In the "Monks" case ("Estate of Monks", 4. Civ. 2835, Records of California Court of Appeals, Fourth district), the Superior Court of San Diego County in 1939 decided to invalidate the marriage of Marie Antoinette and Allan Monks because she was deemed to have "one eighth negro blood". The court case involved a legal challenge over the conflicting wills that had been left by the late Allan Monks; an old one in favor of a friend named Ida Lee, and a newer one in favor of his wife. Lee's lawyers charged that the marriage of the Monkses, which had taken place in Arizona, was invalid under Arizona state law because Marie Antoinette was "a Negro" and Alan had been white. Despite conflicting testimony by various expert witnesses, the judge defined Mrs. Monks' race by relying on the anatomical "expertise" of a surgeon. The judge ignored the arguments of an anthropologist and a biologist that it was impossible to tell a person's race from physical characteristics.
