He’s now got a human name � Matthew Hiasl Pan � but he’s having trouble getting his day in court.
Animal rights activists campaigning to get Pan, a 26-year-old chimpanzee, legally declared a person vowed Thursday to take their challenge to Austria’s Supreme Court after a lower court threw out their latest appeal.
A provincial judge in the city of Wiener Neustadt dismissed the case this week, ruling the Vienna-based Association Against Animal Factories has no legal standing to argue on the chimp’s behalf.
The legal tussle began in February, when the animal shelter where Pan and another chimp, Rosi, have lived for 25 years filed for bankruptcy protection.

Definitions! It’s not like, “it thinks so it’s a person.” It’s more like: people can think; what else thinks?

Freud could think. I say we try to legally reclassify the chimp as “Sigmund Freud.”
