In 1973, the defendant was convicted of murder in the first degree and armed robbery following a jury trial in Superior Court. In 1976, we affirmed his convictions, after reviewing the whole case on both the law and the evidence, pursuant to our duty under G. L. c. 278, § 33E (1984 ed.). For a summary of the evidence presented at trial, and the issues raised on appeal, see
Commonwealth
v.
Ambers,
In 1985, the defendant filed a motion for postconviction relief pursuant to Mass. R. Crim. P. 30 (a),
The defendant then petitioned a single justice of this court, pursuant to G. L. c. 278, § 33E, for leave to appeal the denial of his postconviction motion. On October 4, 1985, the single justice issued an order and reservation and report, bringing two of the defendant’s claims before the full court. First, the single justice reserved and reported the question whether the defendant’s claim that the judge used “trivializing language” in his jury instruction was a “new” claim within the meaning of G. L. c. 278, § 33E. The single justice made it clear that in his view the full court should reach the merits of the claim only if it concluded that it was “new.” The single justice also ruled that certain other challenges by the defendant to the jury instruction were not “new,” and therefore denied leave to appeal those issues, except as they might bear on the impact of the jury charge in its entirety. Second, the single justice allowed an appeal to the full court on the defendant’s challenge to his consecutive sentence for the armed robbery conviction. Finally, the defendant raised an additional claim that the application of statutory and common law principles relating to felony-murder illegally enhanced the crime of which he was convicted from murder in the second degree to murder in the first degree, which in turn resulted in an illegal enhancement of the sentence *707 imposed. The single justice ruled that this claim was not new, and therefore denied leave to appeal this issue.
1. First, we address the question reported by the single justice, whether the defendant’s claim that the trial judge used “trivializing” language in his jury instruction
1
is a “new” question for which an appeal should be allowed. Under G. L. c. 278, § 33E, no appeal shall lie from the denial of a postconviction 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.” The defendant argues that a “new” question for the purpose of this provision is one that previously had not been argued or addressed. The defendant did not object to the allegedly “trivializing” language of the instruction, either at the time of his trial, or on direct appeal. We did not address this issue in our plenary review of his conviction. See
Commonwealth
v.
Ambers,
An issue is not “new” within the meaning of G. L. c. 278, § 33E, where either it has already been addressed, or where it could have been addressed had the defendant properly raised it at trial or on direct review. “The statute requires that the defendant present all his claims of error at the earliest possible time, and failure to do so precludes relief on all grounds generally known and available at the time of trial or appeal.”
Commonwealth
v.
Pisa,
We first reversed a conviction on the ground that the trial judge’s instruction to the jury “trivialized” the Commonwealth’s burden of proof in
Commonwealth
v.
Ferreira,
2. The single justice allowed the defendant leave to appeal his claim regarding the duplicative nature of his sentence for armed robbery. The defendant was sentenced to thirty-five to forty years’ incarceration for his armed robbery conviction, to be served from and after his life sentence for murder. The defendant argues that this consecutive sentence should be vacated, because proof of the armed robbery did not require proof of any facts apart from those necessary to convict him of first degree (felony) murder.
Commonwealth
v.
Stewart,
3. The defendant attempts to argue before us that his sentence for murder in the first degree was an illegal enhancement of his conviction for armed robbery. The single justice expressly ruled that this claim was not “new,”

and therefore denied the defendant leave to appeal the issue to the full court.

A single
*711
justice’s denial of a petition for leave to appeal under G. L. c. 278, § 33E, is final and unreviewable.
Leaster
v.
Commonwealth,
4. The defendant also argues that he has been deprived of his right to the effective assistance of counsel, due to his trial counsel’s failure to object to the judge’s allegedly “trivializing” jury instruction. We do not address this claim, as the defendant did not obtain leave to appeal from the single justice as required by G. L. c. 278, § 33E. Leaster, supra.
5. The case is remanded to the single justice with instructions that he remand it to the Superior Court, where the sentence on the conviction for armed robbery is to be vacated and a new sentence is to be imposed, to run concurrently with the sentence imposed on the conviction of murder in the first degree. Because we have answered “No” to the question reported by the single justice, the appeal is otherwise dismissed.
So ordered.
Notes
In discussing the Commonwealth’s burden of proof, the judge equated proof beyond a reasonable doubt with the degree of certainty with which people make important decisions in their personal lives, such as the decision to undergo “open heart surgery” with a “fifty-fifty chance of survival.”
In
Pisa,
we analogized the “newness” requirement of G. L. c. 278, § 33E, to the standard under which a trial judge will consider claims raised in a motion for postconviction relief under Mass. R. Crim. P. 30,
We have never held, nor do we hold now, that a judge’s reference to important decisions in the personal lives of jurors necessarily constitutes error, constitutional or otherwise.
Commonwealth
v.
Smith,
The defendant argues that the constitutional significance of his argument was not apparent until our decision in
Commonwealth
v.
Garcia,
We make no distinction under G. L. c. 278, § 33E, between constitutional and nonconstitutional claims for the purpose of determining whether they are “new” within the meaning of that statute. The relevant inquiry is whether the legal basis for the defendant’s argument was sufficiently developed at the time of his trial or direct appeal so that he could reasonably be expected to have raised it at that time. This court’s disapproval of “trivializing” examples — even if it rested solely on common law principles — was first enunciated in 1972.
The single justice noted in his order that this issue also “seems insubstantial, but I need not so decide.”
The defendant cites
Gallinaro
v.
Commonwealth,
Gallinaro
did not involve a capital offense subject to the provisions of G. L. c. 278, § 33E. By its express terms, the statute prohibits an appeal from “any motion” filed in Superior Court after rescript, unless such appeal is allowed by a single justice. This includes postconviction motions challenging the legality of the defendant’s sentence. In
