In brief
Overview
The case challenges a Wisconsin redistricting plan that the appellees say is so extreme it effectively nullifies democracy.
According to Appellants, the Court has never identified judicially manageable standards for deciding when politicians have acted too politically in drawing district lines.
Background and question before the Court
Oral argument began before the Supreme Court at 10:04 a.m.
Justices asked what data, criteria, and constitutional standards are needed to determine whether a partisan redistricting plan violates the Constitution.
What each side argues
Appellants
The appellants argue that the Court lacks manageable standards and that the plaintiff’s social‑science metrics do not resolve the problem.
According to Mr. Smith, in Vieth the Court said that to impose a new standard the parties must provide substantially more evidence than they have done here.
Appellees
The appellees contend that the challenged map is an extreme partisan gerrymander that pre‑decides political control for a decade, effectively nullifying democracy.
What happened at oral argument
Justice Gorsuch asked what data and criteria (e.g., two‑year cycles, efficiency gap) are needed to define a constitutional standard for redistricting.
Justice Ginsburg asked whether, in Wisconsin, a large number of uncontested districts effectively eliminates competition.
Justice Kennedy asked whether a state law or amendment that mandates using all legitimate factors to favor a particular party is lawful.
Justice Kennedy further asked whether such a law would violate the Equal Protection Clause or the First Amendment.
Justice Sotomayor asked what value extreme partisan gerrymandering has for democracy.
According to Justice Alito, justice Alito questioned why the alleged violation should be considered de minimis, suggesting it is not.
Justice Kagan asked whether a resident of an overpopulated district has standing to challenge the entire state map.
Justice Kagan also asked what threshold should trigger a court‑ordered redrawing of a map and where the line should be drawn.
