Case Summary

Juan Montellano v. the State of Texas, decided by Texas Court of Appeals on March 30, 2026, resulted in a defendant win outcome. The appellant, Juan Montellano, was convicted of aggravated assault with a deadly weapon. He appealed, arguing that the trial court erred by admitting evidence of his prior "bad acts" and by failing to instruct the jury on the lesser included offense of aggravated assault. The appellate court affirmed the conviction, finding that the "bad acts" evidence was admissible for impeachment purposes and that the evidence did not support a jury instruction on the lesser included offense. The court held: Evidence of prior "bad acts" is admissible for impeachment purposes if the defendant testifies and the evidence is relevant to their credibility.. A jury instruction on a lesser included offense is only required if there is evidence that the defendant committed the lesser offense but not the greater offense.. The trial court did not err in admitting evidence of prior "bad acts" when the defendant chose to testify and put his credibility at issue.. This case reinforces the established Texas evidentiary rules regarding the impeachment of a defendant's testimony with prior "bad acts" and the standard for granting jury instructions on lesser included offenses. It highlights the strategic importance of a defendant's decision to testify and the careful balancing act courts must perform when admitting potentially prejudicial evidence.

If the defendant does not testify, the rules for admitting such evidence are much stricter.
