73 F.4th 185
3rd Cir.2023Background
- In Oct. 2006 Mervilus was arrested and charged with robbery and aggravated assault after a victim identified others; he agreed to a stipulated polygraph whose results would be admissible if administered by a qualified examiner.
- Union County selected Detective John Kaminskas, its only certified polygraphist, who used the non‑standard, heavily subjective “Arther Method” (containing biased and unvalidated indicia).
- During the exam Kaminskas repeatedly pressured Mervilus to change an answer to question R3K; R3K was the only relevant question showing a physiological ‘‘deception’’ signal and Kaminskas concluded Mervilus lied.
- The polygraph testimony was admitted at trial (per the stipulation), Mervilus was convicted and sentenced to 11 years, but the conviction was later reversed by the New Jersey Appellate Division; at retrial the polygraph was not used and Mervilus was acquitted.
- Mervilus sued under 42 U.S.C. § 1983 (fabrication of evidence against Kaminskas; Monell claims against Union County and failure‑to‑train/supervise claims against the chief). The District Court granted summary judgment for defendants.
- The Third Circuit vacated and remanded: it held there was sufficient evidence for a jury to find fabrication (bad faith includes recklessness) and that certain Monell theories against Union County could proceed even if an individual officer is not held liable.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| 1) Sufficiency of evidence to try fabrication claim against Kaminskas | Mervilus: Kaminskas knowingly or recklessly fabricated the polygraph (used a discredited method, used biased techniques, pressured answer change, reached a conclusion not supported by data). | Kaminskas: At most used an inferior/controversial method and produced an incorrect or disputed result, not bad faith fabrication. | Vacated summary judgment; a reasonable jury could find Kaminskas acted willfully, knowingly, or with reckless disregard for the truth. |
| 2) Scope of "bad faith" required for fabrication claim | Mervilus: Bad faith includes deliberate falsehood or recklessness. | Defendants: Plaintiff must show knowing, intentional fabrication (arguing higher mens rea). | Court: Bad faith covers willful, knowing, or reckless fabrication; recklessness suffices. |
| 3) Qualified immunity for Kaminskas | Mervilus: Right against investigators’ fabrication was clearly established. | Kaminskas: Entitled to qualified immunity if no clearly established violation. | Court: Not entitled to qualified immunity because the right against fabrication was clearly established; remand to trial. |
| 4) Viability of Monell claims against Union County if Kaminskas not liable | Mervilus: County policies/practices (failure to train/supervise; custom of biased polygraphs) caused the constitutional harm and can be liable even if officer is not. | County: Monell fails because no underlying constitutional violation by Kaminskas. | Court: County may be liable on failure‑to‑train/supervise theory even if Kaminskas is exonerated; municipal liability may survive non‑liability of individual officer (but theory alleging customary fabrication depends on officer culpability). |
