The Colorado high court ruled in favor of Cheyenne Mountain Zoo after an animal rights group alleged the park's elephants were 'unlawfully confined.'

The group argued that elephants at Colorado Zoo showed signs of brain damage as the place was essentially a "prison" for such intelligent creatures.

Five elephants at a Colorado zoo may be “majestic” but, since they’re not human, they do not have the legal right to pursue their release, Colorado’s highest court said Tuesday.

Outrage erupted among animal welfare activists after Colorado courts ruled that five captive elephants could not petition for release. An animal rights group presented the case in Colorado. Still, the state’s supreme court could not allow an elephant to file a habeas corpus claim because elephants are not considered human.

A lawsuit arguing elephants should be freed from a zoo has failed in court, with the judge ruling that "majestic" mammals do not have the same rights as humans.

History will look upon this ruling as a grave injustice,” animal law professor and director of the Animal Activist Legal Defense Project Justin Marceau said.

The high court rejected arguments that elephants qualify as “persons” under state law and suggested animal advocates turn to the legislative branch to expand legal rights.
