Territorial Judicial Branch 1869-1890


Prior to the creation of Wyoming Territory, while this region was yet a part of Dakota Territory and under the jurisdiction thereof, the interpretation of the l aw and its enforcement were far from satisfactory. This circumstance was largely due to the great distance lying between Yankton, then capital of Dakota, and the line of population in what is now Wyoming. The coming of the rail road caused an influx of transients, many of whom were most undesirable characters. Crime spread rapidly. The weak judicial set up being unable to cope with the situation, "Judge Lynch" took command. There fore, without legal authority, a temporary government was set up in Cheyenne with a "police" court to try all cases not exceeding two thousand dollars, and a "superior" court to handle cases involving sums greater than th is amount. These courts represented the first attempt at the arduous task of maintaining order in this newly settled country and they succeeded to a surprising degree.

In December of 1867 the Dakota Legislative Assembly convened and mapped out this vast territory into two new counties, Laramie and Carter, to be under the jurisdiction of the second judicial district. A term of court was ordered to be held annually at Cheyenne. The following year Albany and Carbon Counties were defined and placed in the second judicial district with a term of court to be held at Laramie each year.

On July 25, 1868, President Johnson approved the Organic Act of the Territory of Wyoming. According to this Act the judicial power was vested in a supreme court, district courts, probate courts, and justices of the peace. Because of the bitter fight then taking place between the President and Congress the new Territory was not organized until the following April and May. (The last of the Supreme Court Justices was sworn in on May 19, 1869.)

For the time being, until the legislative body of Wyoming Territory should repeal them, the laws of Dakota Territory (except those pertaining to mining) were to remain in effect. Accordingly, the Dakota laws were repealed by the First Legislative Assembly of Wyoming Territory, December 10, 1869, and the new set of laws became effective on January 1, 1870.
