See also R.C.M. 915 (Mistrial). When charges that have been withdrawn from a court-martial are referred to another court-martial, the reasons for the withdrawal and later referral should be included in the record of the later court-martial, if the later referral is more onerous to the accused. Therefore, if further prosecution is contemplated at the time of the withdrawal, the reasons for the withdrawal should be included in or attached to the record of the earlier proceeding. Improper reasons for withdrawal include an intent to interfere with the free exercise by the accused of constitutional rights or rights provided under the UCMJ, or with the impartiality of a court-martial. A withdrawal is improper if it was not directed personally and independently by the convening authority, a special trial counsel, or a superior competent authority. Whether the reason for a withdrawal is proper, for purposes of the propriety of a later referral, depends in part on the stage in the proceedings at which the withdrawal takes place. Before arraignment, there are many reasons for a withdrawal that will not preclude another referral. These include receipt of additional charges, absence of the accused, reconsideration by the convening authority, a special trial counsel, or a superior competent authority of the seriousness of the offenses, questions concerning the mental capacity of the accused, and routine duty rotation of the personnel constituting the court-martial. Charges withdrawn after arraignment may be referred to another court-martial under some circumstances. For example, it is permissible to refer charges that were withdrawn pursuant to a plea agreement if the accused fails to fulfill the terms of the agreement. See R.C.M. 705. Charges withdrawn after some evidence on the general issue of guilt is introduced may be re-referred only under the narrow circumstances described in the rule.
