Kent Richard Jones v. State of Minnesota, 883 N.W.2d 596

In 1992 Linda Jensen was murdered; Kent Jones later became a suspect after DNA linked him to the victim and inconsistent statements. Jones was convicted after a second trial in 2006; this Court affirmed and his conviction became final in 2008.
In August 2015—almost seven years after his direct appeal became final—Jones filed a petition for postconviction relief arguing medical literature and an opinion by a county medical examiner undermined the State’s trial medical expert.
The postconviction court denied the petition without an evidentiary hearing as untimely under Minn. Stat. § 590.01, subd. 4 (two‑year limitations period) and also cited the Knaffla rule barring claims known at direct appeal.
Jones argued the 2005 enactment of the postconviction limitations period could not constitutionally be applied to him because it would be an ex post facto law as to crimes committed in 1992.
He also argued Minn. Stat. § 631.21 (dismissal in the interest of justice) provides a statutory basis to bypass the postconviction limitations period in rare cases.
The Supreme Court affirmed: the petition was untimely, the statute of limitations is not an ex post facto law as applied to Jones, and § 631.21 does not apply to postconviction proceedings.

Issue	Jones' Argument	State's Argument	Held
Timeliness under Minn. Stat. § 590.01, subd. 4 (2‑year limit)	Petition filed in 2015 should be allowed because his claims warrant review	Petition is untimely: limitations period began when direct appeal final (2008) and no exception applies	Denied: petition untimely; summary dismissal proper
Ex post facto challenge to § 590.01, subd. 4	Applying the 2005 statute to crimes in 1992 is retroactive and unconstitutional	Statute applies only after conviction and final appeal; it did not operate retrospectively or alter criminal definitions/punishments/defenses	Rejected: statute not ex post facto as applied to Jones
Knaffla procedural bar (claims known at direct appeal)	(Alternate) Claims should be evaluated on merits because they show injustice	Knaffla bars claims known or discoverable at time of direct appeal	Court did not reach merits because untimeliness was dispositive (Knaffla not decided)
Applicability of Minn. Stat. § 631.21 (dismissal in furtherance of justice)	§ 631.21 allows courts to review extraordinary cases beyond postconviction time limits	§ 631.21 applies to pending criminal actions, not postconviction petitions after final conviction	Rejected: § 631.21 governs pre‑conviction dismissals and does not provide a postconviction bypass
