Two Oklahoma death row inmates (whose crimes both involved the brutal rape and murder of children) sued the government in order to find out the source of the drugs used in the lethal injection that they would receive. After the Oklahoma Court of Criminal Appeals gave the go-ahead for the executions, the state’s Supreme Court granted an indefinite appeal to the inmates. However, an Oklahoma House member drafted a resolution to impeach the justices who granted the stay, precipitating a 180 degree turnaround by the OK Supreme Court.
From The Guardian: The Oklahoma supreme court has dissolved its stay of the executions of two men who challenged the state’s secrecy about its source of lethal injection drugs. The court reversed the decision of a district court judge who said the law that keeps the source secret is unconstitutional.
