A private school for disadvantaged youth reversed a policy barring students with HIV, handing a victory to the AIDS Law Project of Pennsylvania and Class of 2012 alumnus Matthew Mossman.

The Milton Hershey School, which is at the center of a discrimination suit the AIDS Law Project filed in 2011, announced it will allow HIV positive students to enroll.

The announcement marks “a great victory,” said Ronda B. Goldfein, executive director of the AIDS Law Project, which is representing a 14-year-old boy who was prohibited from enrolling exclusively because of his HIV status.

Mossman, who began working on the lawsuit through the law school’s Civil Litigation Field Clinic, is continuing to help with the case on a pro bono basis.

“The client is still seeking all remedies at law available to him,” said Mossman, who will soon begin pursuing a master’s degree in politics at The New School in New York City.
