sciencehabit writes: In a decision that effectively recognizes chimpanzees as legal persons for the first time, a New York judge [Monday] granted a pair of Stony Brook University lab animals the right to have their day in court. The ruling marks the first time in U.S. history that an animal has been covered by a writ of habeus corpus, which typically allows human prisoners to challenge their detention. The judicial action could force the university, which is believed to be holding the chimps, to release the primates, and could sway additional judges to do the same with other research animals. Update: 04/21 21:39 GMT by S : Science has updated their article with news that the court has released an amended order (PDF) with the words "writ of habeas corpus" removed, no longer implying that chimps have legal personhood. The order still allows the litigation to go forward, but we'll have to wait for resolution.
