How is constructive possession evaluated in Article 112a drug use cases?

Article 112a of the Uniform Code of Military Justice criminalizes the wrongful use, possession, manufacture, distribution, and importation of controlled substances. Possession cases are often the most fact-intensive of these, because controlled substances are not always found in a member’s hand or pocket. They may be found in a shared vehicle, a common barracks room, a jointly used locker, or a residence with several occupants. In those situations the government relies on a theory called constructive possession. Evaluating that theory correctly is essential, because constructive possession turns on proof of two things the prosecution frequently struggles to establish: knowledge and control.

What possession means under Article 112a

To possess a substance under Article 112a means to exercise control over it. Possession comes in two forms. Actual possession is direct physical custody, such as holding the substance or carrying it on one’s person. Constructive possession exists when a member does not have the substance physically on them but still has the power and the intention to exercise control over it, such as keeping it in a safe, a car, or a room to which the member can return. Both forms can support a conviction, but constructive possession requires the government to build an inference of control from circumstances rather than from direct physical custody.

The two pillars: knowledge and control

Constructive possession under Article 112a is evaluated through two essential elements. The first is knowledge. The member must have known that the substance was present and known of its contraband nature. Possession must be knowing and conscious. A person cannot be convicted of possessing a controlled substance that the person did not know was there. The second is control, sometimes described as dominion and control. The member must have had the power and the intention to exercise control over the substance, either alone or jointly with others.

Both elements must be present. Mere knowledge that drugs exist somewhere nearby, without the power to control them, is not possession. Likewise, access to a space where drugs happen to be located, without knowledge of their presence, is not possession. The government must connect the member to the substance through both awareness and the ability to control it.

Why proximity alone is not enough

A central principle in constructive possession analysis is that mere presence near a controlled substance, or mere access to the place where it is found, does not by itself establish possession. This principle does most of the protective work in shared-space cases. If a substance is found in a vehicle occupied by several people, the location of the drugs near one occupant does not automatically make that occupant a possessor. The same is true for a barracks room, an apartment, or a locker that more than one person can reach.

To move from proximity to possession, the government must supply additional facts that show the particular member both knew of the substance and had the power to control it. Without that bridge, a possession charge built on location alone is vulnerable.

The circumstantial factors fact finders weigh

Because constructive possession is usually proved by circumstantial evidence, fact finders and military judges look at the totality of the circumstances. Relevant considerations commonly include how close the member was to the substance, whether the member had exclusive or shared access to the place where it was found, whether the substance was in plain view or hidden, whether the member’s belongings were intermingled with the substance, whether the member made statements or behaved in a way suggesting awareness, and whether other evidence tied the member specifically to the contraband. No single factor is decisive. The question is always whether the combination of facts supports a reasonable inference, beyond a reasonable doubt, that this member knew the substance was present and had the power and intention to control it.

Joint possession and its limits

Possession can be joint. More than one person can constructively possess the same substance at the same time if each has the requisite knowledge and control. But joint possession is not a presumption. The government cannot simply attribute possession to everyone who had access to a shared space. It must prove the knowledge and control elements as to each individual it charges. This is why constructive possession cases involving several occupants often turn on which member the evidence specifically connects to the contraband.

Common defenses in constructive possession cases

The defense in a constructive possession case typically attacks one of the two pillars. A lack-of-knowledge defense argues that the member did not know the substance was present or did not know it was contraband. A lack-of-control defense argues that the member had no power or intention to exercise control over it, often emphasizing shared access, the presence of others with equal or greater connection to the substance, and the absence of any link between the member and the drugs beyond mere proximity. The defense may also stress that the substance was hidden, that it belonged to someone else, or that the member’s access to the space was incidental.

The bottom line

Constructive possession in an Article 112a case is evaluated by asking whether the member knew a controlled substance was present and had the power and intention to control it. Physical custody is not required, but proof of both knowledge and dominion is. Mere presence near the substance or access to the place where it is found is not enough. The government must use the surrounding circumstances to build a reasonable inference of awareness and control as to the specific member charged, and where that inference is weak, especially in shared vehicles or living spaces, a constructive possession theory can fail.
