Civil RightsSection 1983Civil ProcedureSummary Judgment
In one sentence

In Duncan v. Duncan, Judge Menendez denied Chisago County's motion to pause the case for an immediate mid-case appeal of the court's earlier ruling that the county is liable for its sheriff's sexual abuse.

Who this affects

Local governments and county officials facing § 1983 civil-rights lawsuits, particularly those seeking to appeal mid-case rulings on Monell liability or 'under color of law' questions before trial. Also relevant to plaintiffs in civil-rights cases involving misconduct by high-ranking local officials such as sheriffs.

What happened

In Darcey Duncan v. Richard Duncan and Chisago County (No. 23-cv-646), Plaintiff Darcey Duncan sued the county sheriff and the county itself under federal civil-rights law after the sheriff sexually abused her while serving in his official role. The court had already ruled in an earlier order that the sheriff acted 'under color of law' (meaning he used his official position to commit the abuse) and that the county could be held liable under a legal doctrine called Monell liability, which allows a local government to be held responsible for a constitutional violation caused by one of its officials acting as a policymaker. The county asked the court to pause the case and allow an immediate appeal of those rulings before trial.

Under federal law, parties normally must wait until a final judgment before appealing, but a narrow exception allows a district court to certify certain legal questions for immediate appeal if: the question is a controlling pure question of law; there is substantial disagreement among courts about the answer; and an immediate appeal would meaningfully speed up the end of the case. The county argued both the 'under color of law' question and the Monell liability question qualified. The court disagreed on multiple grounds: both questions are deeply tied to the specific facts of this case rather than being 'pure' legal questions an appeals court could answer without reviewing the record, the county pointed to only one arguably conflicting case on the color-of-law issue, and settled binding precedent from the Eighth Circuit governed the Monell question.

Judge Katherine Menendez also found that an immediate appeal would not meaningfully shorten the litigation because a trial on damages is all that remains for the federal claims, and the court would likely keep the related state-law tort claims — on which it already ruled in Darcey's favor — regardless of what an appeals court did with the federal claims. For all these reasons, Judge Menendez denied the county's motion to certify the interlocutory appeal.

Background

Plaintiff Darcey Duncan brought this action under 42 U.S.C. § 1983 — the federal civil-rights statute that allows individuals to sue state or local officials who violated their constitutional rights — against Chisago County Sheriff Richard Duncan and Chisago County, alleging that Duncan sexually abused her while serving as sheriff. She asserted two primary theories of liability: (1) a Monell claim (from Monell v. Dep't of Soc. Servs., 436 U.S. 658 (1978)) seeking to hold the county liable for Duncan's constitutional violations on the ground that his conduct, as the county's top law-enforcement policymaker, represented official county policy; and (2) state-law tort claims against Duncan, for which she argued the county was vicariously liable.

Prior Proceedings

On cross-motions for summary judgment, the court denied the county's motion, concluding that Duncan acted 'under color of law' (i.e., he used his official authority or position to commit the abuse) and that Monell liability attached to the county. The court separately denied a post-order request by the county to address vicarious liability for the state-law tort claims, finding that argument had not been properly raised. The court also granted summary judgment in Darcey's favor on those state-law claims. What remains for trial is a determination of damages on Darcey's federal claims.

The Motion at Issue

The county moved to certify two questions for interlocutory appeal under 28 U.S.C. § 1292(b), which allows a district court to authorize an immediate mid-case appeal of a non-final order in exceptional circumstances. The two questions were: (1) whether Duncan acted 'under color of state law' when he sexually abused Darcey; and (2) whether Duncan's conduct 'could fairly be said to represent official policy' of the county, as required for Monell liability.

Legal Standard for § 1292(b) Certification

Interlocutory appeals are disfavored as a narrow exception to the general rule requiring a single appeal after final judgment. The moving party bears a heavy burden of demonstrating that all three statutory elements are satisfied: (1) the order involves a controlling question of law; (2) there is substantial ground for difference of opinion on that question; and (3) an immediate appeal may materially advance the ultimate termination of the litigation. All three elements must be met; failure on any one is sufficient to deny certification.

Element 1 & 2: Controlling Question of Law / Substantial Grounds for Disagreement

Under Color of Law

The court acknowledged that the under-color-of-law issue is 'controlling' in the sense that its resolution could materially affect the outcome of the case — it is a threshold requirement for § 1983 liability. However, the court found it is not a 'pure' question of law as required for § 1292(b) certification. Whether an officer acted under color of law is a fact-intensive inquiry requiring engagement with the specific record. The court cited Ahrenholz v. Bd. of Trs. of the Univ. of Ill., 219 F.3d 674, 676 (7th Cir. 2000), for the principle that a certifiable legal question must be one the court of appeals could decide 'quickly and cleanly without having to study the record.'

On the substantial-disagreement element, the county cited only one Eighth Circuit case — Roe v. Humke, 128 F.3d 1213 (8th Cir. 1997) — as allegedly reaching a different conclusion on similar facts. The court found that a single case does not establish that controlling law is unclear, and in any event the court had already distinguished Roe in its summary-judgment order. The court reiterated that 'a party's strong disagreement with the Court's ruling is not sufficient for there to be a substantial ground for difference.' Couch v. Telescope Inc., 611 F.3d 629, 633 (9th Cir. 2010).

Monell Liability

The court characterized the Monell question as a 'closer call.' It acknowledged that the question of when a single official's decision constitutes official municipal policy appears to be the subject of differing views across federal circuits. However, it found that in denying the county's summary-judgment motion, it had largely applied binding Eighth Circuit precedent — specifically Bolderson v. City of Wentzville, 840 F.3d 982 (8th Cir. 2016) — which squarely addressed when a single decision by a municipal authority can constitute official policy under Pembaur v. City of Cincinnati, 475 U.S. 469 (1986). The county's argument that the Eighth Circuit has not directly addressed policymaker liability in this specific context was unavailing; a dearth of on-point cases does not, by itself, constitute substantial ground for difference of opinion. See Union Cnty. v. Piper Jaffray & Co., 525 F.3d 643, 647 (8th Cir. 2008). As with the color-of-law issue, the court also found that the Monell question is not a pure legal question separable from the factual record.

Element 3: Material Advancement of Termination of Litigation

The court found the third element also unsatisfied. All that remains on the federal claims is a damages trial. Even if the Eighth Circuit reversed the county's Monell liability on appeal, the court indicated it would likely retain jurisdiction over the state-law tort claims — on which it has already ruled in Darcey's favor at summary judgment — because considerations of judicial economy, fairness, and the like support keeping those claims in federal court. The court cited Eddings v. City of Hot Springs, 323 F.3d 596 (8th Cir. 2003), and noted the discretionary nature of supplemental jurisdiction over state claims. Because the case 'will be conducted in substantially the same manner regardless of [the appellate court's] decision,' an immediate appeal would provide only minimal efficiency gains and therefore cannot be said to materially advance termination of the litigation.

Disposition

The court denied the county's Motion to Certify Interlocutory Appeal (Dkt. No. 136) in its entirety.
