State of Montana v. Grant Alan West

2026 MT 13 · Supreme Court of Montana · February 3, 2026 · No. DA 23-0137

Summary

The Montana Supreme Court affirmed Grant Alan West’s convictions for robbery, aggravated kidnapping, and criminal possession of dangerous drugs. The court rejected his claims concerning delayed disclosure of a witness’s hearing impairment, insufficiency of the robbery evidence, prosecutorial misconduct, ineffective assistance of counsel, and cumulative error.

Holdings

  1. The three-day delay in disclosing Coker's hearing impairment did not establish a Brady violation requiring exclusion of her testimony because West had the opportunity to cross-examine her and failed to show a reasonable probability that earlier disclosure would have changed the verdict.
  2. The evidence was sufficient for a rational juror to find beyond a reasonable doubt that West committed robbery.
  3. West waived his challenge to testimony about his alleged drug addiction by failing to object at trial and by raising plain error for the first time in his reply brief.
  4. The State's use of the overlay video during closing argument did not warrant reversal because, on the record available, West failed to demonstrate that the prosecutor's use of the admitted videos and related argument prejudiced his substantial rights.
  5. West's ineffective-assistance claims were not appropriate for review on direct appeal because the record did not reveal counsel's reasons for the alleged omissions.
  6. The cumulative-error doctrine did not apply because West failed to establish individual error or resulting prejudice.

Questions Presented

  1. Whether the State's three-day delay in disclosing that a key witness was hearing impaired violated Brady and required exclusion of the witness's testimony.
  2. Whether the evidence, viewed in the light most favorable to the prosecution, was sufficient for a rational juror to find the essential elements of robbery beyond a reasonable doubt.
  3. Whether the State committed reversible prosecutorial misconduct by eliciting testimony concerning West's alleged drug addiction or by displaying an overlay of two surveillance videos during closing argument.
  4. Whether West's ineffective-assistance claims could be reviewed on direct appeal.
  5. Whether cumulative error deprived West of a fair trial.
