The defendant, Joseph N. Callahan, was indicted on April 12, 1976, for the murder of one Marian Reichle, and on December 21, 1976, he was convicted of her murder in the first degree. The defendant appeals under G. L. c. 278, §§ 33A-33G, and seeks a new trial based on the following alleged errors by the trial judge in: (1) admitting in evidence statements made by the defendant during a court-ordered psychiatric examination; (2) instructing the jury on the consequences of a verdict of not guilty by reason of insanity; (3) instructing the jury on the burden of proof; *822 (4) permitting certain prejudicial statements by the prosecutor in his closing argument; and (5) prematurely delivering to the jury a so called Allen or Tuey-Rodriquez charge. The defendant acknowledges that no objections or exceptions were taken on any of these points, but seeks relief based on the court’s powers under Gi L. c. 278, § 33E, to guard against the substantial risk of a miscarriage of justice. See Commonwealth v. Cole, ante 30, 36-37 (1980).
We find no error in any of the points raised by the defendant. However, in accordance with our duty to review the record independently, we find error which requires the granting of a new trial in the portion of the judge’s charge to the jury relating to the “presumption” of malice aforethought arising from the intentional use of a deadly weapon.
1. Instruction to the jury on the “presumption” of malice. Thе judge instructed the jury that a presumption “ is not evidence, but it’s a rule which governs until sufficient evidence appears to the contrary.” He later stated, concerning inferences, that the “jury is entitled to draw inferences which naturally, reasonably and logically result from facts found” by them beyond a reasonable doubt, and gave examples of such inferences.
The judge went on to instruct the jury on the elements of the crime of murder, including the element of malice. After properly defining malice, and distinguishing between “active” malice and malice “implied by the unlawful, unjustified killing itself,” he went on to instruct the jury that a presumption of malice arises from the intentional use of a deadly weapon, as reprinted below. 1
*823
This instruction is defective in two respects. First, the instruction has the effect of imposing a mandatory presumption of malice arising from the use of a deadly weapon, counter to the teaching of
Mullaney
v.
Wilbur,
It is well settled that the existence of malice may be inferred from the intentional use of a deadly weapon.
Commonwealth
v.
Campbell,
In
Gibson
v.
Commonwealth,
Most recently, in Commonwealth v. Medina, ante 565, 577-579 (1980), we examined a charge which included a single use of the word “presumption” in describing the inference of malice, pursuant to our duty under G. L. c. 278, § 33E. We termed the use of the word “regrettable,” id. at 577, but found that error was avoided beсause the charge as a whole made clear the Commonwealth’s burden of proof. In that case, as in McInerney, the word “presumption” was used in company with, and synonymously with, the word “inference,” and the latter word was properly defined. It was therefore left clear, we held, that the Commonwealth bore the burden of proving malice, “and the defendant had no onus to disprove it.” Id. at 578.
In the charge in the present case the word “presumption” was defined as having a mandatory effect, while “inferences” were described as permissibly drawn from the facts proved. The charge concerning the inference of malice used some form of the word “presumption” six times, and the word “inference” not at all. It was clearly stated thаt unless some evidence were introduced to the contrary, presumably by the defendant, the “implication” of malice was required to be drawn from the intentional use of a deadly weapon. This language clearly reflects the shifting of some burden
*825
onto the defendant. See
Connolly
v.
Commonwealth,
As to the second point, in the footnote cited above in
Commonwealth
v.
Collins,
This case was tried in December, 1976, well after the decisions in
Mullaney
v.
Wilbur
and
Commonwealth
v.
Rodriguez,
and the standard we apply to the charge is accordingly stricter than that applied to cases tried before those decisions.
Connolly, supra
at 530.
Commonwealth
v.
Stokes,
Because we order a new trial on the grounds stated above, we need not reach those issues raised by the defendant which are unlikely to arise again at the new trial. These include the other alleged defects in the instruction on burden of proof, the allegedly prejudicial statements by the prosecutor in closing argument, and the alleged premature dеlivery of the
Rodriguez
charge. The statements made by the defendant to Dr. Stephen G. Cronin in the course of the latter’s examination of him by court order under G. L. c. 123, § 15, should be treated as far as possible in accordance with our decision in
Blaisdell
v.
Commonwealth,
2.
Instructions to the jury on the consequences of a verdict of not guilty by reason of insanity.
The defendant argues, based оn the decision of this court in
Commonwealth
v.
Mutina,
*827 The first contention is answered by the statement in Mutina that “[o]n balance . . . we believe it is best to entrust jurors with a knowledge of the consequences of a verdict of not guilty by reason of insanity.” Mutina, supra at 821. 3 The statement in that decision that a defendant who requests such an instruction is “entitled” to one, and that the instruction “shall also be given on the request of the jury, if the defendant does not object thereto,” does not limit the giving of the instruction to those circumstances, nor prevent a judge from giving such an instruction on his own initiative, where the issue is fairly raised and the defendant does not object. Id. at 823 n.12. The defendant’s counsel at trial made it clear that he expected the judge to сharge the jury in accordance with Mutina. Such a charge was given, and was not objected to. There was no error.
We find no error in the content of the judge’s charge on this issue. The
Mutina
case does not prescribe any particular wording to be used in instructing a jury on this subject, but requires that in certain circumstances an instruction be given which fairly informs the jury of the possible consequences of a verdict of not guilty by reason of insanity. These consequences are governed by the procеdures set forth in G. L. c. 123, § 16, which permits an initial observation period, a motion for commitment by the district attorney, a possible initial period of commitment, and, upon reevaluation, possible additional periods of commitment. See
Commonwealth
v.
Killelea,
It is not neсessary that a judge refer in his charge to the specific time periods set forth in the statute. He cannot, of course, predict the outcome or the ultimate length of com
*828
mitment in a particular case, since this will depend on the еvidence presented at the time of periodic re-evaluations of a committed person.
Commonwealth
v.
McColl,
Judgment reversed.
Verdict set aside.
Notes
“ Our Supreme Court has said that where the killing is caused by the intentional use of a deadly weapon, there arises the presumption of malice aforethought, as that term has been used and understood in this state. The implication of malice arises in every case of intеntional homicide. Where the fact of killing is proved by satisfactory evidence and there are no circumstances disclosed tending to show justification or excuse, there is nothing to rebut the natural presumption of malice. This rule is founded on the plain and obvious principle that a person must be presumed to intend to do that which he voluntarily and wilfully does in fact do, and that he must intend all the natural, probable and usual consequences of his own *823 act. Therefore, when one рerson assails another violently with a dangerous weapon likely to kill and which does in fact destroy the life of the party assailed, the natural presumption is that he intended death or great bodily harm; and as there can be no presumptiоn of any motive or legal excuse for such a cruel act, the consequences follow that in the absence of all proof to the contrary there is nothing to rebut the presumption of malice.”
We note that counsel on this appeal was not trial counsel.
