SCOTUS keeps execution moratorium in place

As detailed in this SCOTUSblog post, the Justices continue to block every state effort to go forward with lethal injections.  Here's the basics:

The Supreme Court on Wednesday afternoon delayed the execution of Thomas D. Arthur, previously scheduled for 6 p.m. on Thursday. Arthur has a petition pending (Arthur v. Allen, 07-395) challenging the state’s use of a lethal injection protocol to carry out executions.... The Court in recent weeks has not permitted any execution to proceed when the inmate has sought a stay while challenging lethal injection. It is scheduled to hold a hearing on such challenges on Jan. 7 at 10 a.m.
