Digested under 6 topics

First Principles: Constitutional Matters: Confrontation

  1. the Sixth Amendment provides that in all criminal prosecutions, the accused shall enjoy the right to be confronted with the witnesses against him; this permits the admission of testimonial statements of a witness absent from trial only where the declarant is unavailable, and the accused has had a prior opportunity to cross-examine
  2. a laboratory nucleic acid amplification test report for gonorrhea was not testimonial in nature, and thus admission of the lab report, without any testimony from a laboratory employee, did not violate accused's Sixth Amendment Confrontation Clause rights, where the primary purpose of the test was diagnostic and not evidentiary with an eye toward litigation, and where there was no involvement by law enforcement in requesting the test, because the test was ordered from a private lab by a private physician who, upon receiving the results, prescribed a confirmatory test and treatment by another private medical facility; although the physician was aware of the possible law enforcement related consequences of the exam and test results, she was acting as a medical provider, not as an arm of law enforcement, in requesting the test

Core Criminal Law Subjects: Evidence: Expert / Scientific Testimony

  1. a laboratory nucleic acid amplification test report for gonorrhea was not testimonial in nature, and thus admission of the lab report, without any testimony from a laboratory employee, did not violate accused's Sixth Amendment Confrontation Clause rights, where the primary purpose of the test was diagnostic and not evidentiary with an eye toward litigation, and where there was no involvement by law enforcement in requesting the test, because the test was ordered from a private lab by a private physician who, upon receiving the results, prescribed a confirmatory test and treatment by another private medical facility; although the physician was aware of the possible law enforcement related consequences of the exam and test results, she was acting as a medical provider, not as an arm of law enforcement, in requesting the test
  2. a Daubert (509 US 579 (1993)) error is nonconstitutional in nature
  3. in this case, even assuming that the military judge abused his discretion in admitting a laboratory test result based on an erroneous application of the Daubert (509 US 579 (1993)) factors, appellant was not prejudiced by the test’s admission where the government’s case was strong based on the comprehensive digital forensic evidence, the testimony of the government’s witnesses, and appellant’s own admissions, where the accused's case was weak and improbable, and where the test result was not so material or qualitatively significant as to effect the members' findings of guilt after the defense significantly diminished the materiality and reliability of the non-conclusive test result

Trial Stages: Appeals: Harmless / Prejudicial Error

  1. under Article 59(a), UCMJ, the finding or sentence of a court-martial may not be held incorrect on the ground of an error of law unless the error materially prejudices the substantial rights of the accused
  2. for nonconstitutional evidentiary errors, the test for prejudice is whether the error had a substantial influence on the findings; the government bears the burden of demonstrating that the admitted evidence was not prejudicial; in conducting the prejudice analysis, an appellate court weighs: (1) the strength of the government’s case, (2) the strength of the defense case, (3) the materiality of the evidence in question, and (4) the quality of the evidence in question; and when assessing the materiality and quality of the evidence, the court considers the particular factual circumstances of each case

Trial Stages: Appeals: Standards of Review, Burdens, etc.

  1. an appellate court reviews de novo whether statements are testimonial for purposes of the Sixth Amendment
  2. in determining whether a statement is testimonial, an appellate court asks whether it would be reasonably foreseeable to an objective person that the purpose of any individual statement is evidentiary, considering the formality of the statement as well as the knowledge of the declarant; in the end, the question is whether, in light of all the circumstances, viewed objectively, the primary purpose of the statement was to create an out-of-court substitute for trial testimony
  3. under Article 59(a), UCMJ, the finding or sentence of a court-martial may not be held incorrect on the ground of an error of law unless the error materially prejudices the substantial rights of the accused
  4. for nonconstitutional evidentiary errors, the test for prejudice is whether the error had a substantial influence on the findings; the government bears the burden of demonstrating that the admitted evidence was not prejudicial; in conducting the prejudice analysis, an appellate court weighs: (1) the strength of the government’s case, (2) the strength of the defense case, (3) the materiality of the evidence in question, and (4) the quality of the evidence in question; and when assessing the materiality and quality of the evidence, the court considers the particular factual circumstances of each case
