A Chimpanzee Wins Habeas Corpus

In Mendoza, Argentina, a judge looked at a chimpanzee alone in a concrete cage and ruled that the law meant to free wrongly held humans applied to her too.

The facts

Date of ruling
November 3, 2016
Court
Third Court of Guarantees, Mendoza, Argentina, Judge María Alejandra Mauricio
Petitioner
AFADA, the Association of Officials and Lawyers for Animal Rights
Outcome
Zoo ordered to transfer Cecilia within six months; she arrived at the Great Ape Project sanctuary in Sorocaba, Brazil, in April 2017

Cecilia had spent years in a bare enclosure at the Mendoza Zoo, and by 2016 she was alone there; the companions she had lived alongside were gone. The Association of Officials and Lawyers for Animal Rights, known by its Spanish acronym AFADA, filed a writ of habeas corpus on her behalf before the Third Court of Guarantees in Mendoza, a legal tool built for people held unlawfully. On November 3, 2016, Judge María Alejandra Mauricio granted it, ruling that great apes are sentient beings and non-human persons subject to rights rather than property the zoo could simply keep. She gave the zoo six months to arrange Cecilia's transfer to a sanctuary in Brazil. No animal anywhere had been freed by habeas corpus before.

Why it still matters

It was the first time a court anywhere used habeas corpus, a protection built for illegally detained humans, to order a nonhuman animal set free. The ruling didn't rewrite the law for every caged animal, but it gave lawyers a real precedent to point to, and it gave one chimpanzee the rest of her life among others of her kind instead of alone.
