304 P.3d 54
Utah2013Background
- Mateos-Martinez was convicted of aggravated murder and sentenced to life without parole.
- He was extradited from Mexico under an agreement not to seek the death penalty.
- Before trial, he moved to amend the first count from aggravated murder to murder; the motion was denied.
- At sentencing, victim impact testimony was admitted from Hernandez’s mother and sister without defense objection.
- The State merged one aggravated robbery count with aggravated murder; the jury trial included multiple felonies against Hernandez.
- The Utah Supreme Court affirmed the conviction and sentence, addressing charging discretion and victim impact evidence.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Charge choice violated uniform operation of laws | Mateos-Martinez alleged disparate treatment and over-prosecution. | State had legitimate charging discretion and no disparate treatment shown. | No uniform operation/equal protection violation. |
| Aggravated murder statute violates discretion limits | Statute gives unbridled prosecutorial discretion to seek aggravated murder. | Discretion is traditional prosecutorial discretion; Mohi distinguished. | Statute constitutional; discretion valid. |
| Admission of victim impact testimony at noncapital sentencing | Eighth Amendment prohibits certain victim impact evidence in sentencing. | Ott limits apply only to capital sentencing; noncapital context differs. | No Eighth Amendment bar in noncapital, adult sentencing; testimony admissible. |
