Penn. C.C.R.C.P. 206.5
When an answer has been timely filed and the issue raised by the petition, motion or preliminary objection is ripe for consideration, pursuant to the provisions of Pa.R.C.P. No. 206.7, any party may file a praecipe for determination in the form described by C.C.R.C.P. No. 206.6 along with a supporting brief. If a petitioner files a praecipe for determination on petition and answer, all averments of fact responsive to the petition and properly pleaded in the answer shall be deemed admitted. If a respondent orders the matter for argument on petition and answer without having taken depositions or such other discovery as the court may have allowed, then all averments of fact properly pleaded in the petition shall be deemed admitted for the purposes of the rule, unless the petitioner shall have failed to take depositions or such other discovery as the court may have allowed within the time required, in which event the petition shall be decided on petition and answer and all averments of fact responsive to the petition and properly pleaded in the answer, shall be deemed admitted pursuant to Pa.R.C.P. No. 206.7(c). Responsive briefs shall be filed within fifteen (15) days of the filing of the praecipe for determination. The assigned judge may, at his or her discretion, extend the time for filing briefs.
