Comment: Preface to Comments
The original Comments to the Pennsylvania Rules of Evidence were prepared by the Ad Hoc Committee on Evidence. The Comments accompanied the Pennsylvania Rules of Evidence that were adopted by the Pennsylvania Supreme Court on May 8, 1998. The Pennsylvania Rules of Evidence closely followed the format, language, and style of the Federal Rules of Evidence, but the guiding principle was to preserve the Pennsylvania law of evidence. The original Comments reflected this approach by identifying the Pennsylvania sources of the law. The original Comments also compared the Pennsylvania Rules to the Federal Rules for the convenience of the Bench and Bar.
The Federal Rules of Evidence were amended effective December 1, 2011. The goal of the Federal amendments was to make the rules more easily understood and to make the format and terminology more consistent, but to leave the substantive content unchanged. The Pennsylvania Rules of Evidence were rescinded and replaced on January 17, 2013, and become effective on March 18, 2013. They closely follow the format, language, and style of the amended Federal Rules of Evidence. The goal of the Pennsylvania Supreme Court’s rescission and replacement of the Pennsylvania Rules of Evidence was likewise to make its rules more easily understood and to make the format and terminology more consistent, but to leave the substantive content unchanged. Once again, the guiding principle is to preserve the Pennsylvania law of evidence.
These Comments are prepared by the Pennsylvania Supreme Court’s Committee on Rules of Evidence for the convenience of the Bench and Bar. The Comments have not been adopted by the Supreme Court and it is not intended that they have precedential significance.
Comment to Rule 101 A principal goal of these rules is to construct a comprehensive code of evidence governing court proceedings in the Commonwealth of Pennsylvania. However, these rules cannot be all-inclusive. Some of our law of evidence is governed by the Constitutions of the United States and of Pennsylvania. Some is governed by statute. Some evidentiary rules are contained in the Rules of Civil and Criminal Procedure and the rules governing proceedings before courts of limited jurisdiction. Traditionally, our courts have not applied the law of evidence in its full rigor in proceedings such as preliminary hearings, bail hearings, grand jury proceedings, sentencing hearings, parole and probation hearings, extradition or rendition hearings, and others. Traditional rules of evidence have also been relaxed to some extent in custody matters, see, e.g., Pa.R.C.P. No. 1915.11(b) (court interrogation of a child), and other domestic relations matters, see, e.g., Pa.R.C.P. No. 1930.3 (testimony by electronic means).
Decisional law is applicable to some evidentiary issues not covered by these rules. This would include for example, the corpus delicti rule, see Commonwealth v. Fears, 575 Pa. 281, 836 A.2d 52 (2003); the collateral source rule, see Boudwin v. Yellow Cab Co., 410 Pa. 31, 188 A.2d 259 (1963); and the parol evidence rule, see Yocca v. Pittsburgh Steelers Sports, Inc., 578 Pa. 479, 854 A.2d 425 (2004). The Pennsylvania Rules of Evidence are not intended to supersede these other provisions of law unless they do so expressly or by necessary implication.
These rules are applicable in the courts of the Commonwealth of Pennsylvania’s unified judicial system. In some respects, these rules are applicable in administrative proceedings. See, e.g., Gibson v. W.C.A.B., 580 Pa. 470, 861 A.2d 938 (2004) (evidentiary rules 602, 701 and 702 applicable in agency proceedings in general, including Workers’ Compensation proceedings). These rules are also applicable in compulsory arbitration hearings, with specific exceptions relating to the admissibility of certain written evidence and official documents. See Pa.R.C.P. No. 1305.
