The trial of capital cases, under our system of criminal jurisprudence, having always been held before a quorum of the justices of the supreme judicial court, and therefore before the highest court known by our laws, it has heretofore been the practice of this court to consider all questions of law arising in the course of the trial to be definitively settled, and not open as a matter of right to a hearing on a bill of exceptions. Commonwealth v. Buzzell, 16 Pick. 153. Commonwealth v. Knapp, 10 Pick. 477. But the St. of 1859, c. 282, the provisions of which are also now incorporated in Gen. Sts. c. 112, has provided that exceptions may be taken by the defendant in capital cases, to be heard by the full court, as other exceptions to the ruling of the court in matters of law.
This case comes before us on such a bill of exceptions. But it is as a bill of exceptions only that we can consider the questions presented, and the exceptions are only to be sustained upon *299the ground that the rulings excepted to are in law erroneous. As to all matters resting merely in the discretion of the court, whether with reference to the course of proceeding at the trial, or as to granting a new trial, nothing is open upon the bill of exceptions.
The principal question raised here is as to the exclusion of a witness offered to be produced by the defendant, after the evidence had been formally closed on the part of the defence as well as of the government, and the counsel for the prisoner had made his closing argument to the jury, and the attorney general had nearly closed his reply thereto. The reason assigned for offering the evidence at that late stage of the case was, that it was new and material to the defence, and then first came to the knowledge of the prisoner or her counsel.
We suppose that it will be readily conceded that it is the duty of the court to superintend the course of a criminal trial before a jury, to direct the order of proceedings, the period at which testimony shall be introduced, and the evidence shall be closed for the trial, and the case pass to another stage — that of hearing the closing arguments of the counsel and the charge of the judge. That the ordinary mode of conducting trials, by requiring that the evidence for the defence shall be put into the case before the commencement of the closing arguments, is a proper one, may also be assumed. After the counsel for the prisoner have had the fullest opportunity allowed them to introduce their evidence in chief and also in reply, and the court are informed by the counsel for the prisoner that the evidence on the part of the defence is closed, and his closing argument has been made to the jury, and that of the attorney general has proceeded to near its close, the legal right of the prisoner to introduce further evidence to the jury on that trial no longer exists.
That the court may, in the exercise of its discretionary powers, yield to such a motion, we have no doubt. But it is a matter of judicial discretion, to be exercised in view of all the circumstances of the case bearing upon the fact of its being newly discovered evidence, of there being no loches in reference *300to the same, and particularly whether the evidence be of a character so material in its bearing upon the case as to require the court to depart from the ordinary course of proceeding in trials by jury, at the hazard of calling the attention of the jury from the evidence properly introduced, and upon which the argument has been addressed to them. A motion of this character is wholly addressed to the discretion of the court; and their decision thereon is final, and not a matter for exceptions to the ruling as error in matter of law.
If such evidence is excluded for the reason that it was offered at too late a stage of the trial, the prisoner has in such case, as he would have if similar evidence had been discovered after the verdict was returned, the right to petition the court for a new trial upon the ground of newly discovered evidence; and upon such petition opportunity will be granted to show any sufficient grounds for granting the motion. It will be still a matter of discretion, and to be granted or denied as under all the circumstances may be deemed proper.
2. The objections taken to the admission of the statements made by the prisoner to various persons in relation to the cause of the death of Mrs. Wilkins, and the means through which it might have occurred, cannot be sustained. The fact that the prisoner had been interrogated concerning the same matter a.t a different time before a coroner’s jury, and her answers under oath taken in writing, affords no sufficient reason for excluding, as incompetent evidence, other statements made by her at other times.
3. The court properly declined giving the instructions asked by the counsel for the prisoner, “that, on the evidence in the case, the husband of the deceased had an equally strong motive with the prisoner to commit the alleged crime.”
Exceptions overruled.
