Charges commonly face dismissal recommendations at Article 32 when key witnesses prove unavailable or lack credibility under examination. Victim recantations or refusals to participate often doom prosecutions dependent on their testimony. Witness credibility collapse under cross-examination revealing bias, inconsistencies, or motivation to lie frequently undermines probable cause findings.
Legal insufficiency represents another major dismissal basis when evidence fails to establish offense elements even viewing facts favorably. Jurisdictional defects, statute of limitations expiration, or constitutional violations may mandate dismissal regardless of factual guilt. Immunity grants or pretrial agreement violations sometimes require charge withdrawal.
Evidentiary problems including lost evidence, broken chains of custody, or unlawful collection methods support dismissal recommendations. Expert testimony debunking government theories or establishing impossibility provides powerful dismissal grounds. Alternative suspect evidence or alibi corroboration may eliminate probable cause against accused.
Practical considerations influencing dismissal recommendations include resource expenditure for weak cases, witness trauma from unnecessary proceedings, and command climate impacts from failed prosecutions. PHOs sometimes recommend dismissal while suggesting alternative administrative actions. Political sensitivities in certain case types may override PHO dismissal recommendations, though documented inadequacies influence eventual outcomes. The preliminary hearing serves its screening function by identifying cases inappropriate for court-martial resources.
