704 F.Supp.3d 961
D. Minn.2023Background
- In 2021 Bloomington PD investigated a series of crimes with Walmart surveillance images of suspects; Hennepin County CISA analysts (Does 11–20) became involved in identification efforts.
- Hennepin County’s facial-recognition Training Manual forbids using the technology to “positively identify an individual” and requires independent verification.
- CISA analysts or Detective Andrew Risdall identified Kylese Perryman as a suspect; Risdall later arrested Perryman after receiving identifying information from Hennepin County.
- Perryman alleges the identification was erroneous (later characterized by Hennepin as a facial-recognition error), that exculpatory evidence was available, and that charges were not dropped for 52 days.
- Perryman sued Hennepin County under 42 U.S.C. § 1983 (false arrest, failure to train, civil conspiracy), for state-law false arrest, and for violation of the Minnesota Constitution. Hennepin moved to dismiss.
- The Court granted dismissal with prejudice of the § 1983 claims and the Minnesota Constitution claim, denied dismissal of the state-law false arrest tort claim (it survives).
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Municipal liability based on an official policy (Monell) | Hennepin breached its own facial-recognition policy by relying on software for a positive ID | No municipal policy caused the constitutional violation; the Training Manual forbids positive IDs | Dismissed — plaintiff failed to plead an unconstitutional official policy |
| Municipal liability based on custom | CISA analysts’ use of facial-recognition reflects an unofficial, widespread practice | Single incident (Perryman’s arrest) cannot show a custom or practice with force of law | Dismissed — single incident insufficient to plausibly allege a custom |
| Failure to train / deliberate indifference | Hennepin’s training was inadequate regarding facial-recognition, causing constitutional injury | Training manual existed with clear prohibitions; no pattern or notice to show deliberate indifference | Dismissed — no pattern and not the rare “so obvious” training deficiency to establish deliberate indifference |
| Section 1983 civil conspiracy by the County | County (through analysts) conspired with others to deprive Perryman of rights | A municipality cannot be liable under § 1983 on respondeat superior; Monell standards apply to conspiracy claims | Dismissed — plaintiff did not allege County-level policy, custom, or action by final policymakers |
| State-law false arrest tort | Hennepin instigated arrest by identifying Perryman via CISA/facial recognition | County did not make the arrest and contends immunity/vicarious defenses apply | Survives — plausible that County instigated/proximately caused arrest; ministerial-policy allegation defeats official-immunity at this stage |
| Minnesota Constitution (Art. I, §10) claim | Seeks relief for constitutional violation (injunctive/damages) | No private statutory cause of action; remedy overlaps with § 1983 | Dismissed — no independent federal remedy; relief is coextensive with § 1983 which was not plausibly alleged |
