This article applies to habeas corpus proceedings in the superior court under Penal Code section 1473 et seq. or any other provision of law authorizing relief from unlawful confinement or unlawful conditions of confinement, except for death penalty-related habeas corpus proceedings, which are governed by rule 4.560 et seq.
Plain-English Summary (for reference only — not a substitute for the rule text above)
A habeas corpus case is a court proceeding where someone who is locked up argues that their imprisonment or the conditions of their confinement are unlawful. This rule applies to those types of cases when they are filed in the superior court.
This particular rule does not cover cases where someone on death row files a habeas corpus petition. Those cases follow a different set of rules, starting with Rule 4.560.
