This proceeding on a writ of error was reserved and reported by the single justice on the petition, the answer, the return of the Chief Justice of the Superior Court, the transcript of the trial in the Superior Court, the findings of the single justice and one assignment of error. The assignment of error is that the judge in the Superior Court “erred in receiving in evidence the fact that. . . [Arsenault] had pleaded guilty to the charge on trial in the Newton District Court while unrepresented by counsel.”
The case as it originally came to us on appeal under G. L. c. 278, §§ 33A-33G, is reported sub nomine
Commonwealth
v.
*576
Devlin,
We summarize the facts found by the single justice relating to the assigned error, augmented or amplified where appropriate by undisputed facts of record. On the evening of February 4, 1955, Arsenault was arrested in connection with the shooting to death, during an attempted robbery, of a young man in Newton. The arrest took place a few minutes after the crime. The following morning a probable cause hearing was held in the Newton District Court. During the hearing, at which Arsenault was not represented or assisted by counsel, he “pleaded guilty” to two complaints charging, respectively, murder and assault with intent to rob. He was bound over for the grand jury who returned an indictment charging Arsenault with murder. On February 11, 1955, he was arraigned in the Superior Court and pleaded not guilty to the indictment. When arraigned, he was not represented by counsel. On February 21, 1955, on Arsenault’s motion, counsel nominated by him was assigned to defend him under G. L. c. 277, §§47 and 55, and Rule 95 of the Superior Court (1954). Thereafter, at all material times, Arsenault was represented by and had the assistance of counsel. He was allowed funds for the employment of an investigator and psychiatrists. Upon the appointment of counsel he was granted thirty days within which to file special pleas. The Commonwealth filed particulars in response to his motion. On June 28, 1955, at the close of the evidence at the trial, his counsel filed and was given a hearing on a motion to quash the indictment, which was denied on the merits.
At the trial Arsenault testified in his own defence. Under direct examination he testified that he, with a codefendant, each with a gun in hand and a silk stocking as a face mask, and Arsenault having in addition a rope in a pocket inside his topcoat, entered a dwelling for the purpose of taking one Silverman’s money, and that the gun which fired the fatal bullet was in his hand when the victim was shot. On
*577
cross-examination the district attorney read to Arsenault the complaint from the files of the Newton District Court charging him with murder and asked him how he had pleaded to it. Arsenault replied that he did not remember. He was asked to read the complaint, including the plea, and having done so said that his memory was not refreshed. The district attorney then incorporated part of the complaint and the plea in a question to Arsenault and asked him if it refreshed his memory and he replied that it did not, that he did not know what he had said. Eventually, in the Commonwealth’s rebuttal, a witness who had been present at the probable cause hearing testified that he heard Arsenault plead guilty to both complaints.

The jury found him guilty of murder in the first degree. He appealed to this court on assignment of errors, among which was the admission of his pleas made in the District Court. This court held the pleas admissible and affirmed the judgment.
Commonwealth
v.
Devlin,
Arsenault’s present petition is founded on the holding of the Supreme Court of the United States in
White
v.
Maryland,
At the outset it should be noted that Arsenault does not argue, and quite rightly, we think, that
Hamilton
v.
Alabama,
where under Alabama law the absence of counsel at the arraignment stage was deemed to be critical, has any application to the present case. Although Arsenault was without counsel when he pleaded not guilty at his arraignment in the Superior Court, the order of the judge relative to the filing of special pleas, entered as soon as counsel was appointed, affirmatively shows that all of the defences which could have been available to him were in fact made available to him. Some were used by him. We therefore do not have a case where "the degree of prejudice can never be known.”
Hamilton
v.
Alabama,
We accordingly focus our attention on the applicability of
White
v.
Maryland,
In reaching our conclusion we must be guided by our understanding of the rationale underlying the decisions of the Supreme Court regarding the retroactivity of constitutional rules of criminal procedure established by that court for State courts. These decisions are:
Linkletter
v.
