What are the legal standards for jury instructions in Texas criminal trials?
This question has been addressed in 4 Texas court opinions:
Brandon Keith Anderson v. The State of Texas
COA12 — January 30, 2026
In this case, a witness provided surprise testimony during a hearing involving prejudicial information that had not been disclosed during discovery. Although the defendant successfully moved the trial court to disregard the testimony, he did not specifically move for a mistrial. On appeal, the Twelfth Court of Appeals analyzed Texas Rule of Appellate Procedure 33.1(a) and the 'preservation ladder,' which generally requires a party to object, request an instruction to disregard, and move for a mistrial to preserve error. The court held that because the appellant received the exact relief he requested (disregarding the testimony) and failed to seek a mistrial or obtain an adverse ruling, the complaint was waived.
Litigation Takeaway
“Winning a motion to strike or disregard surprise testimony is a 'trap' if the evidence is truly 'incurable.' In Texas courts, if a witness drops a 'bombshell' that poisons the well, you must move for a mistrial and secure an adverse ruling to preserve the issue for appeal. Merely asking the judge to disregard the statement is considered a 'win' at trial that results in a procedural default on appeal, leaving you with no recourse if the judge is ultimately influenced by the excluded evidence.”
McKissick v. State
COA11 — February 20, 2026
After Johnathan McKissick was convicted of injury to a child, he appealed on the grounds of a 'material variance' because the child's name in the indictment (his birth name) differed from the name proven at trial (his adopted name). The Eleventh Court of Appeals analyzed whether this discrepancy prejudiced the defendant's defense or created a risk of double jeopardy under the Gollihar framework. The court held that the variance was immaterial because the defendant was not surprised by the identity of the victim and his defense was not hindered. Additionally, the court found no violation of discovery mandates under the Michael Morton Act, as the defendant had signed a discovery waiver and could not prove the State intentionally suppressed evidence discovered after the trial.
Litigation Takeaway
“A child's legal name change resulting from an adoption or termination proceeding does not create a 'material variance' that would invalidate a parallel criminal conviction, provided the defendant has notice of the victim's identity and is not prejudiced in their defense.”
Gannon v. The State of Texas
COA02 — February 5, 2026
After Dayton Joseph Gannon was convicted of aggravated robbery for brandishing a knife and aggressively posturing toward a victim through a laundromat's glass door, he appealed, arguing that the threat of injury was not 'imminent' because the victim was armed and separated from him by a physical barrier. The Second Court of Appeals analyzed the statutory meaning of 'imminent'—defined as 'near, at hand, or on the verge of happening'—and determined that a threat is judged by the aggressor's volatility and conduct rather than the victim's defensive capabilities. The court held that the display of a deadly weapon combined with combative posturing is sufficient to establish an imminent threat, regardless of whether the victim has a weapon or is behind glass.
Litigation Takeaway
“A threat of family violence remains 'imminent' even if the victim takes defensive measures or is separated from the aggressor by a barrier; the legal focus is on the aggressor's display of weaponry and volatility rather than the victim's relative safety.”
Johnson v. State
COA05 — February 23, 2026
A defendant convicted of possession with intent to deliver challenged his conviction, arguing that the State was required to prove he knew the specific chemical identity of the drugs (fentanyl) rather than just knowing he possessed a controlled substance (which he believed was oxycodone). The Fifth Court of Appeals analyzed the Texas Health & Safety Code and established precedent regarding culpable mental states, determining that the 'knowing' requirement applies to the illicit nature of the substance generally. The court held that the State must prove a defendant knew they possessed a controlled substance, but does not need to prove they knew its specific chemical name or potency. Additionally, the court ruled that trial courts are not required to define the 'floor' of the burden of proof by including 'clear and convincing' instructions in a criminal jury charge.
Litigation Takeaway
“In high-conflict custody or termination litigation, a parent cannot mitigate a 'knowing' endangerment finding by claiming they were mistaken about a drug's identity; knowledge that a substance is 'controlled' is sufficient to establish the mental state for endangerment regardless of the parent's subjective belief about its specific chemical composition or lethality.”
