Task: songer_casetyp1_1-2

What follows is an opinion from a United States Court of Appeals.
Your task is to identify the issue in the case, that is, the social and/or political context of the litigation in which more purely legal issues are argued. Put somewhat differently, this field identifies the nature of the conflict between the litigants. The focus here is on the subject matter of the controversy rather than its legal basis.
Your task is to determine the specific issue in the case within the broad category of "criminal". 

OPINION OF THE COURT
PER CURIAM:
In this habeas corpus case brought by a state prisoner, a certificate of probable cause was issued by the district court to afford this court an opportunity to consider the district court’s ruling that Coleman v. Alabama, 399 U.S. 1, 90 S.Ct. 1999, 26 L.Ed.2d 387 (1970), was not retroactive. It is not retroactive. Adams v. Illinois, 405 U.S. 278, 92 S.Ct. 916, 30 L.Ed.2d 202 (1972); United States ex rel. Walker v. Maroney, 444 F.2d 47 (3d Cir. 1971).
We have also considered the district court’s treatment of the competency of counsel issue. We find that the court correctly judged the attorney’s performance in accordance with the normal competency standard of Moore v. United States, 432 F.2d 730, 737 (3d Cir. 1970).
The judgment of the district court will be affirmed.
