Opinion of the Court
Appellant was tried by a special court-martial composed of officer and enlisted members during November 1984. Contrary to his pleas, he was found guilty of one specification alleging wrongful use of marihuana, in violation of Article 112a, Uniform Code of Military Justice, 10 U.S.C. § 912a. He was sentenced to a bad-conduct discharge, confinement for 30 days, forfeiture of $397 pay per month for 1 month, and reduction to E-l. The convening authority approved this sentence. On June 28,1985, the Court of Military Review affirmed.
We granted review of the following issue:
WHETHER THE RESULTS OF URINALYSIS TESTS ALONE ARE SUFFICIENT UNDER THE CIRCUMSTANCES OF THIS CASE, AS A MATTER OF LAW, TO SUSTAIN A FINDING OF GUILTY TO WRONGFUL USE OF MARIHUANA.
This Court has previously held that evidence of urinalysis tests, their results, and expert testimony explaining them is sufficient to show beyond a reasonable doubt that an accused used marihuana. We also have recognized that military law for over 35 years has provided that a permissive inference of wrongfulness may be drawn from such a circumstantial showing of marihuana use. See United States v. Harper,
The prosecution based its case against appellant on the results of various laboratory tests on his urine and expert testimony explaining them. It evidenced the procedures involved in taking the sample, its security and transportation to the laboratory, the procedures at the laboratory, the tests performed, and the results of those tests. It also called a chemist from the laboratory to explain the tests and interpret the results in terms of ingestion of marihuana.
Appellant took the stand and denied using marihuana during the period in question. He asserted that he did not possess or use marihuana, never ate any food that he knew contained marihuana, and had no direct knowledge of how or why his sample came up positive. He explained the test results by suggesting that the laboratory made a mistake or his estranged wife, who was aware of the urinalysis program, planted marihuana in his food. He called several witnesses who testified that they observed no abnormalities in his behavior suggesting drug abuse. He also called a family friend who testified to his wife’s unhappiness with the marriage and the military, her occasional possession of marihuana, and her opportunity to plant this substance in his food.
INFERENCE OF WRONGFULNESS
The prosecution was required to prove beyond a reasonable doubt that appellant “wrongfully” used marihuana. Art. 112a. Wrongful use in the context of Article 134,
In proving wrongfulness, including knowledge,
This Manual provision states:
(5) Wrongfulness. To be punishable under Article 112a, possession, use, distribution, introduction, or manufacture of a controlled substance must be wrongful. Possession, use, distribution, introduction, or manufacture of a controlled substance is wrongful if it is without legal justification or authorization. Possession, use, distribution, introduction, or manufacture of a controlled substance is not wrongful if such act or acts are: (A) done pursuant to legitimate law enforcement activities (for example, an informant who receives drugs as part of an undercover operation is not in wrongful possession); (B) done by authorized personnel in the performance of medical duties; or (C) without knowledge of the contraband nature of the substance (for example, a person who possesses cocaine, but actually believes it to be sugar, is not guilty of wrongful possession of cocaine). Possession, use, distribution, introduction, or manufacture of a controlled substance may be inferred to be wrongful in the absence of evidence to the contrary. The burden of going forward with evidence with respect to any such exception in any court-martial or other proceeding under the code shall be upon the person claiming its benefit. If such an issue is raised by the evidence presented, then the burden of proof is upon the United States to establish that the use, possession, distribution, manufacture, or introduction was wrongful.
(Emphasis added.)
It has been suggested that this Manual provision does not permit the inference of wrongfulness to be drawn at all where
In reaching this conclusion we note that the discussion of this inference in paragraph 213a, Manual for Courts-Martial, United States, 1951, refers to it as a presumption and suggests that the presumption exists “unless the contrary appears.” The original version of paragraph 2136, 1969 Manual, supra, expressly characterized it as an inference which may be drawn “unless the contrary appears.” However, under both rules, the clear intent of the President was to create a permissive inference. More importantly, these types of inferences could still be drawn by the fact-finder if the contrary evidence could “reasonably be disbelieved” by the factfinder. See para. 138a, 1951 Manual, supra, and para. 138a (2), 1969 Manual, supra. See also United States v. West,
In 1969, this additional language was added by the President to paragraph 2136: “If an issue is raised by evidence as to whether possession or use by an accused charged with this offense was innocent on one of these grounds, a showing that it was not innocent on that ground becomes a requirement of proof.” In 1982 this sentence was replaced by the following: “If such an issue is raised by the evidence presented, then the burden of proof is upon the United States to establish that the use, possession, distribution, manufacture, or introduction was wrongful.” Para. 213(g)(5), 1969 Manual, supra (Change 7). In 1984 this wording of the provision was again promulgated by the President in Part IV, paragraph 37(c)(5), 1984 Manual, supra. See also 21 U.S.C. 885(a)(1).
This language did not alter prior practice with respect to the manner in which the prosecution may meet its burden of proof of wrongfulness where the defense introduces contrary evidence. See also R.C.M. 916(b), 1984 Manual, supra. Moreover, it does not expressly bar reliance on the permissive inference of wrongfulness in this context. See Discussion, R.C.M. 916(k)(3)(A). Instead, it simply makes clear that it remains the prosecution’s burden to prove wrongfulness beyond a reasonable doubt and not the defense’s burden to prove beyond a reasonable doubt that the use was innocent. See generally Barnes v. United States, supra at 845 n. 9,
In summary, whether to draw an inference of wrongfulness is a question to be decided by the factfinder using the standard of reasonable doubt. It may be drawn where no contrary evidence is admitted. However, if the prosecution fails to persuade the factfinder beyond a reasonable doubt that this inference should be drawn, a finding of not guilty is required. Similarly, the inference of wrongfulness may be drawn where contrary evidence is admitted. However, if the prosecution fails to persuade the factfinder beyond a reasonable doubt that this contrary evidence should be disbelieved or that the inference should otherwise be drawn, a finding of not guilty is required.
