Kentucky ? Kentucky’s lethal injection method is constitutional, the state Supreme Court said in a ruling Wednesday that could clear the way for executions to resume.

Kentucky death row inmates Thomas Clyde Bowling, 52, and Ralph Baze, 49, challenged the state’s method of execution in 2004, saying the drug formula causes inmates to feel pain and is therefore cruel and unusual punishment.

The state has not declared a moratorium on executions but had not scheduled any since the lawsuit was filed. Bowling and Baze have received several stays of execution because of the court challenge.

“We have moved the process forward and, at the appropriate time, will seek a warrant for execution from the governor,” Kentucky Attorney General Greg Stumbo said in a news release Wednesday.
