This appeal presents yet another new and very narrow question for decision under Pa.R.Crim.P. 1100. Where the action is instituted against a juvenile by a delinquency petition and subsequently certified to the Criminal Division of a Court of Common Pleas for full criminal trial, when does the allowable period of 180 days under Pa.R.Crim.P. 1100 start for purposes of insuring prompt trial? The lower court answered this question by starting the time on the date of filing the delinquency petition and granted appellee’s petition to dismiss and discharged appellee. We reverse.
On February 7, 1975, the delinquency petition was filed in the lower court alleging that appellee was involved in a series of burglaries in Bucks County. Appellee requested that the case be certified to the Criminal Division for adult proceedings. On March 31, 1975, a hearing was held on this petition and appellee’s petition was granted. The case was transferred on that date. On May 30, 1975, appellee was indicted. His case was listed for trial on June 16, 1975. Trial, however, was continued because of the lack of available court rooms.
*166On July 24, 1975, the Commonwealth petitioned for an extension of time pursuant to Pa.R.Crim.P. 1100(c) and a hearing on said petition was scheduled for August 11, 1975. On August 8, 1975, appellee, claiming the 180 day period commenced on February 7, 1975, and hence expired on August 6, 1975, filed a petition to dismiss pursuant to Pa.R.Crim.P. 1100(f). On August 11, 1975, after a hearing on both petitions, the lower court denied the Commonwealth’s petition to extend and granted the appellee’s petition to dismiss.
We need not decide whether or not the lower court was correct in denying the Commonwealth’s petition for extension since we hold that the lower court did err in considering the delinquency petition as the starting point for computation of the 180 day period under Pa.R.Crim. P. 1100. The Supreme Court of Pennsylvania has clearly indicated to the contrary in Pa.R.Crim.P. 1(a) by excluding juvenile proceedings from the ambit of the Pennsylvania Rules of Criminal Procedure. Indeed, a major purpose for the establishment of specialized juvenile proceedings was to protect juveniles from the full thrust of adult criminal justice.
As a basis for its decision, the lower court places great reliance upon Geiger Appeal, 454 Pa. 51, 309 A.2d 559 (1973). We agree that the Geiger decision is important to the resolution of the problem; however, as we interpret Geiger, it in fact supports our decision to reverse.
The Pennsylvania Supreme Court in Geiger, supra at 56, 309 A,2d at 562 quoting Pa.R.Crim.P. 1(a), clearly recognizes that:
“Unless otherwise specifically provided, these rules shall not apply to juvenile or domestic proceedings nor to summary cases in Philadelphia County.”
The court continues at page 57, 309 A.2d at page 563:
“We think it clear that the Criminal Rules apply until the point at which the powers of the Juvenile Court come into play under the Juvenile Court Law.”
*167Although the situation presented in this appeal is a 'matter of first impression in this Commonwealth and is the reverse of the Geiger situation, we believe that the rationale of Geiger supports a holding that the Pennsylvania Rules of Criminal Procedure do not apply until the point at which the powers of the Criminal Court come into play. And, this holding is given added impetus when it is the juvenile that requests the Juvenile Court to certify the action to Criminal Court, as appellee did in the case before us.
It is true that the comment to Pa.R.Crim.P. 1100 states:
“For the purpose of this Rule only, it is intended that ‘complaint’ also includes special documents used in lieu of a complaint to initiate criminal proceedings in extraordinary circumstances.”
However, we hold that a delinquency petition and any subsequent juvenile proceeding are not such “extraordinary circumstances” as contemplated by the Supreme Court as to justify the equating of the delinquency petition filed on February 7, 1975, with the filing of the complaint, where, as here, the juvenile proceedings are certified to criminal court for trial.
The 180 day period under Pa.R.Crim.P. 1100 commences at that point when the case comes within the powers of the Criminal Court, and hence within the ambit of the Rules of Criminal Procedure. The Order of Transfer then starts the commencement of the 180 day time period. We recognize that this holding also does not clearly meet the challenge of “a written complaint” as stated in Pa.R.Crim.P. 1100(a). However, it does clearly meet the intent of the Supreme Court in excluding juvenile proceedings from the operation of the Rules of Criminal Proceedings, and on balance insures to defendants the right to a speedy trial.
Since the Order certifying this case was entered on March 31, 1975, the Commonwealth was obligated to *168commence appellee’s trial prior to September 27, 1975, and not August 6, 1975, as concluded by the lower court.
We therefore reverse the order of the lower court and remand the case for trial.
WATKINS, President Judge, concurs in the result. CERCONE, J., files a dissenting opinion.
