¶ 1. Andrе Bolden appeals from a judgment entered on a jury verdict convicting him of attеmpted robbery with the use of force, see Wis. Stat. §§ 943.32(1)(a) and 939.32, and from the trial court's order denying his mоtion for postconviction relief. He claims that his lawyer gave him ineffective assistance. We affirm.
I.
¶ 2. Bolden was charged and convicted for accosting Garrett Pauers and trying to rob him, but was interrupted when another person, Kurt Sampson, appeared. All three testified at the trial.
¶ 3. During Bolden's testimony, the State asked him about Pauers's earlier testimony, and, when Bolden contradicted that testimony, the State responded: "So Mr. Pauers is lying." 2 Bolden replied, "Right." The State asked Bolden a similar question about the testimony of police sergeant David Moldenhauer, who had testified about his interaction with Bolden: "So that's a lie." 3
¶ 4. The State also asked Bolden about Sampson's testimоny, and when Bolden indicated that he disagreed *856 with that testimony as well, the State asked: "He is lying?" When Bolden said that the officer was not telling the truth, the State responded:
Q. So if I understand, Mr. Bolden, out of the witnesses we heard in this trial, Mr. Pauers is either lying or mistaken about the faсt [sic; the State is referencing Bolden's version] that you guys had this mutually agreed-upon fight, is that fаir to say?
A. That's fair.
Q. And Mr. Sampson is mistaken in that you never were on top of Mr. Pauers and that you nеver were choking Mr. Pauers, is that fair to say?
A. That's fair to say.
Q. And that Mr. Sampson is mistaken in the sense that you weren't driving around on Meinecke shortly before this altercation with Mr. Pauers, is that fair to sаy?
A. Right.
Q. And that Sergeant Moldenhauer is mistaken when you mentioned anything about robbing Mr. Pauers?
A. Right.
¶ 5. Bolden faults his trial lawyer for not objecting to the State's questions, and, also, for not moving for а mistrial.
*857 II.
¶ 6. Every criminal defendant has a Sixth-Amendment right to the effective assistance of сounsel,
Strickland v. Washington,
¶ 7. In urging reversal, Bolden argues that
State v. Romero,
¶ 8. Both
Romero
and
Haseltine
held that the State may not bolster the credibility of its witnesses by asking someone with professional expertise to assess whether the witnesses are being truthful.
Romero,
¶ 9. Bolden argues, however, that
Jackson
was overruled by another court of appeals decision,
State v. Kuehl,
¶ 10. Although
Jackson
and
Kuehl
preceded
Cook,
this makes no difference.
Cook
based its ruling on "power" not policy. If the court of appeаls lacked the "power" to overrule or modify its prior decisions after
Cook,
it certainly also lacked that power before
Cook.
This was specifically recognized by
In re Court of Appeals,
which, as we have seen, noted in 1978 that a published decision by one panel was "binding" on the other panels.
See Garfoot v. Fireman's Fund Ins. Co.,
¶ 11. Kuehl lacked the power to overrule Jackson. Under Jackson, the State's questions here did not violate the Haseltine rule. Accordingly, Bolden's trial lawyer was not deficient for not objecting to those questions or moving for a mistrial.
By the Court. — Judgment and order affirmed.
