*345 OPINION OF THE COURT
In October of 1974 appellant, Charles John Oakes, was convicted by a jury for the second time of murder in the first degree in the beating death of Eleanor Sanchez. Post-verdict motions were denied by a court en banc and defendant was sentenced to imprisonment for life. This appeal followed. 1 It requires us to consider whether a court en banc, in passing upon post-verdict motions challenging the admissibility of certain evidence following a retrial of a criminal defendant, is bound by the post-trial ruling of a previous court en banc sitting after the first trial to the effect that the evidence in question was admissible. The court of common pleas felt that it was so bound. We disagree, and will remand to the trial court for renewed consideration of those portions of appellant’s post-trial motions which it declined to entertain.
The record discloses that on the morning of November 12, 1971, the lifeless body of Eleanor Sanchez was discovered in her home in Philadelphia. Based on information obtained at the scene of the crime, Charles Oakes was arrested at 10:45 A.M. the same morning. He remained in police custody until the time of his arraignment on murder charges some thirty-six hours later. During this period Oakes made three incriminating statements which, prior to his first trial in April of 1973, he moved to suppress on the ground that they were illegally obtained. The motion was denied and all three statements were introduced into evidence during the course of that trial, which resulted in a verdict of guilty of murder in the first degree. Oakes then filed post-trial motions alleging that the suppression court had erred in refusing to suppress the three statements. The court en *346 banc agreed with respect to the third statement and awarded a new trial. 2
Prior to retrial, Oakes sought to have the remaining two statements suppressed but the judge hearing that motion refused to consider the issue or to conduct a new suppression hearing. See
Commonwealth v. Harmon,
In refusing to consider appellant’s post-trial claims relating to the suppression of evidence, the second court en banc reasoned that it was without the power to overrule the previous court en banc since both courts were of equal authority. We disagree; while this consideration properly serves as a restraint in many situations, this is not one of them. 4
*347
Under our system, a defendant who has been convicted of a crime has the right to file timely motions for a new trial and in arrest of judgment, which motions are decided by a court en banc before final judgment may be entered.
See
Pa.R.Crim.P. 1128, and Comments thereto. The function of the court en banc is to review the rulings of the suppression hearing judge and the trial judge.
Commonwealth v. Youngblood,
The grant of a new trial wipes the slate clean of the former trial. As we stated in
Commonwealth
v.
Hart,
“ ‘When a court grants a new trial, the necessary effect thereof is to set aside the prior judgment and leave the case as though no trial had been held . . . . By the operation of an order granting a new trial, the cause, in contemplation of law, is precisely in the same condition as if no previous trial had been held.’ ”
See
Andrews v. Jackson,
Holding as we do serves not only the immediate interest of the defendant but also the interest of facilitating effective appellate review. See
Commonwealth v. Reid,
Judgment of sentence vacated and case remanded for further proceedings consistent with this opinion.
Notes
. This Court has jurisdiction pursuant to Section 202(1) of the Appellate Court Jurisdiction Act of 1970, Act of July 31, 1970, P.L. 673, No. 223, Art. II, § 202(1), 17 P.S. § 211.202(1) (Supp. 1977-78), since superseded by Section 722(3) of the Judicial Code, 42 Pa.C.S. § 722(3) (effective June 28, 1978).
. Specifically, the court ordered that all statements obtained from the defendant subsequent to 12:20 A.M. on the morning of November 13, 1971, were to be suppressed. The reasons for the ruling do not appear of record and the Commonwealth did not appeal the decision. See
Commonwealth v. Youngblood,
. Also at issue was the suppression court’s ruling that certain physical evidence was properly seized during a search of appellant’s residence.
. Because of our disposition of the case, it is unnecessary to reach the merits of appellant’s other contentions to the effect that (1) a defendant, upon the grant of a new trial, is entitled to relitigate issues before a new suppression court; (2) certain physical evidence was seized from appellant's home upon search warrants executed without probable cause; (3) the statements introduced at trial were inadmissible because (a) involuntary, (b) obtained in violation of Pa.R. *347 Crim.P. 118 (now Rule 130), and (c) the fruit of an illegal arrest; (4) the trial court, in its charge to the jury, impermissibly commented upon the evidence; and (5) the trial court erred in giving a modified “Allen charge” to the jury.
. Because the order of the first court en banc granted a new trial, its determination that the first two inculpatory statements given by Oakes were admissible was interlocutory in nature and not then appealable by the defendant.
