In 1975, Belchertown was sued once again for denying its patients the right to vote (this was one of the first disability-related voting rights cases in the United States), and in 1977 a case was brought against the school on behalf of a 67-year-old severely retarded man with leukemia to determine if a court-appointed guardian ad litem could refuse treatment on his behalf.
