In 1964 the petitioner in this matter pleaded guilty to an indictment for indecent assault and battery on a child under the age of fourteen (G. L. c. 265, § 13B) and was sentenced to serve a term of from four to five years at the Massachusetts Correctional Institution at Walpole. In 1969, following the conclusion of proceedings brought under G. L. c. 123A, § 6, a judge of the Superior Court determined the petitioner to be a sexually dangerous person (SDP) and ordered him committed to the treatment center (G. L. c. 123A, § 2) at the Massachusetts Correctional Institution at Bridgewater for the indeterminate statutory period of from one day to life. See, generally, the cases cited in Commonwealth v. Lamb, 1 Mass. App. Ct. 530, 531 (1973), S. C. 365 Mass. 265 (1974), 372 Mass. 17 (1977). In 1973 a second judge of the Superior Court, in proceedings brought under G. L. c. 123A, § 9, determined that the petitioner continued to be an SDP and denied his petition that he be released from the center. No appeal was taken from either of those determinations, despite the fact that the petitioner appears to have been represented by counsel at all times now material. Several months after the second determination the petitioner filed the present petition for a writ of habeas corpus by which he again seeks to be released from the center.1 The petition was, after hearing, ordered dismissed by a third judge of the Superior Court (trial judge). The petitioner has appealed, urging three separate grounds for reversal.
1. The petitioner contends first that he was denied his constitutional rights to confront and cross examine the witnesses against him (art. 12 of the Massachusetts Declaration of Rights and the Sixth [by reason of the Fourteenth] Amendment to the Constitution of the United States) by the admission in evidence during the original proceedings under § 6 of the testimony of two psychiatrists called by the Commonwealth concerning the contents of certain records which had been made available to them *284at the center and which referred to (a) the petitioner’s adolescent homosexual activities with feeble-minded boys and (b) his assault on two young boys while he was on parole from a Maine prison where he had been serving a portion of his 1964 Massachusetts sentence.2 3**The evidence in question was all hearsay of a type which did not fall within any of the limited exceptions to the hearsay rule which were created by G. L. c. 123A, § 5, as subsequently construed in Commonwealth v. Bladsa, 362 Mass. 539, 540-542 (1972). If the present case were now before us on direct appeal from an original order of commitment under § 6 and it appeared that the order had been influenced by evidence of the nature and source already described, we would reverse the order on the authority of the Bladsa case. Compare Commonwealth v. Lamb, 1 Mass. App. Ct. at 532-533. But the present case is not here on such an appeal; it is here on appeal from an order denying a petition for a writ of habeas corpus. It is now clear, as it was at the time of the entry of the order here appealed from, that the petitioner’s remedy for a Blasda-type violation was to file a petition for his release under G. L. c. 123A, § 9, which would put the Commonwealth to the burden of proving beyond a reasonable doubt, without resort to evidence of the type complained of, that the petitioner continued to be an SDP. Andrews, petitioner, 368 Mass. 468, 477, 485-486, 489 (1975) .3
It appears from the record in this case that the petitioner has already availed himself of that remedy, but without success. The record includes the transcript of the 1973 hearing under § 9 which has already been referred to *285and at which another judge of the Superior Court determined that the petitioner continued to be an SDP without regard to any of the evidence now complained of which had been admitted at the 1969 hearing under § 6. During the course of the 1973 hearing two psychiatrists called by the Commonwealth testified without objection (see Peterson, petitioner, 354 Mass. 110,115-116 [1968]) to the contents of the same records concerning the petitioner’s adolescent homosexual activities and the assault committed by him while on parole in Maine; each psychiatrist expressed the ultimate opinion that the petitioner continued to be an SDP. At the conclusion of the testimony of each witness the judge specifically inquired of each whether he would continue to entertain the same ultimate opinion if he had been unaware of the evidence now complained of; each witness answered in the affirmative.4 The judge made it clear that he excluded that evidence from his consideration, both in denying the petitioner’s motion for a “directed finding” and in his own finding and ruling that “the petitioner... is now, beyond reasonable doubt of this [c]ourt, a sexually dangerous person, within the meaning of [G. L. c. 123A, § 9].” See and compare Commonwealth v. McHoul, 372 Mass. 11, 13 (1977).
Accordingly, we conclude that the petitioner has failed to prove that his continued confinement at the center is the result of evidence improperly admitted during the course of the original 1969 hearing under § 6.
2. The petitioner’s second contention is that his continued confinement at the center violates due process of law and constitutes cruel and unusual punishment because the treatment provided there neither benefits him nor provides any reasonable likelihood of his ultimate release. See Commonwealth v. Page, 339 Mass. 313, 317-318 (1959); Commonwealth v. Hogan, 341 Mass. 372, 376-377 (1960); *286Nason v. Superintendent of Bridgewater State Hosp. 353 Mass. 604, 611-614 (1968). On analysis, the argument consists of a summary of the evidence most favorable to the petitioner on the question whether he can ever be cured of the traits which have resulted in the two judicial determinations that he is an SDP. The peroration of the argument is that “[a] determination that [petitioner is untreatable is warranted.” We think the argument (1) proceeds on the erroneous premise that the Commonwealth is constitutionally obligated to provide the petitioner with treatment which will result in curing his traits (see Commonwealth v. Major, 354 Mass. 666, 668 [1968], cert. den. 393 U. S. 1109 [1969]; Newton, petitioner, 357 Mass. 346, 352 [1970]) and (2) ignores the import of much of the evidence offered at the hearing on the present petition.
