Petitioner O’Shea was convicted of armed bank robbery, 18 U.S.C. § 2113(d), after a jury trial. Before sentencing, the district court reviewed a presentence report which disclosed that this was petitioner’s second such offense. It also showed eight state misdemeanor convictions ranging from assault and battery and unlicensed carrying of a revolver, to contributing to the delinquency of a minor. Stating,
inter alia,
that it regarded his record as “serious,” the court imposed a 20-year sentence, the permissible maximum being 25. Thereafter petitioner brought this 28 U.S.C. § 2255 proceeding asserting that all of the convictions except the prior bank robbery had been uncounselled, and that under United States v. Tucker, 1972,
Thereafter petitioner requested a rehearing. He accompanied this request with documents supporting his allegations that he had not been represented by counsel in the prior criminal proceedings, and furnished a substantial compilation of cases from other circuits holding, or suggesting, that the sentencing court must make its own determination of the constitutionality of prior convictions, that it relied on to enhance a sentence rather than require them to be formally set aside. This petition was referred back to the magistrate, who filed a memorandum stating, on the basis of a single example, that “quite often” the records of other courts did not give the full picture, and that in spite of the documentation submitted by petitioner the convictions may have in fact been proper. He concluded that since the “official court records are not sufficient in every case . . . the decision should be made elsewhere.” Again, no legal authority was cited in support of this conclusion, and no mention was made of the cases to the contrary elsewhere. The district judge, again without opportunity for petitioner to be heard, wrote at the foot of this memorandum, “Affirmed.”
If the only question before us was the legal correctness of the magistrate’s— and the district court’s—views, we would dispose of this case by a simple reversal on the authority of our later case of United States v. Sawaya, 1 Cir., 1973,
Under the Federal Magistrates Act, 82 Stat. 1108 (1968), 28 U.S.C. §§ 631-639, a magistrate’s primary function is not to supplant, but is to assist judges. Except to the extent that weight attaches to his findings when acting as a special master, we have made it clear that at least in matters of importance the magistrate decides nothing, but merely recommends, Reed v. Board of Election Comm’rs, 1 Cir., 1972,
“(1) service as a special master in an appropriate civil action
“(2) assistance to a district judge in the conduct of pretrial or discovery proceedings in civil or criminal actions ; and
“(3) preliminary review of applications for post-trial relief made by individuals convicted of criminal offenses, and submission of a report and recommendations to facilitate the decision of the district judge having jurisdiction over the case as to whether there should be a hearing.” 2
What would seem to us the plain meaning of the language of presently pertinent subsection (3) is borne out by the legislative history. The Committee on the Administration of the Criminal Law of the Judicial Conference of the United States, in a report on S. 945 recommended the addition of the final clause *777 of that section to “make it clear that it is the judge’s responsibility to make the ultimate decisions and to hold hearings on such applications, rather than that of the magistrate.” See Hearings before the Subcommittee on Improvements in Judicial Machinery of the Senate. Committee on the Judiciary on S. 3475, 89th Cong.2d Sess., and S. 945, 90th Cong., 1st Sess., at 245 (May 25, 1967).
However appropriate it may be for a judge to render an opinion that dismisses, sub silentio, all contrary authorities, a report by a magistrate in that vein scarcely “facilitate[s] the decision of the district judge” whose obligation it is to consider both sides of the case. To the extent that by its silence the report suggests that no other relevant material is known, it not only is not helpful, it is likely to be affirmatively misleading and detrimental. Whether the magistrate is dealing with a factual or a legal 3 situation, his basic obligation is to furnish a full account of all argumentatively relevant matters to enable the court to make the appraisal.
We do not mean by this that the magistrate, after setting forth all the factors, should not recite his own conclusions ; the statute expressly provides for his recommendation. The views of an experienced magistrate as to how the case should be decided can be of great assistance. 4 Indeed, because of the limited, and hence repetitive nature of his jurisdiction, a magistrate may come to have more familiarity with a question than does some individual judge. The report, however, is the primary obligation ; his recommendation, secondary.
This leads us to a comment upon the court’s duty, or more exactly, the weight to be given a report. The procedural error committed here of “affirming” the magistrate’s memorandum, as distinguished from entering a full order, suggests a possible misconception of substance. When acting under subsection (3) a magistrate’s conclusions are not to be given any weight, or presumption that they are to be adopted unless plainly wrong. The report, not to be thought of or denominated as an opinion, is not a decision of any sort. The original, and only order is the court’s, which is entirely free to do as it chooses. See n.4, ante.
Correspondingly, unless the particular claim is frivolous, or the matter requires immediate disposition, it would normally seem desirable to allow parties to comment before a magistrate’s recommendation is acted on.
Cf.
Rainha v. Cassidy, ante,
The fact that subsection (1) makes a general provision for the appointing of a magistrate as a special master, and subsection (3) gives a much more specific recitation for post convic *778 tion relief proceedings in itself suggests that the latter is the sole procedure to be adopted in such instance. If there could be doubt about this, we believe it to be answered by the Report of the Committee on the Administration of the Criminal Law of the Judicial Conference, quoted ante. When a criminal proceeding has reached the stage of final sentence having been imposed, any further decision should be by the district judge, and not by a magistrate even to the limited extent of making findings of fact with the weight that normally attaches to the findings of a master. This should particularly be so, as a matter of comity, in the field of federal state relations when dealing with habeas corpus.
The Sixth Circuit has concluded that in the case of post conviction relief a magistrate should not hold evidentiary hearings at all. Wedding v. Wingo, 6 Cir., 1973,
Returning to the merits of this case, the government takes the position that the record “conclusively shows,” 28 U.S.C. § 2255, that petitioner is entitled to no relief because the misdemeanor convictions were inconsequential. It may be, on judicial reflection, that in the sum total of things they were of no material consequence, but we could not conceivably say so as matter of law in the light of the sentencing judge’s specific reference to the seriousness of petitioner’s record.

