New charges can be added after an Article 32 hearing without reconvening proceedings, but significant limitations apply. Minor or closely related charges that don’t substantially change the nature or gravity of the alleged misconduct may be added through the preferral process. The key consideration is whether the new charges are based on the same transaction or series of events already investigated during the original Article 32 hearing.
If new charges involve substantially different conduct or would materially increase the accused’s potential punishment, the defense can request an additional Article 32 hearing. The military judge evaluates whether proceeding without a new hearing would prejudice the accused’s substantial rights. Factors include whether the defense had opportunity to address the conduct underlying new charges during the original hearing and whether additional investigation would aid the defense.
The prosecution often attempts to avoid reconvening hearings by arguing the new charges are minor, related, or were reasonably within the scope of the original investigation. However, if the charges introduce new theories of criminal liability or arise from previously unknown facts, courts generally favor granting defense requests for additional preliminary hearings. The overarching principle ensures the accused receives adequate notice and opportunity to prepare a defense against all charges they’ll face at trial.
