Background
Hilton Allen Michael Acker was charged with two counts of sexual assault, second degree kidnapping, aggravated robbery, and a crime-of-violence sentence enhancer. The arrest-warrant affidavit alleged that Acker entered the victim’s car, forced her at gunpoint to drive to an alley and then a parking garage, sexually assaulted her at both locations, and took her phone.
Under a plea agreement, Acker pleaded guilty to second degree kidnapping and the crime-of-violence enhancer. The agreement set a mandatory minimum of sixteen years and capped his prison sentence at thirty years. At sentencing, the prosecution sought thirty years, while the defense sought sixteen. Acker, his sister, and his cousin asked for leniency and described his positive family role and rehabilitation potential.
The Court’s Holding
The Colorado Court of Appeals affirmed Acker’s thirty-year sentence. Because the sentence did not exceed the plea agreement’s stipulated cap, Acker could not appeal the sentence’s intrinsic fairness or appropriateness. He could challenge only the manner in which the district court imposed it, including whether it relied on improper information or procedures.
The court concluded that the district court did consider the mitigation evidence. The sentencing judge expressly credited the family members’ descriptions of Acker’s character and potential for rehabilitation, but found those considerations outweighed by the offense’s severity, Acker’s criminal history, and the danger he posed to the community. The appeals court also rejected Acker’s claim that the court improperly relied on parole eligibility: the sentencing judge mentioned parole only while explaining that the plea cap was already lenient compared with the potentially consecutive sentences Acker could have faced after trial.
Key Takeaways
- A defendant who receives a sentence within a plea agreement’s stipulated range generally cannot appeal the sentence’s propriety.
- A sentencing court may give greater weight to aggravating circumstances than mitigation after considering both.
- Discussing parole eligibility does not establish improper sentencing reliance when the record shows the court used it to compare the plea disposition with possible trial exposure.
Why It Matters
The decision distinguishes between an unreviewable challenge to the weight a sentencing court assigned competing factors and a reviewable claim that the court ignored mitigation or used an improper sentencing procedure. A defendant challenging a sentence within an agreed-upon cap must identify a flaw in the sentencing process, not merely disagree with the sentencing court’s balancing.
