In Menze v. County of Otter Tail, Judge Tostrud dismissed pro se plaintiff Aaron Menze's fifth identical property-tax challenge and imposed a filing restriction as a sanction.
Pro se litigants who repeatedly file the same claims after courts have dismissed them and expressly found them frivolous — particularly in cases involving challenges to local government taxing authority. The opinion illustrates how federal courts can use issue preclusion based on prior jurisdictional rulings and can impose filing restrictions under Rule 11 to prevent serial meritless filings.
What happened
In Menze v. County of Otter Tail, No. 25-cv-1055, pro se plaintiff Aaron O. Menze filed his fifth lawsuit arguing that Otter Tail County, Minnesota lacks authority to assess and collect property taxes on his land, claiming the county never obtained his consent to tax his property. He sought a refund of more than $95,000 in taxes he says he paid, damages exceeding $100,000, and a temporary restraining order to stop the county from taxing him going forward. His prior four lawsuits — three in state court and one in federal court — all raised the same theory and were all dismissed.
Defendants moved to dismiss the complaint for failure to state a claim and separately sought sanctions under the federal court rule requiring that filings have a legitimate legal or factual basis (Federal Rule of Civil Procedure 11). Mr. Menze did not respond to either motion. The court found his claims legally implausible and also precluded by the earlier federal dismissal: a prior federal court had ruled that the so-called Rooker-Feldman doctrine — which bars federal district courts from reviewing state-court judgments — prevented Mr. Menze from bringing his challenge in federal court, and that ruling bound this case as well. Three different judges across the four prior cases had told Mr. Menze his claims were frivolous, yet he filed the same claims again without addressing any of the identified problems.
Judge Eric C. Tostrud granted the motion to dismiss without prejudice, denied the temporary restraining order, and granted the sanctions motion in part. The judge imposed a filing restriction barring Mr. Menze from filing new cases in this federal district against the named defendants or based on the same property-tax allegations unless he is represented by a lawyer or first obtains written permission from a judge in the district. The judge declined to order Mr. Menze to pay the defendants' attorneys' fees, concluding that the filing restriction alone was sufficient to deter future misconduct and that a monetary award would serve only to punish rather than deter.

Background
Plaintiff Aaron O. Menze, representing himself, owns property in Otter Tail County, Minnesota. He believes that the county has no legal authority to assess or collect property taxes on his land because he never consented to taxation, and he claims that his right to own property is "absolute unless an obligation is entered into." His core legal theory is that Minnesota Statutes § 272.01 — which states that all real and personal property in the state is taxable unless exempt — cannot be applied to him without his consent.
This was Mr. Menze's fifth lawsuit raising the same basic theory: - Menze I (Otter Tail County District Court, 2022): Dismissed without prejudice by Judge Johnathan R. Judd 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): Arose from a delinquent tax proceeding. Judge Judd rejected Mr. Menze's claims on the merits, entered judgment for all taxes and penalties, denied Mr. Menze's motion to reconsider, and declared Mr. Menze a frivolous litigant — imposing a state-court filing restriction requiring him to post $100 security before filing any new property-tax claim. Mr. Menze did not appeal. - Menze IV (U.S. District Court, D. Minn., 2024): Dismissed without prejudice. Magistrate Judge Leo I. Brisbois found that the Rooker-Feldman doctrine (a rule that prevents federal district courts from reviewing or overturning state-court judgments) barred federal jurisdiction, and that the complaint was frivolous. Chief Judge Patrick J. Schiltz adopted the report and recommendation in full after de novo review. Mr. Menze did not appeal.
In this fifth action, filed March 21, 2025, Mr. Menze raised the same core issue. He sued under 42 U.S.C. §§ 1983 and 1985(3) (federal civil-rights statutes allowing suits against those acting under color of law), asserting breach of contract, violation of the Minnesota Government Data Practices Act, violation of the Freedom of Information Act, and the torts of fraudulent misrepresentation, conversion, negligence, and defamation. He also invoked multiple constitutional amendments. He sought a refund of taxes paid and damages exceeding $100,000, and filed a motion for a temporary restraining order to stop the defendants from assessing or collecting property taxes from him.
