Ironic since in the U.S. we seem to have a problem granting them to the humans!  Seriously though, it's a neat bill - it would make it illegal to kill an Ape (except in self-defense).  It would also protect them from torture which would preclude their subjugation for medical experimentation.  And the best part - no arbitrary imprisonment! 

Actually, while circuses and zoos would be prevented from imprisoning any further Apes, those currently housed will remain (for their own protection) but it would require the administrations to provide more humane housing.    And speaking as someone who has been to the Barcelona Zoo, I can tell you it is a place where the animals are in sore need of some pampering.
