OPINION OF THE COURT
This is a petition for allowance of an appeal from the Superior Court’s per curiam affirmance of the denial *87 without a hearing of petitioner’s second petition filed pursuant to the Post Conviction Hearing Act. * In that petition defendant attacked as involuntary his plea of guilty to charges of conspiracy, assault with intent to kill and robbery entered on November 11, 1967. Petitioner also alleged a denial of effective assistance of counsel both at an earlier evidentiary hearing held to determine the voluntariness of his plea and on the appeal therefrom. The trial court denied petitioner’s second petition on the ground that the voluntariness of the plea had been finally litigated in the earlier proceeding, but without holding a hearing to determine whether petitioner had the benefit of competent counsel in that proceeding.
Since an issue may not be finally litigated or waived in a proceeding in which the defendant has been denied effective assistance of counsel, see
Commonwealth v. Via,
This petition for allowance of appeal is granted, the order of the Superior Court is vacated and the case is remanded to the Court of Common Pleas of Lancaster County for further proceedings consistent with this opinion.
