A few days ago the Colorado Supreme Court ruled unanimously that elephants do not have legal standing to challenge their captivity. This ruling, which followed a lawsuit filed by the Nonhuman Rights Project (NRP), an organization advocating for legal personhood and rights for animals (based on the legal procedure Habeas Corpus), beyond blocking the legal effort to release five African elephants from the prison in Cheyenne Mountain Zoo in Colorado Springs and move them to an elephant sanctuary, along with previous lawsuits by the NRP that were also rejected by courts in New York, California, and Hawaii, formally and legally indicates and perpetuates speciesism.
