Mental health defenses can be previewed during Article 32 hearings to influence disposition recommendations, though extensive expert testimony typically awaits trial. Preliminary hearings allow introducing mental health evidence relevant to whether charges should proceed, including diagnosis documentation suggesting lack of criminal responsibility, treatment records demonstrating diminished capacity, and expert affidavits explaining condition relevance to charges. PHOs should consider whether mental health issues make alternative disposition more appropriate than trial.
Strategic preview decisions balance educating government about defense strength potentially encouraging favorable pleas against revealing expert opinions enabling government preparation or rebuttal. Limited preview might include establishing diagnosed conditions without detailed offense connection, demonstrating ongoing treatment compliance suggesting rehabilitation, highlighting service-connected mental health issues generating sympathy, or presenting mitigation for disposition without contesting guilt. Full mental health defenses usually require extensive expert preparation premature for preliminary hearings.
Practical limitations include expert availability for preliminary hearings versus trial, costs for multiple expert appearances across proceedings, and preliminary hearing time constraints limiting detailed testimony. Government cross-examination at preliminary hearings may reveal defense weaknesses or generate harmful admissions. RCM 706 sanity boards may be requested based on preliminary hearing revelations, potentially delaying proceedings while providing valuable evaluation.
The balance involves showing enough mental health mitigation to influence charging decisions without compromising trial defenses through premature or incomplete presentation. Success often comes through documentary evidence and limited expert testimony establishing credible mental health involvement warranting further evaluation rather than attempting complete defenses at preliminary stages. PHO receptiveness to mental health evidence varies with legal sophistication and military experience understanding service-connected conditions.
