People v. Prather
979 N.E.2d 540
Ill. App. Ct.2012Background
- People v. Prather involves aggravated battery of a pregnant victim; multiple counts aggregate from May 31, 2011 incident.
- State moved in limine to admit BR’s testimony that she used a home pregnancy test and showed the positive result to Prather.
- Trial court excluded the BR testimony absent the test device itself, citing Frye concerns and lack of foundation.
- State sought to prove only notice/awareness, not the truth that BR was pregnant; court raised hearsay/foundation issues.
- On appeal, State argued Frye did not apply because testimony was to prove knowledge, not pregnancy; court disagreed with exclusion.
- Appellate court reverses and remands, concluding the ruling lacked proper legal basis for excluding the testimony.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility to prove notice only | Prather argues BR’s test result shows notice, not truth. | Prather contends reliability/frye concerns and foundation require exclusion. | Admissible to prove notice; not barred as hearsay; remand for proceedings. |
| Frye applicability to home pregnancy test | Frye not required since not proving pregnancy as fact, only knowledge. | Frye grounds apply to test reliability even for nonexperts. | Frye not needed; home pregnancy tests not novel; no Frye hearing required. |
| Foundation requirement for device vs. testimony | Testimony about result and display suffices to show notice; device not necessary. | Foundation required if proving a substantive fact or reliability of the test. | Foundation not required here; testimony relevant to notice is admissible without device. |
