The district attorney seeks, by two petitions
*120
for writs of mandamus, originally heard by a single justice of this court, to require the trial judge and the justices of the Superior Court (the justices) to take all necessary steps to effect the return to the house of correction of one Roderick and one 'Sileno, each a defendant convicted in the Superior Court in the county of Middlesex for violation of the gaming laws. The single justice reserved each case without decision for the consideration of the full court upon the pleadings, a petition to intervene, and a stipulation of facts. The Attorney General (see G. L. c. 12, §§ 3, 10, 27;
Commonwealth
v.
Kozlowsky,
On May 9, 1960, Roderick was found guilty by verdict of a jury in the Superior Court of the crime of allowing premises to be used for registering bets and was sentenced to imprisonment for six months in the house of correction. He was taken upon mittimus to the Bast Cambridge jail and-remained there until May 19, 1960, when he was returned (pursuant to a writ of habeas corpus issued by order of the trial judge who presided at his trial) to the session of the Superior Court at which he had been sentenced. Roderick’s original sentence was thereupon revoked and a fine of $1,000 was imposed instead. The fine was paid. The district attorney objected to this action taken on May 19.
The proceedings in the Superior Court with respect to Sileno in relevant respects were the same as those with respect to Roderick, except that (a) Sileno was also convicted of the offence of permitting a lottery to be set up in a building, and each verdict finding him guilty was returned on May 5, 1960, (b) the revocation and modification of his sentence took place on May 18, 1960, and (c) his revised *121 sentence was for imprisonment for four months in the house of correction, which was suspended for three years for which period Sileno was placed on probation. There was then pending in the Superior Court a bill of exceptions presented by or in behalf of Sileno which, on May 18, 1960, Sileno waived in open court. No such bill of exceptions was pending on May 19 in behalf of Roderick, but it was stipulated that before, at, and after his trial Roderick had saved exceptions and that the time allowed for filing a bill of exceptions had not expired on May 19,1960.
On May 23, 1960, the district attorney with respect to each criminal defendant filed a petition for a writ of mandamus, alleging that the trial judge “did not have power or jurisdiction to vacate a sentence already imposed and executed,” and later amended to allege that “he appears in behalf of and as representative of the Commonwealth.” The justices of the Superior Court have filed an answer.
Roderick and Sileno each seasonably filed a petition to intervene which was denied without prejudice to its renewal at a later date. Counsel for each of them was given permission to participate fully in the proceedings before the single justice as amicus curiae, with leave to file briefs there. Each of them has filed a brief as amicus curiae before the full court. See
MacBrayne
v.
City Council of Lowell,
The principal question for decision is whether the trial judge, after Roderick and Sileno had started to serve their respective sentences but prior to the end of the May, 1960, sitting, had jurisdiction or power to revoke, as he did, the original sentences and to impose different sentences. Certain relevant principles appear to be well settled. If no action had been taken under the original sentences, such as delivering Roderick and Sileno to the house of correction to commence their terms, the trial judge could have revised the sentences during the same sitting of the court.

