Another objection to UCrJI 1006

by: Ryan Scott • January 8, 2026 • no comments

In the preceding post, I argued why the standard jury instruction UCrJI 1006 violates the rules against commenting on the evidence and vouching, because it tells the jury that the witnesses have taken an oath to tell the truth, thereby drawing the jury's attention to a reason to believe those witnesses..

But that's not the only problem with UCrJI 1006.

The standard UCrJI 1006 (“Evaluating Witness Testimony”) instruction states:

The term witness includes every person who has testified under oath in this case. Every witness has taken an oath to tell the truth. In evaluating each witness’s testimony, however, you may consider such things as: (1) The manner in which the witness testifies. (2) The nature or quality of the witness’s testimony. (3) Evidence that contradicts the testimony of the witness. (4) Evidence concerning the bias, motives, or interest of the witness. [(5) Evidence concerning the character of the witness for truthfulness.] “[(6) Evidence that the witness has been convicted of a previous crime.].”

(6) is also an impermissible comment on the evidence because it highlights a fact that the jury is supposed to consider for a particular purpose. Now this one gets more complicated strategically. Obviously, you only want to object when your client's conviction comes into evidence. But there are other considerations, including whether to ask for a limiting instruction that limits what purposes the jury can consider the prior conviction for.
