Under the provisions of a constitutional amendment adopted in November, 1920, the voters of Missouri, at a special election in August, 1921, approved the plan for a constitutional convention, to consist of two delegates from each of the 34 senatorial districts and 15 delegates elected at large. In order to secure representation from different political parties the amendment restricted each party to the nomination of one candidate for delegate in each senatorial district. The state committees of the two major political parties agreed also to the nomination by each of seven candidates for delegates-at-large, and jointly nominated a candidate for the fifteenth delegate-at-large, so that the convention was bipartisan in its membership. This arrangement prevented the consideration of questions involving party differences, except in one case where agreement was secured upon a compromise plan.

The convention met on May 16, 1922 and adjourned sine die on November 6, 1923, after having been in session 267 working days. On account of the session of the legislature a recess was taken from December 15, 1922 to April 16, 1923. The convention continued to meet until September 7, 1923, when another recess was taken to enable the committees on phraseology and arrangement, submission and address, and others to complete their reports. The convention reassembled on October 2, 1923 and completed its work on October 5. In order to provide for any contingency that might arise it was decided to reconvene on November 6, with the understanding that the president and secretary with such delegates as might be present could declare the convention finally adjourned.
