Whether Whitmore had Article III standing in his individual capacity to challenge Arkansas's execution of Simmons without mandatory appellate review.
Holding
No. Whitmore alleged neither a concrete, imminent personal injury nor anything more than a generalized interest in lawful government.
Reasoning
Article III permits federal courts to decide only actual “cases” and “controversies.” A plaintiff must show a concrete and particularized injury that is actual or imminent, fairly traceable to the challenged conduct, and likely to be redressed by a favorable ruling. The Court emphasized that these jurisdictional requirements apply before, and independently of, any assessment of whether the challenged execution would violate the Eighth Amendment.
Whitmore argued that excluding Simmons' case from Arkansas's capital-case comparison database could harm Whitmore if he later obtained federal habeas relief, was retried, again convicted, again sentenced to death, and then received a new proportionality review. That chain of events was far too speculative. Whitmore's current conviction and sentence were final, and even a successful habeas petition would not establish that he would be retried, resentenced to death, or benefit from comparison with Simmons' materially different crimes.
Whitmore also asserted an interest, as an Arkansas citizen, in ensuring that the State complied with the Eighth Amendment. But an asserted right to have the government obey the Constitution is a generalized grievance shared by all citizens, not the distinct and palpable injury that Article III requires.
The Court rejected Whitmore's request for relaxed standing rules because death is uniquely serious. Article III's case-or-controversy requirement is a constitutional limit on judicial power, not a discretionary rule of practice that the Court may relax because the underlying claim is important.
