The writ of error in this case questions the judgment of the Supreme Court of New Mexico which affirmed a conviction of the defendant below of the crime of murder in the third degree.
[1] It is assigned as error that the trial court charged the jury that “a reasonable doubt is one for which a reason could be given based on the evidence or want of evidence in the case.” Because this instruction destroys the rule of reasonable doubt, substitutes for a reasonable doubt a demonstrable doubt, logically and conclusively sustained by the evidence or the want of it, and plaices too heavy a burden on the defendant, it is error. A discussion of the question here presented may be found in the opinion of this court in Pettine v. Territory of New Mexico, 201 Fed. 489, 119 C. C. A., which is handed down herewith. In the case at bar the Supreme Court of New Mexico conceded the existence of the error in the charge of the trial court, but declined to reverse the judgment of conviction on the ground that the error was not prejudicial because in its opinion the testimony of the defendant himself excluded the possibility of a reasonable doubt of bis guilt. Territory v. Ayer, 15 N. M. 581, 113 Pac. 604, 607. Two of the justices of that court, however, dissented from this conclusion on the ground that the question whether or not a part or all of the evidence overcame the presumption of the defendant’s innocence in this case and established his guilt beyond a reasonable doubt wais a question for the jury, and not for that court.
The legal presumption is that error produces prejudice, arid it is only when it appears so clear as to be beyond doubt that the error challenged did not prejudice, and could not have prejudiced, the complaining party, that the rule that error without prejudice is no ground for reversal is applicable.
The judgment below must therefore be reversed, and the case must be remanded, with directions to set aside the verdict and grant a new trial, and it is so ordered.