v.
Weymouth,
The district attorney relies upon statements in Massachusetts cases which indicate that revision of a sentence may not take place, even during the same term or sitting, if the sentence has been executed in part. The respondents, however, submit that these statements do not reflect any real judicial determination of the point now before us, and that in each instance the language, relied upon by the district attorney, was wholly unnecessary to the decision of the particular case then before the court.
The rule at common law seems to have been that, during the same term of court, a court of general criminal jurisdiction could alter a sentence. The circumstance that the sentence may have been partly served does not appear to have been treated in the decisions as in any way material. See Regina v. Fitzgerald, 1 Salk. 401; Inter Inhabitants of St. Andrew’s Holborn & St. Clement Danes, 2 Salk. 606, 607 (where “judgments . . . during the same term” are referred to as “in the breast of the judges” and where it was also said, per Holt, C.J., “The Court at the Old Bailey have altered and set aside their judgments ten times the same sessions .... The sessions as well as the term is but one day in law”); The King v. Price, 6 East, 323, 327-328. See *123 also Rex v. Fletcher, Russ. & Ry. 58, 60; The King v. Justices of Leicestershire, 1 M. & S. 442, 444.
The earliest Massachusetts case recognized the common law rule. See Commonwealth v. Weymouth, 2 Allen, 144, 145-146, dealing with an increase in a sentence from two years to three and a half years. The sentence was amended before the defendant (at p. 147) “was . . . taken or charged on the warrant . . . issued on the sentence as originally pronounced.” Chief Justice Bigelow, in discussing the power of the trial court to revise the sentence, said, “The true test by which to determine whether the power can be executed is, to ascertain whether it will affect the legal rights of the parties. If it will not, then it is a legitimate exercise of judicial discretion, of which no one has a right to complain.” The court then went on to consider whether the prisoner had been adversely affected by the change, and said that as the “sentence never went into operation” it was “in effect ... as if it had never been passed. So long as it remained unexecuted, it was, in contemplation of law, in the breast of the court, and subject to revision and alteration. He was not injured or put in jeopardy by it any further than he would have been by a conclusion or judgment of the court as to the extent of his punishment, which had not been announced. Until something was done to carry the sentence into execution, by subjecting the prisoner to the warrant in the hands of the officer, no right or privilege to which he was entitled was taken away or invaded, by revoking the sentence first pronounced, and substituting in its stead the one under which he now stands charged.”
Obviously the court in the
Weymouth
case was not directing its attention to a reduction in sentence during the same term of court with the consent of the prisoner. It had no occasion to do so. The case seems to rest upon the fact that, before execution of any part of the sentence, there was no more possibility of double jeopardy or of other unfairness to the prisoner than if the revised sentence had been imposed originally. Of course, where the sentence is
*124
revised in favor of the prisoner, he is not likely to complain of double jeopardy. Cf.
Bozza
v.
United States,
In
Commonwealth
v.
Foster,
Language like that quoted from the
Foster
case may be found in later cases. In
Commonwealth
v.
O’Brien,
In
Fine
v.
Commonwealth,
We conclude from this review of the Massachusetts cases that this court has never before had occasion to consider whether a trial judge, with the consent of a criminal defendant, may reduce a sentence of imprisonment during the same term or sitting of the court, even though the defendant may have been confined for a few days. Each statement relied upon by the district attorney either was unnecessary to the decision of the then pending case, or, directly or indirectly, was based upon, and seems to have misapplied, language used in the Weymouth case, where the sole problem was whether a sentence could be increased during the same term of court before the defendant had started to serve his sentence.
It may be suggested that to allow revision of a sentence during the court sitting involves some judicial interference with executive functions. Execution of a sentence is, of course, an executive function.

The reasoning in

v.
Benz,
Since the abolition of terms of court in the Federal Courts as periods of limitation, Rule 35 of the Federal Rules of Criminal Procedure (1946),
We think that sound practical considerations support the principle of the directly applicable decision of the Supreme Court of the United States in the
Benz
case. See
Gobles
v.
Hayes,
The present cases involve a substantial question directly concerning the powers of the Superior Court and the administration of criminal justice in that court. Because of this, we have felt it appropriate to consider the merits of that question rather than first to consider whether the dis *129 trict attorney may by mandamus seek review in this court of matters relating to the sentencing procedures of the Superior Court. Our decision on the principal question makes it unnecessary for us to consider this and various other procedural questions.
The trial judge had inherent power to take the action complained of within the limits of a sound discretion. No basis has been shown for requiring by mandamus any action in the Superior Court with respect to Roderick or Sileno. Each of the petitions is to be dismissed.
So ordered.
Notes
The Legislature has seen no such objection of policy in comparable situations. It has expressly authorized adjustments of sentences: (a) under G. L. c. 278, § 29 (as amended through St. 1957, c. 302), revision of sentence may be made within sixty days of any sentence “imposed without trial after a plea of guilty or nolo contendere”; (b) under G. L. c. 278, § 28A (as amended through St. 1945, c. 255, § 1); § 28B (as amended through St. 1945, c. 255, *128 § 2) ; § 28C (as amendedlihrough St. 1957, c. 777, § 36), in the ease of a sentence to State prison, revision of sentence may be had in the Appellate Division of the Superior Court; and (c) under G. L. c. 278, § 25 (as amended through St. 1955, c. 131, § 12), sentences may be revised in the District Court where a person originally convicted in a District Court waives an appeal to the Superior Court.
