The following are common grounds for appeal in Nevada criminal cases: The district court judge incorrectly applied a law or regulation (such as failing to sever a case when the joinder of multiple charges or co-defendants was prejudicial to the defendant); The judge made an incorrect ruling on the admissibility of evidence, which jeopardized the defendant's constitutional rights to a fair trial; There was insufficient evidence to support the gross misdemeanor or felony conviction; The jury was given improper instructions on the criminal charges; The deputy district attorney engaged in prosecutorial misconduct during the trial criminal proceedings. The Nevada Supreme Court decides only questions of law, not questions of fact. Questions of law concern whether the law was applied correctly. Questions of fact concern the truthfulness of evidence, such as the credibility of witnesses.
