The “Automobile Exception” in Michigan law

The “automobile exception” in Michigan law allows police to search a vehicle without a warrant if they have probable cause to believe it contains evidence of a crime.

This exception is grounded in the idea that vehicles are inherently mobile, meaning evidence could be moved or destroyed before a warrant is obtained.

Probable cause is a key element in applying this exception.

If law enforcement has a reasonable belief—based on the facts and circumstances—that the vehicle contains contraband or evidence of illegal activity, they can conduct a search.

This standard often arises in cases involving drug-related offenses.

For example, the smell of marijuana has frequently been cited as a factor contributing to probable cause, although recent rulings have added complexity due to the legalization of marijuana in small amounts under Michigan law.

One notable case is People v. Kazmierczak (2000), where the Michigan Supreme Court ruled that the smell of marijuana alone could justify a search under the automobile exception.

However, as marijuana laws evolved, this principle was reconsidered.

In People v. Armstrong (2023), the court ruled that while the smell of marijuana can contribute to probable cause, it must be combined with other suspicious factors to justify a search.

The debate around this exception continues as courts balance law enforcement’s ability to investigate crimes and individuals’ privacy rights, especially with the legalization of marijuana in Michigan.

Cases

Several legal cases have examined the validity of conducting warrantless vehicle searches based on the odor of marijuana, particularly considering the changing landscape of marijuana legislation.

People v. Freddie Wilkins III (2024):  In Wilkins’ case, the search was triggered by the odor of marijuana, but his defense challenged whether that alone should constitute probable cause for a broader search, particularly when possession of small amounts of marijuana is legal.

People v. Armstrong (2023): In this instance, the courts in Michigan reassessed the applicability of the automobile exception, taking into consideration the provisions outlined in the Michigan Regulation and Taxation of Marihuana Act (MRTMA).

The court ruled that while the smell of marijuana could still contribute to probable cause, it must be accompanied by other suspicious factors to justify a search. This case closely mirrors Wilkins, where the search was based on marijuana odor but also raised questions about unregistered firearms found during the search​.

People v. Moorman (2020): During a traffic stop, a police officer detected the scent of marijuana, and when the defendant denied possessing any, this denial, along with the odor, provided the officer with probable cause to conduct a search of the vehicle.

The court found that the defendant’s behavior, along with the odor, justified the search, similar to the arguments presented in Wilkins. The ruling was based on the idea that such behavior suggests illegal possession beyond the legal limits​

People v. Kazmierczak (2000): Previously, Michigan courts held that the smell of marijuana alone was sufficient to establish probable cause for a vehicle search.

However, this decision was later overruled in part due to changes in marijuana laws.

This case laid the groundwork for discussions like those in Wilkins, where courts must determine if the presence of marijuana (legal in small amounts) is enough to justify a search​.
