The Supreme Court is poised to strike again on Wednesday when it hears arguments on whether to overturn the death sentence for a man who was sentenced to death by a jury for killing his ex-girlfriend.

The justices will be hearing arguments about whether to take up the case of Jeffrey Charles Williams, a former student at Florida Atlantic University who has been serving a life sentence in the death row of his former girlfriend.

The Supreme Court declined to hear the case last year, after a federal appeals court rejected Williams’ appeals of a lower court’s decision to reject his appeal of a lesser sentence.

Williams, then 22, was convicted in 1998 of first-degree murder and kidnapping for the murder of 26-year-old Tiffany Lynn Thompson.

Williams, a convicted murderer who has not been sentenced, was released from prison in 2015 after serving just over a year behind bars, but he remains on death row.

The Supreme Justice Department announced in May that Williams would be eligible for a reprieve from execution, though the government has yet to formally request clemency.

A number of states have also sought Williams’ release from death row, citing his history of mental health issues.

He has no criminal history and was a volunteer firefighter at a school that was closed because of a wildfire.
