred would necessarily result in perpetual mistrials. The evidence in civil cases upon either side is most rarely of so convincing a character as to produce “moral certainty or conviction,” and if it be only such evidence in a civil case as “will justify a verdict,” then it must result that no verdict can be rendered. As pointed out by the chief justice, this distinction is itself noted by our law in section 2061 of the same code. In subdivision 5 of that section criminal cases and civil eases are put in immediate juxtaposition, and courts are advised to instruct their juries that in civil eases their “decision must be made according to the preponderance of evidence,” while “in criminal eases guilt must be established beyond reasonable doubt.” The second fact, equally conclusive, is shown by the history of these two sections, derived from the notes of the codifiers and commentators. Every word of those notes establishes that the codifiers are dealing with the sufficiency of evidence in criminal cases. Thus, in the note to section 1826 it is said, “The principal difference to be remarked between civil and criminal eases with reference to the modes of proof by direct or circumstantial evidence is, that in the former where civil rights are ascertained, a less degree of probability may be safely adopted as a ground of judgment than in the latter ease which affects life and liberty.” While in the note to section 1835 it is said: “To acquit upon light, trivial, and fanciful suppositions and remote conjectures, is a virtual violation of the juror’s oath, and an offense of great magnitude against the interests of society, directly tending to the disregard of the obligations of a judicial oath, the hindrance and dis
“Even the most direct evidence can produce nothing more than such a high degree of probability as amounts to moral certainty. From the highest degree it may decline, by an infinite number of gradations, until it produces in the mind nothing more than a mere preponderance of assent in favor of the particular fact.
“The distinction between full proof and mere preponderance of evidence is in its application very important. In all criminal cases whatsoever, it is essential to a verdict of condemnation, that the guilt of the accused should be fully proved; neither a mere preponderance of evidence, nor any weight of preponderant evidence, is sufficient for the purpose, unless it generate full belief of the fact to the exclusion of all reasonable doubt.
“But in many cases of a civil nature, where the right is dubious, and the claims of the contesting parties are supported by evidence nearly equipoised,, a mere preponderance of evidence on either side may be sufficient to turn the scale. ’ ’
