These efforts accelerated after the U.S. Supreme Court docket in 2019 restricted the ability of federal courts to dam such maps.
“Basically, every one of the 50 states has something in its constitution that could be used to constrain partisan gerrymandering,” stated Samuel Wang, director of the Princeton Gerrymandering Challenge.
State constitutions, that are interpreted by state supreme courts, usually have language that echoes the fitting to freedom of speech and affiliation discovered within the First Modification to the U.S. Structure, Wang stated. Additionally they embody a proper to equal safety beneath the legislation, much like the 14th Modification.
Some state constitutions assure free and truthful elections, language that doesn’t seem within the U.S. Structure. Thirty states have some type of a constitutional requirement free of charge elections, in line with the Nationwide Convention of State Legislatures.
Not less than 10 state supreme courts have discovered that state courts can determine instances involving allegations of partisan gerrymandering, in line with a 2024 evaluation by the State Democracy Analysis Initiative on the College of Wisconsin Regulation Faculty.

Breaking out of lockstep
As federal courts restrict their evaluation of gerrymandering due to U.S. Supreme Court docket selections, some state supreme courts are reluctant to wade into the problem due to a follow known as “lockstepping.”
State supreme courts usually interpret their state constitutions consistent with — or in lockstep with — how the U.S. Supreme Court docket views comparable language within the U.S. Structure.

Court docket-imposed limits quantity to violations of the normal separation of powers, they are saying, with the judiciary overstepping its authority to intervene in politics.
“We expect them to be nonpartisan. We expect them to be unbiased. We expect them to be fair. We expect them to read the constitution and to protect or at least respect the separation of powers,” stated Utah Republican state Rep. Casey Snider, talking of Utah courts throughout a flooring speech earlier this month.
In Utah, state courts waded by way of a yearslong authorized battle over whether or not state lawmakers should undertake a non-gerrymandered map. After the Republican-controlled legislature repealed and changed an impartial redistricting course of, the Utah Supreme Court docket final 12 months dominated lawmakers had violated the state structure.
A Utah district courtroom decide in November then adopted a congressional map that may doubtless lead subsequent 12 months to the election of a Democrat. The state’s 4 congressional seats are at the moment all held by Republicans.

Constitutional considerations

The vote got here after a flooring debate the place opponents raised considerations about limiting courtroom involvement; the laws included a provision sending any authorized problem on to the Indiana Supreme Court docket, bypassing a jury trial.
Indiana Republican state Sen. Greg Walker stated the measure violated the state structure, which ensures an “inviolate” proper to a jury trial in all civil instances. “In legal terms, ‘inviolate’ has the implication of being sacred, as opposed to being just a piece of the law,” Walker stated on the ground.
State Sen. Mike Gaskill, a Republican who sponsored the map, stated throughout a speech that Indiana residents would profit from a fast course of to resolve authorized challenges. “Both sides, in any case, want them to be settled quickly so that they don’t cause chaos and interruptions in the elections process,” he stated.
If the map had handed, opponents would have doubtless attacked the measure utilizing a provision of the Indiana Structure that requires “free and equal” elections.
