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 an objection to the evidence under this rule;

the accused had a reasonable expectation of privacy in the person, place, or property searched; the accused had a legitimate interest in the property or evidence seized when challenging a seizure; or the accused would otherwise have grounds to object to the search or seizure under the Constitution of the United States as applied to members of the Armed Forces; and

exclusion of the evidence results in appreciable deterrence of future unlawful searches or seizures and the benefits of such deterrence outweigh the costs to the justice system.

As used in this rule, a search or seizure is "unlawful" if it was conducted, instigated, or participated in by:

military personnel or their agents and was in violation of the Constitution of the United States as applied to members of the Armed Forces, a federal statute applicable to trials by court-martial that requires exclusion of evidence obtained in violation thereof, or Mil. R. Evid. 312-317;

other officials or agents of the United States, of the District of Columbia, or of a State, Commonwealth, or possession of the United States or any political subdivision of such a State, Commonwealth, or possession, and was in violation of the Constitution of the United States, or is unlawful under the principles of law generally applied in the trial of criminal cases in the United States district courts involving a similar search or seizure; or

officials of a foreign government or their agents, where evidence was obtained as a result of a foreign search or seizure that subjected the accused to gross and brutal maltreatment. A search or seizure is not "participated in" by a United States military or civilian official merely because that person is present at a search or seizure conducted in a foreign nation by officials of a foreign government or their agents, or because that person acted as an interpreter or took steps to mitigate damage to property or physical harm during the foreign search or seizure.

Evidence that was obtained as a result of an unlawful search or seizure may be used to impeach by contradiction the in-court testimony of the accused.

Evidence that was obtained as a result of an unlawful search or seizure may be used when the evidence would have been obtained even if such unlawful search or seizure had not been made.

Evidence that was obtained as a result of an unlawful search or seizure may be used if:

the search or seizure resulted from an authorization to search, seize, or apprehend issued by an individual competent to issue the authorization under Mil. R. Evid. 315(d) or from a search warrant or arrest warrant issued by competent civilian authority, or from such an authorization or warrant issued by an individual whom the officials seeking and executing the authorization or warrant reasonably and with good faith believed was competent to issue the authorization or warrant;

the individual issuing the authorization or warrant had a substantial basis for determining the existence of probable cause or the officials seeking and executing the authorization or warrant reasonably and with good faith believed that the individual issuing the authorization or warrant had a substantial basis for determining the existence of probable cause; and

the officials seeking and executing the authorization or warrant reasonably and with good faith relied on the issuance of the authorization or warrant. Good faith is to be determined using an objective standard.

See U.S. v. Perkins, 78 M.J. 381 (C.A.A.F. 2019).

Evidence that was obtained as a result of an unlawful search or seizure may be used when the official seeking the evidence acted in objectively reasonable reliance on a statute or on binding precedent later held violative of the Fourth Amendment.

Prior to arraignment, the prosecution must disclose to the defense all evidence seized from the person or property of the accused, or believed to be owned by the accused, or evidence derived therefrom, that it intends to offer into evidence against the accused at trial.

When evidence has been disclosed prior to arraignment under subdivision (d)(1), the defense must make any motion to suppress or objection under this rule prior to submission of a plea. In the absence of such motion or objection, the defense may not raise the issue at a later time except as permitted by the military judge for good cause shown. Failure to so move or object constitutes a waiver of the motion or objection.

If the prosecution intends to offer evidence described in subdivision (d)(1) that was not disclosed prior to arraignment, the prosecution must provide timely notice to the military judge and to counsel for the accused. The defense may enter an objection at that time and the military judge may make such orders as are required in the interest of justice.

The military judge may require the defense to specify the grounds upon which the defense moves to suppress or object to evidence described in subdivision (d)(1). If defense counsel, despite the exercise of due diligence, has been unable to interview adequately those persons involved in the search or seizure, the military judge may enter any order required by the interests of justice, including authorization for the defense to make a general motion to suppress or a general objection.

If the defense challenges evidence seized pursuant to a search warrant or search authorization on the ground that the warrant or authorization was not based upon probable cause, the evidence relevant to the motion is limited to evidence concerning the information actually presented to or otherwise known by the authorizing officer, except as provided in subdivision (d)(4)(B).

If the defense makes a substantial preliminary showing that a government agent knowingly and intentionally or with reckless disregard for the truth included a false statement or omitted a material fact in the information presented to the authorizing officer, and if the allegedly false statement or omitted material fact is necessary to the finding of probable cause, the defense, upon request, is entitled to a hearing. At the hearing, the defense has the burden of establishing by a preponderance of the evidence the allegation of knowing and intentional falsity or reckless disregard for the truth. If the defense meets its burden, the prosecution has the burden of proving by a preponderance of the evidence, with the false information set aside, that the remaining information presented to the authorizing officer is sufficient to establish probable cause. If the prosecution does not meet its burden, the objection or motion must be granted unless the search is otherwise lawful under these rules.

When the defense makes an appropriate motion or objection under subdivision (d), the prosecution has the burden of proving by a preponderance of the evidence that the evidence was not obtained as a result of an unlawful search or seizure; that the evidence would have been obtained even if the unlawful search or seizure had not been made; that the evidence was obtained by officials who reasonably and with good faith relied on the issuance of an authorization to search, seize, or apprehend or a search warrant or an arrest warrant; that the evidence was obtained by officials in objectively reasonable reliance on a statute or on binding precedent later held violative of the Fourth Amendment; or that the deterrence of future unlawful searches or seizures is not appreciable or such deterrence does not outweigh the costs to the justice system of excluding the evidence.

In addition to subdivision (d)(5)(A), a statement obtained from a person apprehended in a dwelling in violation of R.C.M. 302(d)(2) and (e), is admissible if the prosecution shows by a preponderance of the evidence that the apprehension was based on probable cause, the statement was made at a location outside the dwelling subsequent to the apprehension, and the statement was otherwise in compliance with these rules.

When the military judge has required the defense to make a specific motion or objection under subdivision (d)(3), the burden on the prosecution extends only to the grounds upon which the defense moved to suppress or objected to the evidence.

The defense may present evidence relevant to the admissibility of evidence as to which there has been an appropriate motion or objection under this rule. An accused may testify for the limited purpose of contesting the legality of the search or seizure giving rise to the challenged evidence. Prior to the introduction of such testimony by the accused, the defense must inform the military judge that the testimony is offered under subdivision (d). When the accused testifies under subdivision (d), the accused may be cross-examined only as to the matter on which he or she testifies. Nothing said by the accused on either direct or cross-examination may be used against the accused for any purpose other than in a prosecution for perjury, false swearing, or the making of a false official statement.

The military judge must rule, prior to plea, upon any motion to suppress or objection to evidence made prior to plea unless, for good cause, the military judge orders that the ruling be deferred for determination at trial or after findings. The military judge may not defer ruling if doing so adversely affects a party's right to appeal the ruling. The military judge must state essential findings of fact on the record when the ruling involves factual issues.

If a defense motion or objection under this rule is sustained in whole or in part, the court-martial members may not be informed of that fact except when the military judge must instruct the members to disregard evidence.

Except as otherwise expressly provided in R.C.M. 910(a)(2), a plea of guilty to an offense that results in a finding of guilty waives all issues under the Fourth Amendment to the Constitution of the United States and Mil. R. Evid. 311-317 with respect to the offense, whether or not raised prior to plea.
