The 30 day statute you reference (42 PaCSA sec. 5553) is applicable to summary vehicle offenses. It does not apply to a Disorderly Conduct citation. I believe the applicable limitation period is 2 years per 42 PaCSA sec. 5552(a). The only recourse as it concerns the circumstances of the filing of the citation (as it was not issued at the time of the alleged offense) would be to allege violation of Pa. Rules of Criminal Procedure 410 and 109. Not a strong argument unless you can (1) establish improper filing in violation of Rule 410 and (2) prejudice under Rule 109. A difficult argument to make, at least around my parts of PA. Hope this helps.
