The U.S. Supreme Court declined to overturn a Texas court ruling that allowed hypnosis testimony in the case of Alfredo Roen Serna, a death row inmate in Texas.

The appeal challenged the admissibility of investigative hypnosis performed by law enforcement, which was used in Serna's trial. The decision upholds the Texas court's stance on hypnosis evidence, leaving open questions about the reliability and fairness of such testimony in criminal cases.

This ruling affects legal standards in Texas and potentially other jurisdictions regarding hypnosis in investigations.
