After the first Legislative Assembly, which remained in session much longer in order to establish functional operations of the territorial government, regular annual sessions were scheduled for the second Monday in December and set to run for 40 days.
The 16th Legislative Assembly adjusted the start of future sessions to the second Monday in January, so that the legislature elected in 1867 did not begin meeting until 1868.
Representation in the Legislative Assembly was apportioned by Governor Brigham Young prior to the initial 1851 election by county.
Together with the creation of Emery, San Juan, and Uintah counties, this forced the Legislative Assembly to devise a new redistricting scheme.
[8] Beginning in 1888, legislators were elected from geographic districts instead of by county after the Edmunds-Tucker Act nullified previous apportionments and again required redistricting of the entire territory.
