Significant Cases

  • A.H. v. Illinois High School Association 263 F. Supp. 3d 705 (N.D. Ill. 2017), 881 F.3d 587 (7th Cir. 2018) – A.H., a T-36 disabled student athlete, filed suit against the IHSA contending that he was discriminated against under the ADA and Equal Protection Clause of the U.S. Constitution on the basis that the IHSA did not create a separate division in the State Series with different qualifying standards for para-ambulatory runners, such as A.H. At the District Court level, the court granted summary judgment in favor of the IHSA finding that A.H.’s request went beyond the scope of “reasonable accommodations” as required by the ADA. A.H. appealed to the Seventh Circuit Court of Appeals, and it affirmed. The Seventh Circuit Court of Appeals found that requiring the IHSA to lower its qualifying time standards would operate as a fundamental alteration of the State Track & Field competition. Furthermore, the Seventh Circuit Court of Appeals held that the IHSA provided an opportunity for A.H. to participate and compete on his high school team. The IHSA was not required under the ADA to guarantee A.H. certain results. This was the first appellate decision in the country which examined the extent to which accommodations are required in high school sports for student athletes with disabilities. 
  • Administrators of the Estate v. Defendant Obstetricians and Clinic – Successfully defended a medical malpractice case that was brought against two defendant obstetricians and a medical clinic. The plaintiffs alleged that one defendant obstetrician failed to properly diagnose intrauterine growth restriction (“IUGR”) in one twin fetus and implement additional antenatal testing, while the other obstetrician failed to perform a growth ultrasound and a C-section immediately upon the mother’s presentation to labor and delivery with premature rupture of membranes. Plaintiffs contended that these deviations resulted in one of the twins being stillborn. At the end of a 10-day jury trial, obtained a directed verdict in favor of the obstetrician and obtained a jury verdict in favor of the medical clinic for the actions of the second obstetrician.

  • Illinois High School Association v. Illinois Attorney General US District Court Northern District Illinois, Case Nos: 12 MR 151, 12 CV 1155, 12 CV 3758 – Successfully resolved litigation on behalf of the IHSA involving the rights of student athletes with disabilities in high school athletics.  In a case of first impression, the Illinois Attorney General argued that student athletes with disabilities needed separate events and modified qualifying times to earn points for their team and have an equal opportunity to participate in high school athletics. The case was successfully resolved on behalf of the IHSA after 2.5 years of intense litigation, which focused upon the application and scope of Titles 2 and 3 of the Americans with Disabilities Act and Section 504 of the Rehabilitation Act of 1973.
