Redistricting litigation does not happen in a vacuum. It is a highly coordinated, multi-state cascade where tactical failures in one jurisdiction immediately establish the legal precedent used to aggressively gerrymander the next. Knowing the theory of MAUP (Module 6) is useless if you don't know how it survives in court. This module functions as a rapid-fire case block, tracking a single decade of brutal litigation in North Carolina (which culminated in the terrifying "Independent State Legislature" theory) and the desperate, high-stakes defense of minority opportunity districts in Alabama and Louisiana.
In This Module
- Covers: The modern landscape of post-2020 redistricting, North Carolina's Moore v. Harper case, and Alabama's Allen v. Milligan case.
- Why it matters: State legislatures redraw maps immediately after taking power, ignoring court orders for as long as possible. By studying these cases, practitioners learn how to anticipate legislative defiance rather than assuming the courts will magically fix the map.
- After this module, the reader can: Connect the granular map-making tools of Course 2 directly to the federal and state litigation required to keep the maps legal.
Reading List
Start Here
-
A high-level view of the map-making battlefield. Li provides a devastating summary of how the 2020 Census data was instantly weaponized into gerrymandered outcomes across Texas, North Carolina, and Georgia. It contrasts states completely captured by partisan legislatures against those buffered by Independent Redistricting Commissions (like California).
-
The culmination of North Carolina's brutal decade of map manipulation. When the NC State Supreme Court struck down the legislature's gerrymander, the legislature appealed to SCOTUS using the "Independent State Legislature theory"—arguing that state courts and state constitutions have absolutely zero authority to stop legislatures from rigging federal elections. While the Court rejected the most extreme version of the theory, the case exposes the outer limits of democratic hostility.
Going Deeper
-
A shocking, unexpected victory for the VRA. Alabama's population is 27% Black, yet the state legislature drew maps packing Black voters into only 1 of 7 districts (14%). Against all expectations, a conservative Supreme Court upheld Section 2, forcing Alabama to draw a second minority-opportunity district. Read this to understand how MAUP packing is legally defeated in modern courts.
For Legal and Policy Practitioners
-
Never just read the final opinion; read the brief that forced it. The LDF's amicus brief explicitly tackles the state’s argument that its maps were "race-neutral." It provides a masterclass on how to argue that "compactness" (a geometric standard) cannot be used as a legal shield to systematically exclude a demographic community from representation.
Core Concepts & Inquiries
What was the Independent State Legislature theory?
The theory argued that state courts and state constitutions have absolutely zero authority to stop state legislatures from rigging federal elections. While the Supreme Court rejected the most extreme version of the theory in Moore v. Harper (2023), the case exposed the outer limits of anti-democratic hostility and the willingness to remove all judicial checks on legislative map manipulation.
What did Allen v. Milligan decide about racial gerrymandering?
Alabama's population is 27% Black, yet the legislature drew maps packing Black voters into only 1 of 7 congressional districts. Against all expectations, a conservative Supreme Court upheld Section 2 of the VRA, forcing Alabama to draw a second minority-opportunity district. The case demonstrates how MAUP-based packing is legally defeated in modern courts.
Why is redistricting litigation described as a multi-state cascade?
Redistricting litigation is coordinated across jurisdictions because tactical failures in one state immediately establish legal precedent used to aggressively gerrymander the next. A loss in North Carolina shapes the legal landscape for challenges in Alabama and Louisiana, making each case a strategic domino in a national battle.
How do legislatures defy court-ordered redistricting?
State legislatures commonly redraw maps immediately after taking power, then ignore or delay compliance with court orders for as long as possible. By the time a community wins a lawsuit, multiple election cycles may have already been governed by the illegal maps, effectively locking in the structural advantages the gerrymander was designed to produce.
Goal: Measure the structural exposure of your community to legislative capture.
North Carolina’s chaos is the direct result of a system where politicians draw their own lines. Add this structural baseline to your Jurisdiction Electoral Analysis:
- Who Draws the Lines? Research the redistricting law in your state. Does the state legislature draw the state and congressional maps, or does an Independent Redistricting Commission (IRC), or a politician-appointed commission?
- The Override Mechanism: If your state uses a commission, does the state legislature possess the legal power to overrule the commission’s final map? (e.g., Ohio's broken commission system).
Determine if your map is insulated from the legislature, or if you are entirely exposed to the exact dynamics seen in North Carolina and Alabama.
