Davis v. Bandemer, 478 U.S. 109 (1986), is a case in which the United States Supreme Court held that claims of partisan gerrymandering were justiciable, but failed to agree on a clear standard for the judicial review of the class of claims of a political nature to which such cases belong.

The Democrats argued that "the apportionment unconstitutionally diluted their votes in important districts, violating their rights.

"[3] Indiana Democrats used the elections of November 1982 as proof that the new plan violated the 14th amendment due to voter dilution.

The District Court ruled in favor of the Democrats, throwing out the old plan and calling for the creation of a new one.

[4] The Supreme Court ruled on two separate issues, first whether gerrymandering claims are justiciable and secondly, if the 1981 Indiana Reapportionment Plan was an infraction on citizen's rights to equal representation which was protected by the 14th Amendment.