At that hearing there was both oral and documentary evidence to the effect that the petitioner has consistently failed to respond to the conventional form of individualized psychotherapy which has been offered to him on a weekly basis ever since his original commitment to the center in 1969. A staff psychologist assigned to the petitioner testified that the staff had determined that the petitioner would benefit from attendance at and participation in the biweekly sessions of a particular group of individuals who, like the petitioner, are of limited mental capacity and do not respond to the conventional or orthodox modes of psychotherapy, at which the emphasis would be and has been on encouraging behavioral changes which facilitate the day to day management of life and the conduct of personal relationships. The petitioner, despite the continued urging of staff members, has consistently refused to attend the group meetings on the grounds (as stated by him) that his attendance would result in personal inconvenience and would be of no value or benefit to him.5 There was evidence *287that the petitioner is amenable to a change in his life and that his being permitted to work as a trusty on the farm at Bridgewater has “manifestly changed his behavior in a positive fashion.” The same psychologist specifically testified that “[a] number of variables, outside of therapy, could favorably affect... [the petitioner], and his nonattendance [at the group sessions] would not preclude his reaching a point where he could be released.”
On the foregoing and other evidence the judge made the following findings and rulings: “I find as fact that the petitioner was being treated in the past and continued to be treated up until the time of this hearing consistent with the best modes of treatment available to the [c] enter. The petitioner was offered and encouraged and reasonable efforts were made to admit him to group therapy which he refused. I further find as fact that this mode of treatment was considered in the patient’s best interest and his refusal to participate in the group therapy substantially limited the capacity of the [c] enter staff to provide him with more hopeful therapy----The responsibility of the [c] enter is to provide reasonably adequate treatment, to maintain the patient so as to secure the community from the danger of such a person in its presence, and to give sufficient opportunity within the terms of... [the] statute and the constitution to the petitioner to enable him to progress and recover and secure his timely release----I further find that treatment has been given to petitioner and that there have been signs of progress albeit a very slow progress and one not necessarily indicative of future recovery but nonetheless such treatment has been reasonably provided. In any event, there was evidence which I find credible that the [c] enter’s therapists have made and continue to make substantial efforts to induce the petitioner to subscribe to a form of treatment that would provide the most potential for his recovery.”
All the foregoing findings were warranted by the evidence introduced at the hearing of the present petition. Indeed, there is no serious argument to the contrary. We think it clear that the petitioner has been “offered treat*288ment which is suitable for him to the best of the staff's collective judgment, [that the] evidence does not support the conclusion that, as to... [the petitioner], the center’s treatment is in fact inadequate... [and that there has been] no showing... that... [the petitioner’s] release or a different commitment is... required.” Newton, petitioner, 357 Mass. at 352-353. In reaching these conclusions we join the trial judge in rejecting the contention that the treatment which is offered must necessarily be declared inadequate whenever the staff is unable to convince the patient of the wisdom of accepting what is offered.
3. The petitioner’s final contention is that he was deprived of due process and equal protection of law because the original order of indeterminate commitment under G. L. c. 123A, § 6, was not entered until twenty-six days following the expiration of the sentence which had been imposed on him in 1964. The judicial proceedings which ultimately led to that commitment were commenced approximately a year prior to the expiration of the petitioner’s sentence, but there is nothing in the record to suggest any deliberate or unreasonable delay on the part of the Commonwealth in bringing those proceedings to fruition. The petitioner concedes, in essence, that all his arguments on this point were considered and rejected in Lamb, petitioner, 368 Mass. 491, 496-501 (1975). His request for reconsideration of the decision in that case is denied. Compare Burke v. Toothaker, 1 Mass. App. Ct. 234, 239 (1973); Erhard v. F. W. Woolworth Co., post, 770 (1977), further appellate review granted, 372 Mass. 871 (1977), and cases cited.
Judgment is to be entered dismissing the petition for a writ of habeas corpus.
So ordered.
The petition was originally filed in the Supreme Judicial Court but was transferred to the Superior Court for disposition.
The transcript of the § 6 proceedings, which was introduced as an exhibit in the present case, fails to disclose (or even suggest) that any of the petitioner’s objections or exceptions to the evidence in question was directed to the constitutional point now sought to be argued. In this respect the present case bears a close resemblance to the many appeals in criminal cases in which every admission of hearsay suddenly assumes grave constitutional dimensions.
The Andrews case was decided on August 13, 1975, more than two months prior to the entry of the order appealed from in the present case.
As to the admissibility of a psychiatric opinion based in part on inadmissible hearsay which has been made available to the witness at the treatment center, see Andrews, petitioner, 368 Mass. at 475, and Commonwealth v. Lamb, 372 Mass. at 22.
See and compare Newton, petitioner, where the court said (357 Mass. at 352): “Newton has refused treatment (posing no threat to his physical well-being) designed to help him, and thus he is not now in a position to complain about its inadequacy.”
