OPINION
Appellant Vernon Neal Powers filed a motion for correction of sentence, pursuant to Minn. R.Crim. P. 27.03, in Mower County District Court. The district court treated the motion as Powers’ third petition for postconviction relief and denied the motion without a hearing. Powers appealed to this court, arguing that the district court erred when it denied the motion. We affirm.
The facts of the underlying crime in this case are set forth in detail in
State v. Powers,
Powers commenced the instant action by filing a motion for correction of sentence, pursuant to Minn. R.Crim. P. 27.03. Pow
*501
ers’ motion argued that
Blakely v. Washington,
A postconviction court shall order an evidentiary hearing “[ujnless the petition and the files and records of the proceeding conclusively show that the petitioner is entitled to no relief.” Minn.Stat. § 590.04, subd. 1 (2006). The postconviction petition, however, must include “ ‘more than argumentative assertions without factual support.’ ”
Hodgson v. State,
On review of a postconviction decision, we determine whether there is sufficient evidence to support the postconviction court’s findings.
White v. State,
It is well settled that when, as in this case, “direct appeal has once been taken, all matters raised therein, and all claims known but not raised, will not be considered upon a subsequent petition for postconviction relief.”
Knaffla,
We hold that Knaffla bars Powers’ claims. Powers raised his sentencing argument based on Apprendi in his first postconviction petition. Powers’ current claim is essentially the same claim, but he cites Blakely in support of his argument as well as Apprendi. Powers does not explain how Blakely has changed his sentencing argument. Moreover, to the extent that the sentencing claim is different *502 based on Blakely, it is KnaffUt-barred because Powers could have raised it in his second petition for postconviction relief. 3
There are two exceptions to the
Knajfla
rule: (1) if a novel legal issue is presented, or (2) if the interests of justice require review.
Perry v. State,
Powers also argues, for the first time in his brief to this court, that the sentencing guidelines are unconstitutional because they were enacted by the Minnesota Sentencing Guidelines Commission, rather than by the legislature. We are “most reluctant” to address issues that were not raised at the district court,
State v. Sorenson,
We hold that the district court did not abuse its discretion in dismissing, without hearing, Powers’ motion for a correction of sentence.
Affirmed.
Notes
. Powers has not made this argument to this court. Therefore, we need not address it. We note, however, that
Recuenco
did not address the retroactive application of
Blakely,
and the Supreme Court pointed out that both
Apprendi
and
Blakely
were decided before the Washington Supreme Court heard the case on direct appeal.
Recuenco,
. Powers does not challenge the district court’s decision to treat his motion as a petition for postconviction relief. The district court’s decision finds support in the language of Minn.Stat. § 590.01, which is broad enough to encompass a motion pursuant to Minn. R.Crim. P. 27.03.
See
Minn.Stat. § 590.01 (2006) (allowing a convicted person to petition the district court to correct a sentence); Minn. R.Crim. P. 27.03, subd. 9 ("The court at any time may correct a sentence not authorized by law.");
see also State v. Stutelberg,
. Blakely was decided on June 24, 2004, so Powers knew, or should have known, to raise his arguments with respect to Blakely when he filed his second postconviction petition on November 3, 2004.
. Even if we chose to address Powers’ argument, we would conclude that the argument is Knaffla-barred because he could have raised it on direct appeal.
