Since 2013, an organization called the Nonhuman Rights Project has brought before the New York State courts an unusual request - asking for habeas corpus hearings to determine whether Kiko and Tommy, two captive chimpanzees, should be considered legal persons with the fundamental right to bodily liberty.
While the courts have agreed that chimpanzees share emotional, behavioral, and cognitive similarities with humans, they have denied that they are persons on superficial and sometimes conflicting grounds. Consequently, Kiko and Tommy remain confined as legal "things" with no rights, and the major moral and legal questions remain unanswered: are chimpanzees mere 'things', as the law currently sees them, or can they be 'persons' possessing fundamental rights?
In Chimpanzee Rights: The Philosophers' Brief, a group of renowned philosophers consider these questions. Carefully and clearly, they examine the three lines of reasoning the courts have used to deny chimpanzee personhood: their species membership; whether they can bear rights and responsibilities; and whether they are members of a human community.
None of these, they argue, merits disqualifying chimpanzees from personhood. The authors conclude that when judges face the choice between seeing Kiko and Tommy as things and seeing them as persons - the only options under current law - Kiko and Tommy are persons who should, therefore, be protected from unlawful confinement "in keeping with the best philosophical standards of rational judgment and ethical standards of justice."
