The legislative process, the mechanism through which the laws of Missouri are created and enforced, is exciting and dynamic. Legislatures introduce legislation to protect or serve the interests of their constituents. Section 1, Article III of the Missouri Constitution vests legislative powers with the House of Representatives and Senate.

The Senate consists of thirty-four members, who are elected for four-year terms. Senators from odd-numbered districts are elected in presidential election years. Senators from even-numbered districts are chosen in the "off year" elections. Each senator must be at least 30 years of age; a qualified voter of the state for three years; and of the district he represents for one year. The Lieutenant Governor is president and presiding officer of the Senate. In his absence, the President Pro Tem, who is elected by the Senate members, presides.

The House of Representatives consists of 163 members, elected at each general election for two-year terms. A representative must be at least 24 years of age; a qualified voter of the state for two years; and of the district he represents for one year. The House of Representatives is presided over by the Speaker, who is chosen by the members, and in his absence by the Speaker Pro Tem.

The Missouri Constitution provides that new senatorial and representative districts be established after each federal decennial census.
