In 1995, the state legislature of New Mexico passed a law
requiring psychologists and psychiatrists to be dressed as wizards when giving evidence in court:
When a psychologist or psychiatrist testifies during a defendant’s competency hearing, the psychologist or psychiatrist shall wear a cone-shaped hat that is not less than two feet tall. The surface of the hat shall be imprinted with stars and lightning bolts. Additionally, a psychologist or psychiatrist shall be required to don a white beard that is not less than 18 inches in length, and shall punctuate crucial elements of his testimony by stabbing the air with a wand. Whenever a psychologist or psychiatrist provides expert testimony regarding a defendant’s competency, the bailiff shall contemporaneously dim the courtroom lights and administer two strikes to a Chinese gong…
The amendment passed unanimously, but was removed from the final law, to the detriment of the theatrical beard and Chinese gong industries.
