32 CFR §150.17

1. (a)
   1. (1)A party may suggest the appropriateness of consideration or reconsideration by the Court as a whole. Such consideration or reconsideration ordinarily will not be ordered except:
      1. (i)When consideration by the full Court is necessary to secure or maintain uniformity of decision, or
      2. (ii)When the proceedings involve a question of exceptional importance, or
      3. (iii)When a sentence being reviewed pursuant to Article 66 extends to death.
   2. (2)In cases being reviewed pursuant to Article 66, a party's suggestion that a matter be considered initially by the Court as a whole must be filed with the Court within 7 days after the government files its answer to the assignment of errors, or the appellant files a reply under § 150.15(b). In other proceedings, the suggestion must be filed with the party's initial petition or other initial pleading, or within 7 days after the response thereto is filed. A suggestion for reconsideration by the Court as a whole must be made within the time prescribed by § 150.19 for filing a motion for reconsideration. No response to a suggestion for consideration or reconsideration by the Court as a whole may be filed unless the Court shall so order.
2. (b)The suggestion of a party for consideration or reconsideration by the Court as a whole shall be transmitted to each judge of the Court who is present for duty, but a vote need not be taken to determine whether the cause shall be considered or reconsidered by the Court as a whole on such a suggestion made by a party unless a judge requests a vote.
3. (c)A majority of the judges present for duty may order that any appeal or other proceeding be considered or reconsidered by the Court sitting as a whole. However, en banc reconsideration of an en banc decision will not be held unless at least one member of the original majority concurs in a vote for reconsideration.
4. (d)This rule does not affect the power of the Court sua sponte to consider or reconsider any case sitting as a whole.
