Meanwhile in Argentina:
Captive orangutan Sandra has human right to freedom, Argentine court rulesAn orangutan held in an Argentine zoo can be freed and transferred to a sanctuary after a court recognised the ape as a "non-human person" unlawfully deprived of its freedom, lawyers say.
Animal rights campaigners filed a habeas corpus petition - a document more typically used to challenge the legality of a person's detention or imprisonment - in November on behalf of Sandra, a 29-year-old Sumatran orangutan at the Buenos Aires zoo, arguing she was "suffering an unwarranted confinement".
