SB 1604 Arizona Senate · 57th Legislature - First Regular Session

licensed secure facility; incompetent defendants

SB 1604 amends Arizona law to ensure time spent in a licensed secure health facility by defendants found incompetent to stand trial counts toward their criminal sentence for the original charges. It directly affects defendants in Arizona who are deemed incompetent and committed to such facilities under Section 13-4521. Key provisions require courts to credit all time served in these facilities against the sentence for the underlying offense (Section 13-712), limit commitment periods to the presumptive sentence for the original charge (Section 13-4521), and mandate specific hearings to determine dangerousness within 120 days (Section 13-4521). The bill streamlines how custody time is calculated for this population, ensuring it reduces the total prison time they would otherwise serve. This law was signed by the governor in May 2025.

Senate Engrossed Version Chaptered Version · 4 edits
MODERATE
The bill was finalized and approved by the Governor on May 2, 2025, transitioning from a Senate-drafted version to a Chaptered House version. The substantive scope of the law was significantly narrowed: the final text removed all amendments related to calculating prison terms and handling dangerous/incompetent defendants, leaving only a minor definition update for 'secure' facilities in the Arizona Revised Statutes.
Scope change
The bill's scope was reduced from amending three separate sections of the Arizona Revised Statutes (regarding prison time calculations, dangerous defendant proceedings, and facility definitions) to amending only one section (facility definitions).
SCOPE

All text regarding the calculation of imprisonment terms for defendants found competent to stand trial after involuntary commitment was removed.

The entire section governing trials for dangerous and incompetent defendants, including rules for evidence, commitment orders, and annual reporting, was removed.

DEFINITION

The definition of 'secure' facilities was retained and finalized, defining them as premises that limit a patient's exit in the least restrictive manner consistent with their treatment plan.

TECHNICAL

The document format was updated to reflect the House Engrossed Version and Chaptered status with Governor approval dated May 2, 2025.
