In the military justice system, a commander often performs a role that in the civilian world belongs to a judge: authorizing searches and seizures. Military Rule of Evidence 315 allows a commander to authorize a search of persons or property under the commander’s control based on probable cause. But that authority has limits, and when a commander’s authorization is invalid, the evidence obtained through it may be subject to suppression under Military Rule of Evidence 311. The consequences for the government’s case can be significant.
How commander search authorization works
A military commander may authorize a search of persons or property under the commander’s control when probable cause exists to believe that an offense has been committed and that evidence of it will be found in the place or on the person to be searched. The commander acts as the authorizing official, somewhat like a magistrate. There is no constitutional requirement that the person issuing a search authorization hold any particular legal or educational qualification, but the authorization must still rest on probable cause and the authorizing official must be neutral and detached rather than aligned with the investigative or prosecutorial effort.
An authorization can be invalid for several reasons. It may lack probable cause because the information presented to the commander was too thin, stale, or unreliable. The commander may not have been neutral and detached, for example if the commander was so personally involved in the investigation as to abandon the impartial role the rule requires. The authorization may have exceeded the commander’s control over the persons or property searched. Or the search as carried out may have exceeded the scope of what was authorized. Any of these defects can render the resulting search unlawful.
The rule that governs suppression
Military Rule of Evidence 311 is the suppression rule. It provides that evidence obtained as a result of an unlawful search or seizure made by a person acting in a governmental capacity is inadmissible against the accused if the accused makes a timely motion to suppress or objection to the evidence and the accused had an adequate privacy or property interest in the place or thing searched. In other words, an accused who can show a personal stake in what was searched, and who raises the issue properly, can ask the military judge to exclude evidence that flowed from an invalid authorization.
Who carries the burden
Once the defense makes an appropriate motion or objection, the burden shifts to the prosecution. The government must prove by a preponderance of the evidence that the evidence was not obtained as a result of an unlawful search or seizure, or that one of the recognized exceptions applies. Those exceptions include that the evidence would inevitably have been discovered or obtained even without the unlawful search, that the connection between the illegality and the evidence was sufficiently attenuated, or that officials reasonably and in good faith relied on an authorization or warrant that later proved defective. The defense ordinarily must raise a suppression motion before entering a plea, which makes timely litigation essential.
What suppression actually means
When the military judge agrees that a commander’s authorization was invalid and that no exception saves the evidence, the remedy is exclusion. The tainted evidence cannot be admitted against the accused in the case in chief. Just as important, the exclusionary principle can reach beyond the items physically seized. Evidence derived from the unlawful search, often called fruit of the poisonous tree, may also be suppressed if it would not have been discovered but for the illegality. That can include statements, leads, or additional evidence that the unlawful search made possible.
The practical effect depends on how central the suppressed evidence is. If the excluded items are the heart of the government’s proof, suppression can gut the prosecution and lead to dismissal of charges or a much weaker case at trial. If the evidence is peripheral, the case may proceed on other proof. This is why suppression litigation is often the decisive battleground in cases that turn on physical evidence, digital devices, or contraband seized under a commander’s authorization.
The limits and the exceptions
An invalid authorization does not guarantee that evidence will be thrown out. The good faith exception is particularly important in this context. If the officials executing the search reasonably relied in good faith on an authorization that appeared valid, the evidence may be admitted even though the authorization is later found defective, unless the defect was so obvious that reliance was unreasonable. Likewise, if the government can show that the same evidence would have been found through lawful, independent means, the inevitable discovery doctrine may preserve it. These doctrines mean that the validity of the authorization and the availability of an exception must both be analyzed.
What an accused should do
Because the rules governing search authorization, standing, burdens, and exceptions are technical and the deadlines are strict, a service member who believes evidence was gathered under a flawed commander authorization should raise the issue with defense counsel as early as possible. Counsel can investigate how the authorization was obtained, whether probable cause genuinely existed, whether the commander was neutral and detached, and whether the search stayed within its authorized scope. A well-supported suppression motion, filed on time, is often the strongest tool available to challenge the foundation of the government’s case.
