State v. Mata

321 Neb. 566 (2026) · Nebraska Supreme Court · June 18, 2026 · No. S-24-664

Summary

The Nebraska Supreme Court affirmed the dismissal of Raymond Mata Jr.’s successive motion for postconviction relief as procedurally barred. The court addressed alleged conflicts of interest involving his initial postconviction counsel and trial counsel, the exclusion of proposed exhibits, waiver, and whether the successive motion constituted Mata’s first meaningful opportunity to raise ineffective-assistance claims.

Holdings

  1. Any error in excluding Mata's exhibits was harmless because the excluded material was cumulative and other properly admitted evidence supported the district court's finding that initial postconviction counsel had no actual conflict of interest.
  2. Mata failed to establish that Straetker had an actual conflict of interest based on his former service as an NCPA commissioner, public-defender incentives, alleged advice to accept NCPA representation, or prior representation of the victim's grandfather.
  3. Mata was not entitled to pursue a successive postconviction motion under Williams because he failed to show that his initial postconviction counsel had an actual conflict preventing counsel from raising the claims.
  4. All of Mata's claims except his claim of ineffective assistance of postconviction counsel were procedurally barred because they could have been raised on direct appeal or in the initial postconviction proceeding; the ineffective-assistance claim concerning postconviction counsel was not cognizable.

Questions Presented

  1. Whether the district court improperly excluded or excluded cumulative exhibits offered at the evidentiary hearing.
  2. Whether alleged conflicts involving initial postconviction counsel made Mata's successive postconviction motion his first opportunity to raise claims under State v. Williams.
  3. Whether alleged conflicts involving trial counsel required relief or permitted a successive postconviction proceeding.
  4. Whether Mata's remaining claims were procedurally barred or noncognizable and therefore could be dismissed without a further merits hearing.

Disposition

affirmed
