dissenting:
After a jury trial on February 10, 1975, appellant was convicted of attempted burglary1 and loitering and prowling at night time.2 Post-trial motions for a new trial and in arrest of judgment were denied, and appellant was sentenced to a term of imprisonment totaling a minimum of five years and a maximum of ten years.
On appeal, appellant contends that he was denied his right to a speedy trial under Pa.R.Crim.P. 1100(a)(1),3 and that as a result, he should be discharged. I agree with appellant’s contention, and therefore respectfully dissent.
The facts pertinent to our consideration of appellant’s Rule 1100 claim are as follows. A complaint was filed against appellant on July 11, 1973, charging him with the offenses of which he was subsequently convicted. On February 21, 1974, the date on which trial was to commence, appellant’s counsel was unable to attend due to a conflict in his schedule, to-wit, he was trying another case on that day. The trial in that other case lasted only one day, terminating the afternoon of February 21. During the afternoon of February 21, President Judge Edward H. Carney dismissed the entire jury panel, thereby rendering it impossible to select any more juries to try cases during the February trial term. The next trial term was in May, and appellant’s trial was rescheduled for May 15,1974. Appellant filed a motion to dismiss under Rule 1100(f)4 on May 9, 1974,5 and the case *478was continued pending disposition of appellant’s petition. Appellant’s petition was not denied until January 20, 1975, and trial subsequently commenced on February 10, 1975.
*477“At any time before trial, the defendant or his attorney may apply to the court for an order dismissing the charges with prejudice on the ground that this Rule has been violated. A copy of such application shall be served upon the attorney for the Commonwealth, who shall also have the right to be heard thereon. *478Any order granting such application shall dismiss the charges with prejudice and discharge the defendant.”
Under Rule 1100(a)(1), the Commonwealth had 270 days or until April 7, 1974, to try appellant. The Commonwealth contends that the rescheduling to May 15, 1974, was caused by the unavailability of appellant’s counsel, and therefore, that the period of time from February 21, 1974, to May 15, 1974, should be excluded under Rule 1100(d)(1) from calculation of the run time for Rule 1100 purposes. I disagree.
Under 1100(d), “[i]n determining the period for commencement of trial, there shall be excluded therefrom such period of delay at any stage of the proceedings as results from: (1) the unavailability of the defendant or his attorney . . ” In the instant case, the trial was rescheduled for May 15, because the .jury panel had been dismissed; as a result, no further jury trials could have been conducted during the February trial term. This scheduling difficulty is more properly of the nature of a judicial delay than of a delay due to counsel’s unavailability. The cases of our supreme court have made clear that scheduling difficulties may provide the basis for the request of an extension pursuant to Section (c) of the Rule, but do not provide the basis for the exclusion of time under Section (d)(1). Commonwealth v. Morgan, 484 Pa. 128, 398 A.2d 972 (1979); Commonwealth v. Shelton, 469 Pa. 8, 364 A.2d 694 (1976).
“In Shelton, supra, we made it clear that a request for an extension based upon ‘judicial delay’ could not provide the basis for an exclusion under Section (d). ‘Since we have determined that “judicial delay” may serve as a basis for the granting for an extension pursuant to Section (c), the substantial impairment allegedly created by the dicta in *479the Superior Court’s majority opinion to the Commonwealth’s right to effectuate a prosecution is not now a valid consideration in determining whether “judicial delay” should be impliedly excluded from the computation of the mandatory period in which to commence trial. Since the impairment has been removed, “ . . . our rule provides the Commonwealth with an adequate procedural method to protect its right (to effectuate a prosecution), mainly by obtaining extensions under Section (c) of the rule . . . ” Commonwealth v. O’Shea, supra, 465 Pa. [491] at 497 n.7, 350 A.2d [872] 875 n.7. Therefore, as in O’Shea, supra, “ . . .we can perceive no reason to imply an additional exclusion.” [Commonwealth v. Shelton, supra, 469 Pa. at 18, 364 A.2d at 699]’ ” Commonwealth v. Morgan, supra, 484 Pa. at 126-127, 398 A.2d at 976.
In the instant case, the Commonwealth filed no petition for extension under the Rule. Thus, with the run time unaltered, the run date for Rule 1100 purposes was the 270th day from the July 11, 1973 complaint, i. e., April 7, 1974.6 Viewed in this light, appellant’s May 9, 1974 motion to dismiss was meritorious and should have been granted by the court below since trial did not commence before April 7.
Accordingly, I would vacate the judgment of sentence and order appellant discharged.
. 18 Pa.C.S. § 3502.
. 18 Pa.C.S. § 5506.
. Pa.R.Crim.P. 1100(a)(1) provides that “[t]rial in a court case in which a written complaint is filed against the defendant after June 30, 1973 but before July 1, 1974 shall commence no later than two hundred seventy (270) days from the date on which the complaint is filed.”
. Rule 1100(f) provides that:
. See note 5 on page 478.
. The factual situation presented in this case would also support a finding that the Commonwealth failed to exercise due diligence in making an effort “to reschedule the trial as quickly as circumstances permit.” See Commonwealth v. Morgan, supra, 484 Pa. at 127 n.5, 398 A.2d at 976 n.5.
