A federal judge has tossed claims brought by the parents of a child with hearing and visual impairments who sued a school district for denying their son access to schooling for two years and for allegedly discriminating against them by association.

U.S. District Judge Gerald J. Pappert of the Eastern District of Pennsylvania granted the School District of Philadelphia’s motion to dismiss claims of discrimination by association under the Americans with Disabilities Act, the Rehabilitation Act and the Pennsylvania Human Rights Act brought by plaintiffs Troy Souders and Melissa McCullough.
