This is a petition by the Commonwealth under G. L. c. 211, § 3, for relief from the action of a judge of the Superior Court in allowing the defendant’s motion for *315 new trial under G. L. c. 278, § 29. 1 A single justice of this court denied the Commonwealth relief and ordered the petition dismissed. The case is before us on the Commonwealth’s appeal from the judgment of dismissal. We affirm the judgment.
The defendant, Vernard Cook, was convicted of murder in the first degree and related offenses,
2
by a jury on June 12, 1973, and appealed therefrom to this court. We affirmed his conviction by our opinion in
Commonwealth
v.
Cook,
On December 16, 1976, Cook filed a pro se motion for a new trial, and a judge of the Superior Court appointed new counsel to represent him thereon. On February 28, 1977, the new counsel filed a substitute motion for a new trial, on the grounds of ineffective assistance of counsel, and judicial and prosecutorial overreaching. The judge who had presided over the original trial had retired, so the motion was heard by another judge of the Superior Court (motion judge). Hearings on the motion were held on December 21, 1977, and again on March 2, 1979; the delay between the two hearings being due to the unavailability of a witness. The original trial counsel for Cook and the prosecutor for the Commonwealth testified. On May 14,1979, the motion judge filed Findings, Rulings and Order granting Cook’s motion.
*316 The Commonwealth sought relief from that decision and order by the present petition under G. L. c. 211, § 3. The single justice who heard the petition filed a memorandum in which he “assume[d], without deciding, that the Commonwealth may seek relief under G. L. c. 211, § 3, from the granting of a motion for a new trial,” and ruled that “ [ajlthough the circumstances do not seem to have required the allowance of the motion ... I cannot rule that the allowance . . . was an abuse of discretion.” The Commonwealth is appealing from that decision of the single justice.
After the parties argued before this court, Cook’s counsel filed a “suggestion of mootness,” because Cook had earlier escaped from prison and his whereabouts were still unknown. A fugitive from justice cannot pursue an appeal, because “ [b]y his voluntary act, which renders him unavailable to await the decision of the court, he has waived appellate rights.”
Commonwealth
v.
Rezendes,
The facts forming the basis for the motion for a new trial were, in broad outline, as follows. During Cook’s trial, the prosecutor called to the stand Joseph Andrews, Cook’s co-participant in the crime, whose trial had been severed under the Bruton rule. 3 Andrews testified, but, as to all but innocuous questions, he refused to answer on the ground that his answers might tend to incriminate him. Cook’s trial counsel did not at any point object, except, request a voir dire, or request a jury instruction.
A somewhat more lengthy recapitulation of the Andrews episode is necessary to provide the proper factual context for the ruling of the motion judge. The evidence against Cook at his trial was, as we noted on direct appeal, largely cir *317 cumstantial. Cook, supra at 772. 4 The prosecutor told the jury in his opening statement that Cook and Andrews were alleged to have committed the robbery and murder. Before Andrews was called to the stand, other eyewitnesses had testified that a tall man and a short man participated in the robbery. 5 As soon as Andrews was sworn as a witness but before he took the stand, he said, “I don’t want to say anything.” His own attorney immediately advised him that he had a right to refuse to answer any question the prosecutor might ask. At that point in the trial neither the judge, nor the prosecutor, nor Cook’s trial counsel did anything to explore whether Andrews intended to invoke his privilege against self-incrimination. The judge simply stated: “He may take the stand.” Andrews answered several preliminary questions, including his name, the fact that he was then in custody at Charles Street jail, 6 that he had known Cook for eight or nine years, and that he, Andrews, lived one block from Humboldt Avenue. An eyewitness to the escape had earlier testified that at some time after the robbery he identified the escape car which was then parked on Humboldt Avenue.
When the prosecutor asked Andrews, “Did you see the defendant back on December 20th, 1972” (the date of the robbery), Andrews pleaded the Fifth Amendment and refused to answer on the ground that he might incriminate himself. He gave the same answer when asked whether or not Vernard Cook was the owner of an automobile during the month of December, 1972.
*318 When asked if he knew Sergeant Whalen (to whom he had made a confession), Andrews replied that he had seen him before. The prosecutor then asked if Andrews had ever spoken to Whalen, and Andrews invoked the privilege against self-incrimination. After seyeral further questions, in response to many of which Andrews invoked the same privilege, the prosecutor showed Andrews “this piece of paper” and asked him to read it to himself. He next asked Andrews if he had read enough of the document to recognize it, and Andrews answered in the affirmative. The prosecutor asked if the paper was “a stenographic copy of the statement that you gave to Sergeant Whalen,” whereupon Andrews again invoked the same privilege. Direct examination then ceased. Cook’s trial counsel asked one question (which the motion judge in his findings characterized as “meaningless”): “Sir, have you ever seen or talked to me?” The witness answered that he had not.
The evidence presented at the hearing on the motion for new trial revealed that there had been preliminary negotiations before Cook’s trial for a plea arrangement for Andrews. Both the Cook and the Andrews prosecutions were being handled by the same assistant district attorney. The prosecutor testified that he had a strong case of murder in the first degree against Andrews including a confession made after full Miranda warnings, and that he had offered to accept a plea to murder in the second degree from him in exchange for his testimony against Cook. No agreement was ever reached, however, and when the prosecutor called Andrews to testify at the Cook trial, he did not know whether Andrews would testify fully or invoke his privilege. Andrews’ attorney testified that he suggested to the prosecutor that he call Andrews. Cook’s trial counsel testified that he had failed to take any action regarding the Andrews episode because he was unaware at the time of any legal basis for doing so.
The contents of Andrews’ confession never reached the jury, so there was no per se violation of
Bruton, supra,

