Background

Timothy Edward Headley was convicted of four counts of first-degree criminal sexual conduct based on allegations that he sexually assaulted his stepdaughter, CC. The charging document alleged penile-vaginal and/or penile-oral penetration. CC testified to penile-vaginal penetration and also said that Headley’s penis touched the area around her mouth and touched and moved her lips, but she was not asked whether it entered her mouth.

The jury was instructed that each count could be established by entry into CC’s genital opening or mouth and that its verdict had to be unanimous, but it did not receive a specific-unanimity instruction requiring agreement on the particular act supporting each conviction. After receiving concurrent sentences of 15 to 30 years, Headley sought a new trial based on insufficient evidence of penile-oral penetration and ineffective assistance arising from counsel’s failure to object to the instructions or request a specific-unanimity instruction. The trial court granted a new trial on both grounds, and the prosecution appealed by leave granted.

The Court’s Holding

The Michigan Court of Appeals affirmed the order granting Headley a new trial. The trial court had treated counsel’s failure to request a specific-unanimity instruction as an independent basis for relief, regardless of whether the evidence sufficiently established penile-oral penetration.

Because the prosecution did not challenge that ineffective-assistance ruling on appeal, the Court of Appeals concluded that the trial court did not abuse its discretion by granting a new trial on that unchallenged ground. The court therefore declined to decide the prosecution’s arguments concerning evidentiary sufficiency and alleged judicial prejudice.

The court added that, if Headley is retried on a penile-oral-penetration theory, the trial court must apply binding Michigan precedent defining fellatio as requiring actual penetration or intrusion of the penis into the mouth, rather than mere contact.

Key Takeaways

  • An appellant must challenge every independent ground supporting the order under review; leaving one dispositive basis unanswered can require affirmance.
  • The new-trial order stood because the prosecution did not contest the trial court’s ineffective-assistance ruling concerning counsel’s failure to request a specific-unanimity instruction.
  • For any retrial based on a fellatio theory, Michigan precedent requires actual penetration of the mouth, not merely external contact with the lips or mouth area.

Why It Matters

The decision underscores the appellate consequence of failing to address an independently sufficient ruling below. Even substantial arguments directed at other grounds will not obtain reversal when an unchallenged basis continues to support the judgment.

It also gives the trial court concrete guidance for any retrial: a penile-oral theory of first-degree criminal sexual conduct must be evaluated under the binding definition of fellatio requiring actual oral penetration.
