State v. Martinez Castellanos, 2018 UT 46 (Aug. 29, 2018)

The court overturned a court of appeals decision ordering a new trial due to the cumulative errors at the district court.  The court held that under the cumulative error doctrine, only those errors that are substantial enough to cause harm can accumulate.  Minor errors that could result in no harm do not accumulate so as to warrant a new trial.
