Upon a review of the record, we cannot say that the trial judge erred in denying the defendant’s motion for a new trial (Mass.R.Crim.P. 30[b],
It is hornbook law that a motion for a new trial is directed to the sound discretion of the trial judge, informed by the statutory standard.
Davis
v.
Boston Elev. Ry.,
What removes this case from the ordinary is that the motion judge writes of a particular item of evidence offered in support of the motion, “It is apparent to the [cjourt that this evidence may have had a significant effect on the jury if they had heard it.” The evidence to which the judge refers was an affidavit by James McGarry, the police chief of Sheffield, whom the prosecution had placed on the stand as a rebuttal witness. The defendant Markham was convicted by a jury on charges of assault and battery and assault with intent to rape. His defense was an alibi: that at the very time the incident took place in Great Barrington he was in fact in Sheffield and was seen there with his car, which had become mired in a soft shoulder. The heart of the prosecution’s case was an identification of the defendant by the victim as her assailant. That identification was unusually strong in that the defendant was deaf and mute and because the victim had seen him some fifteen minutes before the assault gesturing to a mutual acquaintance in a corridor leading to her apartment.
At trial, Chief McGarry had testified that at a time when several alibi witnesses said they had seen the defendant stuck in the mud with his car on Home Road in Sheffield, he had made a two mile sweep of that road and had seen neither the defendant nor his car. Chief McGarry’s testimony was potent support for the prosecution’s argument that the alibi witnesses must have been mistaken about when they *653 saw the defendant. In an affidavit accompanying the motion for a new trial, Chief McGarry said that he had in fact driven north on Home Road only to the Landis Place, a point which was seven-tenths of a mile short of where the alibi witnesses had placed the defendant.
Under Mass.R.Crim.P. 30(b), a trial judge “may grant a new trial at any time if it appears that justice may not have been done.” This language substantially tracks that of G. L. c. 278, § 29, as appearing in St. 1966, c. 301, the statute which prescribed the basis for new trials prior to the effective date (July 1, 1979) of the Massachusetts Rules of Criminal Procedure. Before passage of the 1966 revision of G. L. c. 278, § 29, the inquiry on a motion for a new trial was whether “justice
has
not been done” (emphasis supplied) . Although the 1966 legislation enlarged the grounds upon which a trial court judge might grant a new trial, the standard of appellate review remained the same.
Commonwealth
v.
Stout,
The trial judge decided to discount the importance of Chief McGarry’s changed evidence for two reasons. First, he did not think it was newly discovered evidence because the defense might have cross-examined about exactly how far McGarry drove. We are inclined to think this asked too much of defense counsel, who had no reason to anticipate the McGarry testimony and in the circumstances might well have assumed that cross-examination would be futile if not counterproductive. In this sense, the case is unlike the situations in
Commonwealth
v.
DeChristoforo,
We do not view this as a statement by the judge that on his review of the entire trial and the proffered new evidence he was persuaded that the defendant was guilty. That is
*654
not the proper standard. It is not the judge’s conclusion as to the guilt or innocence of the defendant which determines the decision on a motion for a new trial; rather the question before the judge is whether the new evidence
1
offered creates a substantial risk that a jury exposed to that evidence would have reached a different conclusion. See
Davis
v.
Boston Elev. Ry.,
Since
Davis
was written when the statutory inquiry was whether “justice has not been done” rather than whether “justice may not have been done,” we may conclude that under the standard which now governs, the
Davis
criteria are to be applied with somewhat more generous predisposition. See, e.g.,
Commonwealth
v.
Richardson,
*655 Although the trial judge used language in his findings on several occasions which suggested that he was to be guided by whether he was “convinced” that the jury had reached the correct result, we are satisfied from his analysis of the newly offered evidence that in reaching his decision he was applying the correct standard, i.e., whether the new evidence offered created a substantial risk that a jury exposed to it would have reached a different conclusion. He emphasized the strength of the victim’s identification of the defendant, whom she first saw outside her apartment, later gesturing to her at her window and again in her room when the assault occurred. As we have noted, the defendant’s severe speech impediment caused him to be especially identifiable. The judge also touched on other weaknesses in the defense case. Thus, Chief McGarry’s contribution did not go to the jugular. Indeed there was nothing directly inculpatory about McGarry’s testimony; its significance was limited to casting doubt on some of the defendant’s exculpatory evidence.
Applying the knowledge of the case which he acquired by presiding over the trial, the judge was in the best position to assess the probable impact of the proffered evidence on a jury which heard it together with the other evidence presented.
Commonwealth
v.
Bernier,
We conclude that the judge applied the correct standard and analyzed the potential impact of the new evidence conscientiously.
Order denying motion for new trial affirmed.
Notes
To qualify for consideration as “newly discovered,” the evidence offered must be material, that is, “weighty and of such nature as to its credibility, potency, and pertinency to fundamental issues in the case as to be worthy of careful consideration.”
