TALLAHASSEE — The Florida Supreme Court is refusing to block the state's first execution after a hiatus of more than 18 months.

The court on Monday ruled 6-1 that the state can go ahead with the scheduled Aug. 24 execution of Mark Asay.

Asay, 53, was originally scheduled to be executed in March 2016, for the 1987 murders of Robert Lee Booker and Robert McDowell in Jacksonville.

The execution was put on hold after the U.S. Supreme Court found the state's death penalty sentencing law unconstitutional.

The Legislature has since twice changed the law, most recently this year when it required a unanimous jury recommendation for the death penalty.

Justices rejected several arguments that Asay made to block his execution, including his questioning of a new drug the state plans to use for lethal injection.
