Federal Appellate Experience

  • Won appeal in the Seventh Circuit Court of Appeals in Stockbridge Munsee Community v. Ho-Chunk Nation, 922 F.3d 818 (2019), a case brought by one American Indian tribe against another over the latter's right to conduct gaming under the Indian Gaming Regulatory Act. Affirming the district court's ruling in favor of the Ho-Chunk Nation, the Court held that the plaintiff-tribe's claim was both outside the statutory zone of interests and barred by the statute of limitations.
  • Authored an amicus brief in the U.S. Supreme Court in Bostock v. Clayton County, 140 S. Ct. 1731 (2020), which held that Title VII of the Civil Rights Act of 1964 prohibits employment discrimination based on sexual orientation and transgender status. The brief was filed in support of the prevailing employees and stressed many of the textual, logical, and institutional arguments the Court ultimately found persuasive.
  • Authored an amicus brief in the U.S. Supreme Court in Gill v. Whitford, 138 S. Ct. 1916 (2018), a legislative redistricting case involving claims of partisan gerrymandering.
  • Briefed and orally argued an appeal in the Seventh Circuit Court of Appeals regarding qualified immunity.

Wisconsin Appellate Experience

  • Achieved victory in the Wisconsin Supreme Court for a real estate developer in CityDeck Landing v. Circuit Court, 2019 WI 15, a case announcing important limits on a trial court's authority to interfere with private arbitration proceedings.
  • Obtained 4-1 win in the Wisconsin Supreme Court in Enbridge Energy Co. v. Dane County, 2019 WI 78, which ruled that a local government exceeded the scope of its land-use authority when it imposed unlawful conditions on an energy pipeline company's zoning permit. The Court also held that it has discretion to modify portions of a challenged zoning permit, without remanding the permit to the local government for further consideration.
  • Authored an amicus brief in Michels v. Lyons, 2019 WI 57, a Wisconsin Supreme Court case involving questions of constitutional interpretation and the protection of individual liberty interests under the Fourteenth Amendment.
  • Authored multiple successful petitions for review to the Wisconsin Supreme Court.
  • Convinced the Wisconsin Court of Appeals to dismiss an appeal for lack of jurisdiction before proceeding to briefing on the merits, thereby saving substantial time and resources for the client.
  • Represented a national outdoor advertising company before the Wisconsin Supreme Court in an appeal about regulatory takings and nonconforming uses.

Administrative Appeal & Trial Experience

  • Obtained a favorable judgment before the U.S. Court of International Trade in CSC Sugar LLC v. United States, 317 F. Supp. 3d 1334 (2019), a case challenging the Department of Commerce's actions in approving countervailing and antidumping duty trade agreements detrimental to our client's interests. In a first-of-its kind ruling, the court vacated the agreements.
  • Won summary judgment for a real estate developer pursuing a claim for fraudulent transfer, enabling the developer to collect a substantial prior judgment.
  • Won summary judgment and attorneys' fees for a professional organization in a copyright infringement suit that hinged on whether the organization's volunteers were agents under the "work made for hire" doctrine.
Case Studies
CityDeck Landing LLC

What began as a private arbitration regarding a dispute over the construction of an apartment building in Green Bay turned into a case with much larger implications when a subcontractor’s insurer filed a separate action in Wisconsin state circuit court seeking a declaration regarding its coverage obligations, as well as a stay of the arbitration until the coverage issues were resolved.


When the U.S. Commerce Department amended a prior suspension agreement regarding the importation of Mexican sugar in 2017, it changed the purity definition of refined sugar, effectively altering the product definition for trade purposes and significantly imperiling the business of CSC Sugar, whose cutting-edge refining processes were developed to use a higher purity input. CSC came to Husch Blackwell’s international trade team to help craft a strategy to deal with this unexpected hazard.
