By direction of the Supreme Court, Cuyler v. Sullivan, --- U.S. ----, 100 S. Ct. 1708, 64 L. Ed. 2d 333 (1980), John Sullivan's petition for habeas corpus relief from his conviction on two counts of first degree murder is once again before this court. The evidence supporting this conviction and the detailed procedural history of this case are fully set forth in this court's opinion, 593 F.2d 512 (3d Cir. 1979). We shall satisfy ourselves with a brief review of the case.

Sullivan was convicted of murdering John Gorey, a minor labor union official, and his girlfriend, Rita Janda. His conviction was affirmed by an equally divided Pennsylvania Supreme Court. Commonwealth v. Sullivan, 446 Pa. 419, 286 A.2d 898 (1971). Petitioner then filed the instant petition, alleging seven grounds for relief. U. S. ex rel. Sullivan v. Cuyler, 593 F.2d 512, 515-16 (3d Cir. 1979).1 Two of these grounds concern us here. First, petitioner alleged that the factual basis underlying his conviction was so totally devoid of evidentiary support as to deny him due process. Second, petitioner alleged that he was denied effective assistance of counsel because his attorneys also represented his two other defendants whose interests conflicted with his. Sullivan based his ineffective assistance of counsel claim on the decision that Sullivan rest his defense without putting on any evidence.

The district court applied the standard of Thompson v. Louisville, 362 U.S. 199, 80 S. Ct. 624, 4 L. Ed. 2d 654 (1960) and held that there was sufficient evidence to support the conviction. On the issue of conflict of interest, the district court concluded that there could be no conflict because there was no "dual representation." To support this finding, the district court relied on the fact that two attorneys were involved in the defense, G. Fred DiBona2 and A. Charles Peruto. Although each entered appearances on behalf of all three defendants, there was evidence that Judge DiBona was chief counsel for Sullivan, while Peruto had primary responsibility for the cases of the other two defendants. The court further found that even if there was "multiple representation," there was no conflict of interest in the case, either actual or potential. The district court denied the petition for habeas corpus.

On appeal, this court reached only the conflict of interest issue. We held, as a matter of law that there was sufficient involvement by both attorneys in all of the cases to constitute multiple representation. Moreover we found that there was at least a possibility of a conflict of interest, which, we held, was sufficient to constitute a violation of petitioner's sixth amendment right to effective assistance of counsel. Accordingly, we directed that the district court grant the petition for habeas corpus.

The Supreme Court granted certiorari, 444 U.S. 823, 100 S. Ct. 44, 62 L. Ed. 2d 30 (1979) and vacated our order. The Court agreed that there was, in fact, dual representation, but held that a showing of a potential conflict of interest was insufficient to taint a criminal conviction. Cuyler v. Sullivan, --- U.S. ----, ----, 100 S. Ct. 1708, 1717, 64 L. Ed. 2d 333 (May 13, 1980). Instead, the Court held that a defendant "must establish that an actual conflict of interest adversely affected his lawyer's performance." Id. The Supreme Court remanded to this court to apply the proper legal standard.

Although we are loath to volley this case within the federal courts, we think it appropriate that the case be remanded to the district court, so that it may be considered in light of the Supreme Court's decisions in both Cuyler v. Sullivan (as to actual conflict) and Jackson v. Virginia, 443 U.S. 307, 99 S. Ct. 2781, 61 L. Ed. 2d 560 (1979) (as to sufficiency of evidence).

We turn first to the question of the sufficiency of the evidence. Subsequent to the district court's review of the evidence supporting Sullivan's conviction, the Supreme Court formulated a new standard for reviewing sufficiency of evidence in Jackson v. Virginia, 443 U.S. 307, 99 S. Ct. 2781, 61 L. Ed. 2d 560 (1979). The new standard requires evidence necessary to convince a trier of fact beyond a reasonable doubt of the existence of every element of the offense. The previous standard of Thompson v. Louisville, 362 U.S. 199, 80 S. Ct. 624, 4 L. Ed. 2d 654 (1960), which was applied here by the district court, was radically different from Jackson in that it permitted a conviction to be sustained unless there was no supporting evidence in the record. In light of the intervening Supreme Court decision, we exercise our discretion, Singleton v. Wulff, 428 U.S. 106, 121, 96 S. Ct. 2868, 2877, 49 L. Ed. 2d 826 (1976), to permit the district court to have the first opportunity to apply the Jackson formulation of sufficiency to the evidence on which Sullivan was adjudged guilty. We think this review is especially important in light of the Pennsylvania Supreme Court's even division when it reviewed the evidence supporting Sullivan's conviction. If the district court concludes that the evidence is insufficient under Jackson, the writ should issue and the court need not further address the remaining grounds in the petition.

Turning to the second issue, although the district court did not find the presence of actual conflict of interest rendering counsels' assistance ineffective, we note that it did so only after first finding that no "dual representation" existed. This court, however, has found that dual representation did exist. Sullivan v. Cuyler, 593 F.2d 512 (3d Cir. 1979), aff'd on this ground, reversed on other grounds, 444 U.S. 823, 100 S. Ct. 1708, 64 L. Ed. 2d 333 (1980). Therefore, we think it appropriate that the district court reexamine its finding of no actual conflict with the certainty of knowledge of the existence of "dual representation" and with the benefit of the Supreme Court's pronouncements in Cuyler v. Sullivan, 444 U.S. 823, 100 S. Ct. 1708, 64 L. Ed. 2d 333 (1980).

As to the remaining claims in the petition for habeas corpus, we have not decided and will not pass upon them until the district court reconsiders the sufficiency of evidence and ineffective assistance of counsel claims. This best serves the policy disfavoring fragmented consideration of habeas corpus claims. See, e.g., Gonzales v. Stone, 546 F.2d 807 (9th Cir. 1976). Moreover unified consideration of the claims in the petition well satisfies the interests of justice because the cumulative effect of the alleged errors may violate due process, requiring the grant of the writ, whereas any one alleged error considered alone may be deemed harmless.3

The district court may, however, decide to reconsider any of these remaining issues on such terms and under such conditions as are appropriate.

The case will be remanded to the district court for proceedings consistent with the foregoing.
