In Menze v. County of Otter Tail, Judge Tostrud dismissed Aaron O. Menze's fifth lawsuit challenging Otter Tail County's authority to collect property taxes, imposed a filing restriction barring him from bringing similar cases in federal court without a lawyer or court permission, and denied his request to stop the county from taxing his property.
Pro se litigants who repeatedly file the same dismissed claims in federal court, particularly those challenging state property tax assessments already adjudicated in state court. Also relevant to anyone seeking to understand the Rooker-Feldman doctrine, issue preclusion, Rule 11 sanctions, and filing restrictions in the District of Minnesota.
What happened
In Menze v. County of Otter Tail (Case No. 25-cv-1055), Aaron O. Menze, representing himself, sued Otter Tail County, its County Auditor Wayne Stein, and County Assessor Heather Jacobson, arguing that the county had no legal authority to assess or collect property taxes on his land because he never consented to being taxed. He sought a refund of more than $95,000 in taxes he claimed to have paid, additional damages exceeding $100,000, and an emergency order stopping the county from taxing him. This was his fifth lawsuit raising the same basic argument — the prior four cases were all dismissed by state and federal courts, which repeatedly found his claims to be without merit and legally frivolous.
The court found that Menze's claims were blocked by a legal rule called the Rooker-Feldman doctrine, which prevents federal district courts from reviewing or overturning decisions already made by state courts. Because a prior federal case (Menze IV) had already determined that federal courts lacked the power to hear Menze's property-tax challenge for this reason, the court applied a related rule called issue preclusion — meaning the same question cannot be relitigated — to bar the current lawsuit as well. The court also found that Menze waived his right to contest the dismissal by failing to respond to the defendants' motion to dismiss.
Judge Tostrud granted the motion to dismiss (without prejudice, meaning Menze is not permanently barred from filing in a court that has proper authority), granted the defendants' motion for sanctions in part, and denied Menze's request for a temporary restraining order. As a sanction under Federal Rule of Civil Procedure 11, which requires litigants to have a reasonable legal basis before filing suit, Judge Tostrud imposed a filing restriction: Menze may not file new cases in the District of Minnesota against these defendants or based on the same property-tax allegations unless he is represented by a licensed attorney or first obtains written permission from a federal judge in this district. The court declined to order Menze to pay the defendants' attorney's fees, finding that the filing restriction alone was sufficient to deter future frivolous filings.

Background and Prior Litigation
Plaintiff Aaron O. Menze, proceeding pro se (without an attorney), filed this lawsuit on March 21, 2025, as the fifth in a series of cases challenging Otter Tail County's authority to assess and collect property taxes on land he owns. His core legal theory is that the right to own property is absolute and that, because he never consented to being taxed, the county has no jurisdiction to tax him. He sued under 42 U.S.C. §§ 1983 and 1985(3) — federal civil rights statutes — and raised claims including breach of contract, violation of the Minnesota Government Data Practices Act, violation of the Freedom of Information Act, and various torts (fraudulent misrepresentation, conversion, negligence, and defamation). He sought return of more than $95,000 in taxes paid, damages exceeding $100,000, and an emergency court order (temporary restraining order) prohibiting the county from further tax assessment or collection.
The court detailed four prior cases: - Menze I (Otter Tail County District Court, 2022): Dismissed without prejudice for failure to state a claim. - Menze II (Otter Tail County District Court, 2023): Construed as a motion to reconsider Menze I and dismissed without prejudice. - Menze III (Otter Tail County District Court, 2023): Menze's challenge to a delinquent tax proceeding was rejected; the state court sustained all taxes and penalties, found Menze a frivolous litigant, and imposed a filing restriction requiring him to post $100 security before filing any related claims in that court. - Menze IV (U.S. District Court, D. Minn., 2024): Magistrate Judge Leo I. Brisbois recommended dismissal without prejudice based on the Rooker-Feldman doctrine (lack of subject-matter jurisdiction) and frivolousness. Chief Judge Patrick J. Schiltz adopted the recommendation in full on January 10, 2025. Menze did not appeal.
Motion to Dismiss Under Rule 12(b)(6)
Defendants moved to dismiss under Federal Rule of Civil Procedure 12(b)(6) (failure to state a claim upon which relief can be granted). Menze did not respond to the motion within the 21-day period required by local rules, which the court found constituted waiver — sufficient grounds alone to grant dismissal.
Beyond waiver, the court held that dismissal was independently required based on issue preclusion (a form of res judicata). Issue preclusion prevents a party from relitigating an issue already actually decided in prior litigation. The court analyzed the five elements under federal common law:
- Menze was a party to Menze IV. ✓
- The issue of subject-matter jurisdiction (specifically, whether the Rooker-Feldman doctrine barred the federal lawsuit) was involved in Menze IV. ✓
- That issue was actually litigated in Menze IV. ✓
- The Menze IV dismissal constituted a final and valid judgment on the jurisdictional question — the court acknowledged that while dismissals without prejudice ordinarily do not create a res judicata bar, dismissals for lack of subject-matter jurisdiction are given preclusive effect on the jurisdictional question specifically. ✓
- The jurisdictional determination was essential to the Menze IV judgment. ✓
The Rooker-Feldman doctrine bars federal district courts from hearing cases brought by state-court losers seeking review of state-court judgments. The court in Menze IV had found that Menze's complaint implicitly asked a federal court to overturn Minnesota state court decisions about the county's authority to tax his property. The current complaint raised the same claims and sought the same relief, so the same bar applied.
Because the dismissal was grounded in lack of subject-matter jurisdiction, the dismissal was entered without prejudice (not foreclosing Menze from filing in a court that does have proper jurisdiction, if one exists).
Rule 11 Sanctions
Defendants also moved for sanctions under Federal Rule of Civil Procedure 11, which requires that a party signing a pleading certify — after reasonable inquiry — that the legal contentions are warranted by existing law or a nonfrivolous argument for changing the law. Defendants sought: (1) an order requiring Menze to pay their attorney's fees; and (2) a filing restriction. Menze did not respond to the sanctions motion.
The court found a Rule 11 violation. It reasoned: - Three separate judges (Judge Judd in state court twice, Magistrate Judge Brisbois and Chief Judge Schiltz in federal court) had told Menze his claims were frivolous and without legal basis. - Menze did not appeal any of those rulings. - Menze's current complaint made no attempt to address the Rooker-Feldman or other deficiencies identified in Menze IV — he essentially refiled the same complaint. - Any reasonable person, even without legal training, would have known not to file this case.
The court granted the sanctions motion in part:
Filing restriction imposed
Menze is prohibited from filing new cases in the District of Minnesota against the named defendants or based on the same nucleus of operative facts as the five Menze cases, unless he is represented by counsel or obtains prior written authorization from a judicial officer of the district. The court found all four factors for imposing a filing restriction were met: (1) history of vexatious, duplicative litigation; (2) no objectively good-faith basis for the litigation; (3) needless expense to defendants and burden on the courts; and (4) a tailored restriction is the appropriate remedy.
Attorney's fees denied
The court declined to order Menze to pay defendants' fees, finding that the filing restriction would itself deter future frivolous filings and that a monetary award would serve only to punish rather than deter, which is not Rule 11's proper purpose.
Temporary Restraining Order
Menze's motion for a temporary restraining order to stop the county from assessing or collecting property taxes was denied.
