In brief
Overview
According to Appellants, rucho v. Common Cause concerns whether partisan gerrymandering claims are justiciable and what standard should apply to evaluate them.
Background and question before the Court
Justice Ginsburg asked whether one person has one vote that counts equally if the impact of her vote is reduced based on party affiliation.
Justice Breyer asked about the relevance of a two‑thirds majority standard in the context of partisan gerrymandering.
What each side argues
Appellants (Rucho)
The appellants argue that the Court has repeatedly failed to identify a justiciable standard for partisan gerrymandering claims.
According to Appellants, they contend that partisanship must be a material factor, and in this case it was the predominant factor supporting the lower court’s ruling.
Appellees (Common Cause)
According to Mr. Bondurant, the appellees argue that intentional discrimination against political parties and voters based on their political views violates constitutional principles.
