This is an appeal from the dismissal of a petition for a writ of habeas corpus. Defendant was convicted of various crimes, including first degree murder, in connection with a bank robbery in Worcester, Massachusetts in 1965. The facts are detailed in the opinion of the Supreme Judicial Court affirming the convictions, Commonwealth v. Subilosky, 352 Mass. 153, 155-157, 224 N.E.2d 197 (1967) and need not be repeated.

The chief issue presented here concerns the use of prior convictions to impeach the defendant's credibility. Counsel on direct-examination elicited the fact that the defendant had spent a substantial amount of time in prison but did not go into details. On cross-examination, evidence of six prior convictions1 was introduced over objection that (a) such evidence was prejudicial in view of the fact that the defendant had admitted spending a great deal of his life in prison and (b) at the time of these convictions he was not represented by counsel. On appeal to the Supreme Judicial Court the defendant limited his objection regarding the prior convictions to their being cumulative and did not press the lack of counsel point.

Defendant's present contentions are based largely on the decision of Burgett v. Texas, 389 U.S. 109, 88 S. Ct. 258, 19 L. Ed. 2d 319 (1967), decided after defendant's time for seeking certiorari in this case had expired. There the Court reversed a conviction under a recidivist statute on the grounds that there had been a denial of the right to counsel at one of the prior convictions. The Court held: 'To permit a conviction obtained in violation of Gideon v. Wainwright to be used against a person either to support guilt or enhance punishment for another offense * * * is to erode the principle of that case.' Burgett, supra at 115, 88 S. Ct. at 262. Defendant argues that Burgett cannot be distinguished by the fact that in this case the prior convictions were admitted merely for purposes of impeachment.

We find it unnecessary to reach the substance of this contention, however, because there is a threshold question concerning exhaustion of state remedies. See 28 U.S.C. 2254. Defendant is quite correct that he cannot be expected to have anticipated the Burgett decision but it in no wise follows that he is free now to come to the federal rather than state courts to obtain what relief, if any, he may be entitled to pursuant to Burgett. Roberts v. Russell, 392 U.S. 293, 88 S. Ct. 1921, 20 L. Ed. 2d 1100 (1968) and Tehan v. United States ex rel. Shott, 382 U.S. 406, 86 S. Ct. 459, 15 L. Ed. 2d 453 (1966) do not suggest otherwise. In Roberts the only question was whether Bruton v. United States, 391 U.S. 123, 88 S. Ct. 1620, 20 L. Ed. 2d 476 (1968) was to be applied retroactively. The applicability of Bruton to the facts was not in question. Similarly, in Tehan the only question was whether Griffin v. California, 380 U.S. 609, 85 S. Ct. 1229, 14 L. Ed. 2d 106 (1965) was to be given retrospective application.2 Additionally, the Supreme Court of Ohio had already decided that very question in the negative. Tehan, supra, 382 U.S. at 409 n. 3, 86 S. Ct. 459. Failure to require reconsideration by state courts in cases such as this does not justify the inference that as a rule such resort is not necessary. See Needel v. Scafati, 412 F.2d 761 (1st Cir. 1969). To the contrary, it has often been held that one must give the state courts an opportunity for reconsideration in the light of new principles announced by the Supreme Court. Boyer v. City of Orlando, 402 F.2d 966 (5th Cir. 1968); Powers v. Hauck, 399 F.2d 322 (5th Cir. 1968); Brown v. New Jersey, 395 F.2d 917 (3d Cir. 1968); Baines v. Swenson, 384 F.2d 621 (8th Cir. 1967); see In Re Whittington, 391 U.S. 341, 88 S. Ct. 1507, 20 L. Ed. 2d 625 (1968).

This is not a case where effective state remedies are now foreclosed, see Fay v. Noia, 372 U.S. 391, 434-435, 83 S. Ct. 822, 9 L. Ed. 2d 837 (1963). Nor are we in effect requiring repetitious applications to the state courts concerning the same issues. For, quite apart from any question of defendant's failure to press his present contentions before the Supreme Judicial Court on direct appeal, these claims took on an entirely different character after the Burgett decision. A petitioner must return to the state courts with new constitutional claims,3 see Needel, supra, at 765. This is in effect a new claim.

There is no injustice in requiring the defendant to pursue his state remedies. This was, after all, a state conviction and comity requires that federal intervention in such matters be as restricted as possible. Just as the defendant has a right to advance new claims on the basis of developing constitutional principles, the state courts have a right to hear them, at least in the first instance.

We consider briefly one other matter. After the veniremen from whom the petit jury was selected had been sequestered for four days it was discovered that one of their number was a relative of the murder victim. This man was excused immediately but the defendant complains because the entire panel was not discharged. Of course, it was well that the one potential juror was excused. But in view of the fact that the trial court interrogated the jurors as to whether they had any bias or prejudice and whether they had formed any opinion as to the guilt or innocence of the defendant, we do not think that the defendant was denied his right to an impartial jury by the failure to dismiss the entire panel.

Affirmed.