APPLICATION
Turning to the present case, we note that appellant testified that he did not use marihuana during the period in question. He offered testimony from fellow soldiers that he did not exhibit any aberrant behavior indicative of the use of this drug. He finally suggested that a breakdown at the laboratory may have accounted for erroneous test results.
This defense evidence challenges the basis in fact upon which the inference of wrongfulness is predicated. See para. 138a, 1951 and 1969 Manuals, supra. It was offered by the defense to create reasonable doubt in the factfinders’ minds concerning the prosecution’s circumstantial proof of use.
In addition, appellant testified that he did not knowingly use marihuana during the period in question. He suggested a possible explanation that his wife may have secretly planted the drug in his food. He finally offered testimony from a family friend that his estranged wife had the motive, opportunity, and access to the drug to do this act. The prosecution called no witnesses to rebut this defense evidence but argued to the members that such evidence was incredible or improbable and that the inference of wrongfulness should still be drawn.
This defense evidence challenges the existence of the fact to be inferred, wrongfulness and, more particularly, knowledge. Our case law has established that testimony by an accused that he did not knowingly use drugs and cannot honestly account for its presence in his body is sufficient to raise an issue of innocent ingestion. United States v. Grier, 6 U.S.C. M.A. 218,
CONSTITUTIONAL SUFFICIENCY
The findings of guilty in this case reflect that the members rejected appellant’s explanations for the presence of THC (the chemical evidence of marihuana) in his urine. In view of the evidence of record and the military judge’s instructions, it is also clear that they drew an inference from this showing of use that his ingestion was wrongful. The question we must now decide is whether such an inference is alone sufficient to support beyond a reasonable doubt their finding that appellant’s use of marihuana was knowing. See Ulster County Court v. Allen,
In assessing the sufficiency of this inference to support a finding of wrongfulness beyond a reasonable doubt, we find that the military context in which this inference is drawn is particularly important. See Parker v. Levy,
Turning to the particulars involved in drawing this inference and attributing weight to it, we note that this process is predicated on a finding of use of a controlled substance by a servicemember which is not satisfactorily explained to the factfinder. See generally Barnes v. United States, supra at 845,
We again must emphasize that the fact-finder is not required to reach findings of guilty on this basis. Moreover, the Government must convince or persuade the factfinder beyond a reasonable doubt to do so. Our holding today is simply that we find no constitutional violation in findings of guilty to wrongful marihuana use based on such a record.
The decision of the United States Navy-Marine Corps Court of Military Review is affirmed.
Notes
. Federal law expressly provides that proof of knowledge is required for conviction for possession of a controlled substance. 21 U.S.C. § 844(a). See United States v. Holloway,
. The element of knowledge in federal prosecutions for possession of narcotics may be shown by direct or circumstantial evidence. See United States v. Pearson,
. The presumption of knowledge provided in earlier federal statutes concerned a more particular knowledge, e.g., that the drug possessed was imported from a foreign country or illegally imported. See Turner v. United States,
. This argument is a variation of the "bursting bubble” theory of presumptions. See generally United States v. Biesak,
. This argument is a variation of a principle of law sometimes applied in insanity and entrapment cases before federal courts. See United States v. Bueno,
. The following excerpt from paragraph 138(a), Manual for Courts-Martial, United States, 1969 (Revised edition), which was in effect until September 1, 1980, states:
a. Presumptions and permissible inferences.
(1) Presumptions. The term "presumption” is applied to facts which courts are bound to assume in the absence of adequate evidence to the contrary. Examples of presumptions are — An accused person is presumed to be innocent until his guilt is proved beyond a reasonable doubt; and an accused is presumed to have been sane at the time of the offense charged, and to be sane at the time of trial, until a reasonable doubt of his sanity at the time in question is raised by the evidence. See also 148 as to the presumption of competency of witnesses.
These presumptions are procedural rules governing the production of evidence and do not themselves supply evidence.
(2) Permissible inferences. There are a number of permissible inferences encountered in the trial of criminal cases which are sometimes loosely referred to as "presumptions” but which actually are not presumptions at all but are merely well-recognized examples of the use of circumstantial evidence. The drawing of these inferences is not mandatory, and their weight or effect is to be measured only in terms of their logical value. The weight which should be given to any inference will depend upon all the circumstances attending the proved facts which give rise to the inference. The fact that evidence is introduced to show the nonexistence of a fact which might be inferred from proof of other facts does not, if the evidence can reasonably be disbelieved, necessarily destroy the logical value of the inference, but the rebutting evidence must be weighed against the inference. The same is true if the evidence is introduced to show the nonexistence of the facts upon which the inference is based. In drawing and weighing inferences, and in considering evidence introduced in rebuttal thereof, common sense and a general knowledge of human nature and the ordinary affairs of life should be applied.
. We recognize that failure to find use in and of itself would preclude appellant’s conviction for the charged offense. See United States v. Harper,
. The defense evidence in this case did not establish as a matter of law that appellant’s use of marihuana was innocent. Instead, it required the members to infer that his wife secretly planted marihuana in his food without his knowledge. Cf. United States v. Harris, 9 C.M.R. 814, 818 (A.F.B.R.1953). Federal practice in entrapment cases would not require the prosecution to introduce positive countervailing evidence in these circumstances. See United States v. Rosenfeld,
. See Evans v. United States,
