The report, published by Al Jazeera, gave no further details about the inmate, the state involved or the circumstances of the failed injection attempts.
Cases in which executions have been halted or have failed have previously raised legal questions about whether a second attempt at lethal injection amounts to cruel and unusual punishment. A demand for release would go further than a request to halt an execution, asking a court to end the case entirely. The legal arguments in such cases typically centre on the Eighth Amendment to the United States Constitution, which prohibits cruel and unusual punishment. The outcome of this demand was not known at the time of writing.
