Yesterday, a three-judge district court preliminarily enjoined Texas’s mid-decade congressional redistricting map. This case will be promptly appealed to the Supreme Court, and it will be the first of many mid-decade redistricting cases on the shadow docket.
The district court’s opinion has a lengthy discussion of the Purcell principle—the notion that courts should not enjoin election laws close to an election. As Rick Hasen and Wilfred Codrington have shown, the Purcell principle is problematic. This post, however, takes Purcell on its own terms and argues that it should not apply to mid-decade redistricting plans.
As an initial matter, Purcell has more bite at the start of the decade. That is because States cannot use their previous maps under one-person, one-vote principles. If a court enjoins a map in early 2022, then the court must draw a new map for the November 2022 election. There is no democratically enacted map to fall back on that complies with the Constitution. That is not true for a mid-decade redistricting. As the three-judge district court pointed out, Texas can still use its 2021 map. Indeed, it is doing so next year for a (long-delayed) special election.
A frequent defense of the Purcell principle is that it avoids voter confusion about what law governs the election. Once again, mid-decade redistricting changes the equation. Voters are used to getting new maps at the start of the decade—a trend that had largely held since the 1960s but is quickly disintegrating. Here, Texas and other mid-decade redistricting states are the ones seeking to change the rules mid-stream.
To be sure, this particular point carries less force in situations where the People have voted on a new map. Thus, California’s Proposition 50 helps minimize voter confusion over which maps will be in place for the 2026 midterms. Similarly, if Missouri voters get to decide whether to keep their new 2025 map, then voter confusion is not a problem there either.
Moreover, applying Purcell to mid-decade redistricting would encourage such behavior, as it gives mapmakers a free bite at the apple to entrench themselves further in office. Given that Purcell is an equitable doctrine, it is capacious enough to factor in such concerns. Indeed, the three-judge district court in this case highlighted that Purcell would encourage gamesmanship by state legislatures bent on mid-decade redistricting, timing their actions to avoid judicial review. And to the extent that Purcell’s embrace of federalism principles is intended to be democracy enforcing, then Purcell is especially ill-suited for mid-decade redistricting plans. Put simply, the motive for mid-decade redistricting is almost always a power grab by politicians at the expense of the People.
One final point. The situation is different when new maps are enacted in response to a court order. That occurred in the Robinson and Callais tango, and the Supreme Court stayed the Callais district court’s injunction, allowing the post-Robinson map to go into force for the 2024 election. In an age of potential defiance of judicial rulings, we should encourage compliance. Giving States the benefit of Purcell in those situations would incentivize that behavior.
