An appeals court in Manhattan on Thursday rejected a constitutional challenge to the Health Care Decisions Act for Persons with Mental Retardation, which was passed in 2002 to give guardians the right to refuse life-saving treatment for retarded individuals under their care.

A unanimous panel of the Appellate Division, 1st Department, found that the petitioner, Chantel R., a 26-year-old mentally retarded woman, could not show a violation of the Equal Protection Clause or her due process rights.
