Chimpanzees do not deserve the same rights as people, a New York state appeals court unanimously concluded on Thursday, as it refused to order the release of two of the animals to a primate sanctuary.

The 5-0 decision by the Appellate Division in Manhattan is the latest defeat for the Nonhuman Rights Project and its lawyer Steven Wise in a long debate over whether caged chimpanzees are actually legal persons entitled like humans to bodily liberty.

Tommy and Kiko, the chimpanzees in question, are held by private owners in upstate New York.
