Leilani Marietta (O'Malley) Muir (July 15, 1944 – March 14, 2016), previously named Leilani Marie Scorah, was the first person to file a successful lawsuit against the Alberta government for wrongful sterilization under the Sexual Sterilization Act of Alberta. Her case led to the initiation of several other class action lawsuits against the province for wrongful sterilization. Muir's advocacy shed light on eugenics, institutionalisation, human rights for persons with a disability, and self-advocacy.
