Katie Gatewood v. City of O'Fallon, Missouri, 70 F.4th 1076

Katie Gatewood, an O’Fallon, Missouri city council member, publicly opposed the mayor’s appointment of a police chief (Philip Dupuis) and pursued an independent inquiry that the City later found violated a municipal code provision.
The City Council initiated impeachment proceedings; Gatewood recorded a private conversation and publicly accused officials of felonies; Council convened a Board of Impeachment and proposed articles.
While impeachment was pending, Gatewood filed a federal civil-rights suit seeking injunctive relief; the district court initially abstained under Younger and later stayed the federal case pending state proceedings.
The City Council impeached and the mayor removed Gatewood; Gatewood did not seek judicial review in Missouri state court and the appeal period expired.
After lifting the stay, the district court dismissed Gatewood’s federal suit on claim-preclusion/exhaustion grounds for failing to pursue available state remedies, citing Huffman and Alleghany; Gatewood appealed, challenging the abstention and dismissal.
The Eighth Circuit affirmed, holding the abstention issue immaterial to the outcome and declining to consider arguments first raised in Gatewood’s reply brief; the dismissal was affirmed.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Younger abstention and a stay were improper or an exception allowed federal action while impeachment was pending	Gatewood: an exception to Younger applied so the federal court could act before state impeachment concluded	Defendants: Younger abstention applied and federal court should defer to ongoing state impeachment proceedings	Court: Abstention question was immaterial because the case was dismissed on other grounds; no change to outcome
Whether dismissal was proper because Gatewood failed to pursue available state judicial review (claim preclusion/exhaustion)	Gatewood: (on appeal) the dismissal was erroneous	Defendants: dismissal appropriate under Younger-related exhaustion principles and claim-preclusion cases (Huffman, Alleghany)	Court: Affirmed dismissal — failure to seek state appellate review precluded federal relief
Whether Gatewood may raise the dismissal argument on appeal for the first time in her reply brief	Gatewood: urged consideration despite raising it late	Defendants: too late; unfair prejudice and waived	Court: Declined to consider arguments first raised in the reply brief and affirmed for that reason as well
