Background

Michigan State Police troopers found Kip Paul Mack sitting in a pickup truck without a license plate on the side of an Isabella County road. Mack said he had driven the truck before it overheated and acknowledged that he lacked insurance. A database search showed that the truck was uninsured and that its most recent registration, issued to someone else, had expired in 2019.

A jury convicted Mack of operating a motor vehicle without insurance and operating an unregistered vehicle. The trial court sentenced him to seven days in jail, with credit for three days served and the remaining four days suspended pending completion of probation. On appeal, Mack alleged ineffective assistance during jury selection, prosecutorial error in opening statements, and instructional error.

The Court’s Holding

The Court of Appeals affirmed. Defense counsel was not ineffective for declining to challenge a juror who initially suggested that police might possess greater expertise on vehicle matters. After the trial court clarified that the officers were not expert witnesses, the juror said he would weigh their testimony like that of any other witness and could decide the case impartially. Nor did Mack show that counsel’s broader approach to questioning prospective jurors about police bias was objectively unreasonable or prejudicial.

The prosecutor committed clear error by asking jurors to imagine being injured and left uncompensated by an uninsured driver or being unable to identify a fleeing vehicle without a license plate. The court characterized those hypotheticals as an improper appeal to fear and civic duty because they were unrelated to the facts of Mack’s case. But the unpreserved error did not warrant reversal: the jury was instructed that attorneys’ statements were not evidence and that its verdict must rest on the evidence and law, and the evidence of guilt was overwhelming and essentially undisputed.

Mack waived his challenge to the omission of offense elements from the preliminary jury instructions because defense counsel expressly stated that there was no objection after those instructions were read. The trial court later instructed the jury on the elements after the close of proofs.

Key Takeaways

  • A juror’s initial favorable view of police expertise did not establish ineffective assistance where the juror later affirmed impartiality and equal treatment of officer testimony.
  • Hypothetical accident scenarios designed to emphasize the social importance of insurance and registration laws were an improper appeal to jurors’ fears and civic duty.
  • The prosecutorial error was not outcome-determinative given the curative instructions and overwhelming, essentially undisputed evidence.
  • Defense counsel’s express approval of preliminary jury instructions waived appellate review of the claimed instructional error.

Why It Matters

The decision distinguishes between identifying prosecutorial error and obtaining relief from it. Even remarks the court deemed a textbook improper civic-duty appeal did not justify reversal under plain-error review when jury instructions addressed the risk of prejudice and the evidence of guilt was overwhelming.

The opinion also underscores the deference given to counsel’s jury-selection decisions and the appellate consequences of expressly approving jury instructions rather than merely failing to object.
