After a 13-year hiatus, South Carolina is looking to resume three execution methods: lethal injection, firing squad, and the electric chair. The decision is pending Tuesday’s oral arguments for four death row inmates’ lawsuits, which claim the methods are cruel and unusual punishments.

The inmates’ lawyers also plan to argue Tuesday that the state’s 2023 law permitting lethal injection to resume isn’t transparent enough. The shield law was passed to protect the identities of companies selling drugs used for lethal injection or any prison employees involved in the execution procedure.
