Background
A jury convicted Ralph H. Jackson of nine felonies, and the district court adjudicated him a habitual criminal and sentenced him to 120 years to life. His conviction became final in March 2013. After filing multiple postconviction motions and appeals between 2013 and 2021, Jackson filed another motion in May 2025 challenging his habitual-criminal sentence.
Jackson relied on Erlinger v. United States, a 2024 U.S. Supreme Court decision recognizing a constitutional right to have a jury determine whether prior convictions occurred on different occasions under the federal Armed Career Criminal Act. Although Jackson captioned his filing as a motion to correct an illegal sentence under Colorado Rule of Criminal Procedure 35(a), he argued that his sentence was unconstitutional because a judge, rather than a jury, made the habitual-criminal findings.
The district court requested a prosecution response but did not send the motion to the public defender despite Jackson’s request for counsel, and it prohibited Jackson from replying. It then denied the motion and the request for counsel based on the prosecution’s argument that Erlinger did not apply retroactively.
The Court’s Holding
The Colorado Court of Appeals affirmed. It treated Jackson’s motion according to its substance as a constitutional challenge under Rule 35(c), not an illegal-sentence claim under Rule 35(a). Because Jackson filed the motion more than twelve years after his conviction became final, the claim was untimely. If Erlinger merely extended the rule announced in Apprendi v. New Jersey, the claim was also successive because Jackson could have raised it on direct appeal or in his first postconviction motion.
The court further held that Jackson could not avoid those procedural bars by characterizing Erlinger as a new constitutional rule. Following People v. Medina, the court concluded that Erlinger does not apply retroactively to cases on collateral review because its rule is neither substantive nor a watershed procedural rule.
The district court violated Rule 35(c)(3)(V) by soliciting a prosecution response without also serving the public defender after Jackson requested counsel, and compounded that error by barring Jackson from replying. But those errors—and any inadequacy in the district court’s written findings—were harmless because Jackson’s untimely and successive claim had to be denied as a matter of law.
Key Takeaways
- A constitutional attack on a sentence is governed by Rule 35(c), regardless of whether the defendant labels it an illegal-sentence claim under Rule 35(a).
- Erlinger does not apply retroactively to convictions and sentences already final on collateral review.
- A court that seeks a prosecution response to a Rule 35(c) motion must also serve the public defender when counsel has been requested, but violating that procedure may be harmless when procedural bars require denial.
Why It Matters
The decision reinforces that Erlinger does not reopen final Colorado habitual-criminal sentences through collateral review. Defendants whose convictions became final before Erlinger generally cannot use that decision to bypass Rule 35(c)’s timeliness and successive-claim restrictions.
The opinion also underscores the mandatory procedures for handling postconviction motions requesting counsel, while recognizing that procedural errors do not warrant reversal when the underlying claim is legally barred.
