This is an appeal from the judgment of sentence of the Court of Common Pleas, Criminal Division, of the 59th Judicial District, Elk County Branch, by the defendant-appellant, Rickey A. Antonucci, following conviction in a non-jury trial of Reckless Driving and Operating a Motor Vehicle while under the Influence of Intoxicating Liquors; and from the denial of Post-Trial Motions.
Appellant alleges, inter alia, that the lower court erred in granting the Commonwealth’s Petition for an Extension of Time to commence trial. We agree and therefore reverse Appellant’s conviction and order that he be discharged.
The criminal complaint in this case was filed on October 30, 1976, charging the Appellant with Reckless Driving and Driving under the Influence. On April 27, 1977, the Commonwealth filed a Petition for an Extension of Time to *537 commence Trial, this was one day before the 180 days would have expired. The Petition filed by the Commonwealth alleged that despite “due diligence” by the Commonwealth, defendant’s trial could not be commenced within 180 days after the complaint had been filed. A hearing on the Petition was held on May 2, 1977 and the court by Order of the same day, granted the Commonwealth’s Petition.
Under
Commonwealth v. Mayfield,
(1) The “due diligence” of the prosecution .
Here, although a hearing was held on May 2, 1977, the record contains no notes of testimony and we are therefore unable to evaluate the Commonwealth’s proof as to its “due diligence”. Mere assertions of due diligence and unproven facts, do not establish cause for an extension under Rule 1100(c). See
Commonwealth v. Porter,
We are, therefore, required to reverse the Appellant’s conviction and order that he be discharged. 1
Notes
. Appellant also raises two other arguments for reversal but we need not consider those.
