Commonwealth, Aplt. v. Olivo, J.
127 A.3d 769
Pa.2015Background
- Defendant Jose Luis Olivo was charged in 2012 with multiple sexual‑offense counts involving a child; the Legislature’s § 5920 (effective for prosecutions filed on/after Aug. 28, 2012) authorized expert testimony on victim responses to sexual violence.
- Four days before trial Olivo moved in limine to bar Commonwealth experts under § 5920, arguing the statute unconstitutionally infringed the Supreme Court’s exclusive rulemaking power under Pa. Const. art. V, § 10(c) and conflicted with Commonwealth v. Dunkle.
- The trial court granted the motion and suspended § 5920 as unconstitutional; the Commonwealth appealed directly to the Pennsylvania Supreme Court.
- The Commonwealth (and amici) argued: evidentiary rules may be enacted by the legislature (Pa.R.E. 101 comment and Newman), § 5920 tracks Pa.R.E. 702, and Dunkle addressed admissibility under Frye and evidentiary rules rather than constitutional separation of powers.
- The Supreme Court reviewed the procedural/substantive distinction under Article V, § 10(c), analyzed precedent (Payne, McMullen), and held § 5920 is a statute governing admissibility (a rule of evidence) and is not an unconstitutional invasion of the Court’s rulemaking authority.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether 42 Pa.C.S. § 5920 unlawfully invades the Supreme Court’s exclusive rulemaking power under Art. V, § 10(c) | Olivo: § 5920 is procedural and thus an unconstitutional encroachment on the Court’s rulemaking authority | Commonwealth: Rules of evidence may be enacted by the legislature; § 5920 fits within evidentiary/statutory exceptions to exclusivity | Held: § 5920 is an evidentiary statute (substantive rule of evidence), not an unconstitutional procedural statute; statute upheld |
| Whether § 5920 conflicts with Commonwealth v. Dunkle (inadmissibility of generalized expert testimony about child sexual‑abuse responses) | Olivo: § 5920 attempts to overrule Dunkle and permit the same testimony Dunkle barred; must be overruled only by this Court | Commonwealth: Dunkle was an evidentiary admissibility decision (Frye/record‑based), not a constitutional rule precluding legislative enactment | Held: Dunkle was an evidentiary, fact‑driven admissibility ruling (largely Frye‑based); its dicta on presumption of innocence is not controlling for constitutional separation‑of‑powers analysis |
| Whether the statute is procedural (thus per se invalid) or substantive | Olivo: § 5920 alters courtroom procedure and how juries assess credibility; therefore procedural | Commonwealth: § 5920 authorizes admissibility (a substantive evidentiary rule) and does not prescribe court procedures or presentation methods | Held: § 5920 is substantive (authorizes admission of expert testimony) and does not dictate court procedures; therefore not per se unconstitutional |
| Whether legislative enactment of evidentiary rules is permissible generally | Olivo: Legislature cannot displace Court’s procedural domain; prior case law limits legislative power | Commonwealth: Newman and Pa.R.E. 101 comment acknowledge statutes can govern evidentiary matters | Held: Court reaffirms that legislature may enact evidentiary rules (subject to constitutional limits); § 5920 fits within that authority |
