Plaintiffs challenged Missouri’s mid-decade gerrymander in Cole County Circuit Court, arguing that redrawing lines mid-decade violates Art. III, § 45 of the state constitution, which requires the state to draw new congressional lines when it receives new census data.

Plaintiffs supported by the National Redistricting Foundation (NRF) made a similar claim in Healey v. Missouri in addition to other claims. After the Luther trial court ruled against the mid-decade claim, the case was appealed to the Missouri Supreme Court, and the NRF-supported Healey voters filed an amicus brief in support of the Luther plaintiffs. Unfortunately, the Missouri Supreme Court affirmed the decision of the trial court, holding that the state’s mid-decade gerrymander did not violate the requirement of Art. III, § 45 of the Missouri Constitution that the state draws new congressional lines when it receives new census data.
