The Humane Society of the United States, the Humane Society Legislative Fund, Animal Protection of New Mexico, Holly Andreas, Elizabeth Reed, and Nancy Megna have filed suit against the National Institutes of Health. Their complaint alleges that the agency’s decision to keep the chimpanzees at the Alamogordo Primate Facility instead of retiring them to the federal sanctuary system violates the Chimpanzee Health Improvement, Maintenance, and Protection Act and the Administrative Procedure Act.
