Art. 63. The functions of the engineers being generally confined to the most elevated branch of military science, they are not to assume, nor are they subject to be ordered on any duty beyond the line of their immediate profession, except by the special order of the president of the U. States; but they are to receive every mark of respect, to which their rank in the army may entitle them, respectively, and are liable to be transferred, at the discretion of the president, from one corps to another, regard being paid to rank.
Art. 64. General courts-martial may consist of any number of commissioned officers, from five to thirteen, inclusively, but they shall not consist of less than thirteen, where that number can be convened, without manifest injury to the service.
Art. 65. Any general officer commanding an army, or colonel commanding a separate department, may appoint general courts-martial, whenever necessary. But no sentence of a court-martial shall be carried into execution until after the whole proceedings shall have been laid before the officer ordering the same, or the officer commanding the troops for the time being; neither shall any sentence of a general court-martial, in time of peace, extending to the loss of life, or the dismission of a commissioned officer, or which shall, either in time of peace or war, respect a general officer, be carried into execution, until after the whole proceedings shall have been transmitted to the secretary of war, to be laid before the president of the U. States, for his confirmation or disapproval, and orders in the case. All other sentences may be confirmed and executed by the officer ordering the court to assemble, or the commanding officer, for the time being, as the case may be.
Art. 66. Every officer commanding a regiment, or corps, may appoint, for his own regiment, or corps, courts-martial, to consist of three commissioned officers, for the trial and punishment of offences, not capital, and decide upon their sentences. For the same purpose, all officers, commanding any of the garrisons, forts, barracks, or other places, where the troops consist of different corps, may assemble courts-martial, to consist of three commissioned officers, and decide upon their sentences.
Art. 67. No garrison, or regimental court-martial shall have the power to try capital cases, or commissioned officers; neither shall they inflict a fine exceeding one month’s pay, nor imprison, nor put to hard labor, any non-commissioned officer or soldier, for a longer time than one month.
Art. 68. Whenever it may be found convenient and necessary to the public service, the officers of the marines shall be associated with the officers of the land forces, for the purpose of holding courts-martial and trying offenders belonging to either; and in such cases the orders of the senior officer of either corps, who may be present and duly authorised, shall be received and obeyed.
Art. 69. The judge advocate, or some person deputed by him, or by the general or officer commanding the army, detachment, or garrison, shall prosecute in the name of the U. States, but shall so far consider himself as counsel for the prisoner, after the said prisoner shall have made his plea, as to object to any leading question to any of the witnesses, or any question to the prisoner, the answer to which might tend to criminate himself; and to administer to each member of the court, before they proceed upon any trial, the following oath, which shall also be taken by all members of the regimental and garrison courts-martial:
“You A. B. do swear that you will well and truly try and determine, according to evidence, the matter now before you, between the United States of America and the prisoner to be tried; and that you will duly administer justice, according to the provisions of ‘An act establishing rules and articles for the government of the armies of the United States,’ without partiality, favor, or affection: and if any doubt shall arise, not explained by said articles, according to your conscience, the best of your understanding, and the custom of war in like cases: and you do further swear, that you will not divulge the sentence of the court until it shall be published by the proper authority: neither will you disclose or discover the vote or opinion of any particular member of the court-martial, unless required to give evidence thereof as a witness, by a court of justice, in a due course of law. So help you God.”
And as soon as the said oath shall have been administered to the respective members, the president of the court shall administer to the judge advocate, or person officiating as such, an oath in the following words:
“You A. B. do swear, that you will not disclose or discover the vote or opinion of any particular member of the court-martial, unless required to give evidence thereof as a witness, by a court of justice in due course of law; nor divulge the sentence of the court to any but the proper authority, until it shall be duly disclosed by the same. So help you God.”