Propriety of review under G. L. c. 211,
§
3.
General Laws c. 211, § 3, as amended through St. 1973, c. 1114, § 44, provides in pertinent part: “The supreme judicial court shall have general superintendence of all courts of inferior jurisdiction to correct and prevent errors and abuses therein if no other remedy is expressly provided . . . .” The order of the Superior Court judge is not appealable under G. L. c. 278, § 28E, governing interlocutory appeals.
Commonwealth
v.
McCarthy,
The fact that the Commonwealth has no other remedy does not make c. 211, § 3, review automatic, however. We have rarely allowed Commonwealth appeals of interlocutory matters under our supervisory powers. See

Standard of review.
The motion judge granted the motion for new trial pursuant to his power under G. L. c. 278, § 29, as amended through St. 1966, c. 301.*

A motion for new trial is generally a matter for the sound discretion of the trial judge.
Earl
v.
Commonwealth,
The standard of review under G. L. c. 211, § 3, of the exercise of judicial discretion in granting a new trial under G. L. c. 278, § 29, is whether the judge acted arbitrarily, frivolously, or contrary to law. McCarthy, supra at 415 & n.6. Furthermore, absent an abuse of discretion by the single justice in denying relief under G. L. c. 211, § 3, the Commonwealth can have no relief from the full court. See Cefalu v. Globe Newspaper Co., 377 Mass. 907 (1979).
3. Grant of a new trial. Before discussing the merits of the motion judge’s ruling, we wish to make clear that the validity of Andrews’ exercise of his privilege against self-incrimination is not before us, and we intimate no opinion thereon. Additionally, in this court, Cook explicitly waived his claim of prosecutorial misconduct at the trial, and we therefore make no attempt to analyze the actions or motives of the prosecutor. Cook relies on ineffective assistance of counsel and the denial of confrontation in support of his claim that the motion judge did not act arbitrarily in granting his motion.
The question whether Cook was deprived of effective assistance of counsel at trial with regard to the Andrews epi
*322
sode turns on whether his trial counsel’s inattention, negligence, or ignorance affected Cook’s trial in such a way and to such an extent as to prejudice his defense. See

