US Supreme Court allows execution of Christa Pike to go ahead

The US Supreme Court has cleared the way for death row inmate Christa Pike to become the first woman executed in Tennessee in more than 200 years.

The justices overturned a last-minute reprieve that was granted by an appeals court on Wednesday morning about an hour before Pike, 50, was due to be put to death.

Tennessee's attorney general had asked the Supreme Court to overrule the lower court. Pike was sentenced to death in 1996 for the murder of Colleen Slemmer.

She was 18 when she and her then-boyfriend, Tadaryl Shipp, beat, tortured and killed the 19-year-old, whom they met at a job training camp for troubled teens.

Supreme Court Justice Brett Kavanaugh, a conservative, granted Wednesday evening's application to vacate the stay of the execution. No explanation was provided in the order.

The top court's three liberal justices - Sonia Sotomayor, Elena Kagan and Ketanji Brown Jackson - dissented.

Sotomayor wrote that the decision cleared the way for Tennessee to execute Pike before her pending legal challenges to her conviction "can be properly considered".

"Tennessee's desire to expedite Pike's execution by a few days or even weeks cannot outweigh her 'fundamental interest in [her] own life," she said.

The latest Supreme Court ruling landed just before 18:00 local time. The state's execution order is due to expire at midnight.

If time runs out, the Tennessee Supreme Court would need to set a new execution date, the Associated Press news agency reports.

In a ruling earlier on Wednesday, judges from the US Court of Appeals for the Sixth Circuit paused the execution saying they needed more time to consider the arguments in Pike's case.

Pike's lawyers said that for years, the state of Tennessee had argued in court that she lied about being sexually abused as a child.

But at a recent hearing about her execution method, the state said it did not dispute that she had suffered sexual abuse and rape.

Pike's legal team asked the appeals court to send her motion back to the district court, arguing that if the federal courts had based their ruling on the state's earlier claim that she was lying, then the federal review was affected.

It was the second time in as many days that the US Supreme Court gave the go-ahead for the convicted murderer's death by lethal injection. On Tuesday, the justices rejected a different appeal from Pike.

Tennessee's governor also denied a clemency request this week from the death row inmate.
