State of Arizona v. John Montenegro Cruz, 487 P.3d 991

Background:

In 2005 John Montenegro Cruz was convicted of first‑degree murder of a Tucson police officer and sentenced to death; Arizona Supreme Court affirmed in 2008 and U.S. Supreme Court denied certiorari in 2009.
Evidence included eyewitness/chase observations and ballistic matches tying Cruz’s revolver and cartridges to the five fatal shots.
Cruz filed earlier post‑conviction relief (PCR) and a federal habeas petition; after Lynch v. Arizona (Lynch II) (2016) he filed the PCR at issue claiming Simmons error.
Cruz argued Lynch II—holding that Simmons requires informing juries of parole ineligibility where future dangerousness is at issue—constituted a "significant change in the law" under Ariz. R. Crim. P. 32.1(g) and therefore justified collateral review.
The PCR court denied relief; the Arizona Supreme Court granted review to decide whether Lynch II was a significant change in the law, whether it applies retroactively, and whether it would probably overturn Cruz’s sentence.
The court held Lynch II was not a significant change in the law under Rule 32.1(g) because it was dictated by preexisting U.S. Supreme Court precedent (notably Simmons), and affirmed the denial of PCR.

Issues:

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Lynch II is a "significant change in the law" under Ariz. R. Crim. P. 32.1(g)	Lynch II did not change federal law; it merely applied longstanding Simmons precedent, so no Rule 32.1(g) relief	Lynch II was transformative because it corrected Arizona courts' misapplication and thus created a new, significant rule for Arizona cases	Lynch II is not a significant change in the law under Rule 32.1(g)
If significant, whether Lynch II applies retroactively and would probably overturn Cruz’s sentence	Argued relief unnecessary because Lynch II is not significant; alternatively, it should not change outcome	Lynch contended Lynch II should apply retroactively and likely would change the sentencing outcome	Court did not decide retroactivity or probability of overthrowing sentence because Lynch II fails the Rule 32.1(g) threshold
Whether a change in state courts’ application of federal precedent qualifies as a Rule 32.1(g) change	A change in application does not equal a change in the law for Rule 32.1(g) purposes	A shift in Arizona’s application (post‑Lynch I to Lynch II) is a transformative event warranting relief	Rule 32.1(g) requires an actual change in law, not merely a different state‑level application; Lynch II did not alter federal law
Whether Simmons was clearly established at time of Cruz’s trial and appeal	Simmons was established U.S. Supreme Court precedent before Cruz’s trial and direct appeal	Cruz argued Arizona courts’ prior interpretations made Simmons effectively unavailable	Court held Simmons was clearly established; Lynch II merely reaffirmed and applied that precedent
