Pennsylvania Citation, Rule 14.5 is a state rule that governs the citation of legal authority in Pennsylvania. It is an important tool for legal research and argumentation in the state. This rule allows legal professionals to cite to relevant sources in a consistent and organized manner. Specifically, Rule 14.5 provides a method for citing to both primary and secondary legal sources, such as statutes, cases, court rules, and other legal materials. There are three types of citations that can be used under Rule 14.5: official citations, parallel citations, and unpublished citations. Official citations are the most authoritative and must be used for all Pennsylvania Supreme Court and Superior Court opinions. Parallel citations are used when citing other reported opinions and must include the official citation and a reporter citation. Unpublished citations are used for unpublished opinions, court orders, and other documents not reported in an official reporter.
