People v. Koon
818 N.W.2d 473
Mich. Ct. App.2012Background
- Question whether the so‑called zero‑tolerance provision (MCL 257.625(8)) applies where the driver used marijuana under MMMA.
- Defendant admitted recent marijuana use (MMMA registry card) and had active THC; blood test showed active marijuana.
- Defendant was charged with operating a vehicle with any amount of a schedule 1 substance in the body under the zero‑tolerance statute.
- Lower courts split: district court: MMMA protects only if not impaired; circuit court: MMMA supersedes zero tolerance.
- Court holds MMMA does not repeal or supersede the zero‑tolerance provision; marijuana remains schedule 1; conviction upheld as proper under MCL 257.625(8).
- Reversal was granted historically on direct reasoning but final disposition: reversed and remanded for further proceedings consistent with this opinion.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether MMMA immunizes driving with marijuana in the body. | People argued MMMA provides immunity from prosecution. | Defendant contends MMMA defeats enforcement of MCL 257.625(8). | MMMA does not provide immunity; zero‑tolerance stands. |
| How to interpret 'under the influence' in this context. | N/A (not framed as plaintiff’s alternative interpretation). | MMMA does not redefine or repeal 'under the influence' in the Vehicle Code. | MCL 257.625(8) defines any amount in the body as influencing driving; MMMA does not override it. |
