Article 32 hearings and Article 15 proceedings serve fundamentally different purposes within military justice. Article 32 provides preliminary investigation of charges potentially headed to court-martial, examining probable cause and disposition recommendations without determining guilt. Article 15 constitutes actual nonjudicial punishment proceedings where commanders determine guilt and impose punishment for minor offenses without formal trial.
Procedural differences include Article 32’s formal hearing structure with appointed PHO, witness testimony, and evidence presentation versus Article 15’s informal commander-led process. Article 32 involves legal counsel representation and discovery rights while Article 15 proceedings permit consultation but not formal representation. The standard differs between probable cause evaluation at Article 32 versus beyond reasonable doubt determination for Article 15 guilt findings.
Consequences vary dramatically, with Article 32 producing only recommendations while Article 15 results in actual punishment including reduction, forfeitures, and restriction. Article 15 creates disciplinary record affecting career progression while Article 32 participation carries no direct consequences. Service members can refuse Article 15 demanding court-martial, but cannot refuse Article 32 hearings for preferred charges.
The relationship sometimes overlaps when PHOs recommend NJP instead of court-martial, though subsequent Article 15 proceedings remain separate. Evidence from Article 32 hearings may inform Article 15 decisions if charges are withdrawn for nonjudicial disposition. The distinct procedures reflect different military justice needs between preliminary investigation and actual disciplinary action.
