210 Pa. Code § 1314
Within 14 days after service of a petition for permission to appeal an adverse party may file an answer. The answer shall be deemed filed on the date of mailing if first class, express, or priority United States Postal Service mail is utilized. The answer need not be set forth in numbered paragraphs in the manner of a pleading, shall set forth any procedural, substantive, or other argument or ground why the interlocutory order involved should not be reviewed by the appellate court, and shall comply with Pa.R.A.P. 1312(a)(7) (content of petition for permission to appeal). An answer to a petition for permission to appeal shall contain the certificate of compliance required by Pa.R.A.P. 127. No separate motion to dismiss a petition for permission to appeal will be received. A party entitled to file an answer under this rule who does not intend to do so shall, within the time fixed by these rules for filing an answer, file a letter stating that an answer to the petition for permission to appeal will not be filed. The failure to file an answer will not be construed as concurrence in the request for permission to appeal.
