30 F.4th 276
5th Cir.2022Background
- In 1992 Mansfield was indicted for sexual misconduct with a child; his counsel filed a Brady motion and the state court ordered disclosure of exculpatory evidence before trial.
- Prosecutors interviewed the victim in May 1993 and recorded statements contradicting her earlier identification of Mansfield (e.g., saying she did not remember or that another child may have been involved).
- Four days before trial, prosecutors told Mansfield (during plea negotiations) the victim would be a strong witness and that corroborating physical evidence existed; they did not disclose the contradictory statements and the plea offer was revocable.
- Facing a likely life sentence if convicted at trial, Mansfield pled guilty to a lesser charge, served 120 days in jail, ten years’ probation, and registered as a sex offender.
- A 2016 state habeas court vacated Mansfield’s conviction, finding prosecutors lied to avoid disclosing exculpatory evidence; Mansfield then sued Williamson County under 42 U.S.C. § 1983, alleging the county’s closed-file policy caused the misconduct.
- The magistrate judge granted summary judgment for the County; the Fifth Circuit affirmed, holding Mansfield failed to show a Monell causal link and that Fifth Circuit precedent forecloses a Brady claim based on pretrial plea bargaining.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Williamson County policy (closed-file) was the moving force behind prosecutors’ misconduct (Monell causation) | Mansfield: County’s closed-file policy, set by DA Anderson, enabled withholding and thus caused prosecutors to lie during plea bargaining | Williamson Co.: No policy sufficient to show deliberate indifference or direct causal link; misconduct (if any) was the prosecutors’ independent action | Held: No. Mansfield failed to show the closed-file policy was the moving force or established the requisite causal pattern for Monell liability |
| Whether Brady requires disclosure of exculpatory evidence during plea bargaining | Mansfield: Brady should apply to pretrial plea negotiations; withholding exculpatory evidence induced an involuntary plea | Williamson Co.: Fifth Circuit precedent forecloses a Brady claim tied to guilty pleas; Brady focuses on trial integrity | Held: Brady claim based on pretrial plea is foreclosed in this Circuit; no Fourteenth Amendment violation established for plea-stage nondisclosure |
| Whether court needed to decide if prosecutors’ conduct violated Brady/due process on the facts | Mansfield: Prosecutors knowingly lied about contents of file contrary to documents they were ordered to produce | Williamson Co.: Even assuming wrongdoing, plaintiff still cannot show municipal liability or relief under Brady for pleas | Held: The court did not resolve the underlying Brady/due-process question because Mansfield failed on Monell causation and on the circuit’s rule limiting Brady to trial context |
