Washington – Please find a statement from PETA President Ingrid Newkirk on the death of Sandra Day O’Connor:

PETA will be forever grateful to former Justice Sandra Day O’Connor for ruling in our favor in the landmark Silver Spring monkeys case, the first one involving animals used in laboratories that came before the U.S. Supreme Court. The investigation of the government-funded laboratory resulted in the first-ever criminal conviction of a U.S. experimenter on cruelty-to-animals charges and catapulted PETA’s animal rights mission into the mainstream. Justice O’Connor was a heralded, accomplished American trailblazer, but we’ll always remember her for her kindness and defense of the 17 abused monkeys she helped with her vote.

PETA—whose motto reads, in part, that “animals are not ours to experiment on”—opposes speciesism, a human-supremacist worldview. For more information, please visit, listen to The PETA Podcast, or follow the group on X (formerly Twitter), Facebook, or Instagram.
