An Oregon horse is suing his former owner for damages relating to health issues connected to alleged neglect. If successful, the case will be the first to establish that animals have the legal right to sue their alleged abusers in court.

Last year, an 8-year-old Quarter Horse, now called Justice, was surrendered to a rescue by his owner. At the time of the surrender, he was allegedly emaciated, infested with lice, suffering from rain rot, and had swollen genitalia due to frost bite. Gwendolyn Vercher, the horse’s owner at the time of the surrender, later pleaded guilty to animal cruelty.

In May, the Animal Legal Defense Fund (ALDF) filed a personal injury complaint in the Washington County, Oregon, Circuit Court against Vercher on the animal’s behalf.
