Animal rights groups are trying to block a permit allowing Yerkes National Primate Research Center to move eight of its chimpanzees abroad.
The coalition led by the New England Anti-Vivisection Society, or NEAVS, filed a lawsuit Monday asking a federal judge to overturn the U.S. Fish and Wildlife Service’s decision to grant the permit.
Yerkes, which is part of Atlanta's Emory University, wants to donate the chimpanzees to Wingham Wildlife Park in England. The transfer is considered an export and requires a permit under the Endangered Species Act.
