The
Nonhuman Rights Project (
NhRP) is an American nonprofit animal rights organization seeking to change the legal status of at least some nonhuman animals from that of property to that of persons, with a goal of securing rights to bodily liberty and bodily integrity. The NhRP works largely through state-by-state litigation in what it determines to be the most appropriate common law jurisdictions and bases its arguments on existing scientific evidence concerning self-awareness and autonomy in nonhuman animals. Its sustained strategic litigation campaign has been developed primarily by a team of attorneys, legal experts, and volunteer law students who have conducted extensive research into relevant legal precedents. The NhRP filed its first lawsuits in December 2013 on behalf of four chimpanzees held in captivity in New York State. In late 2014, NhRP President Steven Wise and Executive Director Natalie Prosin announced in the
Global Journal of Animal Law that the Nonhuman Rights Project was expanding its work into other countries, beginning in Switzerland, Argentina, England, Spain, Portugal, and Australia.
