OPINION
In this appeal, Jon Earl Quick challenges the posteonviction court’s denial of his second petition for posteonviction relief. In the petition, Quick claims that: (1) he received ineffective assistance of trial counsel; (2) this court erred on direct appeal by using the wrong standard to affirm the exclusion of three defense witnesses; (3) he was incompetent to stand trial; (4) new evidence that the crime scene team leader was recently convicted of a controlled substance crime requires an eviden-
Quick was convicted of first-degree premeditated murder for the September 14, 2000, killing
of
Justin Mueller and was sentenced to life imprisonment. We affirmed Quick’s conviction on direct appeal, holding that there was sufficient evidence for the jury to conclude that Quick acted with premeditation and without heat of passion; that he was not denied the right to present a defense and a fair trial by the exclusion of testimony from three witnesses; that his claims of ineffective assistance of trial counsel were either not reasonable or were unsupported by the record; that his claims of prosecutorial misconduct were without merit; and that a number of other claims raised on direct appeal were also without merit.
State v. Quick (Quick I),
Quick subsequently petitioned for post-conviction relief, which the postconviction court summarily denied, and we affirmed the postconviction court.
Quick v. State (Quick II),
In this appeal, Quick claims that his trial counsel was ineffective because counsel failed to: (1) effectively argue
for
the testimony of three excluded defense witnesses; (2) consult with Quick about the Rule 20 psychological report and address supposed errors in the report; (3) raise a medical defense based on Quick’s diabetic condition; (4) object to a jury instruction defining heat of passion; and (5) provide Quick with his case file after the trial. Under
Knaffla,
when “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.” 309 Minn, at 252,
A review of the record indicates that, except for the claim that Quick’s trial counsel failed to provide Quick with his case file after trial, the facts underlying each of Quick’s ineffective-assistance-of-counsel claims were known and raised on direct appeal, or were either known or should have been known but were not
Knaffla also bars Quick’s claim that we applied the wrong harmless error standard when reviewing the trial court’s exclusion of defense witnesses. Because the supposed error occurred on direct appeal, Quick either knew or should have known about this claim at the time of his first petition for postconviction relief. Similarly, Quick’s claim that he was incompetent to stand trial, based on the Rule 20 examination, is also procedurally barred. The claim should have been raised on direct appeal because the Rule 20 examination occurred before trial. None of Quick’s claims fall within either of Knaff-la’s two exceptions.
Quick’s argument that the post-conviction court abused its discretion when it denied relief without an evidentiary hearing on the above claims is without merit. We review a postconvietion court’s denial of postconviction relief without a hearing for an abuse of discretion.
See Jones v. State,
Quick also argues that an eviden-tiary hearing should have been held to review his claim of newly discovered evidence that the team leader who investigated the Quick crime scene pleaded guilty in 2005 to first-degree drug possession. Newly discovered evidence will only lead to a new trial if the evidence: (1) was not within petitioner’s or his counsel’s knowledge before trial; (2) could not have been discovered through due diligence before trial; (3) is not cumulative, impeaching, or doubtful evidence; and (4) would probably produce a different or more favorable result.
Wieland v. State,
First, [the team leader’s] conviction for drug possession is impeachment evidence. Impeachment evidence is not grounds for a new trial. Second, Petitioner has not established that this evidence would have changed the outcome of his trial. Petitioner’s trial was held in October 2001 and [the team leader] pleaded guilty to drug possession in 2005. There is no evidence that [the team leader] was using drugs or involved in any criminal conduct at the time of Petitioner’s trial. In addition, [the team leader’s] testimony at trial consisted of him describing the crime scene and laying foundation for the admission of videotape and photos taken by investigators. His testimony was not disputed by the defense.
(Citation omitted.) We agree. Given that this evidence was merely impeaching and would not produce a different or more favorable result for Quick, no evidentiary hearing was required.
Affirmed.
