Gary Curtis appeals from his convic-
tion for delivering drugs pursuant to §§ 161.41(l)(h)l and 161.41(l)(cm)l, STATS., 1993-94. 1 He contests several aspects of his trial. We consider the two most important issues to be whether it is necessary to have a Machner 2 hearing in every claim of ineffective assistance of counsel and whether voice identification may be used to authenticate one-party consent tapes. We begin with a brief review of the facts, address these two issues and then dispose of the other issues in this case.
First, Curtis claims that trial counsel was ineffective in failing to cite case law in his motion to suppress the tapes and in failing to request an in camera review of the tapes prior to their admission as evidence. Curtis acknowledges that the court of appeals has held that a postconviction
Machner
hearing is a prerequisite to a claim of ineffective assistance of counsel.
See State v. Machner,
We read
Machner
to preclude Curtis' interpretation. While the
Machner
court did not explicitly specify that a hearing was required in every case, we construe it to mean just that. The court held in
Machner
that "it is a prerequisite to a claim of ineffective representation on appeal to preserve the testimony of trial counsel."
Id.
The hearing is important not only to give trial counsel a chance to explain his or her actions, but also to allow the trial court, which is in the best position to judge counsel's performance, to rule on the motion. This dual purpose renders the hearing essential in every case where a claim of ineffective assistance of
Next, Curtis claims that the tapes admitted into evidence at trial were not properly authenticated. At trial, Poivey, a party to the conversations on the tapes, testified that the voices on the tapes were his and Curtis'. This type of voice identification is a valid avenue of authentication.
See United States v. Carrasco,
Curtis also attacks the use of the tapes on the theory that one-party consent tapes are legal only for investigative purposes and are not admissible as evidence. This used to be the law in Wisconsin, but the law had changed by the time the 1993 recordings were entered into evidence at Curtis' trial.
See, e.g., State v. Waste Management of Wis., Inc.,
Finally, we do not address Curtis' claim that the court erred in not allowing a witness to express an opinion on the truthfulness of one of the State's witnesses. The issue is inadequately briefed. This court need not review issues inadequately briefed.
See State v. Pettit,
By the Court. — Judgment affirmed.
Notes
These sections were renumbered to §§ 961.41(l)(h)l and 961.41(l)(cm), Stats., by 1995 Wisconsin'Act 448, § 244.
State v. Machner,
Our holding should not be construed to say that a defendant is automatically entitled to an evidentiary hearing no matter how cursory or meritless the ineffective assistance of counsel claim might be. As evident from reading
State v. Bentley,
Subsequent amendments have further broadened this authorization to all felonies. See 1993 Wis. Act 98, § 144; 1995 Wis. Act 30, § 1. However, these amendments were not effective until after Curtis' trial.
