Quick Summary of Xylon

The Xylon, an ancient Greek punishment device resembling stocks, was employed to penalize individuals who committed crimes. The XYY-Chromosome Defense is a legal strategy utilised by certain male defendants who argue that their criminal actions are a result of possessing an additional Y chromosome, leading to uncontrollable aggressive tendencies. Nevertheless, the majority of courts have dismissed this defence due to insufficient scientific proof backing its claims.

Full Definition Of Xylon

Xylon (zI-lon), n. [from Greek xulon “wood”], refers to an outdated punishment device similar to stocks. The XYY-chromosome defence is a criminal law defence that is often used as the basis for an insanity plea. In this defence, a male defendant argues that his criminal behaviour is a result of the genetic abnormality of having an extra Y chromosome, which leads to uncontrollable aggressive impulses. For instance, a man who commits a violent crime may claim that his additional Y chromosome caused him to act impulsively and without control. However, most courts have rejected this defence due to the uncertain scientific basis. According to one commentator, an attorney defending an individual with XYY chromosomes would need to call upon both a geneticist and a psychiatrist to provide expert testimony. The geneticist would testify about the individual’s genetic structure, any relevant distinguishing characteristics for an insanity defence, and the findings of family studies that determine the influence of genetics and environment on the individual’s development. The psychiatrist’s testimony would focus on the defendant’s mental capacity or condition. Nevertheless, since there is insufficient medical support for the XYY defence, courts are understandably unsympathetic to defence efforts to obtain such expert testimony.
