A federal lawsuit alleges that a McHenry County agency catering to special-needs residents discriminated against at least two of them by refusing to administer an anti-seizure medication if needed.

The lawsuit filed Monday by the U.S. Attorney’s Office alleges that the decision by the Northern Illinois Special Recreation Association restricted two girls’ access to its programs and therefore violated the Americans with Disabilities Act.

The U.S. Attorney’s Office is asking the court to require NISRA to administer the anti-seizure medication Diastat to clients who may need it.
