An anonymous reader writes "A Brazilian court has already issued a writ of habeas corpus in the name of a chimp. And now an Austrian court may well decide that a chimpanzee is a 'person' with what up until now have been called human rights."
From the story in the Guardian/Observer: "He recognizes himself in the mirror, plays hide-and-seek and breaks into fits of giggles when tickled. He is also our closest evolutionary cousin. A group of world leading primatologists argue that this is proof enough that Hiasl, a 26-year-old chimpanzee, deserves to be treated like a human. In a test case in Austria, campaigners are seeking to ditch the 'species barrier' and have taken Hiasl's case to court. If Hiasl is granted human status — and the rights that go with it — it will signal a victory for other primate species and unleash a wave of similar cases."