Walker, Warden,
It appears therefore that the cases where retroactivity has been discussed are cases where retroactivity has been denied. In
Stovall
v.
Denno, Warden,
however, the court re
*580
ferred to those cases where retroactive effect was expressly or implicitly granted, saying "It is true that the right to the assistance of counsel has been applied retroactively at stages of the prosecution where denial of the right must almost invariably deny a fair trial, for example, at the trial itself,
Gideon
v.
Wainwright,
Apart from the foregoing statements which are explanatory of the criteria followed in cases where retroactive effect had already been given, the four cited decisions point to affirmative and negative propositions which bear upon the issue of retroactivity. Retroactivity in each case must be determined “by looking to the peculiar traits of the specific [new] ‘rule in question.’”
Similar negative propositions may be inferred from other decisions. The fact that a condemned practice occurred at a "critical stage” of the proceedings does not require that the rule be applied retroactively. In
Tehan, Sheriff,
v.
United States ex rel. Shott,
retroactivity of
Griffin
v.
California
was denied on the dual grounds of the justified long established reliance on
Twining
v.
New Jersey,
Cognate to this point also is the holding in
Stovall
v.
Denno, Warden,
Finally, none of the cases dealing with retroactivity has considered the gravity of the offence or the severity of the sentence to be a factor in the resolution of the issue. We have no reason to believe that they should be factors in the consideration of a case such as the one before us.
On the affirmative side, the Supreme Court of the United States, with respect to retroactivity, has applied, though in varying forms of expression, a pragmatic test: the court looks to (1) the purpose of the new rule, (2) the reliance placed upon the old rule, and (3) the effect on the administration of justice of a retroactive application of the new rule.
Linkletter
v.
Walker, Warden,
*582
With these guidelines we enter upon the inquiry whether in our judgment the rule of
White
v.
Maryland
should be retroactive. The problem is before us only because the judge who presided at the trial of the case on the merits admitted testimony of Arsenault’s plea of guilty at the probable cause hearing in the District Court, where he was without counsel. At this point it may be useful to pause and make a few relevant observations. The offences complained of were not within the jurisdiction of the District Court. G. L. c. 218, § 26. Under the practice in this Commonwealth and many other States, a District Court or corresponding judicial officer can make no determination of guilt or innocence of charges such as those made against Arsenault. No rights need be asserted and no defences need be reserved at a probable cause hearing.
Commonwealth
v. O’Leary,
We do not question that the testimony at the trial of Arsenault’s plea of guilty in the District Court had an adverse effect. Under White v. Maryland, the ruling in the Superior Court admitting testimony of the pleas converted the probable cause hearing, an otherwise innocuous stage in the judicial process, into a “critical stage,” at which Arsenault was without counsel. It would appear, therefore, that the sole purpose of the rule implicitly established in White v. Maryland is to see to it that a defendant at his trial is not adversely affected by an admission of guilt made by him at a probable cause hearing when he was without counsel.
Our next consideration is the reliance placed upon the old rule. The rule that a plea of guilty constituted an admission
*583
which could be used against the defendant appears to have been first challenged in this Commonwealth in 1874 in
Commonwealth
v.
Ayers,
The retroactive application of the
White
rule would have a serious impact upon the administration of criminal justice in this Commonwealth and elsewhere. “Empirical statistics are not available to us,” as they were not available to the Supreme Court in the
Tehan
case,
In contemplation of the judgment which must be made on the “question of probabilities,”
Stovall
v.
Denno, Warden,
All things considered, it is our conclusion that White v. Maryland is not retroactive. Accordingly the judgment is affirmed. 3
So ordered.
Notes
The complaints, in specie, were not admitted in evidence, as might be inferred from the findings of the single justice.
In the Nadeau case, the defendant’s plea of guilty at the probable cause hearing was admitted without objection at the trial.
Our affirmation, of the judgment also reaffirms the admonition of Chief Justice Wilkins in
Commonwealth
v.
O’Leary,
