Digested under 7 topics
First Principles: Constitutional Matters: Generally
- the Fifth Amendment’s privilege against self-incrimination provides that no person shall be compelled in any criminal case to be a witness against himself; immunity from the use of compelled testimony and evidence derived therefrom is coextensive with the scope of the privilege and is sufficient to compel testimony over a claim of the privilege
- prosecution of appellant on murder charge was not based on his immunized testimony in violation of Fifth Amendment’s privilege against self-incrimination; his immunized testimony did not reveal anything to the government not already known from his prior statements or suggest that appellant was considering an insanity defense, the investigation of appellant was completed prior to his immunized testimony, the decision to prosecute appellant was made long before he gave any immunized testimony, and the prosecutors in appellant’s case were not exposed to immunized testimony
Core Criminal Law Subjects: Crimes: Article 77 - Principals Pre-2019 offenses
- Article 77, UCMJ, imposes liability as a principal on one who (1) assists, encourages, advises, counsels, or commands another in the commission of the offense, and (2) shares in the criminal purpose of design
- the elements of aiding and abetting are: (1) the specific intent to facilitate the crime by another, (2) guilty knowledge on the part of the accused, (3) that an offense was being committed by someone, and (4) that the accused assisted or participated in the commission of the offense
- Article 77, UCMJ, has generally been interpreted to require an affirmative step on the part of the accused; the accused must in some sort associate himself with the venture, in that he participate in it as in something that he wishes to bring about, and that he seek by his action to make it succeed
- while mere presence is not enough to impose liability as an aider or abettor, in some circumstances, inaction may make one liable as a party, where there is a duty to act; if a person has a duty to interfere in the commission of an offense, but does not interfere, that person is a party to the crime if such noninterference is intended to and does operate as an aid or encouragement to the actual perpetrator
- evidence was legally sufficient to establish that appellant had the requisite specific intent and knowledge for aiding and abetting the wrongful placing of a weapon on the body of a dead Iraqi national in violation of Article 134, UCMJ, even though his team leader actually placed the weapon with the body, where rational court members could have concluded from the evidence that both soldiers intended to kill the victim and stage the scene to make it appear that he was a combatant carrying an AK-47; appellant completed his part by taking the affirmative act of shooting the victim in the head; his team leader completed his part by staging the weapon on the body; appellant participated in the offense by setting the stage for the offense and later participating in the cover-up of the incident; although the murder of the victim and the placement of the weapon were charged in a discrete manner, the members were free to review all the evidence in determining whether appellant was guilty of the offenses; based on the evidence as a whole, rational court members could have concluded beyond a reasonable doubt that appellant had the specific intent to facilitate his team leader’s act of placing the weapon with the body, and that he actively participated in his team leader’s staging of the scene by ensuring the death of the victim
Core Criminal Law Subjects: Evidence: Immunized Testimony
- the Fifth Amendment’s privilege against self-incrimination provides that no person shall be compelled in any criminal case to be a witness against himself; immunity from the use of compelled testimony and evidence derived therefrom is coextensive with the scope of the privilege and is sufficient to compel testimony over a claim of the privilege
- the government may prosecute an immunized witness where it can demonstrate that it has made neither direct nor indirect use of the testimony
- in order to prosecute an immunized witness who has given compelled testimony, the government must affirmatively prove by a preponderance of the evidence that its evidence is derived from a legitimate source wholly independent of the compelled testimony; the grant of immunity must leave the witness and the government in substantially the same position as if the witness had claimed his privilege in the absence of a state grant of immunity
- prosecution of appellant on murder charge was not based on his immunized testimony in violation of Fifth Amendment’s privilege against self-incrimination; his immunized testimony did not reveal anything to the government not already known from his prior statements or suggest that appellant was considering an insanity defense, the investigation of appellant was completed prior to his immunized testimony, the decision to prosecute appellant was made long before he gave any immunized testimony, and the prosecutors in appellant’s case were not exposed to immunized testimony
Core Criminal Law Subjects: Evidence: Intent
- intent, like other mental states, can be shown by circumstantial evidence
Core Criminal Law Subjects: Burdens, Standards, Presumptions, Inferences: Trial Burdens, Standards › Immunity
- in order to prosecute an immunized witness who has given compelled testimony, the government must affirmatively prove by a preponderance of the evidence that its evidence is derived from a legitimate source wholly independent of the compelled testimony; the grant of immunity must leave the witness and the government in substantially the same position as if the witness had claimed his privilege in the absence of a state grant of immunity
- whether the government has shown by a preponderance of the evidence that it has based appellant’s prosecution on sources independent of the immunized statements is a preliminary question of fact
Trial Stages: Merits: Findings
- even though the members must keep the evidence of each offense separate, if evidence has been presented which is relevant to more than one offense, they may consider that evidence with respect to each offense to which it is relevant
Trial Stages: Appeals: Standards of Review, Burdens, etc.
- the test for legal sufficiency is whether, after viewing the evidence in the light most favorable to the prosecution, any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt; this familiar standard gives full play to the responsibility of the trier of fact to draw reasonable inferences from basic facts to ultimate facts; the factfinder’s role as weigher of the evidence is preserved through a legal conclusion that upon judicial review all of the evidence is to be considered in the light most favorable to the prosecution
- whether the government has shown by a preponderance of the evidence that it has based appellant’s prosecution on sources independent of the immunized statements is a preliminary question of fact; an appellate court will not overturn a military judge’s resolution of this question unless it is clearly erroneous or is unsupported by the evidence
- in reviewing for clear error, an appellate court asks whether, on the entire evidence, it is left with the definite and firm conviction that a mistake has been committed