Defendants moved to dismiss under Federal Rule of Civil Procedure 12(b)(6) (failure to state a claim upon which relief can be granted) and separately sought sanctions under Federal Rule of Civil Procedure 11. Mr. Menze did not respond to either motion.
Motion to Dismiss
Waiver. The court first noted that under the District of Minnesota's Local Rules, Mr. Menze had 21 days to respond to the motion to dismiss and did not do so. Courts in this district treat a failure to respond as a waiver. Although Mr. Menze filed a letter on April 14, 2025, it addressed an alleged drafting error in his complaint rather than the motion to dismiss. The court stated the motion could be granted on waiver alone.
Issue Preclusion. Separately, the court granted dismissal on issue preclusion grounds (part of the doctrine collectively called res judicata — meaning a court's prior final judgment on an issue prevents re-litigation of that issue). The court applied five elements under federal common law:
- Mr. Menze was a party to Menze IV — satisfied.
- The issue of subject-matter jurisdiction (specifically, the Rooker-Feldman bar) was the same issue — satisfied.
- That issue was actually litigated in Menze IV — satisfied; Magistrate Judge Brisbois analyzed Rooker-Feldman in detail.
- The determination was a final and valid judgment — the court acknowledged that dismissals without prejudice and dismissals for lack of jurisdiction do not ordinarily create a res judicata bar on the merits, but the Eighth Circuit has held that such dismissals do have preclusive effect on the jurisdictional issue actually decided. The ruling in Menze IV that the federal court lacked subject-matter jurisdiction was final and valid as to that jurisdictional question.
- The jurisdictional determination was essential to the prior judgment — satisfied.
Because all five elements were met, the Rooker-Feldman ruling in Menze IV precluded Mr. Menze from relitigating federal subject-matter jurisdiction here. The court noted that because the dismissal is jurisdictional in character, it is without prejudice.
Rule 11 Sanctions
Federal Rule of Civil Procedure 11(b) requires anyone who signs and files a pleading to certify that the legal contentions are warranted by existing law or by a non-frivolous argument. This objective standard applies to self-represented (pro se) litigants as well as attorneys, though the reasonableness inquiry may account for the litigant's lack of legal training.
The court found Mr. Menze violated Rule 11(b). Key reasoning: - He filed essentially the same complaint that was dismissed in Menze IV without addressing the Rooker-Feldman problem the court had identified. - Three separate judges across prior proceedings had expressly told him his claims were frivolous and lacked any arguable basis in law or fact. - His complaint showed no indication that he engaged in any pre-filing inquiry into whether his claims had merit. - The court concluded that "any reasonable person — even someone with no legal training — would have known better than to file" this case.
Filing Restriction. Courts have discretion to impose filing restrictions on litigants who file non-meritorious actions for obviously malicious purposes and generally abuse the judicial process. The court considered four factors: 1. History of litigation — five lawsuits raising identical, discredited claims. 2. Objective good faith basis — none found. 3. Needless expense to defendants and burden on courts — yes. 4. Whether other sanctions would adequately protect — a tailored filing restriction was deemed sufficient.
The court imposed the following restriction: Mr. Menze may not file new cases in the U.S. District Court for the District of Minnesota against the named defendants (Otter Tail County, Wayne Stein, Heather Jacobson, and the relevant county officials in their official and individual capacities) or based on the same nucleus of operative facts as in any of his five cases, unless he is (a) represented by counsel or (b) obtains prior written authorization from a judicial officer of the district.
No Monetary Sanction. Although the court noted that a monetary sanction (attorneys' fees) might be warranted, it declined to impose one, reasoning that the filing restriction would itself deter future filings and that an attorneys' fee award would serve only to punish rather than deter — which is not the proper function of Rule 11 sanctions.
Temporary Restraining Order
Mr. Menze's motion for a temporary restraining order — which would have prohibited defendants from assessing or collecting property taxes from him — was denied.
Disposition
- Defendants' motion to dismiss is granted.
- Defendants' motion for sanctions is granted in part (filing restriction imposed; fee award denied).
- Filing restriction imposed on Mr. Menze as described above.
- Plaintiff's motion for a temporary restraining order is denied.
- The action is dismissed without prejudice.
