Arthur v. Dunn

(1) Whether, to satisfy his Glossip v. Gross burden, a condemned prisoner is limited to selecting an alternative method of execution from those already permitted by state statute; (2) whether Glossip requires a prisoner proposing an alternative lethal injection drug to provide a specific willing supplier for the alternative drug; (3) whether, to meet his Glossip burden, a condemned prisoner is required to provide, through a medical expert, a detailed protocol for an alternative method of execution including "precise procedures, amounts, times and frequencies of implementation"; and (4) whether it is a violation of the 14th Amendment guarantee of equal protection for a state to deviate arbitrarily from its voluntarily adopted execution safeguards.