v.
Rondeau,
In
Bruton
v.
United States,
In
Douglas
v.
Alabama,
The leading case concerning the situation before us is Namet v. United States, 373 U.S. 179 (1963). Two alleged coparticipants who had pleaded guilty to gambling charges were called to testify against Namet, an alleged participant *323 with the first two. The presiding judge held a conference out of the jury’s hearing and ruled that the witnesses had a limited privilege as to dealings with third persons but not as to their own gambling activities, because they had already pleaded guilty (but could be subject to further charges of bribery or conspiracy). The Supreme Court upheld this procedure, but noted certain facts which distinguish Namet from the present case. In Namet, the government’s closing argument included no reference to the refusal to testify, the jury were not told that the coparticipants were arrested or charged together with Namet, and the judge fully instructed the jury not to draw any adverse inferences about Namet’s guilt from the refusal of the witnesses to testify. See Namet, supra at 181-184. Furthermore, Namet’s attorney objected, and obtained a bench conference resulting in a ruling on the validity of the witnesses’ privilege, a procedure not followed by Cook’s attorney.
Although the Court found no error in Namet, it established the test for such cases as the present one: “error may be based upon a concept of prosecutorial misconduct, when the Government makes a conscious and flagrant attempt to build its case out of inferences arising from use of the testimonial privilege . . . [or] in the circumstances of a given case, inferences from a witness’ refusal to answer [may have] added critical weight to the prosecution’s case in a form not subject to cross-examination, and thus [may] unfairly [have] prejudiced the defendant.” Id. at 186-187. 14
We have applied the
Namet
test in this Commonwealth. See

Martin,
We have affirmed convictions where coparticipants and other witnesses had invoked their Fifth Amendment privilege, but those cases are distinguishable on their facts from the present case. See

General Laws c. 278, § 29, was replaced by Mass. R. Crim. P. 30,
Armed robbery, armed assault with intent to rob, and unlawfully carrying a pistol on his person.
Bruton
v.
United States,
None of the eyewitnesses could identify Cook. He was linked to the crime through possession and operation of the escape vehicle, possession of money and a gun, attempted flight when the police came to his home, and inconsistent statements to the police.
Commonwealth
v.
Cook,
One eyewitness estimated the height of the taller man as 6'1" or 6'2", and the shorter man as 5'7".
Although the jury was never told that Andrews was formally charged with a crime, the fact that he was being held at Charles Street jail may have alerted some jurors that he was awaiting trial.
Under Mass. R. Crim. P. 30 (c) (8),
General Laws c. 278, § 33E, reads in pertinent part: “If any motion is filed in the superior court after rescript, no appeal shall lie from the decision of that court upon such motion unless the appeal is allowed by a single justice of the supreme judicial court on the ground that it presents a new and substantial question which ought to be determined by the full court.”
In the one case where we considered a Commonwealth appeal of the grant of a motion for a new trial, we stated that we “assume without deciding that, under some circumstances [vacating a judgment of guilty] may be the type of interlocutory ruling which results in ‘irremediable’ prejudice, and which therefore may be reviewable under G. L. c. 211, § 3.”
Commonwealth
v. McCarthy,
For appeals from orders allowing new trial motions after July 1, 1979, see Mass. R. Crim. P. 30 (c) (8),
General Laws c. 278, § 29, was repealed by St. 1979, c. 344, § 46. Motions for new trial are now governed by Mass. R. Crim. P. 30 (b),
The motion judge ruled in the alternative: “I rule that ‘the original trial was infected with prejudicial constitutional error’.... I have no discretion to deny a new trial .... [I]f I had discretion I would grant the motion . . . .”
The confrontation clause was held applicable to the States through the Fourteenth Amendment in
Pointer
v.
Texas,
The Court stressed in Namet that it was not dealing with constitutional error, but only “a claim of evidentiary trial error.” In Douglas, supra at 420, the Supreme Court held that the denial of confrontation at Douglas’ trial was a violation of the second Namet test, however. Therefore, the motion judge did not err in ruling that a violation of the second Namet test could, in certain circumstances, rise to the level of constitutional error.
When the coparticipant witness invokes his privilege on the stand and is subsequently granted immunity out of the hearing of the jury, the prejudice is not so great because he is then subject to full cross-examination. See
