No. 20-2204 

LEO D. STOLLER and MICHAEL 

STOLLER, 

Plaintiffs-Appellants, 

v. 

WALWORTH COUNTY, et al., 

 Defendants-Appellees.

 Appeal from the United States District 

Court for the Eastern District of 

Wisconsin. 

No. 17-CV-1349-JPS 

J.P. Stadtmueller, 

Judge. 

O R D E R 

 This is the second time this lawsuit comes to us. In the first appeal, Christopher 

Stoller asserted that Walworth County and its officials violated state and federal law by 

relying on “sham,” inflated appraisals in order to reject as too low his bids on three taxdelinquent properties. We reinstated the suit, which had been dismissed for failure to 

state a claim, because Christopher was not given the opportunity to amend. Stoller v. 

Walworth Cty., 770 F. App’x 762 (7th Cir. May 30, 2019). On remand, after he and two 

other family members—who did not bid on the properties—added new claims and 

defendants, the district court entered judgment against them. Christopher is not a party 

to this new appeal, and the two other family members lack standing, so we affirm. 

 The facts are disputed; we recount the Stollers’ version to the extent the record 

supports it. Stampley v. Altom Transp., Inc., 958 F.3d 580, 585 (7th Cir. 2020). Christopher,

 We have agreed to decide the case without oral argument because the briefs and 

record adequately present the facts and legal arguments, and oral argument would not 

significantly aid the court. FED. R. APP. P. 34(a)(2)(C).

Michael, and Leo Stoller built a home in Walworth County, Wisconsin, on land owned 

by Christopher. The County told Christopher in 2017 that it had taken possession of 

three tax-delinquent properties bordering his land. At the County’s invitation, 

Christopher bid for each of those plots. His $2,500 bids fell far below the properties’ 

appraised values of $11,400, however. So, following a state statute requiring the 

rejection of bids under the appraised value of the land, WIS. STAT. § 75.69, the County 

rejected his bids and later sold the properties to different buyers. 

 Christopher and Michael sued. They alleged that the County and its officials 

violated the Racketeer Influenced and Corrupt Organizations Act, 18 U.S.C. §§ 1961–68, 

and several state laws by conspiring to inflate fraudulently the appraisal values of the 

tax-delinquent properties. The district court dismissed the complaint for failure to state 

a claim, but as mentioned above we remanded to allow the Stollers one chance to 

amend. Stoller, 770 F. App’x at 765. 

 On remand, Christopher and Michael amended their complaint to include Leo as 

a plaintiff and added several new claims. Among other theories, the Stollers now 

asserted that the state law governing the sale of tax-delinquent properties, WIS. STAT. 

§ 75.69, is unconstitutionally vague and violates the Takings, Due Process, and Equal 

Protection Clauses. They also named several new defendants, including the current 

owners of the plots that Christopher had bid on, the State of Wisconsin, and its 

governor. Lastly, they added an unrelated breach-of-contract claim against Lake Como 

Sanitary District for failing to extend sewer and water lines to Christopher’s property. 

Proceedings quickly became tangled. Some defendants moved for summary 

judgment, others asserted that the complaint failed to state claims, and the governor 

and the State never answered. The Stollers, meanwhile, dismissed some claims. Further, 

they asked for a default judgment against Walworth County officials, the governor, and 

the State, and moved to disqualify the defendants’ lawyers, asserting ethical conflicts. 

 Eventually, the district court entered judgment against the Stollers. To begin, no 

evidence suggested that Walworth County or its officials engaged in a pattern, let alone 

a single act, of racketeering, so the RICO claim failed, and no evidence showed that the 

Stollers suffered injuries traceable to these defendants on any other claim. Further, the 

court ruled, the Stollers had not properly served their complaint on the governor or the 

State, and the complaint stated no legal claim against those defendants or the current 

owners of the plots adjoining Christopher’s. Finally, no evidence showed an agreement 

between the Stollers and Lake Como Sanitary District. Having resolved all of the 

Stollers’ claims, the court denied their outstanding motions as moot.

 This appeal is fundamentally defective. Christopher—the sole bidder on the 

parcels—has earned himself a Mack bar since the first appeal in this case and, having 

failed to pay his outstanding sanctions, is not party to this one. Wilmington Tr., Nat’l 

Ass’n. v. Stoller, Nos. 19-2561 & 19-2591 (7th Cir. Dec. 23, 2019); see also Support Sys. Int’l, 

Inc. v. Mack, 45 F.3d 185, 186 (7th Cir. 1995). That leaves Leo and Michael, who did not 

bid on the properties. They generally assert that WIS. STAT. § 75.69 is unconstitutionally 

vague and that the County created harm by rejecting Christopher’s bids. But they lack 

standing to raise these claims. Any plaintiff invoking federal jurisdiction must establish 

a personal injury fairly traceable to the defendants’ conduct. Spokeo, Inc. v. Robins, 136 S. 

Ct. 1540, 1547 (2016); Lujan v. Defs. of Wildlife, 504 U.S. 555, 561 (1992). Yet neither Leo 

nor Michael furnished evidence of any personal injury, let alone one traceable to the 

defendants. Even if we assume (as they ask us to) that injury can arise from rejected 

bids on tax-delinquent properties, it was Christopher alone—not Leo or Michael—who 

bid. Because Leo and Michael lack evidence of their own injury from a rejected bid, the 

district court properly ruled that they may not proceed on abstract claims that 

Wisconsin’s process for selling tax-delinquent properties is unlawful. 

 For the same reason, the district court properly denied Leo and Michael’s other 

requests. Their motions for a default judgment and to disqualify the defendants’ 

attorneys fail because, having no standing to sue, they had no right to such relief. Nor 

was the district court required to afford them an opportunity to amend their claims 

about Christopher’s injuries or to cure the defects in service on some parties. Any effort 

at amendment would be futile. Gandhi v. Sitara Capital Mgmt., LLC, 721 F.3d 865, 869 

(7th Cir. 2013). 

 Finally, Leo and Michael urge in their reply briefs that they stated personal 

claims against the Lake Como Sanitary District and the current owners of the properties 

adjoining Christopher’s land. They developed no arguments in their opening briefs 

regarding those claims, however, and thus waived these contentions. We could affirm 

the judgment on that basis alone. See Milligan v. Bd. of Tr. of S. Ill. Univ., 686 F.3d 378, 

386 (7th Cir. 2012); Wragg v. Vill. of Thornton, 604 F.3d 464, 467–68 (7th Cir. 2010). But 

even on the merits they lose. For one thing, unrelated claims against different 

defendants—as presented here—belong in separate lawsuits, FED. R. CIV. P. 20(a)(2); 

Owens v. Hinsley, 635 F.3d 950, 952 (7th Cir. 2011). Beyond this, Leo and Michael 

presented no evidence of wrongdoing by these defendants. Nor have they explained 

how the property owners—who lawfully bought their plots from the County—violated 

a duty owed to them. And, as the district court observed, they furnished no evidence of 

any sort of contract, implicit or otherwise, with Lake Como Sanitary District.

 Leo and Michael raised numerous other unavailing arguments on appeal. We 

have considered them, but they require no further discussion. We end by warning Leo 

and Michael that, as happened with Christopher, frivolous litigation will result in 

monetary sanctions that, if unpaid, can result in a Mack-based filing bar.
