Sioux Indian Courts / An address delivered by Doane Robinson before the South Dakota Bar Association, at Pierre, South Dakota, January 21, 1909

It is not an easy thing to determine the laws or the practices of an unlettered people, who have abandoned the wild and primitive life to live under regulations prescribed by their conquerors, and who must depend upon tradition and recollection for the practices of the old life; but fortunately intelligent observers have from time to time, during the past two and one half centuries, noted their observations, and these, supplemented by the recollections of the older men now living, give to us a fairly clear understanding of the courts and the legal practices of these people.
The judges of these courts were usually twelve in number and held their places by hereditary right, though occasionally some low caste man, through some brilliant exploit would break into this exclusive and aristocratic circle and sometimes even exercised dominating influence which the aristocrats dared not oppose, though he was still regarded as a plebian upstart, and was despised by the upper ten, and his rank died with him. Ordinarily from seven to twelve judges sat for the trial of causes, but sometimes even a greater number were permitted. The civil court in time of peace took cognizance of civil and criminal matters arising in the band. Civil actions usually grew out of disputes about the ownership of property and the court patiently heard the testimony of the parties and witnesses and at once determined the ownership of the article, delivered it to the successful litigant and the decision was never reviewed or questioned. A majority of the court determined the judgment.
Among the duties of this court was to determine the limits of each day's march when out upon a campaign, and to regulate the camping places. This was an important function, for the army subsisted off the country and unless the utmost care was exercised the base of supplies would be frightened away and the band subjected to starvation.
It was not until after the Red Cloud war ended in 1868 that the courts for Indian offenses, equipped by the Indian themselves, began to be tried at some of the agencies in a small way. The Sissetons and Santees were first to give them a trial and eventually they were supplied to all the Reservations except the Rosebud, which, for some reason of which I have been unable to secure information, has never had them.
