The Kentucky Supreme Court has ruled that the state's practice for determining if someone is intellectually disabled and not eligible to receive the death penalty is "unconstitutional."

News outlets report that the court on Thursday deemed Kentucky's use of an IQ test to determine if defendants have the mental competence to be sentenced to death outdated. Trial courts required defendants show an IQ of 70 or below before a hearing to determine intellectual disability.

The court's opinion came in the case of a man convicted of murdering a Muhlenberg County girl 20 years ago. Robert Keith Woodall was sentenced to death after pleading guilty in the killing of 16-year-old Sarah Hansen.

Woodall's attorneys, assistant public advocates Mike O'Hara and Dennis Burke, say the court's decision to abandon Kentucky's statute is modern and appropriate.
