Court hearing on whether chimps have rights

Lawyers for two chimpanzees are heading to court to argue that the animals have "personhood" rights and should be freed from the Long Island university where they are kept. The Nonhuman Rights Project has filed the petition in Manhattan on behalf of Leo and Hercules. The chimps are kept at Stony Brook University, where they are used in locomotion studies. Stony Brook is part of the state university system.
