Last November, Argentine Judge María Alejandra Mauricio ruled that Cecilia isn't a thing - but is instead a being who is "subject to nonhuman rights." She follow that up by ordering that Cecilia be released from the zoo, and be allowed to live out her days at a chimpanzee sanctuary in Brazil.
Never before had a habeas corpus case for an ape resulted in such a move.
"We're not talking about the civil rights enshrined in the Civil Code," Mauricio told the journal Los Andes, clarifying her decision, "but instead the species' own rights: to development, to life in their natural habitat."
Cecilia's life was about to change - and this week, it did.
