Summary: The Petitioners, including the Nonhuman Rights Project, Inc . filed two petitions for habeas corpus relief on behalf of Tommy and Kiko, two adult male chimpanzees. The petitions stated that chimpanzees are intelligent, have the ability to be trained by humans to be obedient to rules, and to fulfill certain duties and responsibilities. Therefore, chimpanzees should be afforded some of the same fundamental rights as humans which include entitlement to habeas relief. The Respondents, included Tommy’s owners, Circle L Trailer Sales, Inc. and its officers, as well as Kiko’s owners, the Primate Sanctuary, Inc. and its officers and directors. The Supreme Court, New York County, declined to extend habeas corpus relief to the chimpanzees. The Petitioners appealed. The Supreme Court, Appellate Division affirmed and held that:(1) the petitions were successive habeas proceedings which were not warranted or supported by any changed circumstances; (2) human-like characteristics of chimpanzees did not render them “persons” for purposes of habeas corpus relief; and (3) even if habeas relief was potentially available to chimpanzees, writ of habeas corpus did not lie on behalf of two chimpanzees at issue.
