8.8  Defendant’s Right to Have No Instruction on Defense

Comment

A defendant may have the right to have the trial court not instruct the jury on what may seem to be a defensive matter. In that case, the giving of an instruction may be error. The court of criminal appeals explained:

A defendant cannot waive submission of an element of the prosecution’s case to the finder of fact. But submission of a defensive issue is a strategic decision to be made by the defendant and his attorney. Not only is a defendant permitted to forego submission of a defensive issue, but he is also entitled to insist that a defensive issue not be submitted.

Williams v. State, 273 S.W.3d 200, 221 (Tex. Crim. App. 2008) (citing Posey v. State, 966 S.W.2d 57 (Tex. Crim. App. 1998), and Delgado v. State, 235 S.W.3d 244 (Tex. Crim. App. 2007)).

Some of what are generally regarded as defensive matters may, at least as applied to some situations, favor the state. A proper instruction on voluntary intoxication, for example, is really an instruction that there is no defense of this sort.

A mistake-of-fact instruction might be construed as telling the jury to give less significance to evidence of an unreasonable mistake of fact than the defendant would like. Failure of the instructions to address the matter may permit the defendant to explicitly or implicitly argue to the jury a more favorable version of the legal standard than the law provides. A mistake-of-fact instruction, then, may at least sometimes favor the state.

Consequently, and despite the Williams discussion, the state may sometimes have a right to a jury charge on some defensive matters over the defendant’s objection. Clearly, whether a voluntary intoxication instruction is given cannot depend on the defendant’s preference. Perhaps the same is the case regarding mistake of fact.
