This dubious and vexatious litigation makes a complete mockery of the whole concept of habeas corpus. Moreover, it has absolutely nothing to do with animal welfare and everything to do with the political ideology of animal-rights.
It is rather depressing that the media does not seem to know the difference between animal welfare and animal-rights. The most recent demonstration of this inability to tease these two issues apart appeared in the Green section of the Huffington Post website and relates to a story of an orangutan in Buenos Aires zoo lifted from the Reuters News Agency.
Acting on legal overtures by the Association of Officials and Lawyers for Animal Rights (AFADA) using a habeas corpus petition, on 21 December 2014 the Argentinean High Court appears to have ruled that this animal is deemed to be a 'nonhuman person'.
