MAY, Judge.

Daniel Claybon appeals the dismissal of his fifth postconviction-relief (PCR) 

application. We affirm.

In 1990, Claybon was convicted of first-degree murder and sentenced to life 

in prison without parole. He was eighteen years old at the time of the crime. His 

conviction was affirmed by this court. See State v. Claybon, No. 90-1605, 1992 

WL 198231, at *1 (Iowa Ct. App. Feb. 25, 1992). 

In the years that followed, Claybon filed four PCR applications. All four

applications were denied. And each denial was affirmed by an appellate court. 

See Claybon v. State, No. 15-0817, 2014 WL 3282228, at *2 (Iowa Ct. App. June 

15, 2016) (affirming the dismissal of Claybon’s fourth PCR application); Claybon 

v. State, No. 12-1396, 2014 WL 999057, at *1–2 (Iowa Ct. App. May 14, 2014) 

(detailing Claybon’s first three PCR applications and the procedural history for 

each). 

In June 2017, Claybon filed the present PCR application. This time, he 

claimed State v. Lyle, 854 N.W.2d 378 (Iowa 2014), made his sentence 

unconstitutional. The State moved to dismiss because the application was timebarred. Claybon resisted the motion and, moreover, filed a motion requesting 

appointment of an expert at the State’s expense. The State then filed an amended 

motion to dismiss arguing Lyle did not provide a ground on which Claybon could 

be granted relief. Following a hearing, the PCR court granted the State’s motions 

and dismissed Claybon’s application. Claybon appeals. “Our review in [PCR] 

proceedings is for correction of errors at law.” Manning v. State, 654 N.W.2d 555, 

558–59 (Iowa 2002).

In their briefs, Claybon and the State address a number of procedural 

issues. But we need not resolve most of them. Ultimately, Claybon cannot obtain 

relief unless Lyle—which required special sentencing procedures for juvenile

offenders faced with minimum prison sentences—also extends to offenders like 

Claybon, who were adults when they committed murder. But Lyle does not apply 

to Claybon. The Lyle court made it clear that its holding “has no application to 

sentencing laws affecting adult offenders.” 854 N.W.2d at 403; accord Smith v. 

State, No. 16-1711, 2017 WL 3283311, at *2 (Iowa Ct. App. Aug. 2, 2017) (quoting 

Lyle, 854 N.W.2d at 403).

Even so, Claybon argues, the PCR court should have appointed an expert

“to present testimony on the most recent studies regarding the development of the 

human brain.” But Claybon has not shown that expert testimony would make a 

difference in this case. Claybon has not cited, and we have not found, Iowa cases 

suggesting that—given the right scientific record—the Lyle protections would be 

extended to adult offenders. Nor do the texts of our constitutions, as originally 

understood, suggest the Lyle procedures are required. See Goodwin v. Iowa Dist. 

Ct. for Davis Cty., 936 N.W.2d 634, 649 (Iowa 2019) (McDonald, J., specially 

concurring).

Claybon is not entitled to relief. The PCR court was correct in dismissing 

his application.

AFFIRMED.
