A split decision that sided with a group of 10 death row inmates that argued state legislature could only set the execution policy.  Death row inmate Jack Harold Jones filed a lawsuit in 2010 against the head of Arkansas Department of Correction.  With the help of nine other inmates, they argued that a 2009 law that gave the department and its director to choose the chemical mixture administered in executing inmates violated the state’s separation of powers between the legislative and executive branches.
