Search, Seizure, and Constitutional Protections
Search, Seizure, and Constitutional Protections
The exam tests Fourth Amendment doctrine as applied through the Military Rules of Evidence, especially MRE 311 through 317. You must know who can authorize a search, what facts supply probable cause, which warrant exceptions exist, and how inspections differ from criminal searches.
Authorization and probable cause
A probable cause search requires authorization from a neutral commander, military judge, or magistrate under MRE 315. The request must be particularized: place or person, items, and time. The authorizing official cannot be the investigator. Probable cause is a fair probability that evidence of a crime will be found in the place to be searched.
Warrant exceptions
MRE 314 recognizes consent, search incident to lawful apprehension, and exigent circumstances. Plain view and abandoned property are separate doctrines; administrative inspections are governed by MRE 313. Consent must be voluntary and may be limited or withdrawn. Apparent authority matters: a roommate may consent to common areas but not to a locked footlocker exclusively controlled by another. Exigency covers hot pursuit, destruction of evidence, and imminent danger.
Inspections and bodies
MRE 313 permits administrative inspections for health, welfare, and security. They require no probable cause but cannot be a subterfuge for criminal investigation. Body searches under MRE 312 range from pat-downs to intrusive searches; strip and body-cavity searches require probable cause, proper authorization, and medical personnel for cavity searches.
Digital devices
Phones and computers require particularized authorization. The scope should limit the date range, accounts, and data types. Plain view during a lawful device search does not automatically authorize a broader forensic examination.
Worked example
A commander authorizes a search of a soldier's barracks room for stolen electronics after an MP report and a witness statement. The scope covers the room and electronics, not the soldier's vehicle or phone. During the search, agents find a small bag of suspected marijuana in plain view on a shelf within the authorized area; seizing it is lawful because the incriminating character is immediately apparent. Searching the phone requires separate authorization.
Traps that cost marks
Treating a commander's general suspicion as probable cause. Using an inspection as a pretext. Overbroad consent. Failing to document consent or its withdrawal. Searching a digital device beyond the authorization.
