Appellant was convicted on September 20, 1972, and judgment of sentence imposed of seven and one-half {7lA) to fifteen (15) years imprisonment. His direct appeal was dismissed as untimely filed.
On November 9, 1973, appellant filed his first petition initiated under the Post Conviction Hearing Act1 requesting permission to file a direct appeal nunc pro tunc. The court below, after finding appellant’s appeal rights had been abridged by the untimely direct appeal, on February 20, 1974, granted the petition, and again a direct appeal was filed. We affirmed appellant’s judgment of sentence in Commonwealth v. Mitchell, 231 Pa.Super. 738, 326 A.2d 887 *47(1974). No petition for allowance of appeal was filed with the supreme court.
On October 31, 1975, appellant filed his second petition, this time in the form of a writ of habeas corpus, but in fact a petition seeking PCHA relief. This petition was denied on December 11, 1975, without a hearing or the appointment of counsel. No appeal was taken.
On December 18, 1975, appellant filed a PCHA petition, his third petition, and on March 8, 1976, another PCHA petition, his fourth petition. Both of these petitions were dismissed, again without a hearing or the appointment of counsel. No appeal was taken.
Appellant filed his fifth petition, again a PCHA petition, on August 24, 1976, and on December 2, 1976, the court below ordered a hearing and appointed counsel. The hearing, held on February 11, 1977, resulted in a modification of appellant’s sentence. No appeal was taken.
On April 14, 1977, appellant filed his sixth petition, also a PCHA petition, pro se, which was dismissed without appointment of counsel or hearing. The court below held that all of appellant’s claims had been finally litigated or waived. This dismissal order was entered June 3, 1977, and it is from that order that this appeal has been filed.
We agree with the court below and affirm. The issues appellant now seeks to raise are waived. The Post Conviction Hearing Act specifically provides that an issue is waived if the petitioner knowingly and understandingly failed to raise it, and it could have been raised in a prior proceeding actually initiated under the Act.2 Certainly, if not waived previously, the issues involved herein are waived by failure to raise them in the fourth PCHA3 petition filed by appellant on August 24, 1976, where counsel was appointed and a hearing held. Commonwealth v. Williams, 437 Pa. 526, 263 A.2d 127 (1970). As in Williams, this appellant had a hearing with counsel present, did not raise the claim he *48asserts today, and does not allege any extraordinary circumstances or changes in the law. He is therefore not entitled to relief because he has waived his right to litigate this claim.
The order of the court below is affirmed.
