Fact check: Which states have successfully implemented redistricting in non-census years without court challenges?

1. Summary of the results

Based on the analyses provided, none of the sources contain specific examples of states that have successfully implemented redistricting in non-census years without court challenges ^{[1] [2] [3] [4] [5] [6]}. The sources consistently indicate that while states are not legally prohibited from redrawing maps between censuses, this practice is rarely undertaken ^[1].

The analyses reveal that:

• Some states have attempted to de-politicize redistricting by establishing commissions rather than allowing lawmakers to handle the process ^[1]
• Mid-decade redistricting is uncommon enough that there is proposed legislation to prohibit it entirely ^[4]
• Texas has been a focal point for discussions about non-census year redistricting, with Republican-led efforts facing Democratic opposition and potential court challenges ^{[1] [5]}

2. Missing context/alternative viewpoints

The original question assumes that successful non-census year redistricting without court challenges is a documented phenomenon, but the analyses suggest this may be an extremely rare or non-existent practice. Several important contextual elements are missing:

• The Supreme Court has given states "increasingly unfettered power in redistricting" over the past decade, which could theoretically make non-census redistricting more feasible ^[1]
• There are ongoing efforts to create national legislation that would prohibit mid-decade redistricting entirely, suggesting this practice is viewed as problematic ^[4]
• The rarity of non-census redistricting may be due to the high likelihood of court challenges rather than successful implementation without them ^{[1] [5]}

Political parties and redistricting organizations would benefit from different narratives: Republicans might benefit from promoting the idea that non-census redistricting is legally permissible and sometimes successful, while Democrats and redistricting reform advocates would benefit from emphasizing that such attempts typically face legal challenges.

3. Potential misinformation/bias in the original statement

The original question contains an implicit assumption that may not reflect reality. By asking "which states have successfully implemented redistricting in non-census years without court challenges," it presupposes that such cases exist and are documented. However, the analyses consistently indicate that this practice is rare and that specific successful examples are not readily available in the literature ^{[1] [2] [3] [4] [5] [6]}.

The question may inadvertently promote the misconception that non-census redistricting is a common or well-documented practice, when the evidence suggests it is exceptional and typically controversial. This framing could benefit those seeking to normalize or legitimize mid-decade redistricting efforts by implying precedent exists where it may not.
