Modifies term limits for members of the general assembly and the number of members of the house of representatives

HJR 121 proposes a constitutional amendment to reduce Missouri's House of Representatives from 163 to 103 members after the 2030 census. It establishes new redistricting rules requiring districts to be nearly equal in population (within 3% deviation), comply with federal voting rights laws, and preserve communities by following county boundaries where possible. If approved by voters in 2026, this amendment would directly affect how legislative districts are drawn and the number of representatives elected in Missouri. The bill does not address term limits, as suggested by its title, but focuses solely on structural changes to the House size and redistricting process.
