The lawsuit between the Seidl family and the Wisconsin Interscholastic Athletic Association continues despite Tristen Seidl completing his senior football season at Arrowhead High School. Both sides agree the case is not moot. The WIAA has indicated it will meet with Arrowhead to discuss sanctions if the case is dismissed, with stripping the 2025 state championship among the possible penalties.
The case returns to court June 2, 2026.

Fire Destroys Home, Family Waits 17 Months for Repairs
A fire destroyed the Seidl family’s Dousman home in October 2023, when Tristen was a sophomore at Kettle Moraine High School. Contractors told them restoration was possible, so the family moved through four temporary residences over the next 17 months while keeping Tristen enrolled at Kettle Moraine. They expected to return home before his senior year.
By March 2025, contractors said the damage was too severe. The home came down in April. The family made their Lac La Belle rental permanent, signed a lease through June 2026, and enrolled Tristen at Arrowhead.
Both school districts approved the transfer. The WIAA blocked it.
WIAA Denies Transfer Waiver, Family Files Suit
WIAA officials ruled Tristen ineligible under transfer rules, saying the move was not required by a family relocation and did not qualify for an extenuating circumstances waiver. The family appealed to the WIAA Board of Control on August 15, 2025, but lost.
On August 19, Blayne and Jenell Seidl filed suit in Waukesha County Circuit Court, arguing the WIAA improperly asserted governmental authority over public school athletics. Family attorney William Rettko contended that nothing in state law gives the WIAA power to determine which students can participate in sports.
“We have no evidence in front of us that he can’t go back to Kettle Moraine, where he would have unrestricted eligibility,” WIAA attorney Brent Jacobson stated in court proceedings, according to The Freeman.
Tristen sat out the first two weeks of the season while hearings dragged on without a decision. On September 5, Judge Paul Bugenhagen Jr. granted a temporary injunction, finding Tristen would suffer irreparable harm if he missed his senior season and lost his scholarship offer from the University of Sioux Falls.
Seidl went on to play the final seven regular season games and all five postseason contests, finishing with 44 tackles, seven tackles for loss, and 4.5 sacks. He had four tackles, a sack, and a fumble recovery in the 18-15 state championship victory over Bay Port on November 21.
December Ruling: Motion to Dismiss Denied
In December, Judge Bugenhagen denied the WIAA’s motion to dismiss the certiorari claim and maintained the temporary order from September 5. He ordered both sides to submit additional briefs on whether the WIAA unlawfully exercises governmental authority.
WIAA attorneys had argued the organization is a private entity with contractual authority from its 513 member schools, not a governmental agency subject to court review. Jacobson pointed to Governor Tony Evers’ veto of a 2021 Assembly Bill that would have created exceptions for transfer cases. When vetoing the bill, Evers said he objected to the Legislature inserting itself into the decision-making process of a private, member-driven organization.
Both sides invoked the recently resolved Halter v. WIAA case involving former Waterford wrestler Hayden Halter. The Wisconsin Supreme Court found the WIAA acted reasonably in that dispute but stopped short of answering whether the organization qualifies as a state actor.
March 2026: Both Sides Agree Case Is Not Moot
The sides filed additional briefs in early 2026 on the question of state power, with both agreeing that the case is not moot just because Seidl was allowed to play. The question of whether Arrowhead could be stripped of its title and record in games Seidl participated in has taken center stage.
The WIAA could impose sanctions if the temporary injunction is reversed, the case is voluntarily dismissed, or courts determine it was unwarranted to allow Seidl to play.
“The reason the Seidl’s are going forward with this case is because the WIAA has indicated that if this case gets dismissed whether on a stipulation for dismissal or a court ruling, they intend to meet with Arrowhead to discuss sanctions for playing Tristen,” Rettko wrote in a brief, according to The Freeman. “One such sanction would be for the WIAA to strip Arrowhead of its 2025 State Football Championship.”
Rettko added that if the championship is stripped, “Tristen and the Seidl family may become targeted for public ridicule that may affect their safety, well-being and public standing.”
The WIAA has not taken action because its authority to do so “has not ripened,” Jacobson wrote. “Thus the Plaintiffs suggestion that the worst is coming is premature.”
However, Jacobson noted that Arrowhead “contractually agreed to risks involved in playing a student-athlete under a temporary injunction” and made “the voluntary choice to play him.”
Arrowhead Superintendent: District Is “Collateral Damage”
Arrowhead Union High School District is named as an involuntary plaintiff in the case but has not filed any motions or injunctions. Superintendent Conrad Farner said the district had no role in the Seidls’ decision to enroll, the WIAA’s ruling, or Judge Bugenhagen’s injunction.
“When the WIAA says a student athlete cannot participate in sports, we abide by that decision. When a judge rules that a student-athlete is eligible to participate, we abide by that decision,” Farner told The Freeman.
Farner said Seidl demonstrated the qualities Arrowhead teaches its athletes and deserved the opportunity to play.
“If Arrowhead is penalized by the WIAA, our entire football program, and really our entire school community, would be punished/sanctioned for following a judge’s order and for treating a student-athlete the same way we would treat any other student-athlete,” Farner said. “If Arrowhead is penalized by the WIAA, we are essentially collateral damage from circumstances and a lawsuit over which we had no involvement and no control.”

Broader Questions About WIAA Authority Remain
The Seidl lawsuit follows a string of legal challenges to WIAA transfer decisions. In February 2025, the Wisconsin Institute for Law and Liberty brought a similar constitutional challenge for Macy Weigel, a Baraboo student whose family faced financial hardship. That suit ended in May when the WIAA reversed its waiver decision.
The June hearing will tackle questions about athletic association authority that Wisconsin courts have avoided answering directly. If judges rule the WIAA lacks authority over public schools, the decision could reshape high school sports governance across the state.
Arrowhead’s state championship trophy remains in Hartland, but its fate depends on how courts rule in the coming months. The Seidl family continues fighting not just for their son’s legacy but to protect the school from sanctions imposed for following a court order.
