No, a military prosecutor cannot rely solely on a drug test from a civilian lab that lacks Department of Defense (DoD) accreditation and expect it to be easily admitted as evidence in a court-martial. The military drug testing program is held to an extremely high standard of scientific and forensic reliability. All DoD drug testing labs undergo a rigorous certification process to ensure their procedures are flawless. This gives their results a legal “presumption of regularity.”
A test result from a non-accredited civilian lab does not have this presumption. For the result to be admissible, the prosecutor would have to establish a full scientific foundation for the test from scratch. This would involve calling expert witnesses from the civilian lab to testify about their specific testing methodology, their quality control procedures, their machine calibration records, and their personnel qualifications. The entire process would be open to a vigorous challenge by the defense.
A military defense attorney would file a motion to suppress the result from the non-accredited lab. They would argue that it is not sufficiently reliable to be used as evidence in a criminal proceeding. The attorney would hire their own expert toxicologist to scrutinize the civilian lab’s procedures and highlight any flaws or deviations from the high standards set by the DoD. It is very likely that a military judge would find the result from a non-DoD-accredited lab to be inadmissible for lack of a proper scientific foundation.
