In the instant appeal from his conviction for aggravated assault, for which he received a sentence of five to ten years imprisonment, appellant argues that he was denied his right to a speedy trial pursuant to Pa.R.Crim.P., Rule 1100. 1 We agree and will reverse.
On January 26, 1975, a written complaint was filed charging appellant with aggravated assault. Following his waiver of a preliminary hearing, a York County grand jury indicted appellant on that charge on April 22, 1975. By June of 1975 the Commonwealth realized that appellant could not be tried until the August session of criminal court because of a scheduling difficulty which could carry the case beyond the 180 days permitted for bringing appellant to trial. The last day of the August session was August 25, 1975. Pa.R.Crim.P., Rule 1100(a)(2). Hence, on June 12, 1975, the Commonwealth filed a timely petition for an extension of time pursuant to Rule 1100(c), alleging generally that the Commonwealth’s backlog of cases prevented *108 appellant’s case from reaching the grand jury prior to April 22,1975, which in turn precluded appellant’s case from going on trial earlier than August. The court granted the Commonwealth’s petition.
During the August trial session the Commonwealth again encountered difficulty in bringing appellant to trial, this time because the Commonwealth could not locate its victim, who was to be the principal witness at the trial. Therefore, on August 28, 1975, the Commonwealth formally requested another extension of time to bring appellant to trial. Following a hearing on the petition this extension was granted the Commonwealth over appellant’s objection. Appellant never filed a motion to dismiss pursuant to Rule 1100(f); and, on September 10,1975, he was tried and found guilty of aggravated assault.
The first question we must address is whether appellant waived his right to raise an alleged violation of Rule 1100 on appeal because he failed to file a motion to dismiss pursuant to Rule 1100(f). This issue was first raised in this court in
Commonwealth v. Sprankle,
At first it looked as if the Supreme Court would follow proposed course in the
Sprankle
dissenting opinion and establish a blanket rule requiring a motion to dismiss in every case in which a Rule 1100 violation is claimed on appeal. In
Commonwealth v. Wallace,
Most recently, however, the Supreme Court had the opportunity to review
Wallace
and substantially limited its applicability. In
Commonwealth
v.
Coleman,
“While an accused must normally file a pretrial motion to dismiss to preserve a claim, we believe appellee in the instant case preserved the issue by opposing the Commonwealth’s petition for an extension of time. By so doing, the court is put on notice that an accused can challenge that court’s finding of due diligence on the part of the *110 Commonwealth. We can thus find no waiver by Coleman of his rights under Rule 1100.” Commonwealth v. Coleman, 477 Pa. at 408,383 A.2d at 1272 .
Applying Coleman to the facts of the instant case, we find that appellant has properly raised the issue of the alleged violation of his rights under Rule 1100. 5 In this case as in Coleman appellant argues that the court below erred in granting the Commonwealth an extension of time, because the Commonwealth failed to demonstrate it had been duly diligent. The court having once had the opportunity to hear the evidence on this claim and rule on appellant’s argument prior to trial, nothing of substance could have been gained by appellant’s filing a Rule 1100(f) motion to dismiss pro forma. Therefore, the issue has not been waived.
Turning to the merits of appellant’s claim, we find that the court below abused its discretion in granting the Commonwealth’s petition for an extension of time on August 28, 1975. In pertinent part Rule 1100(c) provides that an application for an extension of time “shall be granted only if trial cannot be commenced within the prescribed period despite due diligence by the Commonwealth.” Furthermore, in order to justify an extension of time to try the defendant the Commonwealth has the burden of proving it exercised due diligence.
Commonwealth v. Smith, 477
Pa. 424,
Judgment of sentence is reversed and appellant is discharged.
Notes
. Because of our disposition of appellant’s speedy tried claim, we need not reach his additional contention that his sentence was - excessive.

Commonwealth v. Dandy,
. Jones, former C. J. and Pomeroy, J., did not participate in the consideration or decision of this case.
.
Commonwealth v. Coleman,
. We recognize that the voting in Coleman was fragmented among the six Justices. However, Mr. Justice Roberts’ concurring opinion which Mr. Justice Manderino joined makes clear that at least two other Justices would reach the merits of appellant’s claim. Thus, an absolute majority of the Supreme Court would not have applied Wallace as a bar to reviewing the merits of Coleman’s Rule 1100 claim.