We note that our uncertainty in United States v. Sawaya, ante, whether Argersinger v. Hamlin, 1972,
A question remains, whether the remand should be to the original sentencing judge or to another. As we recognized in Halliday v. United States, 1 Cir., 1967,
*779
The most important matter is the nature of the new proceeding and its relationship to the old one. If, for example, the case is remanded for a new factual determination by the district judge, the fact that he has already made a resolution, particularly if this involved error on his part, may make it difficult for him to reapproach the question with a free and open mind. On the one hand, he may find it difficult to rid himself of his prior conclusions. More likely, he will tend to lean over backwards. Even if he overcomes both difficulties, it may not be without great personal effort. At the same time, both parties may be apprehensive of the obstacles in the way of its accomplishment. In these cáses we have indicated a strong preference for a new fact finder. Murray v. United States, 1 Cir., 1962,
On the other side of the ledger, reconsideration by the original judge may be affirmatively desirable when familiarity with the case is important, and for a new judge to achieve familiarity would require wasteful delay or duplicated effort, or when the original judge has unique knowledge of relevant facts which he might legitimately use to augment the record.
See, e. g.,
United States v. Cleveland, 7 Cir., 1973,
Such circumstances, to the extent that they are present, call for a balancing.

Thus, in a resentencing on a plea, even though the original judge committed no error, but a new judge could readily learn all there was to know at the hearing and through reading the presentence report, we have remanded to a new judge. Mawson v. United States, 1 Cir., 1972,
As against this, there would seem to be no persuasive factor contraindicating a return to the original judge. No criticism of him was involved in the post-sentencing discovery that he may have been given an impermissible presentence report, and there would seem no reason to assume that he would be unable to change his mind as to the appropriate sentence, if the changes so warranted. Rather than conceivable annoyance, the original judge would have every reason to welcome the opportunity to correct any inadvertent aggravation of injustices that may have been done the defendant in another court.
See
United States v. Tucker, ante,
In conclusion, we do not suggest that in this case, or in any case other than where the original judge was reversed for committing error in the course of making a finding of fact, a judge should not be free to decline to accept a remand, or, contrarily, to call for a remand to himself if, in his discretion, he believes it appropriate. Unless otherwise stated, our views in this area are hortatory, not imperatives. Happily we have no reason in this circuit to fear actual vindictiveness in the exercise of such discretion. The importance of the other considerations may vary from case to case, and although we may set general preferences, the final balance can often be best determined, in light of the general principles that we have outlined, by the district judge himself.

see
United States v. Martinez, 7 Cir., 1969,
. These provisions were adopted by the Rules for United States Magistrates of the Massachusetts District, Rule 2(b).
. How far a magistrate should make a legal study is a matter to be determined in the particular instance. In the case at bar a legal study in some depth had been submitted to him which, although he might have thought wrong, he could not have thought irrelevant.
. “A qualified, experienced magistrate will, it is hoped, acquire an expertise in examining these [post conviction review] applications and summarizing their important contents for the district judge, thereby facilitating his decisions. Law clerks are presently charged with this responsibility by many judges, but judges have noted that the normal 1-year clerkship does not afford law clerks the time or experience necessary to attain real efficiency in handling such applications.” Senate Committee on the Judiciary, 90th Cong., 1st Sess., “The Federal Magistrates Act”, report on S.945, Rep.No.371, at 26 (June 28, 1967).
. Petitioner argues that since the court used the word “record” in the plural, it must have had in mind his misdemeanor convictions as well as the single, admittedly valid, armed robbery conviction. This is an unwarranted assumption. The court was addressing two defendants simultaneously, and would naturally have used the word in the plural even if each defendant had had only one relevant prior conviction. It may be that the court gave substantial weight to the misdemeanor convictions, or it may be that it did not. We express no opinion, except to say that the use of the word record in the plural supplies no answer.
. Another factor that enters into the scale is the relative unavailability of a new judge in a single-judge district.
